Doesn’t adding an epoxy lining to pipes make them narrower? Wouldn’t that mean that there would be less water flowing through and at higher pressure?

Patrick, depending on the diameter of the pipe, the epoxy coating is applied to a thickness between 0.20 and 5 millimeters, resulting in a corresponding reduction in interior pipe diameters. Applied to these specifications, it has never caused velocity or delivery problems in systems. In fact, cured epoxy’s surface is so smooth that it creates less friction than new copper. So even with the reduced diameter caused by the coating, the flow rate is actually greater than an uncoated pipe. We have upgraded over 12,000 suites during the past 10 years, and to date we have not had a velocity or flow problem.

The existing copper pipes in your building may already have a coating of copper oxide (green scale), galvanized steel pipes may have extensive corrosion and buildup. While the corrosion build up in copper pipes may not be as thick as the epoxy lining we apply, the corrosion currently coating your pipes can be extremely rough, causing turbulence and reduced water flow.

By contrast, lined pipes are glassy smooth. This offers little restriction to water flow. Most importantly, unlike new pipes, they remain glassy smooth over the years and never restrict water flow.
