Connecting PMM

Dishwashers save water many times over, especially if you wash dishes like soap and water - under running water. And they run on cold water. Some models can be hot, but my husband and I decided that it costs less to heat the water than to use hot water over the counter.

Request to everyone !!
My question is not about the machine itself, but about how you have it connected. The fact is that we have a rented apartment, the house is 30 years old. old pipes, really want a car. but, I understand that most likely this is impossible, but still I want to ask you to take a picture of how she joins the pipes with you, and suddenly everything is not as scary as it seems to me.

Of course, not so scary, it would be a place. It is connected through a special tee (cold water goes into the sink and into the dishwasher) in any household. store is for sale. I also have a tap for the dishwasher.
A tee for sewerage is also sold.
I can only show my connection in a couple of hours.
Our friends also live in an old house, their BOSCH car is connected to old pipes
The tee is something like this (there are different)

Here's another thing I found

Installing the dishwasher
Dishwasher connection.

It is important to remember that the connection of the dishwasher must be carried out strictly in accordance with the instructions for use and technical safety standards. In case of violation of the recommendations, the guarantee provided by the manufacturer may be voided. There is also a risk of leakage if this household appliance is incorrectly connected.

When connecting the dishwasher, you must:
To install the dishwasher, it is necessary to install a separate electrical line (cable PVS3x1.5) from the switchboard with automatic machines. A socket with an earthing contact is installed on one side of the line, and an automatic 16a on the other. When connecting the dishwasher, it is strictly not recommended to use household sockets for connection, since the cable section of the dishwasher does not correspond to the outlet standard; also, the power consumption of the device is 2-2.5 kW, which, without using a separate machine and grounding, can lead to a life-threatening situation.

When connecting the dishwasher, it is important to ensure the correct connection and water supply. To do this, it is necessary to install a shut-off valve, that is, a tee with an angle valve is used to connect the riser to the mixer with a flexible connection, or in its absence, a drain is installed with the subsequent installation of the valve. To connect the dishwasher and the faucet, use a standard hose, which can be extended if necessary using a 1 / 2x / 3/4 fitting, etc. If the water quality is poor, it is recommended to use a coarse filter. If there is an akvostop in the dishwasher, its installation requires more attention.

To organize the drainage of the used water, you can use a drain hose (the simplest, but far from effective way is to hang it on the edge of the bathtub, sink or toilet bowl). You can also install a tee in the sewer; in the standard siphon of the apartment; replace the siphon with a special siphon with a branch for connecting the drain hose. The drain hose can be lengthened if necessary (but remember that in this case the drain hose will be limited in length). For the reliability of the connections when organizing the drain, clamps and couplings are used.

When installing the dishwasher, it is necessary, first of all, to carefully remove it from the packaging, to install it in the place of further operation and to exclude vibration - to level it in different planes.Built-in devices are mounted inside the compartment, after which a false panel is hung.

After installing and connecting the dishwasher, a test should be performed. If the connection is successful, the dishwasher is ready for use.

Z. Y. We have it connected to an ordinary socket with a grounding, from a sister in a multi-storey building to a simple outlet. as far as I know, everything is plugged into an outlet, just like a washing machine

Although I have a new house, and the wiring is good with grounding, I still called the foreman and installed a special socket for the car. Dishwasher not a lot of e-mail. It takes energy, but in the event of an electrical interruption, the machine gun will fly out first, and only then the car. Considering the cost of repairing the dishwasher (or even have to buy a new one), I decided not to save on installation.

If the house is 30 years old. No electrical warranties whatsoever. There may be voltage fluctuations, surges, etc. In a rented apartment you do not want to do anything, and the owners may be unhappy. Honestly, I don’t know what to recommend. If possible, allocate a separate outlet for the car, maybe you need to take a pilot-type extension cord in order to at least slightly protect yourself and the car.

