FAQs

Are these fittings suitable for gas lines?

Yes, Prima Plus endfeed fittings are designed to be robust enough for both water and gas installations, provided they are installed according to local building codes.

Do I need a special flux for these fittings?

Standard plumbing flux suitable for copper-to-copper connections is generally sufficient.

Can I reuse a fitting if I take it apart?

No. Once a soldered joint is broken, you should discard the old fitting and use a new one to ensure a secure, leak-proof seal.

What is the primary benefit of the kite mark?

The kite mark is a sign of third-party verification that the product meets the highest standards for quality, safety, and performance.

Is this coupling compatible with plastic pipe?

No, endfeed couplings are specifically designed for copper-to-copper connections. Do not use with plastic pipes.

Troubleshooting

Joint leaks after cooling

The joint likely has a 'cold' spot or insufficient solder. Clean the area, re-apply flux, and reheat until the solder flows correctly into the gap.

Solder won't flow into the joint

Check if the pipes were cleaned properly. Oxides on the copper prevent solder adhesion. Clean surfaces thoroughly and ensure enough heat is applied.

Pros and Cons

Pros

  • Meets rigorous EN 1254 manufacturing standards
  • WRAS approved for potable water safety
  • Kite marked for verified quality and consistency
  • High-grade copper ensures long-term joint integrity
  • Compatible with standard copper piping systems

Cons

  • Requires professional-grade soldering tools
  • Installation demands a level of manual dexterity and experience
  • Heat exposure can damage nearby sensitive materials

Setup, Compatibility & Care

Installation requires a blowtorch, lead-free solder, and flux. First, deburr the ends of your 54mm copper pipe to ensure a smooth insertion into the coupling. Clean both the exterior of the pipe and the interior of the fitting with a wire brush or abrasive cloth. Apply a thin, even coat of flux to both surfaces, join them together, and apply heat uniformly until the solder wicks around the circumference of the fitting. Allow the connection to cool naturally without moving it to prevent stress fractures. Inspect the joint under pressure once cool before concealing it behind walls or floors. These fittings require no special maintenance once installed correctly, provided they are kept free from external corrosive chemicals.
