Mini Expansion Vessel also called Shock Arrestor complete with end feed Tee
Mini Expansion Vessel also known as Shock Arrestor complete with end feed Tee suitable for solder connection.
Recommended by several boiler manufacturers to reduce water hammer and protect your combi boiler by absorbing dangerous peaks in water pressure.
Particularly useful where a non-return valve and water meter is fitted to a property, as the electrically operated actuator can cause a momentary spike in water pressure.
Includes an end feed Tee, 15mm x 15mm x 1/2inch BSP female thread.
Installation instructions: Fit this on the potable water cold feed before it reaches your boiler so it can protect the fragile internal components from water pressure shock and resonance. Always use lead-free solder on potable water pipes, and secure the thread with PTFE tape or another suitable thread sealant.
