Delta tub faucets contain rubber seats that look similar to washers as well as metal springs to help regulate the flow of hot and cold water through the faucet. When you start to see water leaking out of the spout, you will need to replace the worn seats and springs to correct the problem. With faucets that have two handles instead of one, you will need to feel the temperature of the water that is leaking to know which handle to remove.


Step 1

Turn off the water in the house by closing the main water valve. Turn on another faucet at a lower level to relieve any pressure left in the plumbing, if possible.

Step 2

Use either an Allen wrench or Phillips screwdriver to remove the screw holding the faucet handle in place. The screw will be located in the middle of the handle, under a decorative cap, or near the base of the handle.

Step 3

Pull the handle off the faucet or use a handle-puller tool to free the handle if it is stuck. Turn the nut that sits under the handle counterclockwise using an adjustable wrench to remove it from the faucet's stem.

Step 4

Pull on the stem to pull it out of the faucet. Remove the seats and springs from the faucet using a pair of tweezers.


Step 5

Cover the replacement seats and springs with plumber's grease, then put them into the faucet where the old seats and springs were located. Cover the ball on the end of the valve stem with plumber's grease as well, then reassemble the faucet by reversing the steps you took to take it apart.
