How to Remove and Prevent Floor Drain Odors | Roto-Rooter

Do you have a problem with smelly floor drains? Do you have a pest problem in the area around a floor drain? Proper maintenance can go a long way to preventing these issues, and it’s simpler than you might think.

Floor drains, much like the drains underneath your interior sinks, have a u-shaped pipe underneath them, called a P-trap. A P-trap serves a few different purposes, but the most important one for your floor drains to create a water barrier. This will prevent drain odors, and insect issues from the adjacent sewer system.

If you smell a funny stench or odor coming from your floor drain, it’s very likely your P-trap is dry. Simply pour a few gallons of water to re-establish the proper water barrier. You can add a small amount of vinegar to help remove any persistent odors.

If you need help cleaning or clearing a clogged floor drain, you might want to call in the experts. Visit and schedule an appointment 24/7/365.

  1. Thanks for this very useful video. I have just solved a foul smelling laundry room problem with a few bottles of water. Because it’s only an emergency floor drain in that room and not shared with anything else like the sinks, the trap was completely dry. Pretty sure I’ve just solved my cockroach problem as well (only place I could think they were getting in was the drains) 👍
