Better Than An Ordinary Plunger
I recently bought this item as a last resort for my shower drain. It's been gradually getting slower and slower, even at times totally plugging up. I've tried every drain opener (and natural enzyme) product on the market, and also used a regular plunger, to little effect. Very annoying taking a shower while standing in water up to the ankles. This plunger, however, succeeds where nothing else has for me. When I get in the shower and turn on the water, I operate the plunger a few times, then stand back to watch the water begin to drain freely -- no more standing in water while showering! Just press the plunger down firmly over the drain to form a seal (using one of the two provided heads), then pump the handle up and down like a bicycle tire pump. This forces air (and hot water) down into the pipe, driving out clogging material. So simple, but it really works for me!
