The Plumbright Pump Valve Ball Type (1-1/2 inch x 22mm) is designed for professional plumbers and DIY enthusiasts who need a reliable way to isolate circulation pumps in residential or commercial heating systems. It provides the essential benefit of allowing pump maintenance or replacement without draining the entire plumbing circuit, though its specific sizing requires careful measurement of your existing piping before purchase.

This valve is specifically engineered for circulation pumps in heating circuits and may not be certified for potable water systems.
You will need a pair of adjustable wrenches or pipe wrenches to secure the compression fittings and the threaded connection.
Always check your package contents, but typically you will need to provide appropriate pump flange gaskets for the threaded side.
Yes, ball valves are generally bi-directional, but ensure the lever is accessible for future operation.
The valve is designed for standard heating circuit pressures; consult the packaging technical data for exact PSI/bar limits.
Ensure the pipe is cut squarely, the olive is not deformed, and tighten the compression nut an additional quarter turn.
Check for mineral buildup around the valve stem and consider flushing the system or gently working the handle back and forth.
Verify the valve is fully in the closed position and ensure there is no internal damage to the ball mechanism from debris.
To install, ensure the heating system is depressurized and drained to the level of the valve. Use appropriate pipe wrenches to tighten the compression nut onto the 22mm pipe, ensuring the olive is seated correctly to prevent leaks. The 1-1/2 inch threaded side should be connected to the pump flange using a suitable gasket or sealant. For maintenance, cycle the valve handle once or twice a year to ensure the ball seat remains clear of debris and mineral deposits. Regularly inspect the compression joints for any signs of weeping or moisture.
