Aquatherm’s polypropylene-random piping systems and heat fusion connections are 100% lead-free. Its Green Pipe complies with national, third-party ANSI/NSF 61 (C.HOT 180° F/82° C) standards. The company also offers copper and stainless-steel fittings as an alternative to both standard and lead-free brass. Transition fittings (pictured) are available for potable water fixture sizes from 1/2” to 3” in diameter.
