Sinks get clogged and backed up when soap, hair and grease build up and clog the trap or the drain line. When that happens, don't reach for the drain cleaner or call plumbing repair services for help. This guide will teach you to clear the drain by cleaning gunk off the sink stopper or plunging the sink.
Remove the Sink Stopper
Take the stopper out of the sink. Some older stoppers have a pivot rod that has to be removed. Under the sink, you'll see a locking nut where the rod enters the drain pipe. Remove the nut, and pull the rod out. Have a rag close at hand when removing the locking nut a small amount of debris may spill out.
Use the Plunger
Stuff a wet rag in the sink overflow opening and replace the nut and rod without the stopper. This prevents air from escaping as you work with the plunger. Place the plunger cup over the drain opening, and run enough water to cover the rubber cup. Move the plunger up and down rapidly to clear the clog.
If these methods don't work, consider renting more heavy-duty drain cleaning tools from the Home Depot Tool Rental Center. Plumbing tools available include small, medium and large drain cleaners as well as augers, pumps, drain cameras and others.
