How to connect the boiler to the water supply?

network During the preventive shutdown of hot water in summer, it is difficult to imagine life without a hinged water heater. In addition, it is simply necessary in apartments where regular water shut-off occurs, and in dachas where there is no hot water supply system. The most widely used electric water heaters of flow type, it is about them that will be discussed in the article. However, it is not enough to buy a boiler, it is important to know how to connect a boiler to a water pipe. Let us consider all the subtleties of this process.

Installation of the

The big plus of an electric instantaneous water heater is its easy installation. Virtually any person can mount the device and connect it to a network and a water pipe.

Install a boiler of this type can be almost anywhere, because the outlet, as a rule, is throughout the apartment, and hold a hose with water is not difficult.

Important! It is advisable to mount the device only on a supporting wall, located near the bathroom and the kitchen, so that hot water enters both rooms. However, you can meet and built in the walls of water heaters - for this you must first hollow out a niche in the wall.

After you have determined the location, you can start connecting the boiler. To do this, you only need a puncher, two anchor bolts and a wrench to screw them:

1. Pre-measure the distance between the lugs of the boiler, drill two holes for the anchor on the wall.

Important! If you mount the device on a tile, it is advisable to get into the seam, otherwise - use a special drill for tile.

1. Insert the anchor bolts and secure the mount inside the holes.
2. After this, you can hang the boiler on the wall.

Important! Ensure that the safety device is snug to the surface and bolted firmly. In order to ascertain the smoothness of the installation, you can use the building level.

Wiring diagram for the water heater to the water supply

Connecting the boiler to the water pipe is slightly different at the very beginning:

• If you install the water heater on iron or copper pipes, you will need to cut a T-piece. It is desirable to install it along the central axis of the water pipe, while the vertical part should go directly to the water heater.
• In the case of polypropylene pipes, the process is a bit more complicated. You will need to make an incision on the pipe and solder special tees. This is easiest to do with the help of a repair coupling - American. They are attached to the extension pipes, to which the MPH coupler must be fixed.

This is the difference between the preliminary preparation and the completion. Further the scheme of connection of a boiler to a waterpipe is no different:

1. In order to find the shortest path from the water heater to the water supply system, you can use a regular construction plumb line. Connect it to one of the two chimneys of the boiler and measure the distance.
2. Shut off the water supply in the room by means of a safety valve for cold and hot water.
3. Horizontal water supply pipe cut with a bulgaria or pipe cutter. It is best to pre-install a water tank that is left in the pipe.
4. Prepare the cutting site. If it is a metal pipe, cut the threads, just cut the edges for the polypropylene pipe.
5. Install the tee according to the instructions given above.
6. Screw the shut-off valve into the tee, and install a polymer or metal tube on it, or a flexible piping. A metal-plastic or polymer pipe of ½ inch is perfect.
7. Install the drain valve that comes with the appliance to the external water inlet of the water heater. It is necessary to drain water and eliminate excessive pressure.
8. On the drain valve, install a back-pressure relief valve, without which you can not start the water heater. It always comes complete with a device and has a thread on both sides.
9. Connect the boiler to the water supply system. The outlet connection( hot water) is connected to the isolation valve by means of a pipe or a hose, and the cold water hose is connected to the back-safety valve.
10. After installation, it is possible to include water in the house, but it is important to pre-close the water heater valve.

Important! If the drainage pipes are built into the wall behind the tile, then flexible liner can be used. However, you still have to cut the pipe and install the tee.

Why is a back-pressure relief valve necessary?

Almost always this device comes with the boiler itself, because without it the device can start to work incorrectly. It has two ends, both of which have internal and external threads. The diameter of the valve is 15 mm. As it was mentioned earlier, at one end it winds up on the inlet pipe of the boiler, the second one - to the sewerage system, to the flexible piping or the withdrawn pipes.

It performs three important functions:

• Do not allow water to go in the opposite direction, which can cause a strong leak and pipe integrity;
• Prevents water pressure jumps directly in the tank of the water heater;
• Discharges water into the sewer system at increased pressure.

Connecting to the

network It is very important to make the first connection of the device to the network only after you have finished connecting the boiler to the water pipe. In addition, it is necessary to wait until the water completely fills the entire tank.

Important! As a rule, it takes only a couple of minutes if all steps have been performed correctly, and normal pressure in the water supply pipes. Otherwise, the heater, located in the tank of the boiler, will become unusable and, most likely, will not be subject to repair.

Helpful Hints:

1. When buying a water heater, make sure that the cord is equipped with a fuse system. If it is not, then from the purchase of this device should be discarded.
2. Pay attention to the status of the outlet in which you plan to connect the boiler. It must be reliable and have a water protection system in the form of a plastic cover from above.

As you can see, the process of installing the storage electric water heater is not at all complicated. Great help can be provided by video on how to connect the boiler to the water pipe, in which you can visually see the whole algorithm of installation.
