FAQs
What standard are these fittings manufactured to?
These fittings are manufactured to the EN 1254 standard.
Can these fittings be used for drinking water?
Yes, they are WRAS approved for use with potable (drinking) water systems.
What type of connection does this fitting use?
This is an endfeed fitting, designed for solder joint connections.
What is the primary purpose of a long radius bend?
A long radius bend provides a smoother, more gradual change in direction, which helps to minimize flow restriction and pressure drop in pipework.
Are these suitable for gas installations?
Yes, they can be used for gas installations, provided all relevant regulations and best practices for gas pipework are followed, including correct jointing.
How should I clean the fittings before soldering?
Use emery cloth or a pipe cleaning brush to ensure the ends of the copper pipe and the inside of the fitting are clean, bright, and free from oxidation or dirt.
What is the benefit of a 90-degree bend?
A 90-degree bend is essential for changing the direction of pipework by a full right angle, allowing for changes in direction in confined spaces or to navigate around obstacles.
Troubleshooting
Leaking joint after soldering
The joint was likely not heated sufficiently, flux was insufficient, or the pipe/fitting was not clean. Reheat the joint, ensure adequate flux, and re-solder. If the leak persists, the fitting may need to be replaced.
Solder not flowing into the joint
This usually indicates insufficient heat. Ensure the fitting and pipe are heated evenly and adequately before applying solder. Check that flux has been applied correctly.
Fitting discoloration before installation
Fittings may naturally oxidize over time if exposed to air and moisture. This is cosmetic and does not affect performance. Ensure fittings are thoroughly cleaned with emery cloth before fluxing and soldering.
Pros and Cons
Pros
- Manufactured to stringent EN 1254 standards.
- WRAS approval ensures suitability for drinking water.
- Durable copper material for long-term reliability.
- Provides smooth flow with a long radius bend.
- Cost-effective choice for trade professionals.
Cons
- Requires soldering skills for installation.
- Not suitable for high-pressure steam systems.
- Pack size may be excessive for very small jobs.
- Potential for leaks if soldering is not performed correctly.
Setup, Compatibility & Care
Setup:
- Ensure the ends of the copper pipes to be joined are clean, smooth, and free from oxidation. Use emery cloth or pipe cleaning brushes.
- Apply a thin, even layer of appropriate flux to the cleaned ends of both the pipe and the inside of the fitting.
- Insert the pipe fully into the fitting.
- Heat the fitting evenly using a propane torch.
- Apply solder to the joint. The solder should be drawn into the gap between the pipe and fitting by capillary action.
- Allow the joint to cool naturally without disturbing it.
Compatibility:
- Compatible with standard 15mm copper pipes for water and gas installations.
- Suitable for use with appropriate lead-free solders and fluxes.
Care:
- While copper fittings are generally maintenance-free once installed, ensure that joints are inspected periodically as part of routine system checks.
- Keep fittings clean and dry before installation to prevent oxidation.
