Rilong experts suggest: Precautions for pipeline installation and use.

Common quality problems in indoor water and electricity decoration

1, pipe installation must find a professional mechanic. No matter how luxurious and upscale your decoration is, it's not worth it if you don't want to spend money on it. Often the sudden cracking or leakage of the pipeline will cause the loss of the price of the water pipe itself by dozens, hundreds or even thousands of times.

2. After installation, pressure test must be carried out. The pressurization test is generally carried out under the condition of 1.5 times of water pressure, and there should be no water leakage during the test.

3, under the condition of no pressure test method:

1) Close the main water valve. (that is, the water pipe switch in front of the water meter)

2) Turn on the faucet in the room for 20 minutes, and then turn off all the faucets after ensuring that there is no dripping.

3) Turn off the water inlet switch of toilet water tank, washing machine and other equipment with water storage function.

4) Open the main water valve.

5) After opening the main valve for 20 minutes, check whether the water meter moves, including moving slowly. If there is any movement, it is leaking. If you don't move, you'll be fine.

4. In daily use, if the following conditions are found, check the relevant pipelines as soon as possible:

1) The surface of the wall paint is moldy and blistered.

2) The baseboard or wooden floor is black and bubbles appear on the surface.

12 problems to be considered in water pipe installation;

(1) Waterway design should first consider all water-related equipment, such as water purifier, water heater, kitchen treasure, toilet, wash basin, etc., their positions, installation methods and whether hot water is needed;

(two) use gas or electric water heaters in advance to avoid temporary replacement of water heaters, resulting in repeated transformation of waterways;

(3) In addition to sockets such as washbasin, toilet, washing machine, etc., it is best to take one from the bathroom to facilitate mopping the floor after receiving water; It depends on the owner's preference.

(4) After the location of the washing machine is determined, the drainage pipe of the washing machine can be considered in the wall, which is beautiful and convenient;

(5) There should be a suppression test after the waterway renovation, but now many decoration teams have not suppressed the test. They will lie to you in many ways, saying that there is no need to suppress, saying that the water pipe is under pressure and so on.

(6) It is best to have the owner present for the inhibition test, which can play a supervisory role; Because some decoration teams will cheat the owners in this link. The method is: when pressing, open the "return valve" of the pressing pump to form a loop. Although the press pump seems to be working, the pressure in the pipeline is not great, especially the electric press pump, which students should pay more attention to. If you don't understand, ask a professional to take a look at it for you.

(7) When closing the house, pay attention to check whether the drains in the kitchen and bathroom are unobstructed. If the drainage is slow, the property should be dredged in time; Protect the drain when decorating, especially when laying kitchen and bathroom tiles, which is most likely to cause cement to fall into the drain and cause blockage;

(8) After the kitchen and bathroom floor tiles are laid, check whether the floor drain is unobstructed (the drainage speed after removing the floor drain cover shall prevail, because most deep-water sealed floor drains have the problem of slow drainage);

(9) If the redundant floor drain is to be closed, the gap between the drain pipe and the floor drain must be blocked to prevent water from overflowing;

(10) When sealing the floor drain in deep water, it should be cleaned frequently according to the use situation, otherwise the rubber pad under the floor drain will not be sealed after hanging dirty things;

(1 1) Another point is particularly important. It is best not to use deep water to seal the floor drain of washing machine. The washing machine drains water quickly and has a large displacement. The launching speed of deep-water sealed floor drain can not be reached at all, which will directly lead to water overflow.

(12) In the process of waterway reconstruction, four points should be paid attention to in the cold and hot water supply pipes reserved for later installation of electric water heaters and faucets:

1, and ensure the distance 15 cm (at present, the distance between hot and cold water of most electric water heaters and faucets is 15 cm, and some are10cm);

2, hot and cold water nozzle height is consistent;

3. The cold and hot water nozzles are vertical to the wall surface, and care should be taken not to let the bricklayer get crooked when sticking the wall tiles in the future (if they are not vertical, it will be difficult to install them in the future);

4, cold and hot water nozzle should be two centimeters higher than the wall, in the wall brick, also should ask bricklayer to ensure that the wall brick and water pipe nozzle are in the same level. If the size is not suitable, after installing electric water heaters, faucets, etc. It is likely that you need to purchase additional connectors such as pipe clamps and internal wires to complete the installation of water pipes. Under normal circumstances, take the ceiling water pipe and the floor water pipe. However, I still suggest that you choose "up but not down, down but not up, up and not down". Because digging is not allowed, and digging will destroy the waterproof, and once the water leaks, it is not easy to find it, because the water flows downwards, and the leaking place does not necessarily flow out first. Only when the water leaks downstairs or the water overflows Jinshan will the water leak be found, but because it is a concealed pipe, it is impossible to find the leaking place immediately, so the loss will be considerable; If it is on the top, the kitchen and bathroom can be hung with aluminum gusset plates, and you can walk along the corner when you go through the wall and pass the entrance, and you can also wrap it with plaster lines without affecting the appearance. When the water pipe leads from the top to the bathroom, when water is needed, the vertical groove should be opened down to a suitable height and a water outlet should be reserved. The advantage of this is that once the water leaks, because the water flows downwards, the leaking place can be found immediately, which is convenient for maintenance.

Waterway installation is the comparison of walking pipes on the ground, wall and top.

1, the pipeline on the ground-the pipeline is the easiest to install, and there are not many materials, but if there is water leakage, it is not easy to find, the maintenance is the most troublesome and may cause heavy losses (such as soaking the floor and damaging the cabinet of the neighbor downstairs), and the installation will destroy the waterproof of the ground!

2, the pipeline on the wall-pipeline installation is difficult, with the least materials. In case of water leakage, it is easy to maintain and find water leakage, so it is generally not easy to cause heavy losses! However, slotting is more difficult, which will cause more damage to the wall. Will not destroy the waterproof property of the ground!

3. Pipe top installation-Pipe installation is the most difficult and requires a lot of materials. In case of water leakage, the maintenance is convenient, and it is easy to find that water leakage is not easy to cause heavy losses! Will not damage the ground waterproof! The lobby should have a ceiling (in some cases, if there is no ceiling, the wall can be slotted horizontally)

At present, the installation is mainly over the top of the wall and horizontal grooving. If required or unconditional, construction workers who do not install on the ground will also install from the ground! In short, the industry advocates floor installation!

Some suggestions after waterway installation

1, the pipeline should be fixed-it should be fixed with a professional pipe clamp, and nails must not be used to prevent damage to the water pipe and reduce the service life.

2. Keep the hot and cold water connected after the pipeline installation, so as to prevent the hot water pipeline from being damaged by the later construction and not being found in time-decoration will cause great losses.

3. Test the water flow during installation to prevent the pipeline from being blocked during installation and reduce the water flow.

4, powder wall should pay attention to keep the spacing of the air outlet and the vertical and height of the wall.

5, pipeline should pay attention to protection, in order to prevent damage by heavy objects (especially in low temperature season).

6. Never apply environmentally unfriendly waterproof materials such as modified asphalt directly to pipelines-it will cause serious water pollution!

7. Remember not to install the faucet immediately after installation. Be sure to open the plug first to let the water out, so as not to block the faucet with dirty things and cause unnecessary trouble!
