How does an overflow drain work in a bathtub?
The water that enters the overflow hole, goes down a pipe which is connected to the tub floor drain. With a well-functioning overflow drain, excess water will flow out the overflow hole, through the pipe and into the drain so as not to cause any damage to your bathroom or anything under or around the tub.
Does a bathtub need an overflow?
Depending on the style of bathtub and its use, having an overflow drain is not always necessary. If your bathtub is a shower/bathtub combo or if your bathtub is a smaller model, then having an overflow drain isn’t necessary.

How do you stop a bathtub overflow?
The quickest and easiest way to stop a bathtub overflow is to use a reusable overflow cover. Simply place the cover over the overflow on your bathtub to seal it up and stop water escaping through the overflow and down the drain. Giving you a deeper soak.
Why is water coming out of the overflow pipe?
When an overflow pipe is dripping or running with water, one of the most common causes is a problem with a float valve. Float valves are found in toilet cisterns, cold water tanks and central heating feed and expansion tanks.
Can you fill the tub past the overflow?
Water will continue to fill the tub beyond the overflow drain, and the bathroom could flood if the shower is not turned off or a leak is not fixed.
How do you clean an overflow drain?
Baking Soda and Vinegar
Slowly add 1 cup of white vinegar on top of the baking soda. The mix will foam up and move down the drain. Leave the mix in the overflow hole for around 10 minutes, and follow up with boiling water to flush out cleaner and help sanitize the overflow drain.
What is the round thing in the bathtub?
That is the tub drain overflow plate, though it’s actually above the drain, not the faucet. (The opening in this plate leads to a tube that prevents the tub from overflowing by allowing water to run out even if the drain in the bottom of the tub is stopped.)
Can you flip a tub overflow drain?
