Hello, may I ask, the door of the main valve of the tap water is right, is the anti theft door good

According to the second paragraph of Article 47 of the Sichuan Provincial Water Supply Regulations, no unit or individual has the right to operate the main water valve.

According to the eighth paragraph of Article 57 of the Sichuan Provincial Water Supply Regulations, anyone who operates a public water valve without authorization shall be fined 100 yuan to 300 yuan.

The details of the water supply regulations vary from place to place, but they will never allow users to operate the public water valves themselves.

When you close the valve again, you can report directly to the local water company for repair, and at the same time report the person who closed the valve.

Of course, if the valve is within your unit or community, such as a general meter for the entire unit or community, but the valve only cares about your building or a unit, it is not the water company's business. You can cut the pipe behind his watch in the middle of the night... If he has no water, he won't clog the sewer, and he won't close the valve.

Yes. Some of the water remains in the main valve to the water outlet.

If you want to drain the water at the main water completely, first turn off the main valve of my mains, turn on the faucet at the outlet, and wait a few seconds for the water to drain the water in the pipe.

If a household faucet bursts, it can be repaired in the following ways:

Turn off the main water valve.

2.Use a 250-30mm adjustable wrench or pipe wrench to rotate the old faucet in a counterclockwise direction to remove it.

3.Go to the plumbing equipment (or hardware) store to buy a faucet with the same specifications (this faucet generally has two specifications: 15mm and 20mm, you should be 15mm) and raw material belt.

4.Hold the faucet with your left hand and wrap the thread of the faucet with the raw material tape in a clockwise direction for a few turns (this is very important, the direction of the raw material belt must be wound clockwise, and the raw material belt will leak if it is wound in reverse, that is to say, the direction of the raw material belt should be opposite to the direction of the faucet thread).

5.Tighten the faucet clockwise onto the connector of the water pipe and tighten it with a wrench.

6.Open the main water valve.

Even if it is an anti-theft door, anti-theft, fireproof, waterproof and anti-people, you don't have to be afraid, believe that science is true, if you don't worry about sticking a picture door!

This is an "air valve", which is hard sealed, and it is not recommended to use it, and it is easy to leak. Change the shut-off valve of the PPR. This interface is not hot-melt, the two ends of the valve body can be twisted open with a wrench, and it is screw and gasket sealed.

Looking at your picture, it is estimated that you don't need to dismantle the old valve, just add a PPR stop valve between the old valve and the water meter, but you have to look at the scene.
