Pipe Restoration Technologies LLC (PRT), makers of the ePIPE, Lead-Free, Leak-Free and LeadSmart product lines, has received three Notices of Allowances from the U.S. Patent and Trademark Office. These allowances cover the ePIPE process in providing methods of placing a protective barrier coating for leak sealing protection and lead (Pb) reduction in underground drinking water pipes.
Pipes protected with ePIPE reduce the leaching of toxic lead and copper into drinking water to well below U.S. Environmental Protection Agency and World Health Organization cut-off levels. Pipes as small as a ½-inch in diameter can be protected in place using the patented ePIPE system and materials. The protection of lead service lines can be completed under four hours per line and often with no excavation on the home owner’s property.
The company now has over 20 issued patents in various countries. The ePIPE solution involves some 30,000 lead water supply pipes.
