Air Valve Leak

BTW, the PIAB vacuum pump mounted on the manifold does exhaust quite a bit of air while doing it's job. It's a no-moving part, simple device that uses compressed air to draw a vacuum (there's a steady hissing sound), so it's not unusual to hear the 12V compressor run while sucking air out of the seal.

Thanks Al!

David,

I did call HWH this morning but was not able to speak to any parts person. Aperson answered and said she was taking messages and someone would have to call me back later. They're evidentally overloaded.

The present manifold also blows air out the end of the manifold through the valve with the .030 orfice located after the regulator. This happens when the Schrader solenoid valve is powered. I think that valve is powered by the slide operator's key.

I would just replace that valve (it appears to have the spool stuck in the middle) if I could just find a replacement. I would disassembly the valve but I haven't figured out how to get it apart yet. I just have had no luck in finding one tho. Then later replace all with the PIAD manifold.

I'm trying to get the coach to the shop to check the brakes,(poping noise on right front wheel when brakes are depressed) replace the shocks and remove that anti-sway bar but the valve is leaking so bad that I had to disconnect it and plug the air line going to it. The air system is very tight otherwise with that done. I aired the coach up and turned on the aux a/c to check for other leaks. The aux a/c only came on once for about 3 minutes in 24 hours. So I'm happy about that.

Chuck
