Clogs are cleared with plungers through the process of water displacement. The more water pushed towards the clog per plunge determines the ability of the plunger. Standard designed rubber cup plungers displace about 2 to 4 cups of water per plunge. The bellows design Master Plunger displaces between 8 to 10 cups per plunge, depending on the model.
I could not find a good plunger anywhere. Thankfully there was one on this site. It came on time and is as robust as I was hoping for.. Laura. LA. Wed Jun 10 2026
