Is your faucet dripping? We’ll show you how to fix three types of two handle faucets—ceramic disc, compression and cartridge. First – determine which side is leaking by turning off the shut off valves one at a time. If the leak doesn’t stop on the first valve, it’s the other line that’s leaking. For stuck shut off valves turn off the water at the main valve. After you’ve determined which side is leaking turn off both water supplies. Then turn on the faucet to release any residual water. Close the drain and place a towel in the sink to help protect the sink. Remove the aerator. If it won’t unscrew, soak a towel in white vinegar and wrap it around the aerator to help loosen mineral deposits. After an hour, gently twist off the aerator. As you’re working lay the parts in order and snap a picture to help with reassembly.

Put them in a plastic bag and take them to the store. Your faucet repair may only require one specific part, but it’s usually best to get a new kit and replace everything. Also buy a new aerator if yours is damaged. Keep in mind these directions are typical, but check the manufacturer’s instructions for your faucet. To repair a ceramic disc faucet, loosen the set screw and take off the handle. Remove the retainer nut and pull out the cylinder. Rather than repairing the discs and seals, it’s best to buy a new cylinder.

Set it in, and reassemble the faucet. With compression and reverse-compression faucets, you’ll need to replace the washer and O-ring or gasket on the valve stem, and the valve seat in the faucet. First, take off the handle, then unscrew the valve stem. On the stem remove the old gasket, screw and seat washer. Apply some plumber’s grease and add a new gasket, seat washer and screw. Next remove the valve seat with a seat wrench or hex wrench, and insert a new one. Then put everything back together. To fix cartridge faucets, unscrew the set screw to take off the handle.

Then remove the retaining clip or nut. Gently pull out the cartridge. Pop in a new cartridge, and reassemble the faucet. For all faucets turn on the supply valve slowly, and without the aerator, let the water run for a few minutes to flush out any debris. Clean a dirty aerator by soaking it in white vinegar. Rinse it and screw it back in. And that should solve your faucet leaks.
