Got everything apart except the new 1/2 check valve installed two months ago. All air lines were dry as was the forward tank. The compressor runs fine after removing the air hose and that indicates to me CHECK VALVE or obstruction , but again and I can't get it apart. used plumbers putty when put in and I can't break it loose..I have superman coming over next week at $110 an hour and would like to avoid that and also running on 60lbs from my 12volt aux forever.... Any ideas that lead away from the check valve ? Any ideas on how to get this baby apart ?
