Problems with air dumping

[Bob Lawrence]

First want to thank Steve and Ralph who send me files of the various
air systems....thanks again, guys..will print them off for others we
meet on our travels that might have similar problems.

I found the solution to my problem.
Turns out the air switches are/were the problem. Pulled them out and
found that these valves have many mini o rings. Seems they fall apart
with age and the small pieces jam the air holes.
Replaced them with new and bigger air switches...problem solved.
Bus now dumps quicker and fills quicker as went to 1/4 in size
openings.

Thanks again to Steve and Ralph.

I know several have mentioned they have this occasional problem and I
think this is the reason.
