Re: back-up shut off valve for heater control valve

[tr6taylor@webtv.net (Sally or Dick Taylor)]

Bruce---I installed on of these valves many years ago. Yes, it's between
the head and the stock valve. All brass, and the cost was about $5 back
then. I'm pretty sure it's 1/2" pipe thread. Of course since I put this
in, the stock, diaphragmed heater valve has never failed!

I recall the TR3? has something similar, with no in-cockpit contol. If
so, this might fit the Six.
