What is the reason for the decrease of tap water?
The general problem is that the filter screen at the faucet outlet is blocked by sand. Find a tool (or by hand) to remove the filter screen of the faucet, then remove the filter screen and rinse it with water from the back, or remove the sand with a toothpick and install the filter screen. Turn on the tap to see if the water output is large. The small sand grains in the picture are normal, and the main pipeline will appear more after each maintenance.
The above are the most common reasons, but there are other reasons, such as insufficient water pressure or the valve not being opened in place, which will reduce the water output of the faucet. However, you can check out such problems. If the water pressure is not enough, you can check the faucets in other parts of your home first. If the other party's water output is normal, it means that the water pressure is fine. There is also the problem of the eight-character valve (angle valve). The eight-character valve will be installed under the vegetable basin and washbasin at home. Because the spool of the eight-character valve is made of porcelain, it can only be opened or closed at 90 degrees. If you touch the valve cover when you take things or mop the floor, you will turn the valve cover down if you are not careful, resulting in a decrease in water output. Remember that the eight-character valve opens to the left and closes to the right.
How to fix the faucet if it is closed or dripping?
The dripping situation can be divided into many situations, and different situations will have different repair methods. Let's take a look at the specific introduction:
1. If the axial washer inside the faucet is worn after long-term use, the faucet may not be closed tightly and the water outlet may leak. During maintenance, the gland bolt can be rotated with the tool holder and replaced with a new axial gasket.
2. If the triangular gasket in the faucet gland is worn after long-term use, it may also lead to water leakage in the gap at the lower part of the faucet, so maintenance is actually the same as changing the axial gasket.
3. If the nut is loose and the faucet is not tightly closed, resulting in water leakage at the joint, a new nut or a new U-shaped washer should be replaced.
