Supreme cPVC NON RETURN VALVE (NRV)

The Non Return Valve (NRV) is a flow-control valve from the Supreme Lifeline C-PVC Hot & Cold Water System, built to integrate seamlessly with Supreme Lifeline CPVC pipework for both hot and cold water lines. It is designed to give reliable, leak-free control of water flow — whether for isolating a section of plumbing, preventing backflow, or filtering debris — while resisting the corrosion and scaling common to metal alternatives.

• Q: Can this valve be used on hot water lines?
A: Yes, its CPVC/CPVC-compatible construction is rated for both hot and cold water service in line with the Supreme Lifeline system.
• Q: How is it connected to the pipework?
A: It connects using solvent-weld CPVC ends and/or threaded connections depending on the size and model; check the product's connection type before installation.
• Q: Does the valve need periodic maintenance?
A: Routine operation (opening/closing periodically) is recommended to keep the mechanism free-moving; avoid over-tightening threaded connections, and inspect seals periodically in hard-water areas.
