Abstract
The flush valve adapter (32) has a tubular body with a lower threaded section (36) which engages a connection ring (70) permanently mounted to an upper section of jetway (72). A seal is created between the tank (10), flush valve adapter (32) and jetway (72). The adapter (32) has an upper threaded section (40) which engages a bottom threaded end (30) of a standard flush valve. A coaxially spaced sealing ring section (48) has a groove (62) that seats an O-ring (64) that seals against the bottom section (30) of the flush valve to create a seal therebetween. A lock nut (78) is also threaded onto section (30) and abuts against top shoulder (41) of the adapter (32) to lock the flush valve into place onto the adapter member (32).
