Common sense of cabinet hardware maintenance: leaking faucet repair

- 2021-06-25-

Dripping water from a faucet is the most common problem with water pipes and one of the easiest to repair. However, many people ignore this problem and do not repair the dripping faucet without realizing that this might waste a lot of money. Continuous dripping will be wasted in a short period of time. I don’t know how much water is charged. Multiply the waste of water from each faucet by the number of dripping faucets in your home, and you can calculate how much money you have "flowing into" the sewer. And the dripping water from the hot water tap will waste even more, because you pay to heat the water before it flows into the sewer.

How to solve this problem? 
Dripping water is caused by leakage of the water supply. Don't forget that the water supply enters your home after pressurization, so when the faucet handle is in the "closed" position, there must be an impermeable gasket to block the inflow of water. This gasket is usually formed by pressing the gasket tightly on the faucet seat. Obviously, if there is something wrong with the gasket or the faucet seat, some water can seep out and drip from the faucet mouth. To prevent this kind of dripping, you usually only need to replace the gasket or repair the faucet holder.

How to fix dripping water from a faucet? 
The first thing you need to do is to turn off the water supply. You should only need to turn off a water supply valve near the faucet to turn off the water supply, but if not every faucet in your house is equipped with a water supply valve, you have to turn off the main water supply valve to shut off all the water supply in your home. The following is the method that Naizun Hardware has collected for you to solve the faucet dripping caused by various reasons. I hope I can bring help to friends in need!

1. Push-type faucet:

Regardless of the appearance of the push-type faucet, whether it has two handles for cold and hot water or only one handle that controls both hot and cold water, it works according to certain basic principles. The following is how to disassemble a push-type faucet and repair the dripping problem:

Tools needed: Use these tools to deal with push-type faucets-screwdrivers, penetrating lubricants, slip joint pliers or adjustable wrenches and their replacement pads.

Step 1: Turn off the water supply and remove the small screw on or behind the faucet handle to remove the handle fixed on the faucet body. Some screws are hidden under metal buttons, plastic buttons, or plastic sheets, which snap into or screw into the handle. As long as you turn on the button, you will see the handle screw on the top. If necessary, use some penetrating lubricant like WD-40 to loosen the screws.

Step 2: Remove the handle and check the parts of the faucet. Use large slip joint pliers or an adjustable wrench to remove the packing nut, being careful not to scratch the metal. Turn the spool or shaft in the same direction as when you turned on the faucet to unscrew them.

Step 3: Remove the screws holding the washer. If necessary, use penetrating lubricant to loosen the screws. Check the screws and spool, if they are damaged, replace them with new ones.

Step 4: Replace the old washer with an identical new washer. New washers that almost exactly match the old washers generally keep the tap from dripping. You should also pay attention to whether the old gasket has a bevel or flat, and replace it with the same new gasket. A gasket designed only for cold water will swell violently when hot water flows through it, blocking the water outlet, and slowing down the flow of hot water. Some gaskets can work in both hot and cold water, but you have to make sure that the replacement gasket you buy is exactly the same as the original one.

Step 5: Fix the new gasket to the valve core, and then reinstall the parts in the faucet. Rotate the spool clockwise. After the spool is in place, reinstall the packing nut. Be careful not to scratch the metal with the wrench.

Step 6: Reinstall the handle and put the button or disc back. Turn on the water supply again and check for leaks.

2. Valve seat of faucet:
If you change the gasket and the faucet still drips, then there may be a problem with the valve seat of the faucet. A damaged gasket may cause the valve seat of the faucet to be worn out by the metal valve core and become uneven, or the deposition of chemical substances in the water may form a residue, which prevents the gasket from being completely compressed with the valve seat.

How to repair a broken faucet holder? 
Of course, you can replace the entire faucet. Another option is to just replace the faucet holder. If you have the right tool-called a seat tightening wrench, then removing the old seat is a simple matter. Insert the valve seat tightening wrench into the valve seat, and then turn it counterclockwise. Once you have removed the old valve seat, please make sure that the new valve seat you bought is exactly the same as the original .
