What Causes a Sewer Smell? | Roto-Rooter Blog

This week a customer in Houston asked the question, "What causes the kitchen sink to have a sewer smell when the dishwasher is running? Do I need to call a plumbing contractor to fix?"

When you smell sewer gas from the kitchen drain, it often means there is a blockage in the vent or the drain pipes inside the wall. If either of these are clogged, there is no place for the water to go without first forcing the air, which is combined with sewer gas, back into the room.

Call one of your local plumbing companies to diagnose the real issue. These types of plumbing problems should be left up to professionals who are familiar with residential plumbing
