How to Fix a Leaking Delta Faucet

Identify the Source of the Leak

The first step to fixing a leaking Delta faucet is to identify the source of the leak. This can be done by following these steps:

1. Turn off the water supply to the faucet. This is usually located under the sink.
2. Remove the faucet handle by unscrewing the set screws on the back of the handle.
3. Look inside the faucet body to see where the leak is coming from.

There are three common sources of leaks in Delta faucets:

  • Dripping faucet: This is the most common type of leak. It occurs when the faucet is turned on, but not all the way. The water drips out of the faucet spout and onto the sink.
  • Leaking cartridge: The cartridge is a small, cylindrical part that sits inside the faucet body. It controls the flow of water through the faucet. If the cartridge is leaking, you will see water coming out of the faucet spout even when the faucet is turned off.
  • Leaking O-ring: The O-ring is a small, rubber ring that seals the cartridge in place. If the O-ring is leaking, you will see water coming out of the faucet body.

Step 1: Turn off the water supply to the faucet

The first step is to turn off the water supply to the faucet. This will prevent any further damage from occurring while you’re working on the repair.

To turn off the water supply, locate the shut-off valve for the faucet. This valve is usually located near the faucet, and it may be a ball valve or a gate valve.

Turn the valve clockwise to turn off the water supply.

Step 2: Remove the faucet handle

The next step is to remove the faucet handle. This will give you access to the cartridge or O-ring, which is the part that is most likely causing the leak.

To remove the faucet handle, you will need a Phillips head screwdriver.

Locate the screws that hold the faucet handle in place. These screws are usually located on the back of the handle.

Use the screwdriver to unscrew the screws.

Once the screws are removed, you can lift the faucet handle off of the faucet.

To do this, you will need a faucet wrench.

Use the faucet wrench to loosen the setscrews.

Once the setscrews are loosened, you can remove the cartridge from the faucet body.

Inspect the cartridge for damage. If the cartridge is damaged, you will need to replace it.

To inspect the O-ring, you will need to remove the stem from the faucet body.

To do this, you will need to use a pair of pliers.

Grasp the stem of the faucet with the pliers and twist it counterclockwise.

Once the stem is loosened, you can remove it from the faucet body.

Inspect the O-ring for damage. If the O-ring is damaged, you will need to replace it.

Grasp the stem of the faucet with the pliers and twist it clockwise.

This will install the new O-ring on the stem of the faucet.
