Missing, ill-fitted of loose sewer tap plugs can cause your plumbing to smell like the main sewer line. A house trap is a ‘U’-shaped pipe and has a small quantity of water at the bottom of the tap. The water in the tap acts as a barrier for the gasses in the sewer to escape into your plumbing. If this tap is not sealed properly, these gasses can escape and leak into your plumbing.

Dried out house trap sump
If the water barrier between the main sewer and your plumbing is dried out, it can cause sewer gasses to escape into your plumbing. All plumbing fixtures in your house have trapped. The trap allows retention of a small amount of water so that it forms a seal between the sewer and your plumbing. If the water in this trap is dried out, you can start smelling the sewer.
