Yes, Primaflow endfeed copper fittings are designed to be suitable for gas systems when installed to the correct standards.
No, these are copper endfeed fittings specifically designed for copper pipework. You would need a compression fitting or a specific push-fit adapter to connect to plastic.
Yes, for any system involving drinking water, it is a requirement to use lead-free solder to ensure safety and compliance with WRAS regulations.
Ensure the pipe is polished until shiny, apply flux evenly, and heat the fitting until the solder melts instantly upon contact.
No, endfeed fittings are designed for permanent installation. Once soldered, they generally cannot be reused.
WRAS (Water Regulations Advisory Scheme) approval confirms the product is safe for contact with drinking water and will not contaminate the supply.
The joint was likely not heated enough for the solder to flow, or the pipe was not cleaned properly; clean the area, reheat, and re-apply solder.
Check that the pipe is sufficiently heated and that sufficient flux is applied; ensure the gap between pipe and fitting is not obstructed.
This is often due to residual flux; ensure you wipe down the completed joint thoroughly with a damp cloth.
To install, ensure the 22mm copper pipe ends are clean and free of burrs by using a pipe cutter and wire wool. Apply flux sparingly to the cleaned pipe end, insert it into the coupling, and heat the joint evenly with a blowtorch. Once the pipe is hot enough to melt solder on contact, apply lead-free solder to the mouth of the fitting, allowing capillary action to draw the solder into the gap. Allow the joint to cool naturally without moving it. For care, wipe away excess flux with a damp cloth immediately after soldering to prevent long-term surface corrosion.
