Product Information

Full details

The Prima Plus Solder Ring Fitting Reducer is designed for professional plumbers and experienced DIYers who need to transition between different pipe diameters efficiently. Its primary benefit is the pre-integrated solder ring, which significantly reduces installation time by removing the requirement for manual solder application. While this simplifies the process, it requires precise heat application to ensure the integrated solder flows correctly throughout the joint for a leak-free seal.

FAQs

Is this fitting suitable for gas lines?

Yes, the Prima Plus Solder Ring range is suitable for both water and gas systems.

Can I use this for drinking water?

Yes, the product is fully WRAS approved, making it safe for use in potable water applications.

Do I need to add extra solder?

No, the integrated solder ring provides the necessary amount of solder for a standard joint, eliminating the need for extra wire.

What standards does this fitting meet?

It is manufactured to the EN 1254 standard and carries the British Kite mark.

Can this be used with plastic pipes?

No, this is a solder-based copper fitting and is intended for use with copper piping only.

Troubleshooting

Solder does not flow into the joint

Ensure the pipe has been properly cleaned and fluxed. Re-apply heat evenly around the fitting to encourage capillary action.

Joint leaks after cooling

Allow the fitting to cool completely, then inspect for voids. You may need to clean the joint and re-solder or replace the fitting if the pipe was damaged.

Fitting becomes loose during heating

Use pipe clips or a jig to ensure the 15mm and 8mm pipes are held perfectly aligned while the solder is in a molten state.

Pros and Cons

Pros

  • Saves significant time on site by eliminating manual solder application
  • High-quality copper construction ensures long-term reliability
  • WRAS approval provides peace of mind for drinking water systems
  • Compact design is ideal for tight spaces where maneuverability is limited
  • Consistent, reliable performance meeting British standards

Cons

  • Requires careful temperature control to avoid overheating or uneven flow
  • Limited to specific 15mm to 8mm size transitions
  • Copper fittings require basic soldering skills to ensure a perfect joint

Setup, Compatibility & Care

For optimal results, ensure that both the pipe and the interior of the fitting are cleaned thoroughly with a wire brush or abrasive pad before applying flux. The fitting is compatible with standard 15mm and 8mm copper piping. To care for these installations, inspect the joints periodically for signs of oxidation or moisture. When heating, use a propane or MAPP gas torch, applying heat uniformly around the fitting until the solder ring becomes visible at the edge of the joint, indicating a complete seal. Avoid excessive heat, which can damage the temper of the copper.
