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 non-operational status of the pipe system and the fact that the new pipe is dommed for the same failures as the old pipe.

Nu Flow’s in-place 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 process utilize pull-in-place technology and blow-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.

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 for?
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 et forth in ASTM standards for CIPP rehabilitation.
