Product Information
Full details
The Plumbright Pump Valve Gate (Z21622) is an essential component designed for professional plumbers and DIY enthusiasts working on domestic heating and circulation systems. It provides a secure, reliable connection between circulation pumps and 22mm copper pipework, allowing for easy isolation during system maintenance. While it offers excellent durability and flow control, it is specifically engineered for standard 22mm copper setups and requires correct sizing to ensure a watertight seal.

Can this valve be used for cold water systems?
Yes, it is suitable for domestic water circulation, including cold water heating systems.
Does this come with washers?
Please verify your specific package contents, though it is recommended to use fresh plumbing washers during any new installation.
What is the primary function of this gate valve?
Its primary function is to isolate the pump from the rest of the heating circuit to allow for maintenance or replacement.
How often should I check the valve?
It is good practice to check the valve for any signs of seepage during your annual heating system service.
Troubleshooting
Valve leaking at the nut connection
Ensure the union nut is tightened properly; if leaking persists, inspect the internal washer for damage and replace if necessary.
Valve handle is difficult to turn
Apply a small amount of silicone-based lubricant to the valve stem and gently work it back and forth; do not use excessive force.
Pros and Cons
Pros
- High durability for long-term reliability
- Simplifies pump maintenance and replacement
- Ensures secure seal between pump and copper pipe
- Resistant to typical domestic heating system corrosion
Cons
- Limited to 22mm pipework compatibility
- Requires professional-grade plumbing tools for installation
- Not suitable for use with plastic piping systems
Setup, Compatibility & Care
To install, ensure the 22mm copper pipe ends are clean, deburred, and free from debris. Use appropriate plumbing sealants or washers as required by local standards to ensure a pressure-tight connection. Always verify that the pump orientation matches the flow direction indicated on the valve body. For long-term care, periodically exercise the valve handle (open and close it) at least once every six months to prevent the internal mechanism from seizing due to mineral deposits. If the system remains idle for long periods, keep the valve in the fully open or fully closed position to protect the internal seals.
