Tower Mini Expansion Vessel Shock Arrestor – 1/2″ BSP (SA1/2)
The Tower Mini Expansion Vessel Shock Arrestor is designed to protect plumbing systems and connected appliances from the damaging effects of water hammer, which occurs when water flow is suddenly stopped.

The unit is pre-charged to between 3 and 3.5 bar, allowing it to react quickly to pressure fluctuations within the system. It connects via a standard 1/2″ BSP fitting and can be installed vertically or horizontally, offering flexibility to suit different pipe layouts and installation requirements.
Manufactured for use with potable water, the Tower SA1/2 Shock Arrestor is WRAS approved, confirming its suitability for drinking water systems and compliance with UK water regulations. Its compact dimensions, measuring 110mm in height and 78mm in diameter, make it easy to integrate discreetly into existing pipework without compromising system aesthetics.
