FAQs
What does 'DZR' mean?
DZR stands for Dezincification Resistant. This indicates the brass alloy is formulated to resist corrosion, particularly in hard water areas, ensuring a longer lifespan for the valve.
Can I use this stop cock for gas lines?
No, this stop cock is designed exclusively for water systems. It is not rated or safe for use with gas.
What is the maximum pressure this valve can handle?
The Plumbright Stop Cock is designed for standard domestic water pressures. For specific pressure ratings, please refer to the product packaging or manufacturer's technical data.
How often should I test the stop cock?
It is recommended to operate the lever at least once every six months to ensure it remains free-moving and functional.
What tools do I need to install this?
Basic plumbing tools are required, including pipe cutters, wrenches, and potentially a pipe vice. Sealant such as PTFE tape or pipe dope is also necessary.
Is this valve suitable for underground use?
This valve is intended for use within domestic plumbing systems. For underground applications, specialized valves designed for burial are typically required.
Troubleshooting
Valve is leaking after installation
Turn off the water supply. Check that the pipe connections are clean and properly sealed. Reapply sealant and tighten connections securely.
Lever is stiff or difficult to move
Ensure the water supply is turned off. Operate the lever gently to free it. If persistent, a small amount of lubricant may be applied to the spindle, or consult a professional plumber.
Water flow not fully stopped
Ensure the valve is fully in the closed position. Debris may be caught in the valve seat. If the issue persists, the valve may require servicing or replacement.
