How to Repair a Leaky Delta Tub Faucet?

A leaky Delta tub faucet can be a major annoyance, and it can also waste a lot of water. If you’re tired of dealing with a leaky faucet, you can fix it yourself with a few simple tools and some basic plumbing skills.

This guide will walk you through the steps of identifying the source of the leak, determining the cause of the leak, and repairing the leak.

1. Identifying the Source of the Leak

The first step in repairing a leaky Delta tub faucet is to identify the source of the leak. There are a few common places where leaks can occur on a Delta tub faucet:

  • Under the sink. If you see water pooling under the sink, there’s a good chance that the leak is coming from the faucet’s supply lines. To check for a leak under the sink, turn on the water to the faucet and look for any signs of water coming from the supply lines.
  • Around the faucet handle. If you see water dripping from the faucet handle, the leak is likely coming from the faucet cartridge. To check for a leak around the faucet handle, turn on the water to the faucet and look for any signs of water coming from the handle.
  • Around the faucet spout. If you see water dripping from the faucet spout, the leak is likely coming from the faucet spout itself. To check for a leak around the faucet spout, turn on the water to the faucet and look for any signs of water coming from the spout.
  • Around the faucet base. If you see water pooling around the base of the faucet, the leak is likely coming from the faucet’s drain assembly. To check for a leak around the faucet base, turn on the water to the faucet and look for any signs of water coming from the drain assembly.

Once you’ve identified the source of the leak, you can move on to the next step: determining the cause of the leak.

2. Determining the Cause of the Leak

Once you’ve identified the source of the leak, you need to determine the cause of the leak. There are a few common causes of leaks on Delta tub faucets:

  • Loose or damaged O-rings. The O-rings on a Delta tub faucet help to seal the faucet and prevent leaks. If the O-rings are loose or damaged, they can allow water to leak out of the faucet.
  • Worn or damaged washers. The washers on a Delta tub faucet help to create a watertight seal between the faucet and the plumbing. If the washers are worn or damaged, they can allow water to leak out of the faucet.
  • Clogged cartridge. The cartridge on a Delta tub faucet contains a number of small parts that work together to control the flow of water. If the cartridge becomes clogged, it can prevent the faucet from working properly and can also cause leaks.
  • Damaged faucet body. If the faucet body itself is damaged, it can allow water to leak out of the faucet. This is a more serious problem than a leak caused by loose or damaged O-rings, washers, or a clogged cartridge, and it will require more extensive repairs.

Once you’ve determined the cause of the leak, you can move on to the next step: repairing the leak.

3. Repairing the Leak

Once you’ve identified the source and cause of the leak, you can repair the leak yourself. The following steps will walk you through the process of repairing a leaky Delta tub faucet:

1. Turn off the water to the faucet. To do this, find the shut-off valve for the faucet and turn it clockwise until it is completely closed.
2. Remove the faucet handle. To do this, you will need to remove the screws that hold the handle in place. Once the screws are removed, you can lift the handle off of the faucet.
3. Remove the faucet spout. To do this, you will need to remove the screws that hold the spout in place. Once the screws are removed, you can lift the spout off of the faucet.
4. Remove the faucet base. To do this, you will need to remove the screws that hold the base in place. Once the screws are removed, you can lift the base off of the faucet.
5. Inspect the faucet for damage. Look for any cracks, leaks, or other damage to the faucet body. If you find any damage, you will need to replace the faucet.
6. Repair the leak. If the leak is caused by loose or damaged O-rings, washers, or a clogged cartridge, you can repair the leak by replacing the damaged parts. To do this, you will need to remove the old parts and install the new parts.

3. Repairing the Leak

If you have determined that the leak is coming from your Delta tub faucet, you can fix it yourself by replacing the O-rings, washers, cartridge, or faucet body.

Replacing the O-rings

The O-rings are small, rubber rings that seal the faucet’s moving parts. If they are worn or damaged, they can allow water to leak. To replace the O-rings, you will need to:

5. Apply a thin coat of plumber’s grease to the new O-rings.
6. Insert the new O-rings into the faucet.
7. Reassemble the faucet.
8. Turn on the water supply to the faucet and check for leaks.

Replacing the washers

The washers are small, metal discs that sit between the faucet’s moving parts. If they are worn or damaged, they can allow water to leak. To replace the washers, you will need to:

2. Remove the faucet handle.
3. Remove the faucet escutcheon (the decorative cover around the faucet).

1. Turn off the water supply to the faucet.
2. Remove the faucet handle.
3. Remove the faucet escutcheon (the decorative cover around the faucet).
4. Remove the old cartridge.
5. Insert the new cartridge into the faucet.

1. Remove the faucet from the sink.
2. Remove the old faucet body.
3. Apply a sealant to the new faucet body.
4. Insert the new faucet body into the sink.
5. Reattach the faucet to the sink.
