Valves & Plumbing Control Valves Combination Non Return Valves

Combination Non Return Valves

RMC Combination Non-Return Isolating Valves combine the mandatory functions of isolating valve and non-return valve for the installation of pressurised water heaters.

Combination Non-Return Isolating Valves prevent the backflow of water from a water heater to the mains line. This serves the dual purpose of protecting the mains supply from contamination, and the loss of water that has already been heated. The isolating valve component is useful as a means of controlling inlet water supply to unvented storage water heaters.

RMC Combination Non-Return Isolating Valves are available in 15 mm and 20 mm configurations.
