    More issues 2006 Columbia . Air bags not going up due to air pressure . 2nd tank builds about 50 lbs and up to 100 psi if I sit there and rev it up . But does not go over that . No air leaks . Drains both tanks . Lots of water came out of both

    Bypass the Air dryer and if your problem is solved replace it

    Does the air governor pop indicating back pressure? If so check your main airline going to the air dryer

    How fast does your air drain from 130 to 100?

    Check the valve by your 5th wheel . That is what distributes the air to the bags
