Our friends over at HomeAdvisor.com wrote this great tip for cleaning your drains
Most homeowners know how to work a plunger and pour chemical drain cleaners down a clogged drain. Yet, sometimes these measures are insufficient for drain cleaning. Either the drain remains clogged or the drain perpetually re-clogs. When this happens, often because something unusual was pushed or flushed down a drain (think children), more dramatic measures are needed.
Drain Cleaning
If a liquid drain cleaner doesn’t take care of the clog, physical drain cleaning is usually the only way to get rid of the clog. A plumbing snake should be fed down the pipe to see if the clog can be reached. For clogged sinks, you should also try cleaning the trap and feeding the snake down the pipe that way. Covering the overflow valve for sink drains can help build pressure and may help bust through the clog.
If this doesn’t work, a power auger that can more effectively cut through the clog will be needed. This machine should only be used by people who have some basic plumbing knowledge to avoid further harm to your draining system. Pipes aren’t indestructible. Nobody particularly revels in calling a plumber, but sometimes it’s the wisest and even the most frugal course of action. Be as specific as you can with the plumber on the phone and you may want to take the time to have him or her inspect all your house drains to reduce the risk of a return visit.
