What causes the shower drain to smell?
If you catch a whiff of the smell of rotten eggs coming from your shower drain, what you’ll actually be smelling is . This gas, also known as sewer gas, is produced by bacteria found in sewage or when it grows in your shower drain. The following are some reasons why you may end up with a smelly shower drain:
A P-trap that’s dry or dirty
A P-trap is a U-shaped pipe that attaches to drains in your home. Its shape is purposefully designed to trap water that will block gases from wafting into your home. When these gases leak into your home, this may be because your P-trap is dry or empty.
When there’s no water in the P-trap, stinky gases have no barrier that stops them from moving up the drain and into your space.
If raw sewage sips into your house’s pipes, this can cause a nasty, rotten egg smell. Levels of sulfur in your water can also contribute to this problem.
High sulfate levels in your water can corrode your pipes. The sulfate can react with the rods in your water heaters. This reaction creates gases like hydrogen sulfide which give off a rotten egg smell.
A clogged drain
If you notice that your water is taking time to drain, there is a high chance it’s clogged. Dirt that has managed to find its way into your drain can be attached to the stopper or cover.
Several things can clog your drain. Hair and lint are the biggest offenders. Over time, residue from your bath products or the dirt from your body can build a film around the walls of your drain pipe. This can end up blocking your drain. Clogs also result in a build-up of bacteria that gives off the rotten egg smell.
