Mixing hot water with cold Neighbors, it's time to make repairs right
As the mixer wears, the plates may rise in relation to each other, forming a gap, in which case, a squeezing effect may occur.
Another device that can be the cause of the squeezing phenomenon is a bidet (hygienic shower) with a mixer and an additional button on the shower head that closes the water without shutting off both taps.
The valve must be fixed under the tank, after the shut-off valves. The drain hole must remain free.
The most common reason for the presence of hot water instead of cold water is the effect of squeezing hot water with cold water due to the fact that the pressure of hot water (6 atm.) In the water supply system at home is greater than the pressure of cold water (4 atm.), And there is no check valve. In multi-storey buildings, cold water and hot water supply systems supply water to apartments in different ways.
Usually, mixing occurs in all apartments along the riser, and its source (cause) is in one of the apartments of the same riser.
What to do if hot water runs out of a cold water tap
If water does not flow, then your faucets are not defective and are not the cause of mixing. Otherwise, the defective mixer or part will have to be replaced.
When switching from gander to shower and back, the balance is rarely maintained, since this switch is rarely of high quality (I mean that the switch holes are made asymmetrically). And it is possible that something also got into the switch (see above about the tap).
It will take a long time to explain why this happens, and the pictures will not help much here, because cartridges are a rather thin and delicate thing, just take my word for it. And yet, the cheaper the mixer, the less reliable its cartridge. I hope this truth also does not need proof.
When performing repair work, housing and communal services with mistakes made when changing the riser and during assembly, they incorrectly connected the wiring of the water temperature flow.
At the end of hygiene procedures, many people forget to close the valves and only release the button - this is enough for the liquid to stop running.
Perhaps the reader has encountered a problem when boiling water spits out of all taps. Moreover, boiling water is also poured into the toilet bowl. Very annoying water problem. This may occur due to improper installation of pipes inside the apartment
However, in the vast majority of cases, the reasons lie in the neighbors.
It is important to add here that the higher the floor, the stronger the influence of this factor, because it is easier for water to flow down than to rise up. However, the absence of non-return valves in at least one apartment on the riser can be a potential cause of water contamination.
However, the higher the floor is located, on which there are no check valves, the greater the risk of water squeezing.
A plastic riser has a lot of advantages compared to a metal one:
- a light weight;
- resistance to corrosion;
- the impossibility of deposits on the inner walls;
- long service life (up to 50 years).
When a gasket rots inside the mixer, the correct water supply may be disrupted throughout the riser. There is also a type of faucet that has a water switch for a faucet and a shower. Due to the fact that it is possible to switch different water temperatures, there may be confusion with the water from the neighbors in the riser.
If cold water flows from a hot water tap, the first thing to do is to understand the causes of what is happening and eliminate them without waiting for the consequences. Boiling water in a cold line is not only discomfort, it can lead to a number of problems:
- failure of the cold water meter;
- damage to plastic pipelines;
- violation of the mechanism of the drain tank;
- failure of household appliances designed to supply cold water.
Of course, the first thing you need to do is call the housing office (however, now the name of the management company may be different) and call a plumber. However, as correspondence with readers shows, it is not always possible for plumbers to quickly find and eliminate the cause themselves. After reading this article, you yourself will be able to at least a little understand the reasons for such a misunderstanding and even contribute to its elimination.
It is also worth noting that the reason for the periodic appearance of heated water in the pipes of cold water supply can be not only your own system, neighbors are often to blame. This is the specifics of the water supply of an apartment building - improperly connected plumbing in one apartment can become a source of headache for residents of the whole entrance.
As a rule, the pressure in the SHW, due to the characteristics of the systems, is initially slightly higher than in the SHW. If, during operation, cold water pipes become clogged faster than hot water pipes (and this is usually the case), then the pressure difference becomes significant.
Non-return valve is an element of protective fittings that prevents a change in the direction of the medium flow. It must be present in every apartment. Its installation is carried out at the cold riser outlet. It is desirable that the DHW riser is also equipped with such a riser.
Mixing cold water into hot why
If it is not in the system, then if one of the mixers on the riser fails, hot water can simply transfer cold water, and therefore only boiling water will come out of the tap.
