Non-Return Valves

RMC High Temperature 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 15mm, 20mm and 25mm configurations, and conform to AS 1357.1-2009.
