If you have water hammering and you have installed shock absorbers and the problem comes back, you may need to check the pressure of the water. If it is 80 psi or close to 80, you need a pressure reducing valve. Cities do allow 80 psi in a home, but it is really too high. Pressure should be no greater than 65 psi to prevent water hammering. Water hammering is created by fast-closing-cartridge types of faucets and solenoid valves on dishwashers and washers.
Water hammer can be eliminated from the cartridge-type faucets by replacing them with compression-style faucets (faucets that open and close by the stem rising in a threaded cylinder).
