Hi all, Trying to figure out this odd occurrence with our kitchen sink recently. So not all the time, but maybe 10% of the time we do a load of laundry, our kitchen sink will gurgle, sometimes with water coming up, while our washing machine runs. The water goes back down immediately and never rises more than an inch or two. However, the water smells sewagey. Any idea what could be the issue? I've seen online suggestions of perhaps a venting issue near the sink, a clog in the washing machine's drain line, and others. Willing to try all reasonable fixes before having to pay big money for a plumber. Thanks.
