Are Foul Odors from a Drain a Sign that I Need Sewer Repair?

The sewer line is the pipe that runs from your drains underneath your property to carry wastewater from your home into the municipal sewer. When there’s a problem with the sewer line that helps to evacuate sewage into the sewer, you’re responsible for handling any repairs up until your sewer line meets the sewer main. This means that, unfortunately, you’ll have to deal with finding a solution for the foul odors that sometimes go along with sewer repair.

A sewer line in need of repair will often, sadly, bring unpleasant smells along with it. But is this always the case? And are foul odors always a sign of a sewage line issue? We’ll address these questions on today’s guide to drainage problems and sewer repair in Lower Gwynedd.

Sometimes, odors are a sign that your sewer line has sprung a leak. However, if the leak is underneath your property, it’s unlikely that you’ll smell it in the drains. Rather, sewage will leak outside, possibly causing your yard to smell instead. If the leak occurs in a drain line behind the walls, an odor is likely to penetrate your home. If there is a major clog in your sewer line, sewage may backup into the drains, a probable source of unpleasant drain odors. Smells may also be contributed to sewer lines that are improperly vented, which means your plumber will have to install new vents.

Here’s something to ask yourself when you notice a smell from only one of the drains: when was the last time you used it? If it’s been a while since you’ve turned on the faucet or fixture that empties into that drain, there may be a very simple solution. Try simply running the water. The P-trap underneath a drain, the curved section of pipe that fills with water to prevent you from smelling the odors emitting deep from the sewer pipes, can dry out if left unused for a long time. Simply running the water can restore the amount of water necessary to block out the smell.
