over pressure ruptured radiator valve
I have a Burnham Independence IN4 that has a flicky Honeywell Presstrol since it was installed. Every year I would have to adjust the adjustment screw a little or it will not cutoff. This year the Presstrol failed and the pressure was so high the it ruptured one of the radiator value, see picture. The 0 - 30 PSI gauge is damage and it is no longer accurate and the relief valve failed to go off.
Some one please recommend a reliable Presstrol.
