S-Traps are very common to see on a home inspection. But what is an s-trap and what is the issue with them?

An s-trap is what we see in the picture above. It is the drain line in the shape of an “S”. The more common type that we see nowadays is the “P” trap. P-traps are known to work better and are often required now by code.

What happens with an s-trap is when another fixture (such as a toilet) is used, the water in the trap can get sucked down and allow sewer gases into the home. They are minor by nature, and just running water for a moment stops the gases.
