Remove, Replace, Repair Your Bath Tub Overflow Drain



Installing a Bathtub Over Flow Drain

UPDATED: July 25, 2017

The waste and overflow is the drain mechanism behind and under the bathtub that connects the overflow with the tub drain. It?s usually covered with a chrome plated cover above the tub drain near the top of the tub level. It allows water to drain out of the tub in the event the water is left on or the level gets too high when someone gets in and the water is displaced. Usually, the complete repair of the waste and overflow is time-consuming and difficult. As you can see there is no easy way to get to the drain unless you have a point of access in a wall behind the drain or from underneath the tub. We?ve got the best method for you, so let?s jump right into these step-by-step instructions.

When a waste and overflow needs to be repaired the plumbing technician needs to get access either underneath the tub or more preferably behind the tub. If this is a waste problem, locate the hair or loose odds and ends that is causing the clog and remove it. If you?re the drain remover, you?re definitely going to want to keep your eyes peeled for the next few steps when working on the tub overflow drain.

The first step to installingÿbathtub overflow drain isÿremoving the waste and overflow is to remove the overflow cover. The removal of the cover is an easier part of the process. This overflow cover is usually directly above the plug that drains the water on the bottom of the tub. You usually don?t need a tool to do this. The second and much more difficult step is to unscrew the tub drain from the shoe. The tub drain threads into the drain shoe body of the waste and overflow and snugs up both to the bath tub.

When you remove the drain stopper most times there are crossbars that the stopper is attached to, these are used to back the drain out. You also might run into a drain flange which is the finished and visible part around your drain hole. The drain flange helps seals the tub and drain assembly.

Quite often the drain breaks, making this job a time consuming project. (We will expand upon removing and replacing a waste and overflow). Here is another place where this can become difficult. If you?ve got access to the drain from behind the tub there is usually a slip nut that connects the drain to the drainage piping, this is a fairly easy installation, if not it is very difficult to remove the drain from below. Most times you have to cut it out and piece it back together. It is not unusual for a waste and over repair to take 6 hours or so.

The drain cover?s finish is the most apparent reason for changing it. The finish tends to pit or peel. The waste and the tub overflow cover usually has one screw in the middle or two to secure the cover to the body of the waste.

The single biggest reason a waste and overflow leaks is the gasket behind the drain cover or faceplate. The rubber behind the tub begins to break down and when the water level rises to the level of the overflow the water makes it?s way to any breach in the seal. Sometimes these leaks can be tricky to find because the water may run down the drain waste tube and the leak shows itself right at the spot of the waste and overflow or the water can run along and under the tub and shows itself quite a distance away from the actual leak.
