Difficulty: Moderately Easy
Things You’ll Need:
Step1
Unscrew the showerhead from the pipe coming out of the wall. This can be done by hand but sometimes requires a crescent wrench or large pliers. The head may be held on with a screw, which you'll have to remove.
Step2
Look at the threads inside the showerhead where it screws into the pipe. There should be a small washer made of plastic or a rubber O-ring. Replace it if it looks even a little damaged or brittle.
Step3
Wrap the showerhead stem with Teflon tape or pipe sealer (pipe dope) to seal the connection.
Step4
Remount the showerhead on the stem. Don't overtighten. Hand-tightening should suffice.
Step5
Turn the water on and off. Wait several minutes and check for drips or leaks. If the showerhead is still leaking, you may have problems with the shower's water-control valve and need to call an expert.
