Valves & Plumbing Control Valves Non Return Valves

Non Return Valves

RMC Non-Return 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.

Non-Return Valves are suitable for use in domestic and commercial water heater installations, and are rated for high temperature applications (up to 99° C).

RMC Combination Non-Return Valves are available in 15 mm, 20 mm and 25 mm configurations, and conform to AS1357.1-2009.
