Harmoni TRV Shut Off Valve

Harmoni TRV Shut Off Valve

Introducing the new innovative and patented solution which eliminates the need to drain a central heating system when disconnecting or repositioning a radiator. 

A truly innovative solution that saves you time, money, and is environmentally friendly as the rust inhibitor in your central heating system does not need to be flushed away into the drains.  A QR code comes with every pair and can be applied to the radiator or the valves which will advise the plumber that the heating system does not need to be drained and the radiator can be removed easily without water spillage.
