Plumbright Compression Stop Cock - 28mm

BS1010 compliance indicates that the stopcock has been manufactured and tested to meet specific British Standards for water fittings, ensuring reliability, safety, and performance in water systems.

No, this stopcock is specifically designed for 28mm pipework only. Using it on a different pipe size will result in an improper seal and potential leaks.

You will need two wrenches (e.g., pipe wrenches or adjustable spanners) to hold the stopcock body and tighten the compression nut during installation.

DZR stands for Dezincification Resistant. It's a type of brass alloy that is treated to prevent the leaching of zinc from the material when exposed to water, making it more durable and resistant to corrosion, especially in hard water areas.

It is recommended to fully open and close the valve handle every 6 to 12 months. This helps to prevent the internal components from seizing due to inactivity or mineral buildup.

While the DZR brass is robust, this specific model's suitability for hot water should be confirmed with the manufacturer's specifications. Typically, stopcocks designed for general use are compatible with standard hot water temperatures, but check for any specific ratings if intended for high-temperature applications.

Ensure the pipe is clean, free from damage, and fully inserted. Tighten the compression nut evenly. If the leak persists, the olive may need replacing, or the pipe may be damaged.

Operate the valve back and forth a few times. If it remains stiff, a small amount of appropriate lubricant might help, but avoid getting lubricant inside the water pathway. Ensure no debris is obstructing the valve mechanism. If severe, replacement may be necessary.

Check for any blockages within the pipework leading to or from the stopcock. Ensure the valve is fully open. Inspect the valve seat for debris. If the issue persists, the stopcock may be faulty and require replacement.
