Gate Valves

[sfedeli3]

Hi Curt,

Glad you found it. I'd agree- it seems to be for isolating the water heater in
the event of a blowout in the heat exchanger or if you are working on the
heater. My front dash heat behaves the same way- even with the dash switch off,
it still gets warm. I have to turn off the two valves on the top and bottom of
the engine water pump to keep the queen happy in summer.
