If a system has a high operating pressure, water when flowing has a greater momentum which when brought to a sudden halt, will create a shock effect causing pipes to shudder and vibrate. This is normally caused by the rapid closure of lever operated taps or valves, solenoid valves or valves in dish washers and washing machines. The Altecnic pneumatic shock arrester or water hammer arrester is designed for a single outlet, such as a tap or washing machine, or a small group of services, such as a bathroom supplied via a manifold. The vibration caused by water hammer is not only annoying but eventually can result in split or cracked pipe fittings, especially at joints. The Altecnic water hammer arresters are maintenance free and can be installed in any orientation. The arresters should be installed close to the tap or valve minimising the effect of the shock on the system. The water hammer arresters are suitable for use in coastal environments and with brackish water due to their stainless steel construction.
