Took care of a bathroom sink clog in the first use of this tool! No more Draino needed so far. Works great.

Didn’t know a device like this exist. The built is very sturdy. The pressurized pump works as described, strong powerful release, so strong that I was afraid it might burst the inside pipes 😎

Correct

Holding air okay for now.

Worked like the charm. Very powerful. I had to use it recently and it cleared up without an issue

We haven't clogged anything yet since receiving this Air Pump Plunger -- but it looks like it is constructed well and like it would work providing that a good seal is made.
