ABSTRACT:
A seamless water hammer arrester is formed of an elongate chamber with an entirely seamless upper closed end and a lower end connectable to a water pipe. A piston is emplaced in the chamber and is movable up and down therein to dampen water hammer. The piston defines an upper chamber portion in the chamber which has a super atmospheric charge of gas providing a downward pressure on the piston. The piston is of a liquid and gas impervious, lightweight synthetic material and has at least three O-ring seals therearound to maintain a substantially leak free separation of the upper and lower chamber portions. The piston is preferably domed to accord to the shape of the chamber upper end and hollow to collect sediment when used in a upside down orientation.
