Water tank will not fill

[jasonoreilly]

Hi all,

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
Thanks
Jason

Check to see if the vent hose from the fresh water tank is not kinked. If air can not exit the tank, fresh water will not be able to go in.

Does your pump turn off or does it continues cycling? Also when you open the relief valve does the air come out and your pump turn back on?

noting noticeable but I guess I will have to remove the bottom panel to see if its kinked higher up

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?

Thanks for the replys
