Re: Heater valve modification

FWIW:

What's really crazy about this valve is the direction of the
water flow through it.  If the water does flow from the head to
the heater and back to the pump, the flow is trying to lift the
shut off valve off it's seat.  Why wasn't it made so the water
flow PUSHED the valve onto the seat?  A lighter spring could have
been used on the seal, it would take less pressure on the control
line to close it, etc.  Huh...  Inquiring minds want to know.
