What is a "waste and overflow"?

The waste and overflow assembly is the drain under the tub spout in your bathtub that makes sure that if you run too much water into the bathtub that it doesn't overflow onto the floor. If you have a bathtub, there are several different reasons to make sure that you need to keep your waste and overflow drain clean and functional. You may not realize that the little lever to stop draining the water out of your tub is actually part of an overflow system to help prevent the water from overflowing of the tub. If you run a bath and you forget to turn the water off when the phone rings, you'd better hope this waste and overflow system is working.

In order to understand your waste and overflow system, you must understand the different parts. The most important part of a waste and overflow system is the triplever plate. The triplever plate has the switch you flip up when you want to run a bath, and then the lever that you flip down when you want to drain the water after a bath.

However, the triplever is actually more important than you might think. This is because it is the main control on your waste and overflow system. It installs with screws, which can be coordinated in the same color as the triplever. Trip levers generally come in chrome and brass, but usually come from companies that also coordinate the finishes with the rest of your bathroom faucets.

These are the cosmetic parts of a waste and overflow system, but there are also parts that you won't ever see and probably need a plumber to replace if you have a problem. This includes parts like the overflow gasket, the overflow bracket, the bucket and rod assembly, a grid strainer, and of course the drain itself.
