: Have a Delta faucet in my shower need to know how to fix dripping. Not a tub shower.
Is the drip hot or cold? If hot, go to the water heater and shut off the cold water into the heater.Then go to the shower pry the little plastic cap off the center of the delta hot faucet handle, remove the screw inside, pull the handle off, unscrew the packing nut, remove the valve stem, and look at its base to find a valve seat washer. Take it to the local plumbing supply house for a replacement. Ask them to look at the seat and try to determine if it needs to be resurfaced. Expect to do the same on the cold soon.
