Delta Bathroom Faucet Cartridge Replacement

Delta bathroom faucets are known for their durability and style, but even the best faucets can eventually start to leak. If your Delta bathroom faucet is leaking, it's likely that the cartridge needs to be replaced. Replacing a Delta faucet cartridge is a relatively easy job that can be completed in about 30 minutes.

Here's what you'll need:

Replacement Delta faucet cartridge
Adjustable wrench
Phillips screwdriver
Rags or towels

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.
Remove the handle. There should be a small set screw on the side of the handle. Use a Phillips screwdriver to remove the screw, then pull the handle straight up to remove it.
Loosen the packing nut. The packing nut is located just below the handle. Use an adjustable wrench to loosen the packing nut, but do not remove it completely.
Pull out the old cartridge. Once the packing nut is loose, you should be able to pull the old cartridge straight out of the faucet body.
Insert the new cartridge. Align the new cartridge with the faucet body and insert it into the hole. Push the cartridge in until it is fully seated.
Tighten the packing nut. Use the adjustable wrench to tighten the packing nut until it is snug. Do not overtighten the packing nut, or you could damage the cartridge.
Reinstall the handle. Align the handle with the cartridge and push it down until it is fully seated. Tighten the set screw to secure the handle.
Turn on the water supply and check for leaks. Open the faucet and check for any leaks around the handle or base of the faucet. If there are any leaks, tighten the packing nut or set screw until the leak stops.

Replacing a Delta faucet cartridge is a simple job that can be completed in just a few minutes. By following these steps, you can easily fix your leaking faucet and get it back in working order.

Troubleshooting

If you are having trouble replacing the cartridge in your Delta bathroom faucet, there are a few things that you can check:

Make sure that you have the correct replacement cartridge. There are different cartridges for different models of Delta faucets, so it's important to make sure that you have the right one for your faucet.
Make sure that the packing nut is tight enough. If the packing nut is too loose, it could allow water to leak around the cartridge.
Make sure that the cartridge is fully seated in the faucet body. If the cartridge is not fully seated, it could also cause a leak.
If you are still having trouble, you can contact Delta customer service for assistance.
