The lady in the park here "Riverbend" ask me why her auxilary compressor ran every 15 min obviously an air leak. Her bed will not raise and she says the line has been plugged under a cabinet guess that's the first place to look. Question for the group, are there any valves that close off to certain features such as pocket doors etc or is it plumbed straight from the air tank. she has not received her manual from Prevost nor has she gone online to try to pull it up. 1993 H-3 40 Thanks Gary,
