Epoxy Pipe Coating Process | Nu Flow


Nu Flow’s epoxy pipe lining process restores corroded or eroded piping systems without the costly expense and disruption of pipe replacement. Unlike a conventional re-pipe, our process requires no demolition to your home or business. By creating an epoxy barrier between the water and copper piping you eliminate the chance of pin-hole leaks, slab leaks, low water pressure, pipe corrosion and contaminants leaching into your water supply. Nu Flow’s patented pipe restoration technology is a proven and permanent solution.

Why re-pipe? …when you can renew with Nu Flow!

How It Works


Setup and Plumbing System Diagnosis

Proper floor protection is used to protect all flooring surfaces throughout your home. The project begins with a pressure test to determine if your home has any existing leaks. Once pressure test has cleared a “flow” test is performed at all fixtures to determine flow rate and water pressure. Next, the Plumbing system is mapped out using a Pulsar 2000 tracing system. A plan is implemented to minimize disruption and afford the most efficient time line for work completion. The piping system is inspected for integrity and spot repairs are made to excessively worn joints and fittings.

Pipe Cleaning and Prep

The entire plumbing system is then drained and dried using dehumidified compressed air. A safe abrading agent is then blown through the pipe system, removing rust, scales and corrosion that have built up over time, while at the same time lightly etching the pipe to prepare for the epoxy coating process. Air is applied once again to remove any remaining garnet.

Epoxy Coating

Optimal internal pipe surface temperature is created prior to epoxy coating. Another air pressure leak test is performed. Conditioned air is then introduced into the pipe to evenly distribute the epoxy coating throughout the piping system. Following the coating application, conditioned and controlled air flows through the pipes to facilitate epoxy curing.

System Reassembly and Final Inspection

The end result is a smooth, permanent epoxy coating barrier between your pipes and water. After the epoxy coating cures new valves and hoses are installed to all fixtures. A final pressure test and flow test is performed to confirm system functionality.

The Benefits

Safe and Durable:

Nu Flow’s epoxy is UL certified safe to NSF/ANSI Standard 61. Nu Flow’s epoxy was developed and patented by the U.S. Navy and has been successfully applicated by Nu Flow technicians since the mid-1980s for the U.S. government and in domestic, commercial, industrial, and other applications. Testing engineers estimate the life expectancy of the epoxy is roughly 100 years.

Cost Effective:

Epoxy Coating is as much as 50% less expensive than traditional pipe replacement costs. Coating is a non-invasive process, so there is no destruction to buildings, hardscape or landscape. Reconstruction costs for repiping are as much as 60 percent of direct pipe repair costs and epoxy coating eliminates the need for reconstruction.

Minimal Downtime / Disruption:

The epoxy coating process takes a fraction of the time of traditional re-pipe methods. For example, a re-piping job that would normally take a full 4 to 6 weeks can take as little as 4 days for Nu Flow to complete. Nu Flow’s pipe restoration process is quick, quiet, non-invasive, and requires no displacement of a building’s occupants.


Our epoxy coating process was developed and patented by the U.S. Navy and has been successfully installed by Nu Flow technicians nationwide for nearly 30 years. With the largest base of installers and the highest success rate in the industry, Nu Flow has the knowledge and experience to handle any type of job. With projects ranging from Naval Ships and Aircraft carriers to residential homes and commerical buildings, no job is too big or too small!
