Sometimes the bathroom sink can smell bad. There are several reasons why the bathroom sink has a bad smell. The bathroom sink has a drainage pipe that connects it to the septic tank. Systems such as the p trap and the drainage pipe should work well; if one of the parts of the bathroom sink is not working well, there are high chance the bathroom sink will start smelling. A wide range of issues can contribute to a smelly bathroom sink. Here are common causes:

Clog

One of the main reasons for a smelly bathroom sink is the development of clogs. The drainage pipe may develop clogs in a bathroom from the grease released into the drainage pipes. For example, the soap’s skin, hair, soap residue, and scum will end up clogging the drainage pipe with time. The trapped grease and soap residue will start rotting in the pipe and cause a bad smell. If you realize a bad smell is coming from the sink, check out for possible clogs and unclog the drainage pipes.

Contaminated Water Heater

Sometimes the bad smell on the skin can come from the hot water. The anodized rod in the water heater is responsible for stopping the corrosion of the interior parts of the water heater. The affected anodized rod can contribute to a bad smell from the sink. The bad smell issue can be tackled by getting a replacement of the anodized rod to avoid corrosion in the water heater that may be causing the bad smell.

Bacteria in the faucets

If the faucets have bacteria, they will attack any solid particles released into the sink and lead to a bad odor. The sink tends to drain down the dead skin and other small particles as you take a shower. The bacteria can attack the small particles and lead to a bad odor. Get a strong detergent and wash the sink to kill the bacteria. Hot water can as well work in killing the bacteria.

Full Septic Tank

The bad smell may be coming from the septic tank; get a plumber to check out the tank’s level and take corrective measures. A full septic tank will lead to a foul odor. It is recommended to clean the septic tank regularly, but if it reaches a time when it is too full, it will cause a foul odor in your sink.

Dry P-trap

During the plumbing process, a p-trap is placed below the sink. The p-trap contains water to prevent gases from escaping from the sewer into the sink and the home. The water trapped acts as a barrier; if the water is dry, the sink will tend to develop a bad odor. Get a professional plumber for advice on the right way to repair the trap.

Faulty Vent Pipes

The main purpose of the vent pipe is to carry sewer gases through the roof. If the vent pipes are damaged, they will lead to a foul odor. Get tips from a professional plumber on how to repair the vent pipes.
