Replace Cartridge Delta Bathroom Faucet

A dripping faucet is not only annoying, but it can also waste a lot of water. If your Delta bathroom faucet is dripping, it's likely that the cartridge needs to be replaced. Replacing a Delta faucet cartridge is a relatively easy task that can be completed in about 30 minutes.

Here's what you'll need to get started:

New Delta faucet cartridge
Phillips head screwdriver
Adjustable wrench
Bucket or bowl

Once you have your tools and materials, follow these steps to replace the cartridge:

Turn off the water supply to the faucet. There should be two shut-off valves under the sink, one for hot water and one for cold water. Turn both valves clockwise to turn off the water.
Open the faucet to release any remaining water in the lines.
Place a bucket or bowl under the faucet to catch any water that may leak out.
Using a Phillips head screwdriver, remove the two screws that hold the handle in place.
Pull the handle straight up to remove it.
Using an adjustable wrench, loosen the packing nut that holds the cartridge in place.
Pull the cartridge straight out of the faucet body.
Inspect the old cartridge for any damage. If the cartridge is damaged, it will need to be replaced.
Insert the new cartridge into the faucet body. Make sure that the cartridge is properly aligned.
Tighten the packing nut using an adjustable wrench.
Reinstall the handle and secure it with the two screws.
Turn on the water supply to the faucet and check for leaks.
