Has anyone had problems with a Cumberland Model A-45 release valve?
I was flying on Sunday in about 58 degress F, humidity of 67% about 3000 ft.
As tank pressure increased, the release value should have tripped to keep it under control. It didn't. Fortunately, I noticed the problem quickly and was able to release pressure manually. But I'm concerned about future occurrences.
The unit is about 15 years old but has been well maintained. Could age be the problem?
