Piping in the bathroom

Repair in the bathroom or installation of plumbing equipment is associated with the organization of plumbing communications. Actions include laying new or replacing old products. Proper piping in the bathroom is necessary for long-term operation and uninterrupted operation of the plumbing system.

Charting

Installation work begins with the selection of the necessary materials and tools. To choose them correctly, you need to plan the number of highways, determine their location and identify connection points.

Creating a wiring diagram is the initial stage in creating functional and working communications.

The connection type is divided into the following options:

• connection to the centralized sewerage. Installed in apartments or private houses;
• organization of an autonomous station. It is mounted in suburban real estate if there is a private well on the site.

In the first option, the planned water supply system is adapted to the existing water supply parameters.

To get a working and efficient scheme, when planning the connection of the trunk to the central station, it is necessary to take into account such points:

• select a piping scheme. Distinguish between collector or serial piping;
• determine the method of laying products - hidden or external. The choice of method depends on the location of plumbing or household appliances;
• identify all points from which water will be taken;
• perform the calculation of the necessary materials, parts and determine. Additional elements include: adapters, meters, valves, valves, fittings, coarse and light water filters. At this stage, methods for connecting and docking products are chosen;
• plan emergency taps, gate valves to build a solid and safe system.

When organizing, it is necessary to follow the listed factors.

In addition to them, the following points are added:

• the maximum load that will be placed on the water supply is calculated, taking into account the parameters of the equipment that will be located in the bathroom;
• for buildings with 2 or more floors, it is necessary to distribute water throughout the network. Calculations are carried out along the vertical water column.

At this stage, decide how hot water will be supplied. Taking into account all the data, the designer prepares a drawing of the future scheme. It should display all the important points in detail.

It should be marked with hot lines in red, cold lines in blue, the amount of materials needed and their type, as well as connection points.

Which sewer pipes to choose

When choosing pipes, they are guided by established standards, study the material for strength and other performance qualities. It is also necessary to pay attention to the complexity of installation and the purchase of additional parts for them.

The most popular and allowed options include:

Polypropylene

They are used when installing new networks or replacing old ones. Withstand high pressure inside the sewer system. Among them are products designed for hot and cold water supply.

Pipes for hot water can be recognized by their appearance, they have a layer of fiberglass or foil. The elements are connected using fittings.

Their advantages include a long service life, affordable cost, a large assortment, low thermal conductivity and resistance to aggressive environments. The disadvantages are temperature restrictions when wiring a hot main (75 degrees - constant, 90 - short-term), difficulty in replacing structural parts.

Copper

They are reliable and have high performance characteristics. They are used infrequently, since they are expensive, complex connecting elements are required for their installation.

When installed, you can count on a long service life (up to 60 years), high elasticity, even in freezing conditions, resistance to temperatures from -100 to 250 degrees.

metal-plastic

They have a convenient fastening with the help of crimp fittings. They are recommended to be used only for outdoor installation and for cold mains, as a high pressure surge may cause rupture of the connections.

The advantages of metal-plastic products include reasonable cost, simple installation, and the possibility of bending. The disadvantages are the high price of connecting parts, short service life (up to 15 years), painstaking care (every 2 years, the joints should be checked and additional tightening should be performed).

Steel

Today they are not used, because they are difficult to install, require grounding, and are subject to corrosion.

Cast iron

They are not as susceptible to corrosion as steel. They are used for risers and laying external networks. The disadvantages include a large weight of products, the need for a strong bond.

Waste sticking occurs inside the pipe, which leads to a decrease in the throughput of the network.

When choosing, their size and diameter are important. The selection is carried out using a special table of correspondence between the diameter of products and throughput.

The minimum dimensions include the following indicators:

• for a network from plumbing fixtures to a riser, products must have a diameter of 5 to 10 cm;
• for risers - from 10 to 11 cm;
• for pipes that transfer waste to a septic tank or a centralized main, the diameter of the structure must be larger than the last product leading out of the house.

For a multi-storey building, such parameters are not suitable; pipes with a large diameter should be used.

Ways

The choice of a tee (serial) or collector method of piping depends on the technical conditions of the room. The serial scheme is used for small or medium-sized rooms, with a small network length.

At the same time, there are a small number of points of consumption in the bathroom, which are located at a short distance from each other.

The connection is made to one water riser, followed by the connection of all household and plumbing devices. Tees are installed at the places where the water branches to the places of consumption.

The advantages of such a system include low material costs, simple installation and the absence of complex calculations when drawing up a circuit.

