What should I do if a press type faucet leaks water?
Preparation tools: screwdriver, penetrating lubricant, carp pliers or adjustable wrench and the pad to be replaced.
Steps for repairing faucets:
Step 1. Close the inlet valve. Remove the small screw above or behind the faucet handle to remove the handle fixed to the faucet body. Some screws are hidden under metal buttons, plastic buttons, or plastic sheets that are stuck or screwed into the handle. You just need to turn on the button and you will see the handle screw installed at the top. If you want to use some penetrating lubricating oil with specifications like WD-40 to loosen the screws.
Step 2: Remove the handle and inspect the components of the faucet. Use a large carp pliers or adjustable wrench to remove the packing nut, being careful not to leave scratches on the metal. Rotate the valve core or shaft in the same direction as when you turn on the faucet to unscrew them.
Step 3: Remove the screws that secure the washer. If necessary, use penetrating lubricating oil to loosen the screws. Check the screws and valve core, and replace them with new ones if there is any damage.
Step 4: Replace the old gasket with an identical new one. A new gasket that almost matches the old gasket can generally prevent the faucet from dripping water. You should also note whether the old gasket has a sloping surface or a flat surface, and replace it with the same new gasket. Washers designed only for cold water will expand violently when hot water flows through, blocking the outlet and causing slow flow of hot water. Some gaskets can work in both cold and hot water, but you should make sure that the gaskets you buy for replacement are identical to the original ones.
Step 5: Fix the new gasket onto the valve core, and then reinstall the various components in the faucet. Rotate the valve core clockwise. After the valve core is in place, reinstall the packing nut. Be careful not to leave scratches on the metal with the wrench.
Step 6: Reinstall the handle and replace the button or disc. Turn on the water supply again and check for any leaks.
Water leakage caused by the sealing ring of the faucet
Water leakage caused by the sealing ring of the faucet:
Dripping occurs when the faucet is turned off; Leakage occurs when there is water flowing from the faucet. If you see water gushing out from around the handle, your faucet is leaking; The first thing to do is to make sure that the sealing nut of the faucet is tight, but be careful not to scratch the nut with pliers or wrenches.
Here are the tools you need to replace the faucet seal ring: adjustable wrench, replacement faucet seal ring, Vaseline.
If you find that the reason for the leakage is not due to the loose nut, then you need to replace the sealing ring. The sealing ring of a faucet can be a tight sealing ring composed of one or more O-ring rubber rings, or it can be a thin rope or soft metal wire wrapped around the valve core under the packing nut.
When replacing the sealing ring of the faucet, follow the following steps:
Step 1: Turn off the water supply and remove the faucet handle.
Step 2: Unscrew the packing nut and remove both the nut and the old sealing ring from the valve core.
Step 3: Install a new sealing ring. If you are using a linear sealing material, wrap it around the valve core a few times. If it is a sealing material like soft metal wire, only wrap it around the valve core once.
Before reassembling the faucet, apply a thin layer of Vaseline oil to the threads of the valve core and the packing nut.
The O-ring of the 3 faucets can also cause water leakage from the faucet
The kitchen faucet has one or more O-rings to prevent water from gushing out from around the outlet. If the O-ring is worn out, you will see water flowing out at the bottom of the outlet every time you turn on the faucet.
The following are the tools required to replace the O-ring: an adjustable wrench, water pipe joint tape, and a replacement O-ring.
Steps for replacing O-ring:
Step 1: Turn off the water supply, rotate counterclockwise and remove the threaded connecting nut that fixes the water outlet. Be sure to wrap the nut with tape to prevent it from being scratched by pliers or wrenches.
Step 2: After removing the connecting nut, lift the water outlet upwards and take it out of the water outlet seat. You can see these rings inside the water outlet seat.
Step 3: Replace the faulty ring with a new one of the same size. Reassemble the faucet.
4. Leakage caused by faucet valve seat
If the faucet still drips after replacing the gasket, it is possible that there is a problem with the faucet seat. A damaged gasket may cause the faucet valve seat to become uneven due to the wear of the metal valve core, or the deposition of chemicals in the water may form residue that prevents the gasket from pressing against the valve seat.

How to repair a broken faucet seat? Of course, you can replace the entire faucet. Another option is to only replace the faucet seat. If there is the correct tool - called a valve seat wrench - then removing the old valve seat is a very simple task. Insert the valve seat wrench into the valve seat and then turn it counterclockwise. Once you remove the old valve seat, please make sure that the new valve seat you purchased is the same as the original one. If the valve seat cannot be removed, insert a suitable valve seat sleeve that can slide into the old valve seat and provide a seal. There are two types of valve seat rollers or grinders that can flatten worn valve seats.

Another option is to use a valve seat roller or grinder, which is an inexpensive tool that can flatten worn valve seats again. Be careful not to use this tool for too long or with too much force, as the valve seat is made of soft metal and you can easily wear it off too much.

When using a grinder, first remove the valve core of the faucet and insert the valve seat roller downwards into the valve seat in the faucet body. Rotate the tool clockwise a few times with moderate force. Then use a cloth to wipe off any metal shavings that have fallen off the valve seat.
