Dump Valve Rebuild?

[Pete Masterson]

The aux compressor is a 12v and appears to be the same one that's
listed as an option on the Microphor web site. The compressor doesn't
kick on very often since it takes a lot of flushes to get from 90PSI
down to 65 PSI when the compressor comes on. It appears to hold
pressure fairly well so it doesn't kick on in semi-storage except
every few days. (Coach in front of the house.)

I don't know if there's any air lines currently connected between the
aux tank and the main air system. Even if the aux compressor went on
while underway, I doubt I'd be aware of it. It's pretty quiet. I've
occasionally heard it from outside the coach while working on other
stuff.