It is necessary to invite an electrician and he will advise the best option for your apartment (we are not advisers in this, we need professional advice, since electrical safety must be 100%).
In my opinion, it is advisable to connect to an outlet without an extension cord, or in extreme cases through a filter (as for a computer) with a fuse, so that the thickness of the extension cord is not less than the thickness of the dishwasher cord.

Here are the promised photos (not very good quality, because I took pictures with my phone)

Z. Y. I remembered that the electrician told me about the extension cord when he installed the split system, since there was not enough to reach the outlet. And a separate outlet is needed for the dishwasher, for the washing machine, for the split system, for the microwave.

Request to everyone !!
My question is not about the machine itself, but about how you have it connected. The fact is that we have a rented apartment, the house is 30 years old. old pipes, really want a car. but, I understand that most likely this is impossible, but still I want to ask you to take a picture of how she joins the pipes with you, and suddenly everything is not as scary as it seems to me.

The surest way. Warn the owners about your desire to buy and install a dishwasher, invite an installer from the official service for servicing the future machine. The service must provide a guarantee for the correct connection. If something happens (tfu tfu) no claims to you personally. Let the owners figure out the service themselves. Of course, these will be additional costs, but no nerves.

Come on, you scare the person. A dishwasher is much safer than a washing machine. There is a little more water in it than in a kettle, so the danger of flooding neighbors from behind old pipes is minimal. Moreover, almost all dishwashers with aqua stop. Most of the electricity is consumed when heating water, and since there is little water, heating does not last long. Therefore, the old wiring is not so bad. Of course, you should not plug into a very poor outlet, but there is also nothing to bother too much.

[Right]

Right. But if in doubt, it is better to "overdo it than not do it" Therefore, the advice of an electrician is needed.
Our house is 40 years old (adobe under a brick), 10 years ago the wiring and pipes were changed. All large equipment is connected, as I said, simply to the sockets: washing machine, dishwasher, split system, microwave (microwave + convection + grill + steamer). It just costs a good machine for an electric meter.

[Lenusya]

Thanks to all!!
Well I say, I just need to find out how it is all fastened, and the rest is not a problem))) the owners do not care.
My washing machine is connected to an ordinary outlet, the voltage does not change - it just knocks out if 2 bread machines, a pressure cooker, a multicooker and a washing machine, 2 TV sets or 2 computers are turned on, and suddenly someone wants to have a microwave - that's when the switch just flies out. And so, everything is normal. The entrance and exit - for water at the washing machine was done by a former tenant, so we didn't even have to strain, but I worry about the pipes - because when they wanted to change the tap, my husband simply could not unscrew it - more precisely, the water was shut off, I was afraid to break everything so there is no movement at all , and if a miracle suddenly happens and it will be decided to buy a car, it is natural that the master will connect, and I will only use it when I'm at home, and we don't leave the washing machine unattended.

Lenusya
THANKS FOR THE PHOTO !!! I'll see how unas have it all plugged in and whether it is possible to insert an adapter there. Past tenants did something there - they improved the plumbing, so to speak, as much as possible.

Svetochka, and we have a dishwasher connected in general in the bathroom. And you look, at times, how does it all hold up ?! But no, everything works fine

[SkoNaNi]

I already thought about the bath and there is the same garbage .. pipes .. I already thought that there. and even a small one)) in short, the matter at the moment is for a small one - to persuade my husband .. otherwise I promised not to buy anything else .. he certainly did not believe me .. but does not agree yet))) But the water wears away the stone ... I just need to be sure that it can be connected with us, and before paying the person who comes and see how it is possible to do it, I just want to find out how realistic it is with me. That's the whole gap))) But I basically figured it out, it remains to sweep the stone)))

For us, it was the master from the company who did it. So he cut a tee right under the kitchen sink. That is, water is taken from a flexible hose that goes from the bathroom cabinet to the kitchen sink.

In an old apartment (the house was about 50 years old!) They made a socket for the washing machine outside the bathroom, there was not enough cable from the car, so the electrician advised us to buy a powerful pilot. And connect only the car to it. And so they did, for almost 4 years that we lived there - there were no problems. Washed at night - everything is fine. So any problem can be solved.

