Summary of common problems of faucet and solutions

1. Question: When the water pressure of the faucet is used, the water pressure is high?
Answer: The pressure of tap water is generally 3-5 kg, which is about 0.3-0.5MPa. If the pressure exceeds 6 kg, it is considered to be relatively high, and people will feel uncomfortable when using the faucet normally; if it is less than 3 kg, the water pressure is generally considered low.

2. Question: What are the common faucet spools on the market? Which ones have long service life?
Answer: There are three common faucet valve cores: stainless steel ball valves, ceramic disc valve cores and roller roller valve cores.

Stainless steel faucet spool: It is a faucet spool with high technological content at present. Some high-end sanitary ware brands use irregular seven-hole steel ball spools processed by laser technology as the spools of their latest faucet products. The steel ball valve core is particularly suitable for areas with poor water quality, because it is not affected by impurities in the water and will not shorten its service life. Moreover, the handle of the steel ball valve core has a relatively large angle in the area where the warm water is adjusted, which can accurately control the water temperature, ensure that the hot water flows out quickly and accurately, and save resources as much as possible.
Ceramic disc faucet valve core: It is the most common valve core. Its advantages are low price and less pollution to water quality, but due to the brittle ceramic texture, it is easy to break.
Shaft-rolling faucet spool: The advantages are smooth handle rotation, easy and simple operation, comfortable and easy feel, aging resistance and wear resistance.

3. Question: What should I do if the tap at home is leaking?
Answer: Most people think that the faucet leakage is a problem with the spool. In fact, as long as it is used properly, the spool is not prone to problems. Therefore, if the faucet is leaking, it should be analyzed from its essence.
(1) The faucet still emits water after the valve core is closed. This phenomenon may be caused by the loosening of the pressure cap causing the spool to become loose and unable to seal the water. The solution is to remove the handle and decorative cover and tighten the pressure cap again. Another possibility is that the rubber ring at the bottom of the spool is deformed. Can not seal the water, the solution is to take out the valve core, check the bottom rubber ring, reset it and reinstall it.
(2) Water seeps from around the valve core. This phenomenon may be that the spool is loose or displaced. The solution is to remove the spool and install it again.
(3) Water seeps from the middle part of the valve core. This phenomenon is that the valve core is damaged. The solution is to replace the valve core. If the faucet leaks, replace the valve core, which will inevitably increase maintenance costs.
(4) Water leaks from the bottom of the faucet. This phenomenon is generally caused by the O-ring of the water inlet pipe not being installed or deformed. The solution is to unscrew the hose. If the O-ring is not deformed, re-fit the O-ring and the water inlet pipe. Yes, if you find that the O-ring has been deformed, replace the O-ring.
