0voteA: The Zurn Diaphragm Part Number 55885-3 is a generic number that Zurn stamps on their parts for their reference at the factory. Unfortunately this number does not direct you to the replacement Diaphragm that you will need. To find the correct replacement Diaphragm kit for your AquaVantage Flush Valve, you will need to determine the GPF (Gallons Per Flush). You can find the GPF a couple different ways- 1. Zurn stamps suffixes on the top Chrome Cap of the Flush Valve to specify the GPF - WS1 (1.6 GPF) or WS (3.5 GPF). 2. You can look on your porcelain fixture to see if there is a GPF stamped there; this is typically located near the manufacturer brand name. 3. If your toilet was installed prior to 1994 it's most likely that you have a 3.5 GPF. It it was installed post 1994 it's most likely that you have a 1.6 GPF.
