Troubleshooting

Solder fails to flow into the joint

Check that the pipe and fitting were cleaned thoroughly and that enough heat is being applied evenly around the circumference.

Joint leaks after installation

Clean the joint, re-apply flux, and reheat to draw in more solder. If the leak persists, the fitting may need to be cut out and replaced.

Pros and Cons

Pros

  • High-quality copper construction for long-term durability
  • Certified for both water and gas system usage
  • Widely recognized WRAS approval for potable water safety
  • Reliable, permanent connection when soldered correctly

Cons

  • Requires professional-grade soldering tools and experience
  • Not intended for demountable or temporary plumbing configurations
  • Requires careful preparation of pipe surfaces for a successful seal

Setup, Compatibility & Care

To ensure a successful installation, follow these professional practices:

  1. Preparation: Cut the 28mm copper pipe cleanly using a pipe cutter to ensure the ends are burr-free and square.
  2. Cleaning: Use an abrasive pad or wire wool to clean the outside of the pipe and the inside of the coupling until they are bright and free of oxidation.
  3. Fluxing: Apply a thin layer of suitable plumbing flux to the cleaned areas to prevent oxidation during heating and to aid solder flow.
  4. Heating: Apply a blowtorch flame evenly around the fitting. Once the flux bubbles, touch the solder wire to the edge of the coupling; capillary action will pull the solder into the joint.
  5. Cooling: Allow the joint to cool naturally before applying pressure to the system. Do not shock-cool with water.

Always ensure your work environment is properly ventilated when soldering and verify that all local building regulations regarding gas or water installations are strictly followed.
