Nu Flow's Small Diameter Re-Line allows plumbers to re-line complete lateral systems.  By using Nu Flow's cutter, plumbers can reinstate lined laterals.  Branch lines can then be lined to the stack quickly and easily.  By using Nu Flow's small diameter pipe lining, it gives you the benefit of being able to line complete systems right from the 3" (65mm) or 4" (80mm) stack down to the 1.5" (40mm) branch lines.