[lira70]

Come on, you scare the person. A dishwasher is much safer than a washing machine.
Therefore, the old wiring is not so bad. Of course, you should not plug into a very poor outlet, but there is also nothing to bother too much.

Grounding is required. For the first 3-4 days I was connected to a simple outlet. An infection fought when the dishes were shifted from the sink and inadvertently touched the metal, and he was there all around .. Then they powered up from the wiring to the electric stove and put a separate outlet
lira70

but I'm worried about the pipes - because when they wanted to change the tap, my husband simply could not unscrew it - more precisely, the water was shut off, I was afraid to break it so everything there does not lend itself to movement at all,

I understand that the valve in the riser does not shut off the water. All pipes and valves in the riser must be repaired by the housing office free of charge. If anything goes there it is their fault and concern. My grandmothers and my houses are 23 and 25 years old, respectively (there is one housing office on the same street). They also decided to change the taps in the bathrooms and the water was not cut off. I called the locksmiths, though they spent some time, but after my call to the technician-caretaker, everything was quickly changed for free.
The water to my dishwasher (bay) is connected under the sink in the kitchen like this

regular tee. On the right, a pipe from the riser fits, at the bottom there is a fill in the washer (there is its own inlet valve and pre-filter, it was attached to the dishwasher), on the left is the connection to the tap in the sink.
The drain is connected through a special tee insert, which is located immediately after the siphon from the sink. Sold in any household store or construction market. Can be purchased separately, or with a siphon. Both tees cost a penny.

Good day.
I thought about purchasing a dishwasher. I can only put it in the kitchen.The problem is that in my kitchen I already have a washing machine connected and the dishwasher can be placed from the sink at a distance of 1 m 80 cm, that is, the hoses will need to be lengthened.
I am still planning to connect the dishwasher on my own, because I am going to make repairs soon and it is not advisable to call the master now.
Please tell us in more detail how to connect the dishwasher to the water supply and, if possible, post a photo.
I would like to sort this out as soon as possible - soon our hot water will be turned off ...

I think that it is necessary where the washer is connected to the water, instead of the "double", put a tee and screw both the dishwasher and the washer there. Do the same with the drain. This will probably be the easiest way. As for the lengthening of the hoses, there will be no problems with the drain, but with the filler ........... if the machine is equipped with an aquastop function, it will not be very easy to lengthen the hose (there is a special hose). So it may be more convenient to change places of the washer and dishwasher. Moreover, the dishwasher must be next to the sink, otherwise it will be very inconvenient.

Unfortunately, there is no way to change the dishwasher and the washing machine in some places, since my washing machine is 60 cm. The place along the wall for the dishwasher is only 45 cm. And the inlet hose will most likely be with an aquastop. I'm very interested in how you can lengthen it?
I read the whole topic, but I'm interested in the combined connection of both washing and dishwashers, as well as lengthening the hoses.

Connect, of course, through a tee. And I doubt that the hose with aquastop can be lengthened. The drain hose from the washing machine is precisely lengthened. Specials for sale. hoses and the master rearranges.
it may be easier to connect another pipe to the required distance through the tee under the sink, and put a tee pipe-dishwasher-washing machine on this pipe. also lengthen the sewer through the tee (by the way, we have lengthened the sewer to the dishwasher just like that)

Many thanks to Lenus for the answer and for the photos ... An excellent solution. I think I will do something similar at home ...
And at the expense of the hose with aquastop, can it be sold somewhere of a different length (after all, the inlet hose is screwed on or is it cast with a machine)? Or will you have to buy a dishwasher without an aquastop? (I hope there are some). Although I really liked the model with aquastop ...

I have a washer with aquastop, I had to replace the inlet hose with a regular one, but long. The length of the hose was not enough. It is a pity, but did not dare to increase.
The drain was built up elementary. We bought an adapter for hoses on the market. It is plastic, the hose is put on on one side, and the extension hose on the other. For reliability, the husband fastened with "clamps". Everything is going well.

