Pinhole Leaks & Repiping

Built in the late 1960s, this 200 unit residential project was experiencing pinhole leak after pinhole leak in its copper water supply system. Upon investigation, it was found that failure of the copper piping system was widespread, and corroded piping was affecting both hot and cold water lines. No single area of piping was immune to the effects of the pinholing. While questions as to the cause of such widespread failure remain, both managers and owners quickly came to the conclusion that a complete repiping of the entire building might be necessary.

Conventional repiping would include two major considerations -- long periods of time for residents to be without water, and massive destruction while all of the piping was replaced. All of this would make the total cost very high both monetarily and convenience wise. Determined to find a cost-effective solution, the Webster House board focused on finding a solution that would be cost effective, the least disruptive and lasting.

In discussions with officials of the metropolitan Washington Suburban Sanitation Commission (WSSC), it was brought to everyone's attention that a process of in-place pipe restoration developed by ACE DuraFlo Systems might just provide the answers to the board's dilemma.

ACE DuraFlo approached the solution to piping corrosion by applying their proprietary NSF approved epoxy lining material on the inside of piping. This in effect created a new epoxy lined pipe within the old pipe protecting the interior surface of the pipe from further deterioration. All of this was accomplished without pipe removal and without wall or system destruction.

ACE DuraFlo has completed pipe restoration projects on the west coast in schools, major resorts, hotels, single-family homes and multifamily projects. Both copper and galvanized piping systems have been restored using the ACE DuraFlo® system.
