Kitchen sink gurgles and smells when washing machine runs
Every time our washing machine hits the drain cycle, our kitchen sink gurgles and begins to smell of sewer gas terribly. We were told it was probably due to a clogged vent. My husband went into the attic and checked for clogs. He did find a cap on the pipe, which he removed - and the sink didn't gurgle for a couple of loads - but now it's back at it... just as bad as before. He's checked the pipe again, and can see clear down to the bend in the pipe. He also replaced the Stutor vent under the sink. Any ideas on what this could be?
