Pipe Restoration General Work Sequence – The Inside View

Step 1: Pipe system diagnosis and set-up

Expose existing access points or create access points. The existing pipe system is inspected for integrity and breaks in pipe using a drain camera. Corrosion, roots and missing sections in the pipe are located. Temporary bypass drain piping provisions are installed as necessary.

Step 2: Pipe Cleaning

Debris, roots and corrosion are removed from the pipes using a Nu Flow pneumatic cutting tool. A wide variety of different cutting heads can be selected for use depending upon the type of pipe system and the severity of the buildup inside. The pipe is restored back to its original diameter.

Step 3: Pipe Lining

An epoxy-saturated felt liner with an internal bladder is pulled through the cleaned pipe system, using the existing access points. The bladder is inflated, which pushes the epoxy liner along the internal circumference of the pipe. This liner can bend through elbows, Ts and Wyes.

Step 4: Cure and System Evaluation

The epoxy cures within hours. The bladder is removed, leaving a strong, seamless, structural pipe within the host pipe. This protective liner will prevent future failures. A final leak test and inspection is performed.

Frequently Asked Questions:

How can I tell if there’s a problem with my plumbing?

Common indicators of failing drain lines are cracks in the visible pipes, leaks, water stains, mold, slow drains and backups.

What types of pipe systems can you line?

We have the technology to line the following mechanical pipe systems: vertical sanitary stacks, horizontal sewer lines, mains, roof drain systems, processed piping, conduit lines, fuel lines and chemical lines with diameters 2″ to 12″ and bigger in some specialty applications.

How long have you been doing this?

Nu Flow’s structural liner and unique pull-in-place process was developed in the 1990s and has been used on thousands of skyscrapers, commercial buildings, multi-unit residential complexes, houses, federal structures, churches, schools and other buildings.

Why should I line my pipes instead of repiping them?

A repipe is a traditional means of repair where a plumber will remove the failing pipe and replace it with a new pipe. This repair method has many disadvantages, which include the creation of a messy construction site, high time consumption, the destruction of finished floors, walls, ceilings and other structures, the nonoperational status of the pipe system and the fact that the new pipe is doomed for the same failures as the old pipe.


Nu Flow’s in-place pipe lining solutions are non-destructive, eco-friendly, non-invasive, cost-effective and can be installed in a fraction of the time. Nu Flow’s patented processes utilize pull-in-place technology and blown-in technology that only require pipe access points (clean outs that should already exist for maintenance). The epoxy liner is pulled into place and then left to cure, so there is no damage or disruption to the building, tenants or residents.

What is the lifespan of your liner?

Test results show that our Nu Drain epoxy’s life expectancy to be more than 50 years.

How much access is needed to rehabilitate a pipe line?

The access points, cleanouts and manholes we utilize are already present.

How many hours does the epoxy take to cure?

It takes less than a day for the different epoxies to cure, depending on length and temperature of the pipe.

How long does the water need to be off?

With some drain applications, the pipe systems don’t even need to be turned off. If necessary, the pipe system can be worked on and nonfunctional during the least inconvenient hours for the building.

Is your pipe lining safe?

Our epoxy meets or exceeds the physical properties set forth in ASTM standards for CIPP rehabilitation.
