  • Air leak

    Posted by Art on October 21, 2018 at 9:51 pm

    When I 1st got coach it leaked like a sieve rebuilt dryer replaced treadle valve and governor rebuilt head on compressor and it would hold air for ever, for some reason 1 1/2 years and 12000 miles it’s leaking down slowly on gauges all 3 evenly, Looking at air system I thought, what would let all 3 drop, The main tanks have check valves, so air goes in to wet tank from dryer then 2 lines from wet to front and rear main tanks via 1 way check valves and aux tank has pressure protection valve so where could it leak that would affect both main tanks? does compressor main line have a check from compressor to dryer? would treadle valve cause that?
