.  I have it plumbed to the radiator with a

cutoff valve. I would strongly suggest one as should a leak develop

this

would enable you to shut off the hot water.

Ed, you need TWO shut off valves if you expect to close off a break in

the

heater core.  One will stop the hot water from going through the core,

but

there is enough pressure in the system to force fluid out from the

socalled

suction side.

Excellent point, Bob.

    Unless you have a one way flow valve in the return line you would still
end up with hot water in the cockpit.  Well, I guess its a good thing I even
used stainless steel braided hose for that system, so hopefully no leaks.
