The McAlpine R28-NRV is a 0.75" overflow non-return valve engineered to prevent backflow and siphoning in domestic plumbing systems. Ideal for basin overflows, bath waste lines, and appliance connections, this valve maintains system integrity by allowing water to flow in one direction only. Constructed to BS 6465 standards, it delivers reliable performance in both new installations and retrofit applications. Essential for compliance-driven projects where backflow prevention is critical.
