Review on 🚽 Master Plunger MP500: The Ultimate Heavy Duty All Purpose Plunger for Commercial & Residential Use – Ideal for Laundry Tubs, Bath Tubs, Kitchen Sinks, Garbage Disposal, and Toilets. With Air Release Valve and Powerful Plumbing Performance by Justin Olson

This piston didn't fit me. I received it on April 28, today is May 9, I download 3-4 times a day, it just doesn't work. I dive with a toilet full of water, I dive with low water. This product doesn't stick well to my toilet. Most reviews are positive so give it a try, it might work for you. At least with Revain Prime, they're good at picking up their stuff when that doesn't work. I ordered a corner queue for the toilet. hope this works
