Potable water tank

Hi, we have had an issue with our fresh water tank and pump. There are times when we cannot fill our tank with water because the water comes back at us. Full you think? Well we also try to run the pump to flush the water through and get nothing but air through the faucets. All are open! Just sputtering! Could there be an air lock? If so, how do I correct this issue. As well, when we open the valve to empty the tank, lots of water!

I would start by looking at the piping going from the fill point to the tank. Look for a sag in the fill line and also make sure the vent line doesn't have a sag in it either. Once you get to where you can fill the tank you shouldn't have a problem getting water to your faucets. If you are getting sputtering your pump is doing its job, just no water to the pump suction line yet.

We had a similar problem with our previous TT. After some investigation, it turned out to be a kink in the vent tube.

Thanks for your responses, as it turned out we had a kink in our hose, thus preventing us from filling. Happy trails!