Of the minuses, they note a low set when the devices are turned on at the same time, damage to products due to pressure drops in them, the installation of separate water shut-off valves, a violation of the entire system if the main pipe breaks.

The collector circuit is used when there are a large number of appliances in the bathroom. The principle of the system is to install a distribution structure (comb) that directs water into separate lines. This method allows you to ensure a uniform load throughout the highway.

When connecting a collector circuit, it is necessary to find the optimal place for its placement, taking into account the number of connection points and the branching of networks in the bathroom. It contains two separate systems for cold and hot water.

The following advantages of such a scheme are distinguished:

• system reliability due to a small number of connections;
• permanent work, in the event of a breakdown, a separate line is simply turned off;
• the number of devices included does not affect the pressure level.

Important! Installation of such a system requires a professional approach due to more complex design and installation.

Examples

Each master carries out the work in his own way, based on the classic schemes for piping. The stages of installation and their duration depends on the area of ​​​​the room and the tasks.

For example, when distributing pipes from the drive through the bathroom to the kitchen, the following work is performed:

• a pipe rises from the tank to the ceiling and, using bends, is led to the kitchen through the walls;
• the tee is located at the location of the bathroom. A sink and a toilet bowl are connected through it, a faucet is installed at each end;
• the hose from the mixer is attached to the pipe using special combined connections;
• in the kitchen, the pipe is installed in the place where the sink is planned. With the help of a tee, you can prepare an outlet for a washing machine or dishwasher.

These actions can be done independently, without resorting to the help of professionals. Hot water supply is mounted in parallel with the cold one, using flax, fum-tape or other sealing materials at the junctions.

Piping in a polypropylene bathroom begins with shutting off the water in the room. With a centralized water supply system, they first take up the taps of the risers.

Then a ball valve is installed to shut off the water, a filter and meters, separately for hot and cold water. Next, the wiring is carried out to the toilet, bathroom and kitchen, taking into account the sequence of rooms and appliances.

Important! For the installation of polypropylene pipes, it is necessary to perform welding work. To do this, you need to measure the product of the required size, clean its ends and coupling.

Insert them into the soldering iron and heat the tool. On average, after 5-8 seconds, you can start working. The heating time depends on the diameter of the pipe and the device itself. Next, the parts are removed and pressed against each other.

Within 4 seconds, it is possible to correct the bumps, while scrolling the elements is impossible. The parts are allowed to cool, 30 seconds is enough for this. When piping, additional valves should be installed to control the flow of water in the kitchen, bathroom and toilet.

At the final stage, the connection points are checked. To do this, open all the valves and watch the pipes, they must hide in the walls. After that, you can perform finishing work.

Hidden wiring

A high-quality water supply system should be not only functional, but also invisible to others. This is especially true for small rooms where the sewer and water supply network is hidden on the floor and walls behind ceramic tiles or behind a false ceiling.

Work for organizing a hidden system is carried out in several stages. If this is a replacement of products, then to begin with, the old products are dismantled.

As a hidden water supply, polypropylene pipes are most often used. Their installation is associated with careful soldering of parts.

Important! Metal-plastic structures are not recommended for use due to their short service life and possible emergencies.

Installation begins with determining the dimensions of plumbing. Correct measurements allow you to avoid mistakes when organizing exits from the walls of the corners. Then the walls are shtrobovka, depth, taking into account the optimal placement of pipes.

How to do it right

After drawing a sketch, a method for arranging the network is chosen. There are two types:

• open when all communications are outside. Of the pluses, they note easy installation, of the minuses - an unaesthetic appearance;

When choosing a wiring method (collector or serial), the following points should be taken into account: strive to reduce the number of bends and connecting nodes, avoid overlapping hot and cold lines.

Regardless of the open or hidden method of locating networks, the work is carried out in the following sequence:

• installation of a control valve;
• installation of a coarse filter for central water supply in order to improve water quality;

With proper piping, there are no problems with the operation of plumbing equipment.

To avoid mistakes, you need to consider the following points:

• carefully study the connection technology of the materials used;
• it is obligatory to carry out normalization of pressure when connecting in series. To do this, pipes with a large diameter are mounted at the connection point;
• install emergency cranes in important areas of the network;
• to ensure proper system tightness and reliability, minimize the use of flexible hoses.

The quality of the work performed depends on how comfortable living in the house will be.

Cost of work

At first glance, the organization of the plumbing system in the bathroom is understandable and accessible to many, especially the open way. During work, a layman may encounter difficulties. There are organizations that perform piping in the bathroom.

The price of work depends on the type used, the number of points:

Also, the price can be set based on installation at one point and the materials used:
