When carrying out repairs in an apartment, we change not only furniture, floors, wallpaper, ceiling, but also outdated plumbing. The plumbing scheme in the apartment is a system of technical products and water pipes that connects various plumbing devices in different places of the apartment.

There are two main schemes for supplying water to an apartment:

• Tee (serial);
• Collector.

Trikikovaya water supply

The tee wiring of the water supply in the apartment is carried out in the form of a series connection by pipes of consumer points (bath, toilet, taps, washing machine, etc.) with a common riser. First of all, the main pipes for hot and cold water are connected, and then further branches are made from these pipes using tees for the needs of apartment consumers. The advantages of such a scheme are low price, the most compact option, installation is simple and convenient.

The disadvantages of the tee-type wiring diagram for water supply pipes include the following: pressure drop with several included consumption points; in the event of a leak at one of the consumption points, the entire system has to be turned off; placing tees in a relatively small area is difficult.

In the event of repair work, it is possible not to turn off the water, if a tap is installed in front of the plumbing at the points of consumption, shutting off the water supply for a specific consumer.

Such a layout of the water supply system is the best option for a small apartment, and a collector circuit is suitable for a larger apartment.

Collector wiring of water supply

Collector wiring of water supply is carried out according to the scheme of supplying pipes to each individual point. Every object, be it a shower, toilet, dishwasher or tap, receives a given volume of water, even if these points are turned on at the same time.

The collector, located at the inlet of the water conduit to the apartment, is made with conclusions, the number of which is equal to or slightly exceeds the number of served consumption points. A larger number of conclusions is understandable, this is necessary, for example, when buying another washing machine or you need to install an additional tap in the kitchen - then these conclusions will come in handy.

Let's list the advantages of the collector wiring of water supply:

1. Convenient location of taps, they are usually installed in a separate place reserved for plumbing equipment.

2. Turning off, for example, a shower will not affect the operation of other bathrooms.

3. There is always a stable pressure in the circuit, you will not lose hot water in the kitchen when you fill the bath with the same water.

4. The repair is convenient and easy to carry out, because there is only one pipe from the point of consumption to the collector.

5. Even if you open all hot water taps at once, the water temperature will not drop even by a degree.

Not without its drawbacks, and this layout of the water supply system in the apartment. For its installation, a lot of materials are needed; such a number of pipes requires adequate financial costs. It takes a lot of time to perform this numerous wiring efficiently.

Replacement of water supply wiring

To replace the water supply in the apartment, you first need to dismantle the old water supply. First of all, we turn off the risers of the water supply system, then we cut off the old pipes from the valves with a grinder and unscrew them, trying not to make distortions.

How to replace pipes in the bathroom can be seen in the video.

Almost always, the section of the water supply to the valve is clogged with a mixture of sand and slag. Be sure to clean the pipe before starting installation, usually using a string or screwdriver. We change valves and filters. When installing polypropylene pipes, we make an external chamfer at the cut, clean the pipe and insert one side into the fitting, and the other into the nozzle. Then, using a soldering iron, we melt the plastic, install the end of the pipe into the fitting and wait a few seconds. That's it, the operation is over - let's move on to the next connection.

Water supply in a private house

At present, it is impossible to imagine a private house without a modern water supply system and it does not matter if it is an expensive mansion or a very small summer cottage. The wiring diagram for the water supply of a private house is carried out according to the same principle as the wiring of the water supply in the apartment. The two methods are exactly the same - sequential and parallel. The sequential method is the most optimal for connecting a water supply system in a small house. This is the same tee connection method, where the pressure in the system drops as the number of consumers increases. This method of wiring a water supply system in a private house is still the simplest and cheapest.

The parallel method is nothing more than a collector method, all the same essence, where consumers are each connected separately to a common supply and there is no pressure and temperature drop. But this method of laying the water supply system in the house remains the same costly and long in terms of execution time.

But there are still differences and the first distinguishing feature will be the source of water supply. In this case, it is a well or a well. Further, the presence of a pumping station or pump is required. To accumulate water and create a certain pressure, a hydraulic accumulator is needed so that there are no contaminants, a filter is used for cleaning.

Further, according to the water supply wiring diagram in a private house, you need to put a tee after the accumulator, and the tee should have shut-off valves with two outputs - one for the house, the other for the water supply to the garden. The filter is, of course, placed on the outlet for the house.

After the filter, another tee is inserted into the water supply system, which will allow the separation of cold and hot water. The next step is to connect the cold supply pipe to the cold water manifold, and this manifold must have shut-off valves at each individual outlet. The hot water pipe must be connected to a heating boiler or gas boiler, and then to a manifold supplying hot water to the water supply.

Perhaps there is no need to remind that the best thing for this system is to carry out the distribution of water with polypropylene pipes. This is the simplest and most inexpensive type of such connections.

For normal operation of the sewerage and water supply piping, the following requirements must be met: without fail, after each washing and dishwasher, urinal, bathtub, sink and sink, install siphons of water locks. In showers and toilets, this odor trap is located in the body itself.

Obviously, there is nothing difficult in installing a water supply system for a private house or apartment, but still it is better to let professionals do this business.
