How to properly piping in the bathroom?

When repairing, combining or remodeling a bathroom and a bathroom (SU), it sometimes becomes necessary to replace communications or lay them along a new route in order to optimally position old or new sinks, a toilet bowl and the bathing container itself. So, let's take a look at how to piping in the bathroom in order.

Starting with design

It is necessary to fully think over and design a new plan, having developed such a layout of the room as to link all the elements into a single and effective system. This is especially true of water pipes and sewerage in the bathroom. Design should be carried out based on your own wishes and features of the room.

If the control room is separate, usually only a sink or toilet is installed, for example, as when wiring plumbing in a bathroom in Khrushchev. With a joint SU, the scale of work is completely different, so we will consider this particular case.

Mounting methods: open and hidden

There are only two ways to carry out plumbing and sewerage in the bathroom - open and closed (hidden). They have a number of features, which we will discuss below. Read more about the layout of water supply pipes.

Open piping is a method in which all connecting elements are outside, that is, visible.

Installation is done very quickly, but you should not expect special aesthetics. Many people try to lay communications near the floor, but parallels sticking out under their feet (even tinted) can ruin any interior. But it is very easy to eliminate the leak or rearrange something again.

Concealed installation

Hidden piping in the bathroom, the photo of which is given below, is a method that involves laying pipes in wall strobes or pouring them with mortar when leveling (raising the level) of the floor.

This method is more time consuming, but all pipes are hidden. But it is necessary to do everything correctly and reliably. Otherwise (during a leak), you will have to hammer a tile or other coating and wall.

Important! If the riser is located near a load-bearing wall, it is strictly forbidden to hammer strobes in it.

Laying schemes

With any installation method, it is necessary to develop a scheme and choose a physical installation method. There are only three methods:

• Sequential way (ordinary) . Applied everywhere. The elements are connected one after the other. It is considered the best and optimal option. But there is a drawback - the pressure of the liquid in all devices is not the same, since closer to the riser the pressure is greater.
• collector option . It involves the implementation for each device of a separate section for the supply and removal of liquid or feces.

The advantage is a uniform pressure in all elements of the circuit and in each device. The disadvantage is the overspending of materials. Here is what the correct piping in the bathroom looks like:

Here you can see that all appliances (sink, bathtub, toilet) are connected to a water supply with a separate shut-off valve in case of leakage and possible repairs, and each component has its own separate drain. But such a scheme is too expensive. In the budget version, they cost less material. The optimal solution is 2 plumbing (cold and hot water) and one sewer pipe.

• With pass-through elements . This option is used only in industries where it is necessary to carry out water supply and drain systems through walls. These couplings and passage elements are almost never used in everyday life:

Ways to hide protruding elements

Open installation is simple and economical, but so that its use is not at the expense of aesthetics, it is worth paying attention to methods of how to hide the components of an open system. The following photo shows two ways to hide - tile and build a cabinet around the pipe:

You can close the hard-hitting parts with a plastic or wooden box, install a decorative false panel or attach home-made curved wire hangers to it and paint the visible part under a tree trunk, and paste over the wall with washable wallpaper.

At the very beginning of work, the main water valve is always installed at the riser, which (in the event of an accident) can immediately block the main water artery. It is advisable to insert a filter into the system after it. This is done in areas where the water is dirty (with impurities, sand).

If there is a high pressure in the system, it is necessary to purchase a reducer with an appropriate pressure gauge. Following its readings, set the pressure that is optimal for your system (about 4 atm). Purchase a return filter so that the reading does not go astray when the pressure is at its lowest.

Important! Do not wind a lot of tow or tape - modern plumbing parts can burst, because many of them have very thin walls.

Buy adapters, fittings, nuts and other parts made of brass or steel with thick walls only.

With a serial connection of all components of water and sewer communications, one pipe is carried along the perimeter. A tee or cross is placed (for example, if a “washer” is supposed to be) where an outlet to the device (washbasin, bath) is needed.

Do-it-yourself piping in the bathroom with polypropylene allows you to weld the squares into the main water channel.

This is the cheapest option. But it is desirable to provide separate additional taps that block each water artery near the corresponding devices. This will allow you to repair or replace any of them without shutting down the system for a long time.

For a complete do-it-yourself piping in the bathroom with polypropylene or metal, so that each device has the same pressure, you must use a manifold. Available with 2, 3, 4 outlets. Can be combined if there is a need for more holes.

Piping: copper, plastic, metal-plastic

In Soviet times, all communications were steel and cast iron. But today copper, plastic and metal-plastic options have come into fashion. Let's consider each separately:

• Copper piping in the bathroom is certainly good, but many plumbers do not recommend this option. At the point of connection to a metal riser, galvanization may occur - copper will quickly oxidize. Many fats can come into contact with copper - this affects the throughput. In addition, copper connections generally need to be soldered. There are pipes with threaded or flanged connections, but they are very expensive and available to few.
• The layout of plastic pipes in the bathroom is carried out mainly using two materials - polyvinyl chloride and polypropylene. The first is only suitable for sewerage and cold water connections. Hot liquid can warp them. Plumbing parts for draining are made from this material: tees, elbows (90, 235 degrees) and so on. The piping in the polypropylene bathroom is used in the plumbing system for liquids of any temperature. They are made with thick walls, so they are able to withstand hot water. They are marked with blue and red longitudinal stripes.
• The best wiring is metal-plastic. Aluminum foil is laid between two layers of plastic, so the pipes can be used for any purpose. But they are expensive, so they are mainly used in heating systems.

On the following video you can get acquainted with the design of the compact manifold assembly:

When laying copper or plastic pipes in the bathroom, it is necessary to properly plan all the work, think over the connection diagram, calculate and purchase all the connecting parts in order to work quickly and efficiently. The choice of installation method must be made based on the characteristics of the premises and financial capabilities.
