Cherokee Grey Wolf 23 DBH pump won't shut off?
I'm a newby, I have a Forest River Grey Wolf 23 DBH, 2016 in very good condition. Problem, when I plug the power into 110 v in my house and all of the panel breaker switches are off, I hear a noise coming from beneath the rear bunk beds. When I lift the mattress up and look under it it appear to be a pump because it has plumbing lines. The pump seems to be running. question: is this a pump and why does it run when I'm not using any water?