It cannot be screwed with aquastop. But it's better for you to look at the store.
I'll take my old dishwasher to the dacha in a week, and then I can see and tell you how it is attached there. But it's better for you to look at the store yourself.

julia2411
any hose can be extended. Regardless of whether it is with or without aquastop. It does not change anything. You need to measure the diameter of your hose, preferably in inches, and go to a good plumbing store. There, the sellers will pick up any nozzles for you to extend the hose. You can do this with garden hose extensions too, but they are not as reliable as I think.
To lengthen the hose, you will need to buy a piece of hose of the required length (preferably with a small margin), a special metal sleeve that will fit the hoses tightly on both sides, and two clamps that will tighten the hose around this sleeve.
It's like one of the options. I am sure that the store will offer you others.

The hose with the aquastop can be lengthened, only then the aquastop will not completely block the water. And if so, why pay more for an unnecessary feature?

[julia2411]

julia2411
It is not necessary to lengthen the hose with the aquastop itself; you need to lengthen the water supply to it from the riser.This can be done using a "flexible hose" - a hose in a metal braid, sold in construction markets of any length. There should be nuts at both ends. On the one hand, we screw such a hose onto a tee (wiring per pm and cm), on the other hand we screw in a small piece of pipe of a suitable diameter with a thread on both sides (used to connect pipes), and on this piece we screw a hose with an aquastop.

And I extended it with a metal-plastic pipe, brought it along the base of the kitchen cabinets and fixed the tap on the wall, everything works as it should :) Electrolux ESF 2440 installed it on the kitchen cabinet, calmly 6 sets of dishes fit into it, but with a baking sheet and a large frying pan there are already problems ... I will probably put a narrow full-size one.

Especially for my compatriot I pulled quotes from ixbt:

The owner, I am very economical, the Kaiser said, I will save you 2 kopecks a month on electricity, you just connect me to hot water ... but for this savings I will eat 3kg for 150r of salt per month ...
pour a tablespoon of ordinary salt into 2 cups and pour into one of cold water in another glass of water g 60, and stir ... see how quickly the salt dissolves and where ...
horror of course, disconnect the water from the mountains ...
if connecting the mountains of water would be economically profitable, then the Germans would have provided such an opportunity long ago on bosk, simene and chalk ...

- PMM is connected to hot water through a gas water heater;
5. The most incomprehensible thing - after washing, the dishes are mostly wet (all in drops of water).

rkos, the main problem is washing with hot water. Hence poor drying and water droplets on the dishes. As a rule, dishes are dried due to the temperature difference - in your case, it is always hot there.

1. Connecting the PMM (at least Electrolux ESL 46010) to hot water leads to the fact that after washing some dishes will not be dry enough, and some are just wet. The reason is that drying takes place due to the temperature difference, which will not exist in this connection option. The instructions say that it is not recommended to connect to hot water due to the reduction in the program runtime. Not a word about the deterioration in drying quality. This, in my opinion, is a clear flaw of the manufacturer, he is obliged to warn about such things. By the way, the reduction in washing time is somehow not noticeable.

"About connecting PMM to hot water., I saw the results.
Many times I have heard customers' questions about whether it is possible to connect a washing machine or dishwasher to hot water. And there is nothing to answer. Somehow it is impossible, but why ... there is nothing to justify. But yesterday I had a chance to make a dishwasher, which was connected to hot water and so it worked for a little over two years.
So I'm telling you.
As a result of the fact that hot water is constantly flowing through the valve, the valve began to close poorly, hum when closing and the closing process itself took about 30 seconds with a loud roar. The valve had to be changed. But that was not the main reason for the call. Called due to error '30 - pallet leak. And the leak is everywhere. Due to the fact that the entire inlet side is hot, almost all hoses, when filled, become soft like jelly and some connections simply do not hold pressure. One hose generally weakened and flew off the branch pipe, despite the fact that there are notches on the branch pipe.
According to the client's story, the machine never washed well. All glasses after several sinks become dull, with a white coating. On the face of the wrong operation of the rinse, that is, in general, the lack of its work. They use tablets, and the tablets react exactly to the temperature, and it turns out that the substances do not dissolve at the right time and when they have to. In general, all this time there was no sense from the dishwasher and now it is almost ditched, and only because it was connected to hot water. "

