How To Replace A Bathtub Overflow Gasket

The bathtub overflow drain is often overlooked as a source of a water leak coming from your tub. Many times, homeowners will begin to tighten threaded connections, replace faucet valves, or use silicone tape to seal connections. It may not make much sense that a faulty gasket in your overflow plate is the culprit for water leaking through a ceiling and running down the wall from an upstairs bathroom. 

One indicator that you should check the gasket in the overflow tube is if you do not notice the leak when someone is taking a shower or a bath without filling it up very full. When bathing children without filling the tub up to the overflow tube or when showering, you may not notice the leak if the water does not reach the overflow tube.

Replacing the Tub Overflow Gasket

Replacing a bathtub overflow gasket is actually very simple and inexpensive and is something you can do on your own. You can easily save a couple hundred dollars by doing this yourself instead of calling a plumber. The first thing to do is to remove the screws on the overflow cover plate. This is usually with a Phillips head screwdriver and may be one screw in the center or two screws on the sides. 

If you have a trip lever tub stopper or your bathtub stopper is controlled with a lever protruding out of the overflow plate, simply remove the screws and pull the cover out with the stopper assembly attached. Take a look at the rubber gasket that sits right behind the flange to hold the overflow plate, and if you notice the gasket is cracked or deteriorating, this is most likely the cause of your leaks.

You will need to simply remove the old gasket and work the new one snugly into place. A replacement overflow gasket is typically beveled, and in most cases, the thicker part should be towards the bottom. This is also a good time to replace your bathtub overflow plate altogether, and one of the easiest to install is the Watco Innovator® Snap-On bathtub overflow plate. 

Pair it with a matching push-pull bathtub stopper like the SimpliQuick® Tub Fix, also by Watco, for a matching, complete look to upgrade your tub.
