The McAlpine CONVALVE-125P Convalve Non-Return Valve is designed for plumbers and homeowners needing to prevent backflow in pressurized hot water systems. Its key benefit is protecting the system from overpressure and overheating by ensuring water flows in only one direction. A potential caveat is its specific ¼" connection size, requiring compatible plumbing.

A non-return valve, like the CONVALVE-125P, prevents water from flowing backward into the hot water cylinder. This is particularly important for pressure-relief discharge lines to ensure safety and prevent system damage.
The valve has a ¼" plain tail inlet and a ¼" universal outlet.
It is specifically designed for pressurized hot water systems and requires ¼" connections. It is not intended for general-purpose plumbing applications.
Under normal operating conditions, the McAlpine CONVALVE-125P is designed to be maintenance-free. Periodic visual inspection for leaks or damage is recommended.
The valve should be installed in the discharge line of the pressure relief valve. Ensure water can only flow out of the system through the valve, not back in.
The valve is constructed of high-quality materials designed for reliable and long-lasting performance in plumbing applications.
Ensure connections are tight and properly sealed. Check for any damage to the valve threads or the connecting pipes.
This may indicate debris or internal damage. If accessible, inspect for obstructions. Otherwise, replacement may be necessary.
Verify that the non-return valve is installed in the correct orientation and that other system components, like the pressure relief valve itself, are functioning correctly.