there has been a discussion about hot water many times, if you are interested in detail - a search will help. but in short, if - then this is not a very necessary business.it is necessary that the water is not hotter than 60 degrees, the drying will be worse, if you turn off the hot water, you will have to wash it with your hands in a cold one, you will partially save on electricity and it will be better to wash on short programs, but there will be no delicate wash. but there are situations when these disadvantages are not important, for example, if the water is heated by a gas column. if you decide to connect to hot water, then it is better to take an AEG with a turbo dryer, since condensation drying (due to the temperature difference) will work poorly or not at all.

In fact, there are many machines for which a connection to hot water is permissible, but this should be clearly written in the instructions!

In the murzilka, the opposite is written to mine: you cannot connect to hot water or through any instantaneous water heaters

Especially for my compatriot I pulled quotes from ixbt:

Thank you for taking care of fellow countrymen. I have a regular Ariston. When I took it, I clarified the connection issue, since there was a renovation in the kitchen and all the wiring was changing. Since the answer was yes, then the connection was made from hot water. I have hot water from the water heater, so while there is gas, there is hot water. It dries as I wrote - everything is fine. In the end, you can, after all, turn off the column, and draw cold water, but through the column

[connecting PMM to hot water]

Hello everyone! I read about connecting PMM to hot water and I had a question: why bother with this connection at all? How much of that electricity is needed to heat water? And further. No one thought about why the Extra Rinse program runs in the washing machine with cold water? I also rinsed in cool water during hand washing (in Soviet times). And if there are water meters and the price of hot water is 5 times more than cold water, and if you want to wash the dishes at night, when the cost of electricity is 5 times lower than during the day, the question of saving will disappear by itself. But this is just my personal opinion, since respected members of the forum live in different places and in different conditions. I just really wanted to talk.

Hello everyone! Recently I became the owner of PMM Veko 6830. Now my life is divided into 2 parts: before PMM and after.
I couldn't find where to write about setting up the rinse aid, so I'm writing here. The instructions say: "The rinse aid indicator turns on and the rinse aid indicator appears on the display in ON or OFF format.
You can change the status of the ON or OFF indicator with the Start / Stop / Cancel button. If you turn off the machine with the On / Off button when ON, the rinse aid level indicator will turn on when the level of the rinse aid in your machine drops during operation. turn on the machine with the on / off button in the OFF state, the rinse aid level indicator will never light up ".
Translate, please, who understood what this is about.

There is one nuance here - hot water contains many additives to save pipes from corrosion, they are not very harmless for cars, so most manufacturers are against this. It's another matter if your hot water comes from heating cold in any of the autonomous heaters (water heater, boiler, etc.), then yes, especially if you have a gas water heater, there can be savings. After all, we don't have a lot of gas meters.

[required by me]

I will answer from personal experience!
A year of washing in the dishwasher - everything is in order. A year later, my husband changed something under the sink, and I notice that the dishes were not the same after washing in the PMM. I am silent in a rag, I'm afraid to say too much to my husband that another required by me the equipment does not hold in my hands for a long time, everything breaks down (well, you won't believe how many broke down in those months). In general, I am silent. After 3 weeks, they turn off our hot water for preventive maintenance, I, like a decent one, go to close the entrance valve to the apartment and live normally until the evening. In the evening I load the dishwasher, turn it on ... and wiggle the dishwasher does not work.Thoughts are rapidly flashing in my head, what to say to my husband, now there will be another tirade, I was silent for 3 weeks, I waited everything, I had to ring the bells right away ... and everything like that. I made up my mind to call my husband ... It turned out that he mistakenly mixed up the hoses and connected the dishwasher to the hot water. Here ... I don’t remember exactly what I didn’t like in the dishes after hot water, not dirty - this is definitely, but not like that, more than a year has already passed, it’s hard to remember, but it was clearly not so clean - then I read in the instructions that it is impossible.

