pre April 2011 Ideal for Vortex Pro Combi 28mm

The Grant isolation valve sits underneath the heating appliance and enables the user to change the flow of water and gas into the central heating system. These also allow you to cut off the supply to the boiler if there is a leak or emergency. The Grant Non-Return Valve 28mm functions as a one-way valve, allowing fluid flow in one direction only to prevent backflow in heating and plumbing systems. It helps maintain system efficiency, ensuring optimal performance and preventing potential damage or inefficiencies. The 28mm size indicates its compatibility with plumbing systems with 28mm diameter pipes.
