216-677-2707PP-R & PP-RCT Polypropylene Piping
Fused polypropylene water piping that will not corrode, scale, or leak at the joints.
PP-R (polypropylene random copolymer) and PP-RCT (its higher-strength, heat-resistant version) are fused plastic piping systems used for domestic hot and cold water, recirculation loops, and hydronic heating and chilled-water lines. Unlike copper, polypropylene does not pit, corrode, or build up mineral scale, and unlike PEX or CPVC systems with mechanical or glued fittings, every joint is heat fused into a single piece of material.
On Our Way Plumbing installs PP-R and PP-RCT systems from manufacturers such as Aquatherm, selecting the correct SDR for the operating temperature and pressure. Smaller sizes are joined with socket fusion, larger mains with butt fusion, and branch connections can be made with fusion outlets or electrofusion fittings. Some products include a fiber-reinforced middle layer that reduces thermal expansion on hot water runs; we lay out expansion loops, offsets, and hanger spacing to the manufacturer's requirements so the system stays quiet and stress-free.
Polypropylene is a strong choice for commercial buildings, multifamily repipes, and residential projects where long service life matters. Call On Our Way Plumbing at 216-677-2707 for PP-R and PP-RCT piping in Cleveland and Greater Cleveland. Every system is pressure tested before close-in, priced upfront, and backed by our workmanship warranty.

PP-R & PP-RCT Polypropylene Piping FAQ
Common questions about our pp-r & pp-rct polypropylene piping service.
PP-RCT uses a modified crystalline structure that gives it higher pressure ratings at elevated temperatures. That often allows thinner walls and larger flow area for the same rating, making it popular for hot water and recirculation.
Yes. Polypropylene piping systems are manufactured and listed for potable water use. We install listed products and confirm acceptance with the local building department before starting.
PP-R does not corrode or scale like copper, and its fused joints have no crimp rings or glued fittings. It costs more upfront than PEX in many cases, but it is often chosen for commercial and multifamily systems for its durability and joint reliability.
