Reliance Combination Non-Return Isolating Valve 20mm Female BSP - NI701

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

Combination Non-Return Isolating Valves prevent the backfl ow 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.

  One piece unit for tidy, simple and economical installation

RMC Combination Non-Return Isolating Valves offer both non-return and isolating functions in a single valve.
