Having bad odors enter your home is unpleasant and potentially embarrassing. If you detect a sewer-like odor emanating from your drains, it’s something you will want eliminated as soon as possible. Sometimes the fix is simple. At other times, it will require calling for plumbers to resolve the trouble.

Here are some reasons for those bad drain odors. For any assistance you need with plumbing in Wayne, PA, contact Carney Plumbing Heating & Cooling. We offer same-day service, satisfaction guaranteed.

Reasons for bad-smelling drains

  • Dry p-trap: This is the simplest problem, and easy to fix. 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 the drainpipe underneath the sink. 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 (for example, in an unused guest bedroom), this is probably the reason for the smell. The solution is to pour water down the sink to restore the plug against the sewer gas. Try to regularly run water down sinks that don’t see much use.
  • 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 basement or foundations.
  • Venting problems: Along with the p-trap, your plumbing probably has another method of preventing sewer gas from entering your house: venting pipes. 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, and this will force the sewer gases back down and up through your drains. Don’t try to clear the roof yourself; call for assistance.

A dry p-trap is an easy fix, but sewer line breaks and blocked vents are work for professionals. If you can’t stop the problems with your drains using simple methods, you will need to call for expert plumbing in Wayne, PA.