To give the correct answer to the question you need to watch the video. After viewing, you do not need to seek help from specialists. Detailed instructions will help you solve your problems. Happy viewing.
It makes sense to check the operation of the shut-off valves on the roof and in the basement, if there is a basic knowledge of plumbing work. Another solution is to close the two main valves and check them for water retention. It is necessary to turn the cold water valve and immediately open a similar tap. With the correct operation of this shut-off valve, cold water should flow from the tap.
It is not uncommon for situations in which water heating occurs spontaneously, for no apparent reason, then, in addition to checking your system, it is worth talking with your neighbors to find out if they have a similar phenomenon. If the same situation is observed in all apartments of the entrance, but no one can name the reason, you cannot do without a master.
The situation is similar with water heating equipment. In the absence of a check valve, the heated water will go into the cold water pipeline, as a result of which the pressure in the system will be broken, and the boiler itself may fail.
It is necessary to feel the pipe with cold water that goes to the apartment. It is necessary to touch it in the place of the valve that shuts off the water for the entire apartment. If the pipe is hot, then the problem is outside and you need to call the UK.
The design of modern shower models provides for the presence of 3 locking elements: two are designed for hot water and cold water, and the third is a button located on the shower head, with which you can fix the selected mode.
If the gasket rots in it, then this is fraught with a violation of the water supply. Hot water blocks access to the cold tap.
In the summer, hot water is often turned off to carry out repair work, so many people purchase boilers and use them until the centralized supply of hot coolant is turned on. Some people forget to turn off the valve, and the boiler works in parallel with the central water supply system, which causes hot water to appear in a cold tap.
The pressure in the DHW pipe is 6 kg / cm, cold water - 4 kg / cm.Due to improper connection or use of household or plumbing fixtures, hot water under pressure begins to displace cold water from the riser.
If the tap is not closed, i.e. point No. 1 is not fulfilled, then not only you, but also your neighbors in the riser will use hot water from your boiler, for the production of which, moreover, electricity was spent. Such cases were reported to the Board of the HOA by residents of the 1st. 3rd, 7th, 8th, 11th and 12th entrances.
A similar situation can occur with a traditional faucet with 2 taps and a shower. The cause of the problem will be the switch, which is located in the middle of the body and with which the water is redirected to the shower. The standard scheme of its operation is such that when turning all the way in one direction, the water goes into the taps, and when turning in the other, respectively, into the shower.
Another situation is possible - the owner of the apartment himself recently made changes to the configuration of the pipelines of his apartment, changed pipes, installed new plumbing. The cause of the malfunction may be his actions. Before calling the masters, it is worth going through the system, checking the correctness of the joints, in case of an error, take measures to correct the situation.
The need to install check valves
If no liquid comes out of it, then the plumbing fixture is working. If it appears, the device is faulty and needs to be replaced.
At Avangardnaya, hot water ended along with the heating season Utilities say that the water cools down even on the way to the m..
Most often, consumers use a single-lever mixer. Refers to the cartridge type. The main working part has 3 openings for supplying cold, hot water and draining mixed water. Mixing of water is carried out by overlapping the holes for cold and hot water by the required amount with the mutual movement of two ceramic plates, adjustable by a handle.
What should I do if hot water comes out instead of cold? What is the right thing to do and what measures should be taken in the first place to prevent the risk of such cases in the future, save yourself from unnecessary cash costs and unnecessary trouble?
THE PROBLEM OF WATER MIXING IN APARTMENTS Pavlino 65
If the hygienic shower mixer remains open, i.e. point number 5 is not fulfilled, cold water will be mixed into hot water through your open hygienic shower mixer and vice versa. In this case, mixing will continue until the specified mixer is closed.
In general, in a ceramic faucet box, the balance of water temperature is generally regulated by a fairly short turn of the flywheel (faucet handle). In your case, as a result of some kind of malfunction, this lack of a ceramic faucet simply got worse.
During the summer months, systematic preventive work is carried out in relation to hot water pipes. The whole house is without hot water for about three weeks. This practice is necessary to ensure that there are no major accidents.
Residents of multi-storey buildings rarely think about how the water supply system works. The desire to delve into this issue arises only in the event of serious interruptions in the supply of water. Unfortunately, this happens quite often.
