m16ty Posted March 15, 2016 Share Posted March 15, 2016 Been there, done that. Usually the treadle is a real pain to change and then you find out that wasn't the problem. I don't recall what the solution was but you have another valve sticking somewhere causing it to back feed through the treadle valve.

85snowdog Posted March 15, 2016 Share Posted March 15, 2016 You could check the quick release valves. That is normally where the air is exhausted from. 1 Quote Keith Link to comment https://www.bigmacktrucks.com/topic/44344-air-leaking-from-treadle-valve-exaust-line/#findComment-327529 Share on other sites More sharing options...
Mike Posted March 16, 2016 Share Posted March 16, 2016 I hope it is coming from the treadle valve and not from under the seat. I always have air leaking from somewhere when I's go to sit's down.
