Reasons for Bad-Smelling Drains

  • Dry p-trap: “P-trap” is the name for the curved pipe section directly beneath your sink. The shape of the pipe is designed to trap a plug of water between the down pipe sections and the drain opening, and this prevents rising sewer gas from escaping up into the house. However, if a sink is not used for a long stretches (this can often occur in the bathrooms of guest houses) the water in the p-trap will evaporate and allow noxious gas to get through. This is easy to fix: run water down the drain for a few minutes to restore the water level in the p-trap.
  • Blocked drain vents: To prevent a build-up of sewer gas pressure inside pipes, drain vents move the gas up to openings on the roof of your house. Should these vents become blocked because of debris or animal nests, it will force the sewer gas back down the pipes; the pressure will be sufficient to push the gas through the water in the p-traps. If you hear a gurgling sound in your drains along with the bad smells, then clogged vents are probably the cause of the problem. Don’t climb up to the roof to unblock the vents yourself! Stay safe and call for professional assistance.
  • Sewer line issues: This is the most serious of all possible causes for bad-smelling drain. Should the sewer line that takes the wastewater from your home out to the municipal sewer system in the street or to your septic tank become blocked from root infiltration or burst, it will start to back up sewage into your drains. If the bad smells are coming from multiple drains, it is likely that the sewer line is responsible. You need to call for help immediately, since this problem can lead to sewage flooding your basement or your home’s foundations.
