Water Issue?

[John Mann]

I am trying to leave on a trip and I was filling the bus with water as
normal but when I flip the fill switch to off it doesn't close it just
continues to fill the water tank. Unfortunantly now my water pump will
not prime nor can I use the city water hookup since it just fills and
overflows the water tank. I assume it is the Sporlan valve maybe that
is stuck any help on how to fix, repair etc this valve or any tricks
to get it to close so I can go on my trip and then repair when I get back?
Appreciate any help!
