Plumbing & Mechanical recently interviewed Tomas Lenman, owner and founder of MrPEX Systems, near the company’s headquarters in Ramsey, Minn. He retired a year ago when Jan Andersson became company president.
Lenman began his career in 1971 as an engineer with Wirsbo Bruks in Sweden, where he developed the first PEX production process. He went on to develop standard specifications for PEX tubing in Europe and Australia.
