Water Fill Value Problem (PT-40)

[Curt Sprenger]

Kevin,

I've experience the same issue. Sounds like the Sporlan Valve, located
near the water tank. The valve is controlled by the "fill tank" switch.
Our coach has the walk-around bed, water tank is under the bed, the
sporlan valve is on the drivers side of the water tank.

Remove the four screws around the electro-magnet. Remove the rubber
diaphragm. Using a screw driver, stuff a small rag into the opening to
stop the water flow. Clean out any foreign matter, usually white stuff.
Carefully remove any foreign matter from the diaphragm. Reassemble and
all should be good.

One small piece of crud will stop these valves from working.

About a 20 minute project.
