My 2014 BH 3570 has (4) roof vents. My main concern is an odor under the kitchen sink that is a 'real' problem. I've determined its the Vent Check valve under the sink. I believe, when the wind is just right, (and the wind was blowing pretty hard the last couple days), the valve somehow gets stuck open and allows back draft. I've decided to explore the Cyclone Vent, so yesterday I crawled up on the roof and (hmmmm) I've got (4) roof vents. (2 about one foot apart mid coach, above the shower area, (1) right above the toilet, and (1) all the way forward on the nose, above the W/D area.
Before I go buy the Cyclone Vent and hassle with the installation, I'm going to buy another Vent Check valve and replace the one under the kitchen sink. I find it hard to believe that the valve is worn out or defective since this is a new coach, but that would be an easier changeout than roof vents.
Question: How do I determine which roof vent ties into the Kitchen holding tank. And is it possible, more than one roof vent is used for the kitchen tank? see picture...........
