Metal Overflow Cover Tester by Bender Devices is a professional-grade bathtub overflow drain test tool designed for plumbing inspectors, licensed plumbers, and property managers.
How It Works
The tool uses a metal hook that latches directly into the tub's overflow drain cover, creating a watertight seal so you can fill the tub and test for leaks behind the wall. The hook is metal because plastic hooks were found to rip out and damage plastic overflow drain covers during use. This version is designed for use on metal and cast iron overflow covers only.
If your tub has a plastic overflow cover, use the Universal Bathtub Overflow Tester instead — it uses suction cups and requires no hook.
