Well for a update I did fill fresh water tank last night and ran pump to fill hot water heater and all lines and pumped kicked off lick normal and it sat for atleast 15-20 minutes and never came back on till I cracked a faucet. But I did go out today and took a ice pick and put a 1/8 hole in belly were I thought it was full of water and nothing so I am really thinking it is just the weight of the rubber making it feel like it has water. I am going to cheeck some more over the weekend but I guess I am good to keep working to get camping soon.
