I'll start by saying I'm new to this and any help would be great. I have a 27' Prowler TT. When I was out dry camping this week, I had a problem with the fresh water. I had about 3/4 tank of fresh and turned on the water heater and water pump. I went for a little walk while waiting for hot water. When I returned about 15 min later I had water shooting out of my city inlet. when I turned the pump off the water stopped. Anytime I turned the pump on out it came. There was no pressure inside. Any ideas???
