Product Information
Full details
The Primaflow Lead Free Solder Wire is designed for professional plumbers and serious DIY enthusiasts who require a reliable, safety-compliant solution for copper pipe joints and plumbing installations. This high-quality wire ensures strong, leak-proof connections across a variety of residential and commercial plumbing systems, though users should note that lead-free solder typically requires a slightly higher melting point and more precise heat management than traditional leaded variants.

FAQs
Is this solder safe for drinking water?
Yes, this lead-free solder is specifically designed to meet safety requirements for potable water plumbing.
Does this require special flux?
It should be used with standard plumbing flux designed for lead-free soldering to ensure proper flow and bonding.
Can I use this for electronics?
This wire is optimized for plumbing; it is not recommended for electronics as the flux type and alloy composition differ from electronic-grade solder.
How much solder is in the package?
The package contains a 1/2kg spool.
Why is it harder to melt than older solder?
Lead-free solder has a higher melting point than traditional leaded alloys, requiring a slightly hotter torch or longer heating time.
Troubleshooting
Solder is not flowing into the joint
Ensure the pipe is sufficiently heated and that enough flux has been applied to the joint surfaces.
Solder bead is forming but not bonding
The surface is likely dirty or oxidized; clean the copper with an abrasive pad and re-apply flux.
Joint leaks after cooling
Check for gaps in the pipe fitment or insufficient heat penetration during the soldering process.
Pros and Cons
Pros
- Safe for use in drinking water systems
- High-quality bond strength for copper plumbing
- Generous 1/2kg capacity for multiple repairs
- Professional-grade consistency and flow
Cons
- Requires higher heat threshold than leaded solder
- Demands precise cleaning of surfaces for best results
- Limited to specific soldering applications
Setup, Compatibility & Care
To achieve the best results, pair this wire with standard copper piping and compatible lead-free plumbing flux. Always ensure your workspace is well-ventilated, even with lead-free alternatives, as flux fumes can still be an irritant. For care, store the 1/2kg spool in a cool, dry place away from direct chemicals to prevent oxidation of the wire surface, which can interfere with flow during the heating process. When finishing a job, ensure the solder is completely cool before pressurizing the plumbing system to verify a perfect, leak-free seal.
