Like other Delta faucet designs, the single handle tub faucets contain wearable parts that over time will allow water to pass through the faucet freely. If the faucet has started to drip water or if you have difficulty shutting the water off completely when using the tub, the faucet needs to be repaired. Replacing the Delta faucet’s springs, seals and rubber seats does not require specialized plumber skills. If you are unsure what replacement kit to buy for the faucet, take the old parts with you to the store for comparison.

Shut off all water to the tub’s faucet by shutting off the house’s main water supply. Open a faucet on a lower floor, if possible, relieving any pressure in the water pipes.
Remove the center cap on the faucet’s handle by hand. Remove the screw in the center of the handle using a Phillips screwdriver.
Remove the handle by sliding it directly off the spindle, or use a handle remover tool if the handle is stuck. Remove the retaining nut using a wrench to turn it counterclockwise.
Pull out the ball and stem and use tweezers if necessary to remove any springs or rubber seats left inside the faucet assembly.
Install the new springs, seats and seals in the faucet assembly or on the ball and stem, then put the faucet assembly back together. Turn the water supply back on and open the faucet to verify you have reassembled it correctly.
