Replacing a damaged or cracked bathtub overflow pipe behind the wall requires accessing the plumbing from behind the tub enclosure. Cut an inspection or access opening in the drywall on the opposite side of the wall, unfasten the slip-joint nuts or cut the PVC pipe connections leading from the overflow elbow down to the sanitary tee, and remove the old assembly. Glue or solder a new PVC or brass overflow pipe kit in place using appropriate primer and solvent cement. Callout type="warning" title="Hygiene Warning": Shut off the main water supply and wear safety goggles when cutting waste pipes. Verification: Perform a leak test by running water down the overflow tube before patching the drywall.
