ABSTRACT:
A water hammer arrester comprises a cylindrical body housing a piston for free sliding reciprocal movement and a connector for connection to a water conduit system which carries water under pressure. An abutment-bumper combination is interposed between piston and connector to avoid the ping which would be produced is these two elements of the assembly were to collide during reciprocation of the piston.
