## Discrepancy

(CAN) BOTH INTERNAL FLAPPER VALVE APPEAR TO USE THE CHAMBER WALLS AS A MECHANICAL STOP, OVER YEARS OF USE, THE FLAPPER VALVES HAVE WORN A GROVE IN THE CHAMBER AND 1 SIDE HAS WORN THROUGH RESULTING IN 2 AIR LEAKS, CAUSING PRESSURIZATION ISSUES.  IT IS ALSO WORTHY TO NOTE THAT BOTH VALVES ARE ALSO DEFORMED DUE TO CONTACT WITH THE CHAMBER SIDES.
