Helpful Hints for Soldering New Lead Free Brass
Following enactment of amendments to the Reduction of Lead in Drinking Water Act in effect since Jan. 1, 2014, new brass alloys have been introduced that comply with the new definition of Lead Free. Some contractors have been reporting difficulty soldering these new alloys, finding poor coverage when joints are broken apart. The industry has been advising installers to practice with the new materials to gain confidence in specific techniques; helpful tips are available here.
Having Trouble Soldering No-Lead Brass?
Practice your technique using these helpful hints:
- Joints need to be carefully cleaned and free of oils.
- Work with vendors to find the flux material that works best in the application; some fluxes have better performance with the new brass alloys.
- Apply the heat slowly and evenly around the pipe and then the fitting, being sure to apply the heat by moving the torch around the fitting, not simply heating in one location.
- Allow additional time for the joint to cool before moving; the new alloys take longer to heat and will take longer to cool, factors that can affect success.
Are you and your techs having problems soldering the new no lead copper alloys or finding poor coverage when joints are broken? There are quite a few misconceptions and myths related to why installers are having difficulty soldering the new lead free products. This webinar will clear up any myths you’ve heard. Learn the proper installation practices to get consistent high quality soldered joints for lead free pipes, valves and fixtures.
