How To Repair A Leaking Double Handle Faucet

QUESTION: How do I repair a leaking faucet on my bathroom sink? My bathroom faucet constantly drips water. The faucet is turned off but still leaks. The faucet has 2 handles and leaks 1 drop every 5 seconds. What is the easiest way to fix my leaking bathroom faucet?

ANSWER: A part in the faucet is worn out and needs to be replaced. Depending on the type of your double handle faucet, the faucet contains either a CARTRIDGE, COMPRESSION/REVERSE COMPRESSION, or CERAMIC DISC type. These components wear out with time and will need to be replaced or repaired when found to be leaking.

Which side is leaking on my faucet?
To find out which side is causing the leak, turn off one of the water supply valves under the sink. If the water stops leaking, then you found the correct side that is leaking. If the water still leaks from the faucet, then you know the other side is leaking. Remember to turn off both water supply valves when repairing your leaking faucet.
