Justin leads technical content at Hitze, where he translates 50 years of German-engineered piping know-how into guidance trade buyers can actually use. He works across the full system — multilayer PEX-AL-PEX, PEX-a/b/c, PE-RT underfloor pipe, PP-R and PPR-CU, plus press, compression, push-fit and lead-free brass fittings and manifolds — from resin grades, crosslinking and heat-fusion methods through to hydrostatic and oxygen-barrier performance. His focus is the part that trips up importers and private-label brands most: the certification maze (cUPC, NSF/ANSI 61, DVGW, WRAS, SKZ, CE with Declaration of Performance) that decides which product clears which market, and how to verify a factory before a container order. He writes for wholesalers, importers, contractors and private-label brands sourcing plumbing and heating pipe for North America and Europe.
