How to Repair a Leaking Delta Bathroom Faucet

Is your Delta bathroom faucet leaking? Don't worry, it's a common problem that can usually be fixed quickly and easily. Here's a step-by-step guide to help you repair the leak:

Tools and Materials You'll Need:

Adjustable wrench
Phillips screwdriver
Replacement cartridge (if needed)
O-rings (if needed)
Plumber's putty or Teflon tape

Step 1: Turn off the water supply

The first step is to turn off the water supply to the faucet. This is usually done by turning the handles clockwise until they stop. If your faucet has a single handle, you'll need to use an adjustable wrench to turn the packing nut clockwise.

Step 2: Remove the faucet handle

Once the water supply is turned off, you can remove the faucet handle. On most Delta faucets, the handle is held in place by a screw or set screw. Use a Phillips screwdriver to remove the screw and then pull the handle straight up to remove it.

Step 3: Inspect the cartridge

Once the handle is removed, you'll be able to see the cartridge. The cartridge is a round or oblong-shaped piece of metal that controls the flow of water in the faucet. Inspect the cartridge for any signs of damage or wear. If the cartridge is damaged, it will need to be replaced.

Step 4: Remove the cartridge

If the cartridge needs to be replaced, you'll need to remove it. To do this, use an adjustable wrench to loosen the packing nut that holds the cartridge in place. Once the packing nut is loose, you can pull the cartridge straight out of the faucet body.

Step 5: Install the new cartridge

If you're replacing the cartridge, insert the new cartridge into the faucet body. Make sure that the cartridge is properly seated and then tighten the packing nut back into place. Be careful not to overtighten the packing nut, as this could damage the cartridge.

Step 6: Reinstall the faucet handle

Once the cartridge is installed, you can reinstall the faucet handle. To do this, simply push the handle straight down onto the faucet body and tighten the screw or set screw that holds it in place.

Step 7: Turn on the water supply

Once the faucet handle is reinstalled, turn on the water supply and check for leaks. If there are no leaks, your faucet repair is complete.

Tips:

If you're not sure what type of cartridge your faucet has, you can consult your Delta faucet owner's manual or contact Delta customer service.
If your faucet is leaking from the base, it may be necessary to replace the O-rings. O-rings are small rubber gaskets that create a seal between the faucet body and the handle or spout.
If you're having trouble stopping a leak, you may need to apply plumber's putty or Teflon tape to the threads of the packing nut.
If you're not comfortable repairing the faucet yourself, you can call a plumber to do it for you.
