Venting issue with plumbing
Almost a year ago, we had a new modular home brought in. It's a 16x80 sitting on a full basement. This home has given us a lot of problems but here I only want to discuss the vent issue. Each time the washing machine drains, we hear the gurgling in the kitchen sink. The piping distance from the sink to the WM drain is approx. 16ft, with two elbows. The dealer has had a plumber (same one that installed the plumbing) in, he's failed each time. I talked to the dealer recently and they will be coming out to do some fixing/repairs, etc in a couple weeks. They don't have a clue what to do about the gurgling. So here I am, does anyone know how to fix this? I would be grateful because I don't want them doing a hodge podge fix. Thanks.
