Piping in the bathroom: diagram and installation principle

Piping in the bathroom involves not only laying water supply and sewerage, but in some cases even heating (in private houses). This is not an easy matter and requires certain theoretical knowledge and practical skills. If the latter can be mastered in the course of the work, as they say, by trial and error, then the theory is a little different. In this article, together with the website, we will provide all the necessary theoretical knowledge that will help you properly route the pipes in the bathroom.

Piping in the bathroom: piping layout

The piping layout in the bathroom remains unchanged in all situations - the pipe laying location, system components, but in no case the diagram, may change. The focus is on the main pipeline, from which branches go off to connect consumers. As a rule, almost all plumbing fixtures require cold and hot water for their operation, as well as a channel for draining the waste liquid. Consequently, the laying of pipes in the bathroom involves the installation of three main channels: cold and hot water supply and sewerage.

All of these pipes are usually laid next to each other, although they may have different connection points. If we are talking about an apartment with a centralized supply of cold and hot water, then all these highways originate in approximately one place - as a rule, risers are mounted in a special niche of a bathroom or a bathroom.

The situation is a little different in apartments, in which hot water is supplied by means of. Here, the hot water supply pipeline originates directly from the heating unit, which can be both a storage and a gas water heater or a double-circuit heating boiler. If you delve into the theory, then the difference between the distribution of pipes for centralized and individual water supply (drainage) lies in the direction of the flow of water through the highways. Outwardly, everything looks almost identical.

Correct piping in the bathroom: diameter matters

Many have noticed that when two water consumers work at the same time, the pressure in them decreases sharply. This is due to a lack of pressure and an insufficient volume of water supplied to the distribution system. Simply put, this happens in cases where the water supply is assembled with pipes of the same diameter.

This effect is not observed in apartments with central cold and hot water supply. But if only cold water supply is used, and hot water is heated locally, then the lack of pressure is already causing some inconvenience.

For example, you are taking a shower, and at this time the water supply to the washing machine turns on. The following happens - the pressure in the heating device drops (less water passes through it), and the water heats up more. Instead of the set 50˚C, boiling water begins to flow into your shower head. Agree, it's not very pleasant.

So, you can get rid of this unpleasant effect only by using pipes of the correct diameter. In this regard, the installation of pipes in the bathroom is as follows. Lines are laid with ¾ "pipes, and plumbing outlets are ½" in diameter. It should be understood that the greater the analysis of water in the house, the thicker the pipes will have to be used - this rule applies to private houses. For apartments, everything costs with the above diameters.

Hidden or open pipe routing: what to choose

There are two ways to solve the question of how to lay pipes in the bathroom - this is an open and a hidden method. When approached from an aesthetic point of view, of course the hidden pipeline is better. But it must meet some requirements.

If we talk about open piping, then it does not represent anything good - this method of laying is used in order to save money, which is achieved by reducing the cost of purchasing high-quality material and reducing the amount of work done. After such installation, you get a not very good appearance of the room and constantly condensing pipes in the cold season.

Materials accompanying piping in the bathroom

If you think that in order to resolve the issue of how to run pipes in the bathroom, it is enough to purchase elements of one or another plumbing system, you are mistaken - a full-fledged sewage and water supply system provides for the use of a fairly large number of all kinds of plumbing products. First of all, these are shut-off valves. In the internal wiring, two types of shut-off valves are used - ball valves, which are installed at the water inlet to a house or apartment, and instrument ones, the purpose of which is to control each individual water consumer.

In addition, in the piping in the bathroom, it is used, the installation of which is not allowed without the use of a check valve and a mechanical water filter. The filter contributes to the full performance of the meter for a long time, and the check valve is installed at the request of the water utility and does not allow unscrupulous citizens to unwind it.

How is the installation of pipes in the bathroom

In some cases, a pressure reducer can be installed at the water inlet to the house. Many consumers, such as storage water heaters or modern heating boilers, cannot stand the prolonged exposure to high water pressure, which usually appears at night when the water drawdown is significantly reduced. It is the reducer that allows you to stabilize the water pressure in the internal wiring and extend the service life of expensive units.

In conclusion, I want to note that the piping in the bathroom must be carried out in accordance with the requirements for the installation of a certain pipeline system. What does it mean? For example, one of the requirements for installing the sewerage wiring is the presence of a slope towards the drain. Or if we are talking about a polypropylene plumbing, then this is maintaining the pipe soldering regime. In general, you need to learn a lot of information - without it, there can be no question of installing a high-quality water supply system.
