Abstract:
A water hammer arrester configured for connection with a plumbing system. The water hammer arrester has a cap assembly, a piston assembly, and a base assembly. The cap assembly receiving the piston assembly therein. The base assembly having a connector for connection with a plumbing fixture in the plumbing system.

Claim (Index 20):
A method of assembling a water hammer arrester, the water hammer arrester configured for connection with a plumbing system, the method comprising the following steps:\n providing a cap assembly, the cap assembly comprising a cap having an open first end and a closed second end, the cap defining an air chamber therein, the cap having a lower exterior sidewall and a lower interior sidewall adjacent the open first end, the lower interior sidewall comprising at least one retention portion extending inwards there-from, the at least one retention portion is formed in the cap assembly before a piston is inserted into the open first end of the cap assembly; providing a piston assembly, the piston assembly comprising the piston, the piston is configured for sliding movement within the air chamber as pressure in the connected plumbing system changes; providing a base assembly, the base assembly comprising a base having an open end configured for connection with the open first end of the cap and a connector for connection with a pluming fixture in the plumbing system, the first open end of the base defining an exterior chamber therein surrounded by an interior sidewall, wherein extending through the base is a passageway fluidly interconnecting the first open end with the connector, the exterior chamber configured for receiving therein the open first end; inserting the cap assembly, piston assembly, and base assembly into a high pressure chamber; pressurizing the high pressure chamber; inserting the piston into the open first end of the cap assembly and into the air chamber until the piston clears the retention portion thereby locking the piston inside the cap assembly; inserting the open first end of the cap assembly into the open end; and fixing the cap assembly to the base assembly.
