Why Does My Drain Smell Bad?

If you only notice a sewage smell coming from one of your drains, the trouble might be a dry p-trap. The p-trap is the curved section of drainpipe under the sink and it is responsible for capturing water to form a plug against sewer gases coming back up the pipe. If the bad-smelling sink is one that hasn’t been used in a while, or a seldom-used sink (like an empty guest bathroom) this is probably the reason for the smell. In this case, you can alleviate the bad drain smell by routinely running water through your drain.
Sewer Line Issues
If the odors are coming up from sinks all around the house, the trouble might be a break or block in the sewer line that carries wastewater out to the municipal sewer system.
The odors will probably be accompanied by clogs and gurgling sounds from the drains. This is a major repair issue that needs professionals to take care of right away, since it can lead to sewage flooding into your home’s foundations and even the basement. If you notice the smell is accompanied by gurgling sounds and clogs, you know this is the answer.
Venting Pipe Problems
These pipes remove back-flowing sewer gases and run them up to the roof of the house. They can become clogged from debris, animal nests, and snow. These clogs will force the sewer gases back down and up through your drains. Don’t try to clear the roof yourself; call for assistance.
Sometimes the smell may only be coming from one drain. If flushing water down the drain didn’t loosen the p-trap and clear the smell, it’s possibly a venting pipe problem. Venting pipes are another method plumbing systems use to keep sewer gas from entering the house. Venting pipes take back-flowing gasses to the roof, where they’re safely released.
However, these pipes can become clogged or filled with debris, which forces the sewer gasses back through your indoor pipes and drains. If you noticed slowly draining water or gurgling sounds leading up to the smell, this is likely the problem. It will need to be cleared with a plumbing auger if the vent pipe is clogged.
Bad odors in the house are unfortunate, and the smell of sewage coming from an otherwise clean sink could be uncomfortable for any homeowner. If your drains and pipes are causing smelling problems, don’t hesitate to book an appointment with our professionals at Butler Plumbing today.
