FAQs

What pipe size does the Pegler 59 support?

This model is specifically designed for 15mm plumbing pipe.

Is this stopcock lead-free?

The Pegler 59 is constructed from high-quality brass meeting relevant plumbing standards for safe domestic water use.

Can this be used on hot water pipes?

Yes, this brass stopcock is suitable for both hot and cold water systems.

Does it come with compression nuts and olives?

Typically, you should ensure you have the correct size compression fittings available for your specific pipe installation.

How often should I operate the stopcock?

It is recommended to cycle (open and close) the valve every six months to ensure the internal seal remains free and functional.

Troubleshooting

Valve leaking at the connection point

Tighten the compression nut slightly. If it continues to leak, inspect the olive for damage and replace it if necessary.

Valve handle is difficult to turn

Check for sediment buildup around the valve stem. A small amount of food-safe silicone grease can help lubricate the threads.

Water continues to flow when valve is fully closed

The internal washer may have degraded. This typically requires replacing the internal valve jumper or the valve unit itself.

Pros and Cons

Pros

  • High-grade brass construction for long-term reliability
  • Manufactured to strict BS1010 standards
  • Simple manual operation for immediate water isolation
  • Compatible with standard 15mm copper piping

Cons

  • Requires professional plumbing tools for installation
  • Manual valve operation may be stiff for those with limited hand strength
  • Not suitable for use with non-standard pipe diameters without adapters

Setup, Compatibility & Care

To install the Pegler 59, ensure the main water supply is drained before cutting the pipe. Use appropriate compression fittings to connect the stopcock, ensuring the flow direction arrow on the valve body aligns with the water movement. Always tighten compression nuts carefully to avoid damaging the olives. For maintenance, periodically open and close the valve to prevent mineral deposit buildup, which can cause the internal mechanism to seize. If the valve feels stiff, do not force it; apply a food-safe silicone lubricant to the stem if necessary.
