How to Repair a Leaky Delta Bathroom Faucet

A leaky faucet is a common household problem that can be easily fixed with a few simple tools. Here's a step-by-step guide on how to repair a leaky Delta bathroom faucet:

Materials you'll need:

Adjustable wrench
Phillips head screwdriver
Allen wrench (for some models)
Faucet repair kit (optional)

Step 1: Shut off the water supply

The first step is to shut 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 until they are fully closed.

Step 2: Remove the handle

Once the water supply is shut off, you can remove the handle. On most Delta faucets, the handle is held in place by a screw. Use a Phillips head screwdriver to remove the screw and pull the handle straight up.

Step 3: Remove the cartridge

Once the handle is removed, you will see the cartridge. The cartridge is a cylindrical-shaped piece that controls the flow of water. Use an adjustable wrench to loosen the cartridge nut, which is located at the base of the cartridge. Once the nut is loose, you can pull the cartridge straight out.

Step 4: Inspect the cartridge

Once the cartridge is removed, inspect it for any damage. If the cartridge is damaged, it will need to be replaced. If the cartridge is not damaged, you can simply clean it with a mild detergent and water.

Step 5: Reinstall the cartridge

If you need to replace the cartridge, insert the new cartridge into the faucet body. If you are cleaning the cartridge, insert the cleaned cartridge back into the faucet body.

Step 6: Tighten the cartridge nut

Use an adjustable wrench to tighten the cartridge nut. Do not overtighten the nut, as this could damage the cartridge.

Step 7: Reassemble the faucet

Push the handle back onto the faucet body and secure it with the screw. Turn on the water supply and check for leaks.
