New to RV life and I bought a 2010 Sierra 355QBQ for myself and kids.
My problem is that I cannot seem to get the water tank to fill. It has one connection point and the valve to switch between city and gravity. When I connect to city all works well. When I connect to gravity the tank never reaches more that 1/3 full and even when I leave it connected for an hour nothing comes out of the overflow. I did open all the sink faucets in case it was airlocked. The only water outlet i didn't open was the installed washer/dryer.
Has anyone experienced this problem before??
Appreciate any advice
I believe the pump turns off although I have been mostly not using it and just using the mains supply so I will have to check. Regarding the relief valve - I don't know anything about that - where would it be located?
