Common problem

Small faucets are related to all aspects of home decoration. Here, we will review the installation methods of faucets in different places of the home. As well as the faucet series problems that netizens often encounter, we hope to bring convenience and ease to everyone's home decoration.

Installation knowledge of No.1 faucet

Prepare the installation tools, and check whether the supporting parts are complete before installation. Common faucet parts include: hose, rubber washer, shower, water drain, knee, decorative cap, etc.

1. Installation of single hole basin faucet

When purchasing a single handle basin faucet, you should pay attention to the diameter of the water outlet. Most of the water in the market is hard pipe water inlet, so you should pay attention to the height of the water outlet, which is the most appropriate 35 work minutes from the basin down. During installation, a special angle valve must be selected, and the angle valve must be fixed with the cold and hot water pipes from the wall. When you find that there is a distance between the angle valve and the faucet water supply pipe, you can buy a special extension pipe to connect it. Remember, do not use other water pipes to connect, because if the water pressure is high, it is easy to fall off, leak, and cause loss to you. If the inlet pipe is too long and exceeds the outlet pipe, the part can be cut off according to your needs. If the angle is inappropriate, it can be bent to the position you need. Remember: Do not bend hard to 90 degrees or more. When installing the basin to drain water, please do not forget to purchase the small connector of the faucet (the faucet is short circuited). Don't forget to flush the water pipes buried in the wall in advance before you install them.

2. Installation of shower and bathtub faucet (wall hanging)

After you purchase shower, bathtub and wall faucet, you can select the appropriate height of buried outlet pipe. The distance between hot and cold water pipes must reach 15cm. Before installation, you must not forget to flush the water pipe to avoid damage to the faucet due to high water quality.

Concealed shower and bathtub faucets: After purchasing concealed faucets, the valve core of the faucet should be embedded in the wall. Pay attention to the thickness of the toilet wall before embedding. If the wall is too thin, the valve core cannot be embedded. The plastic protective cover of the valve core shall not be removed easily during embedding to avoid damage to the valve core caused by cement and other sundries during embedding. In addition, pay attention to the up, down, left and right directions of the valve core when embedding the valve core, so as to avoid the wrong embedding of the valve core. When embedding the water inlet pipe of the wall mounted faucet, if the size has deviation, the adjustable crutch can be used for calibration.

3. Installation of thermostatic tap

Before installing the thermostatic faucet, please check whether the water pipe is hot on the left and cold on the right. Be sure not to connect the hot and cold water pipes wrongly to prevent the faucet from working normally. Gas and solar water heaters cannot use thermostatic faucets because the water pressure is too low. Please do not forget to install the cold and hot water filter screen when installing the thermostatic faucet.

4. Installation of single hole kitchen tap

It is required to be stable, because kitchen faucets are used frequently, and they are easily loosened when being moved around, so the lock nuts must be tightened. At present, there are some faucets on the market that are fixed by the screw tube with enlarged nuts. This stabilization effect is very good. If the problem of water removal and lifting can be solved, it will be a popular trend in the future.


Summary of common problems of NO.2 faucet and solutions

1. Question: How high is the water pressure when the tap is used?

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

2. Question: What are the common tap valve cores in the market? Which has a long service life?

Answer: There are three common tap valve cores: stainless steel ball valve, ceramic disc valve core and roller valve core.

Stainless steel tap valve core: it is a tap valve core with high scientific and technological content at present. Some high-end sanitary brands use irregular seven hole steel ball valve core processed by laser technology as the valve core 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 of regulating the warm water, which can accurately control the water temperature, ensure the rapid and accurate outflow of hot water, and save resources as much as possible.

Ceramic tap valve core: it is the most common valve core. Its advantages are low price and less pollution to water quality. However, due to the brittle ceramic texture, it is easy to crack.

Spindle type tap valve core: the advantages are smooth rotation of the handle, easy and simple operation, comfortable and easy feel, aging resistance and wear resistance.

3. Ask: What should I do if the faucet at home leaks?

Answer: Most people think that the faucet leakage is the problem of the valve element. In fact, as long as it is used properly, the valve element is not easy to have problems. Therefore, if the faucet leaks, it should be analyzed from its essence.

(1) The tap still runs out of water after the valve element is closed. This phenomenon may be caused by the loosening of the pressure cap, which causes the valve core to become loose and cannot seal water. The solution is to take down the handle and decorative cover and tighten the pressure cap again. Another possibility is that the rubber ring at the bottom of the valve core is deformed and cannot seal water. The solution is to take out the valve core, check the rubber ring at the bottom, reset it and reinstall it.

(2) Water seeps from around the spool. This phenomenon may be caused by loosening or displacement of the valve core. The solution is to take out the valve core and reinstall it

(3) Water seeps from the middle of the valve core. This phenomenon is caused by the damage of the valve core. The solution is to replace the valve core. If the faucet leaks, replace the valve core, which will increase the maintenance cost.

(4) Water leaks from the bottom of the tap. This phenomenon is generally caused by the O-ring of the water inlet pipe is not installed or deformed. The solution is to screw out the hose. If the O-ring is not deformed, the O-ring and the water inlet pipe can be installed again. If the O-ring is deformed, replace the O-ring.
