The Basics of a Bathtub Overflow Drain

A bathtub overflow drain is a safety feature that prevents flooding in the event that the main drain becomes clogged. It is located at the top of the bathtub, just below the overflow lip. When the water level in the bathtub reaches the overflow lip, it flows over the lip and into the overflow drain. This prevents the water from overflowing onto the floor and causing a flood.

How the Overflow Drain Prevents Flooding

The overflow drain is designed to work in conjunction with the main drain. The main drain is the primary way for water to drain from the bathtub. The overflow drain is a backup in case the main drain becomes clogged. When the water level in the bathtub reaches the overflow lip, it flows over the lip and into the overflow drain. This prevents the water from overflowing onto the floor and causing a flood.

How to Clean and Maintain Your Bathtub Overflow Drain

To keep your bathtub overflow drain working properly, it is important to clean it regularly. You can clean the overflow drain with a few simple steps:
