Application
If the pressure in a system is high, the 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 525040 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 arrester is maintenance free and can be
installed in any orientation.

The arrester should be installed close to the tap or valve minimising the
effect of the shock on the system.


Operating Principle

The water hammer arrester consists of a cylinder (1) divided into 2
chambers (2) and (3) by a piston with two ‘O’ ring seals (4).
The closed chamber (2) acts as a damper due to the compressibility of
the air trapped inside.
The open chamber (3) is connected directly to the system and is filled
with water.
When a pressure surge occurs, the force from the spring and the
compression of the air counteracts the thrust on the piston allowing a
small change in volume which absorbs the excess pressure.
