Hey Tom:
If it is a Thetford toilet, there is a replaceable gizmo called the "water
valve". It commonly splits when the water supply line leading to it
freezes. I got one directly from Thetford.
So if you have a Thetford Aqua-Magic unit it's called the Water Valve
Replacement Package. Was around twenty bucks in Feb 2000.
If it isn't a Thetford.......never mind.
