Part: VALVE — LEAKING (FWD HEATER)
FOUND WHILE COMPLYING WITH AD. ON THIS ASSEMBLY, IT CAN BE SEEN THAT THE RED RUBBER VALVE DIAPHRAGM IS VISIBLE ON 3 SIDES ONLY. THE (IN) SIDE OF THE VALVE SHOWS THE DIAPHRAGM TO BE RECESSED PAST THE SEAL AREA OF THE CASTING. EITHER THE DIAPHRAGM WAS ASSEMBLED INCORRECTLY OR THE FASTENERS THROUGH THE VALVE BODY WERE OVER-TORQUED, MISSHAPING THE ADJUSTMENT CAP. CAP APPEARS TO BE WARPED, WHICH DOES NOT ALLOW DIAPHRAGM RUBBER TO SEAL.
