If = the bellows is leaking down, double check that the two dump valves under = the valve cover are tightened properly. If it doesn=92t work at this point and passes the above tests, about the = only thing left is to insure the line to the atmosphere is flowing = freely. Good luck with it. If you must get it repaired, please post the issue = found by the repair shop as failure of the valve is rare. Hope the above helps.
