A foul odor coming from your bathroom sink can be a major annoyance and a sign of a bigger problem. If you have a septic tank system, the smell may be even more pungent and persistent. But what exactly causes this unpleasant scent and how can you get rid of it? In this article, we will explore the top 10 main causes of septic smell coming out of your bathroom sink and provide solutions to eliminate it. Septic Tank Smell in Bathroom Sink: Causes and Solutions
Septic Tank Smell in Bathroom Sink
One of the most common causes of septic smell in your bathroom sink is a clogged drain. Over time, debris such as hair, soap scum, and toothpaste can build up and block the drain, preventing proper flow of water and causing stagnant water to emit a foul odor. If you notice slow draining or gurgling sounds when using the sink, it’s likely that you have a clogged drain. Use a plunger or a drain snake to clear the blockage and get rid of the smell. 1.

The P-trap is a curved pipe under your bathroom sink that traps water and creates a seal to prevent sewer gases from entering your home. If the P-trap dries out, it can no longer block the gases, resulting in a strong septic smell. This usually happens if the sink is not used for an extended period of time, such as in a guest bathroom. To eliminate the smell, simply run some water in the sink to refill the P-trap. 2. Dry P-Trap
