Perfect for performing leak tests. My plumber recommended this to test a drain seal and it worked perfectly.

Used these to plug vent and sink while forcing pressurized water through cleanout to unclog the drain line and worked like a charm. Really handy tool to have.

I plugged a 2” cast iron shower drain to test the shower liner. It was very loose fitting and easily expanded to make a tight fit. I used a bicycle pump and had no trouble getting it down to the proper level with the pump attached. Very good product.
