How to Fix a Leaky Double-Handle Faucet
Keep in mind that some cartridge bodies and ceramic disc bodies/cylinders look similar. In most cases, the cartridge body doesn't have moving parts. The ceramic disc body/cylinder does have moving parts that pivot to open the ports on the bottom.
If your kitchen or bathroom sink is leaking, follow these instructions. The repair steps below are standard, but always refer to the manufacturer's instructions for your faucet too.
Locate the Faucet Leak
Determine which side of your faucet is leaking by shutting off the water supply valves one at a time. If the faucet leak doesn’t stop after the first valve is turned off, it’s the other line that’s leaking.
Once you determine which side of the faucet is leaking, turn off both supply valves.
If your valves are stuck, shut off the water main. You’ll have to replace hardware for both sides since you won’t be able to identify whether the hot or cold side is leaking.
Turn faucet handles on to release any residual water. Close the drain and place a towel in the sink to protect the surface and catch dropped parts.
Disassemble the Double-Handled Faucet
Remove the faucet aerator and inspect it for damage. If it’s stuck, soak a towel in vinegar and wrap it around the faucet aerator to loosen mineral deposits. After an hour, gently twist the aerator with a towel and pliers.
As you disassemble the old faucet, lay the parts in order on a flat surface and snap a picture for reference. Put those parts in a plastic bag and take them to the store with you when shopping. You may require only one part, but it may be best to buy a kit and replace everything, including a new aerator if yours is damaged.
