Therefore, you need a stable system that’ll pass your bathed-water effectively without causing any problem to the bathtub.

This article will help you get a satisfying answer on the question, “How does a bathtub overflow drain work?” It’ll also highlight on Bathtub overflow drain installation.
How Does A Bathtub Overflow Drain Work
The model of an overflow
The bathtub drain is sectioned into two parts: the main drain and the overflow drain. The primary pipe is positioned at the bottom while the overflow drain is located some inches below the rim.
The two drains are both connected to tubes which are positioned below the bathtub, then emerged into one pipe. The overflow drain lacks a stopper unlike the main which has a plug or mechanical stopper.
How it works
Overflow saves you the clean-up effort and extensive damage in your bathing space. It is modelled to prevent an overflow before it takes place. Since it lacks the mechanism of stopping water from flowing, it continuously drains water that reaches its maximum level. It works well if the pipes are clog-free and if the water level stays a few inches below the rim of the bathtub. With the help of it, it prevents the water from splashing onto the floor.
The two types of overflow drain
The first type is a traditional overflow. With this kind of overflow, a hole is cut into the side of the bathtub, allowing collected water to drain. The second one is an integral overflow. It’s an unnoticeable opening created inside the tub to let out excess water.
Bathtub Overflow Drain Installation
Tools and materials
- Screwdriver
- Plumber’s putty or caulking
- Channel locks
The Process Required
1. Attach the waste and overflow assembly. Install the assembly, making sure the top of the overflow tube aligns with the overflow opening on the bathtub. The drain arm should align with the drain opening in the bottom of the tub. Use channel lock pliers or solvent glue to permanently weld PVC connections.
2. Connect the drain fitting. Apply plumber’s putty around the drain opening, put the rubber washer on the drain end. Thread the drain fitting into the drain arm and tighten it using a drain wrench.
3. Attach the overflow cover dish. Place the gasket between the wall of the bathtub and the mouth on the overflow tube. The thicker side of the gasket should face down. Place the cover plate overflow opening and screw it tightly.
4. Test the installation. Wipe any excess putty around the drain fitting. Run water into the drain as you ensure there is no leakage in the tub.

3. Install an overflow assembly. Insert the rod, linkage, and plunger through the tube overflow hole and let it drop down until the overflow cover lines up with the overflow drain hole. Install the screws with a screwdriver and tighten down.
4. Thread in a spout tub pipe through the tub spout hole and into the way connecting to the wall. Tighten using pliers.
5. Screw on the tub spout with the screwdriver. Finally, test if it's flowing water smoothly.
