Plumbing Q & A - Ask the Plumber
Question- "There is a foul sewer type odor in my basement and water leaking from the washer drain pipe. It pours water when the water is running from the sinks or toilet. Is my septic tank backed up? What should I do?"
Answer- In our opinion, your septic tank is full and needs to be pumped. We would recommend you calling your septic company to come out and pump your septic tank.
