Why Do My Drains Smell Horrible and How Do I Prevent This?
Drains are designed to prevent smells from coming back inside your home, so if you suddenly find yourself wrinkling your nose whenever you enter the bathroom, there is a problem. Fortunately, it is almost always an easy one to fix. The vast majority of odd smelling drains are the result of a dried out trap.
Every drain has a U-shaped trap designed to hold a small amount of water at all times. This water blocks sewer gasses from travelling back up your plumbing and into your house. When the trap dries out, there is no barrier and you’ll begin to notice a smell when you enter the room. The simple solution is to pour water down drains in your house that aren’t used often. If this doesn’t resolve the problem, you’ll need to call a professional who can thoroughly inspect your system to track down the problem.
