ePIPE® Team Awarded U.S. Patent – bringing lead service line (LSLs) into compliance with US EPA guidelines for leaching of toxic lead (Pb)

LAS VEGAS, NEVADA – September 19, 2017

Pipe Restoration Technologies, LLC, (PRT) makers of the ePIPE®, Lead-Free, Leak-Free™ and LeadSmart® product lines, announced that it has been granted U.S. patent #9764354. This patent is related to the ePIPE system of in-place pipe restoration which reduces lead (Pb) leaching from underground water service pipes to well below the current US EPA cut off level for lead.

“ePIPE continues to provide solutions to real-time issues by providing protection against the leaching of toxic lead, from lead service lines (LSLs). Pipe Restoration Technologies CEO Larry Gillanders said. “With an estimated 6 million lead service lines still in in use in the US, ePIPE applicators save their customers time and money with the patented ePIPE process.”

“Protecting underground LSLs can be completed in under four hours per line, at a considerable cost savings when compared to replacement and often with no excavation on the home owner’s property.”

Pipes protected with ePIPE reduce the leaching of toxic lead into drinking water to well below U.S. Environmental Protection Agency (EPA) and World Health Organization (WHO) cut-off levels. Pipes from as small as 1/2” in diameter can be protected in-place.
