The Entire Deringer Product line Receives NSF Approval

Today, the entire Backflow Direct Deringer Product Line received certification per NSF/ANSI 372 Lead Free Requirements. The NSF/ANSI 372 certification is required in order sell backflow preventers in many US states [effective January 2014 per Safe Drinking Water Act (SDWA)]. This is a difficult, expensive, time consuming and tedious approval to obtain, however, it is a great feeling to have completed all 51 configurations of the Deringer product line in a single focused effort.
