Here are a few simple steps remedy smelly drains.

Check for a P-Trap

P-traps are a necessary protector against foul smells. They prevent sewer gases from rising into your bathroom and causing unpleasant odors. A P-trap looks like the letter "p" or "u" in your drainpipe and you should be able to see it under your sink. If you have a P-trap, a plumber can inspect it to be sure it is functioning properly.

Look for Biofilm in the Drain

Another reason for smelly drains is a buildup of toothpaste, soap, shaving cream and skin cells. You probably use your bathroom sink daily. As this material builds up naturally over time, it can cause odors in the pipes. Thorough cleaning can help take care of the problem.

Have a Plumber Clean the Drain

To really remove foul smells from your drains, a plumber can clean the P-trap. First, your plumber will remove the P-trap and remove any buildup of sediment here. Your plumber will clean the drain, wash all parts of your sink, and drain assembly, replace them, and check for leaks. Your plumber will then disinfect the drains.
