Repair method for water leakage caused by faucet sealing ring

Dripping occurs when the faucet is turned off; Water leakage occurs when there is water flowing out of 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.

Tools required for replacing the faucet seal ring: adjustable wrench, replaced faucet seal ring, Vaseline. If you find that the cause of the water leakage is not due to loose nuts, then you need to 

replace the sealing ring.

The sealing ring of the faucet can be a tight sealing ring composed of one or more O-ring rubber rings, or something like 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 steps below:

1. Turn off the water supply and remove the faucet handle.

2. Unscrew the packing nut and remove both the nut and the old sealing ring from the valve core.

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 such as 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 packing nut.
