Ok gang, I'm getting to be a regular here but I need your help again. After a week of using the campground water through the CITY water fill, I unhooked that hose and then using the FRESH water fill, I filled my fresh water tank for the trip home. In a few minutes I noticed that every 60-70 seconds my water pump would come on for a second or two. I couldn't find anything that would indicate a leak inside, but on the outside water was trickling from the CITY water fill. I tried bleeding all the water lines and that seemed to help, but when I got home two days later water was still leaking from the city water port.
Suspecting I had accidentally created a siphon somehow, I drained all the fresh water and of course the trickle stopped. Now however, I've begun to refill (maybe 20 gallons) through the fresh water fill and I'm hearing the pump kick on again every 60 seconds again. I checked outside and water again is trickling from the city water fill. What the heck is going on???
