Update on this. I think McNeely reported getting a replacement front
heater valve from NAPA, so I looked into that. only $6, and they had
it at my local store the next day for pickup. I did the "blow
through test" and no air went through it. So I put it in place of
cpvc prototype mentioned below. It will not flow as much coolant
when open as my cpvc version but at least I know it's compatible with
the coolant. Seems to shut off fully, and it's getting to that time
of year when I want that.
