FAQs

Is this stopcock suitable for hot water systems?

Yes, the brass construction is designed to withstand standard hot and cold water temperatures in domestic plumbing.

Does this come with installation washers?

The stopcock uses standard threaded connections, so you should ensure you have the appropriate connectors or fittings compatible with your specific pipe material.

Can I use this for gas lines?

No, this product is intended strictly for water supply systems and should not be used for gas piping.

What is the primary material used?

The unit is manufactured from high-quality, durable brass.

Is this for 1/2 inch or 3/4 inch pipes?

No, this specific model is designed exclusively for 1-inch pipework.

How often should I test the valve?

It is recommended to cycle the valve open and closed once or twice a year to ensure it remains functional in the event of an emergency.

Troubleshooting

Water leakage at the threaded connection

Unscrew the fitting, inspect the threads for damage, re-apply a fresh layer of PTFE tape, and tighten securely.

Valve handle is difficult to turn

The valve may have mineral deposits. Flush the line or apply a small amount of food-safe plumbing lubricant to the stem.

Valve is not fully shutting off flow

Check that the internal washer is properly seated or if debris is trapped within the valve body preventing a full seal.

Pros and Cons

Pros

  • High-grade brass material for long-term reliability
  • Standard 1-inch sizing for easy compatibility
  • Provides a positive, secure shut-off mechanism
  • Ideal for both residential and light commercial plumbing

Cons

  • Requires proper plumbing sealant or tape to prevent leaks
  • Heavier than plastic alternatives
  • Limited to 1-inch pipe configurations

Setup, Compatibility & Care

To install this stopcock, ensure your pipework is cut square and properly threaded to match the 1-inch connection. Apply appropriate plumber’s tape (PTFE tape) to the threads to ensure a leak-proof seal. Tighten using an adjustable wrench, taking care not to overtighten and crack the pipe or damage the brass threads. For maintenance, periodically turn the handle fully open and closed every few months to prevent mineral build-up and ensure the internal mechanism remains free-moving.
