3-Bar Pressure Relief Valve (MPCBS123)

This Grant pressure relief valve is the direct replacement for the MPCBS50X. It is now 3-bar instead of 2.5 and comes with no gauge port.

This is suitable for:

The Combi V3 external, the Vortex Pro external and Vortex Eco.

If your pressure relief valve is leaking, this is normally down to poor system water or failed expansion vessels, so before you fit, please check.