Well, the main thing is everything is whole. but if he passed this through a filter for drinking water (hot, that is), then they would have gotten a replacement: (I have one friend who wanted to drink tea for free, the filter flew, at first they offered to replace it with a new one, for 10 tons. r., but somehow I changed the filter elements for him and by 2.5 tons he only got it, although it's all the same, it's a shame :)

A week ago I bought SIEMENS SN25M280EU.
We have a private house, a well, a double-circuit boiler. That is, the quality of hot water does not differ from cold water.
That's all I think: if the water in my dishwasher is not purely cold (and we have it downhole, that is, it is very cold, even after the hydraulic tank), and after an additional mixer of hot and cold water, degrees on average 35C - 40C, then, in theory, current consumption should be reduced, well, and the total time for the trash. After all, you will not have to heat from 15C ...
Convince me not to do this ...

[Kapet]

Kapet You just need it, we talked about the shoddy quality of hot water in the central water supply. Considering that gas heating of water is cheaper than electric, in any case, in Russia it is so, God himself ordered you to connect warm water to the tap. Another thing is that Siemens often advertises a reverse heat exchanger in its machines, when the hot water being discharged is cooled by the supplied cold water, in this case it will work less efficiently, but this is not an indicator.

[Kapet]

Kapet With warmed water, it will wash faster IMHO, although in principle without a tangible difference. Water in modern PMM is heated by a direct-flow heater. And he heats up water absolutely nothing 12-16 liters and in Siemens-bosch it is even less.
I have a pace. incoming water in winter 3-4 * C, lux washes without problems

Yes, but the figure of 1 kW for one wash scares me a little ...

[Kapet]

Kapet If your gas is cheaper, then it is worth heating up. 1 kWh in St. Petersburg 2.55 rubles

Yes, plus all the charms of the private sector, including a significant voltage drop in the 220V network (in the "best" years in winter, up to 130V). A clear stump that you need to take another stabilizer - with a decent voltage drop, especially in winter, the losses on such a stabilizer increase ...

[Kapet]

By the way, for the private sector and if there are problems with the power of the electrical connection, it will be more profitable to connect warm water, otherwise the direct-flow heater will greatly drain the load from Kapet... A purely household stabilizer will not help you, in theory, here you need to put something like your own transformer mini-substation, but I will not say how much it will cost now and it seems that this permission is needed. If we manage to establish this, then the problems with the drawdown will be largely solved. And so, I repeat once again, connection to hot water is much more profitable for you.

something like your own transformer mini-substation, but I will not say how much it will cost now and it seems that you need permission for this.

it will be very expensive and a big hassle to issue a permit, my father did this for his friends last year, a lot of paperwork had to be done.

[Kapet]

Kapet, sorry, but your question for me looks something like this: "I bought myself a brand new Mers, nicho, if I fill it with kerosene and pour it into Oleina's crankcase? ..."
A machine under 6 thousand hryvnias, one tablet of 3 hryvnias, even with a powder, the sink will pull hryvnias by one and a half at the cost price, and you are bothered by 26 kopecks per kilowatt? Yes, with some tweaks, you can bring this amount up to 13 kopecks. Super! For the sake of such savings, it is worth turning a blind eye to poor drying!

[Kapet]

Kapet I didn't think at all. Drying will definitely be worse, you have drying due to the difference in pace. cold water and hot dishes, and not like in Electrolux ...

"... and he threw some logs into the dying fire of conversation ..."

A friend in Syktyvkar (of disgusting quality and cold and hot water in the taps) is going to connect the PMM to a reverse osmosis filter (it seems "Atol"). Places an additional storage tank after the filter (so that the PMM does not wait for the next portion of water). Long chose PMM designed for minimum water pressure.

It seems that he is not going to give up pills affecting hardness.
The main thing is that the water for the PMM will go almost at room temperature.

