Plungers are inexpensive and is possibly the first tool you grab when a sink, toilet, drain or bath needs unblocking. The first type of plunger we will look at is the Common Sink Plunger or the Cup Plunger. As the name suggests it is the most common type of plunger. Since drain clogs are such a common plumbing problem, dealing with them can become expensive if you call a plumber to clear every stoppage.
A plunger works its magic by simple suction and pressure.
