Drain Clogs: How to Plunge
When a drain is clogged--whether it's a sink, toilet, or tub--the first thing to do is try breaking up the clog by plunging it with a "plumber's helper." Be sure you have one on hand that has an elongated bell shape; the bell folds up so that the plunger becomes flatter and cup-shaped for sinks and tubs.


A plunger always works better if you put enough water into the fixture to cover the plunger. If the plunging doesn't break up the clog, either blast open the drain with a hose and hydraulic bladder or use a drain auger to snake out the drain.

To plunge a toilet, fill the bowl about half full. Push the bell-shaped end of the plunger down into the drain, and, maintaining a tight seal, rapidly pump 10 to 20 times with short strokes. If the water doesn't flush down, resort to a closet auger.

To plunge a sink or tub, first remove the strainer and pop-up. Stuff a rag or sponge into a plastic bag, and use this to plug the overflow hole. Fill the fixture with enough water to cover the plunger's flat rubber cup (fold the bell shape up inside).

Plunge steadily up and down 15 or 20 times; intersperse a few powerful pushes. Keep the plunger tightly sealed against the fixture. A plunger doesn't usually work on floor or shower drains, but it's worth a try; be sure the water level covers the plunger.