[Kapet]

Kapet, sorry, but your question for me looks something like this: "I bought myself a brand new Mers, nicho, if I fill it with kerosene and pour it into Oleina's crankcase? ..."

Yes, with some tweaks, you can bring this amount up to 13 kopecks. Super! For the sake of such savings, it is worth turning a blind eye to poor drying!

In fact, globally, the question looks a little different. Not even at all like that. It's not about saving at all.

Our house is not a new building, the network wiring inside and out leaves much to be desired. In the cold period, the mains voltage sags down the street quite noticeably, which cannot but affect the speed of heating water with a dishwasher. And this already, you see, cannot but affect the quality of the dishwasher. Fot and fsё ...

Well, take it and reconnect it to hot water in winter and cold water again in summer.

Well, take it and reconnect it to hot water in winter and cold water again in summer.

Unfortunately, not everything is so simple.
Hot water from a double-circuit boiler, if anyone knows, is an unpredictable thing, both in terms of the rate of appearance and temperature. Therefore, there is no point in reprogramming the dishwasher for hot water due to the unpredictability of the washing quality due to the xs-what temperature of the water from the boiler. The idea was to put warm water into the hose from a special mixer. But, as they probably correctly say here, the quality of drying will deteriorate.
I went thinking for a long time ...

In fact, globally, the question looks a little different. Not even at all like that. It's not about saving

Once again I apologize for my, so to speak, irony. The machine's flow-through heater will heat up to 50 degrees 3 liters of water in a couple of minutes, even with 100 volts of voltage in the network. The problem is different: the control board may be unstable, once (who knows, what is its lower limit ...). Secondly, the pump and drain pump will most likely operate at reduced power, and hence the decrease in the quality of washing is unambiguous. But why can't an ordinary household stabilizer for a couple of kilowatts be able to solve the problem? Well, or more powerful (if funds are available), immediately for the whole house. IMHO, the normal way out.

Is he seriously going? In general, such filters, if not taken with a pressure-increasing pump, clean 5-6 l / h. The water is distilled. There are also pills to it ... Let's calculate the cost of this game, a set of filters for Atoll (I give the price for state ones) 3 thousand rubles, more precisely 500 rubles an annual replacement of pre-treatment filters and for the 5th year, three thousand, as I said, and no less 8 thousand for a reverse osmosis system, but this is without a pump, there will not be enough water for the car or you will have to pause washing dishes for an hour and a half, you will have to take it with a pump and an enlarged tank, if I don’t confuse 15 thousand. It reminds me of how I first bought a Danon amplifier from a friend on the cheap, but then I almost had to take acoustics for 90 thousand :)

Secondly, the pump and drain pump will most likely operate at reduced power, and hence the decrease in the quality of washing is unambiguous. But why can't an ordinary household stabilizer for a couple of kilowatts be able to solve the problem? Well, or more powerful (if funds are available), immediately for the whole house. IMHO, the normal way out.

It may not work unstable, but simply die due to voltage drops, but actually a 3 kW stabilizer is not that expensive. In short, you will have to buy a car and a new house :)

Is he seriously going? In general, such filters, if not taken with a pressure-increasing pump, clean 5-6 l / h. The water is distilled. There are also pills to it ... Let's calculate the cost of this game, a set of filters for Atoll (I give the price for state ones) 3 thousand rubles, more precisely 500 rubles an annual replacement of pre-treatment filters and for the 5th year, three thousand, as I said, and no less 8 thousand for a reverse osmosis system, but this is without a pump, there is not enough such water for the car or you will have to pause washing dishes for an hour and a half, you will have to take it with a pump and an enlarged tank, if I don’t confuse 15 thousand. ...

I just installed reverse osmosis for myself and I will say that this amount is enough for a dishwasher, it does not immediately consume 14-16 liters, but gradually - I got a full tank in 0.5 hours. So - the person thinks correctly and let him connect it like that - it will be cheaper than buying a new dishwasher later.
