• WRAS Approved. Potable Water Shock Arrestor. Potable water shock arrestors are designed to prevent water hammer. Water hammer is ca***d by shock waves running through the water system which create noise or in severe cases pipe movement within a system, reverberations are a series of shock waves in quick succession. The pressure wave in such circumstances can be up to three times greater than the standing pressure. Water hammer occurs when the flow rate is suddenly changed. The solution is to fit a shock arrestor directly before the affected fitting. The shock arrestor is a mini expansion vessel, which works by absorbing the shock wave from the fitting so it does not travel through the system and ca*** a noise, the closer the shock arrestor is installed to the fitting the better. Maximum temperature: 99ﾟC Minimum temperature: -10ﾟC Pre-set Pressure: 5 bar Maximum working pressure: 15 bar Stainless Steel Flange Dimensions: 105 (H) x 65 diameter
