Plumbing solder is the filler metal that bonds copper pipe to fittings when heated, forming the watertight sweat joints used throughout copper supply systems. Moonshine Bath stocks lead-free plumbing solder suitable for potable water, alongside the fittings and tools to complete the job.

Frequently Asked Questions
Do I have to use lead-free solder for water lines?
Yes. Code requires lead-free solder on potable, drinking-water systems. Lead-based solder is only permitted for non-potable applications. Always pair it with a compatible flux.
Do I need flux as well as solder?
Yes. Flux cleans the metal and helps the molten solder flow into the joint by capillary action. Apply flux to clean pipe and fitting before heating and soldering.
