The overflow drain is a small component on your bathtub, but it can cause big problems. The overflow drain is designed to do precisely what the name implies, which is to prevent excess water from spilling out over the bathtub’s walls. When the overflow drain is working correctly, it channels excess water into the drainpipes to keep the water below the overflow level. But when the overflow drain stops working, water can seep (sometimes pour!) over the sides of the bathtub and cause tremendous damage. Naturally, a malfunctioning overflow drain is best addressed as soon as possible. But is it a problem you can fix yourself, or should you call in the Henderson best plumber instead?

Experts say that the difficulty level for an overflow drain repair is “moderate.” If you have the right tools and some basic knowledge of your home’s plumbing system, you may be able to handle the repairs yourself. At a minimum, you should have the following tools and repair accessories on hand: screwdrivers, utility knife, caulk, and replacement overflow gasket.

Getting Started: Find the Problem

The first step in repairing an overflow drain leak is finding the source of the problem. If you notice water pooling on the floor around the bathtub, the issue can stem from a loose or cracked overflow tube gasket, a faulty shower valve, or a worn tub drain fitting. You might not know where exactly the problem is coming from, but a simple diagnostic test can find the root cause. First, try running water in the bathtub to see if it leaks out. If it does, you probably have a loose connection in the drain trap or drain fitting. If no water leaks out when you turn on the faucet, check for leaks in the showerhead, faucet plate, or tub spout. If they’re not leaking, a bad overflow tube is likely to blame.

Check the Overflow Pipe

An overflow pipe is designed with a gasket. Over time, the gasket can get worn out and compressed. When this happens, it starts causing leaks. To check the gasket, begin by removing the bathtub overflow cover plate. Once you’ve done that (a process that might require caulk), you can check to see what kind of condition the gasket is in. If it appears to be worn out, you can easily find a replacement at your local hardware store or home repair center.

If you’re suffering from the problem, you know what a pain your bathtub’s overflow drain can be. But you also know that you can fix it! By following a few simple steps, you can find the cause of a leaking bathtub. Fortunately, the overflow drain can easily be replaced.
