The LEaC Shield Advantage

  • Avoid having to replace bursting plastic pipe, metal connectors & manifolds.
  • Avoid replacing pinhole leaking copper, brass, and galvanized steel pipes.
  • Save on costly ongoing building repairs—as new pinhole leaks wreak havoc on walls, floors and wiring.
  • Remove the lead contamination of drinking water from corrosion of lead, copper, brass, and galvanized steel pipes.
  • Quick, “same day” installation costs less than 1% of total building pipe replacement.
  • Quickly stop existing water leaks and prevent the future leaks that “band aid” solutions—like re-plumbing, epoxy pipe-lining and rebalancing—can’t.
  • Total lifetime cost is 25% of epoxy coating or pipe replacement.
