Leakage of the faucet caused by Stainless Steel Bathroom Faucet seal:
Drip occurs when the faucet is closed; water leakage occurs when water flows through the faucet. If you see water flowing out of the handle, the faucet leaks; the first thing to do is to make sure the faucet's fill nut is tight, but be careful not to scratch the nut with a pliers or wrench.
Tools required to replace the faucet seal: adjustable wrench, replacement faucet seal, Vaseline.
If you find that the cause of the leak is not a loose nut, you will need to replace the seal. The seal ring of the faucet may be a tight seal ring composed of one or more O-ring rubber rings, or something similar to a string or a soft wire wound around the valve plug under the seal nut.
When replacing the faucet seal, follow these steps:
Step 1: Turn off the water supply and remove the faucet handle.
Step 2: Unscrew the sealing nut and remove the nut and the old sealing ring from the valve plug.
Step 3: Install a new seal. If you are using a linear seal, wrap it around the spool for a few turns. If it is a sealing material, such as a cord, it is only wrapped around the spool. Apply a thin layer of Vaseline oil to the threads of the spool and the threads of the sealing nut before reassembling the faucet.
