This week a customer 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?"

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
