call SERVPRO of East Honolulu to handle your water-damaged ceiling.
First, confirm that the overflow drain caused the flooding. Start by removing the bathtub access wall panel, located in the room opposite the tub faucet and shower head. If you don’t see water dripping from the plumbing, look inside for water pooling behind the wall. Small puddles are sure signs of leaks around the drain pipe or supply lines.
If it looks good, go back to the bathroom, and run the shower. Splash water on the tub faucet, and check behind the access panel again. If you still don’t see water dripping inside the access space, you’re dealing with a bad overflow drain.
These steps fix the problem.
Unscrew and remove the cover plate. Pull out the overflow drain assembly, including the plug. Take a look at the components for signs of damage.
If parts of the overflow drain are loose, clogged or corroded, replace the entire assembly. However, the source of the overflow leak is usually a worn gasket. In that case, continue with step 3.
Use needle-nose pliers and your fingers to gently remove the damaged overflow gasket from the pipe flange. Clean the exposed flange and surrounding surfaces with rubbing alcohol.
Lubricate the new gasket with plumber’s faucet grease, and take a look at its bevel. Position the gasket over the pipe flange with its thickest side on the bottom. Ease it around the opening in the overflow drain pipe.
Carefully work the gasket into place around the overflow assembly opening. Make sure it’s secure against the flange for an even seal. Let the gasket set for a few minutes.
Position the cover plate so that its overflow hole is located at the bottom of the installation. Reattach it by tighten each screw a little at a time. Alternating pressure as you work ensures even compression and a snug fit.
If water damage from the tub overflow isn’t extensive, you may be able to take care of it yourself. However, it’s best to let SERVPRO of East Honolulu handle the water-damaged ceiling.
