Neofit®+Plus: Expandable Pressure Pipe for Potable Service Lines
Neofit®+Plus is a structural Expandable Pressure Pipe (EPP). EPP does not require the host pipe to maintain its pressure tested strength.
The NSF 61 approved Neofit®+Plus Expandable Pressure Pipe (EPP®) is a non-invasive, advanced pipe technology designed to re-pipe and restore leaking underground water services with inside diameters from 1⁄2" to 2". The Neofit EPP® forms a continuous barrier between the existing pipe and drinking water, making it ideal for Lead Replacement Programs. It can be installed inside steel, copper, plastic, and lead pipes in lengths up to 300 ft. The smooth-bore, thin-wall pipe provides the same or increased flow capacity. Neofit+Plus often requires only a single small access pit, saving yards, sidewalks, floors, and more from costly demolition. The speedy Neofit+Plus process allows for multiple installations per day and an immediate return to service, with installation times typically ranging from just two to three hours. This innovative re-piping solution has been installed in thousands of water service lines throughout the world. Save up to 85% by ditching the traditional dig-and-replace method and upgrading to Neofit+Plus.
Water Authorities and Ratepayers need every possible certified tool in their toolbox to address the lead crisis in the United States, and Neofit+Plus EPP is that tool. Engineered to last and resistant to leaching, its structural material has been scientifically evaluated* for a service life exceeding 100 years. Neofit+Plus EPP enables water authorities to re-pipe lead and aging service lines while balancing affordability, project timing, phasing, and infrastructure planning. We tested Neofit+Plus after installation inside a lead service pipe by following AWWA’s field guide for hydrostatic testing of water service lines* and then analyzing the water for lead. The results showed 0% lead detected in the water, demonstrating the effectiveness of the continuous barrier created by the Neofit+Plus system.

what’s next? — Neofit+Plus Main Connection System
An upcoming addition to the Neofit system: Neofit+Plus Main Connection System allows the NSF 61 certified Neofit+Plus EPP to be installed in ½” to 1” ID water service lines from inside water mains 8” to 12” ID. This eliminates the need to dig up the water main in the street at each service connection. Only one access is required at each end of the water main pipe to allow the installation of Neofit at each connecting service pipe. Additionally, if trenchless lining methods, such as CIPP, are employed in the water main, the Main Connection System can be utilized to line the service pipes at each tap from inside the lined water main pipe.

A Flow-Liner® Certified Neofit+Plus Installer Success Story
A homeowner in Pittsburgh was dealing with a leaking 1-inch copper water service line stretching roughly 200 feet from the home to the municipal shutoff. The line ran down a steep wooded hillside, making excavation extremely difficult and potentially hazardous. In addition, part of the line passed beneath a newly installed heated concrete driveway, which the homeowner was determined not to disturb.Traditional dig-and-replace methods would have required major excavation, significant landscape disruption, and driveway demolition—costly, invasive, and time-consuming. Their plumber turned to a Flow-Liner® Certified Neofit+Plus Installer for a trenchless solution.
The Flow-Liner Certified Installer utilized the Neofit+Plus Expandable Pressure Pipe (EPP), a proven, minimally invasive method designed specifically for water service line rehabilitation.Using Neofit+Plus, the team successfully rehabilitated the full 200 feet of existing 1-inch copper service line, navigating approximately 25 feet of elevation change from the home to the street shutoff.Only one excavation pit was needed at the curb stop. Access at the interior shutoff provided the second access point—no trenching, no hillside excavation, and no disturbance to the driveway.
The Neofit+Plus rehabilitated water service was tested and returned to full operation the same day. The homeowner avoided major property damage, excavation costs, and lengthy downtime. The completed Neofit+Plus now provides a new, durable, seamless, NSF-61-approved internal pipe, designed for long-term performance. The homeowner was extremely pleased with the results—and with the fact that their newly installed heated driveway remained untouched.
