More About Pipe Shield,
including Additional Benefits & Safety Information.
When building owners and property managers first consider pipe re-lining rather than pipe repair or replacement, they want to be sure they’re making the right decision. That’s our goal, as well.
To help achieve it, we’ve compiled a list of questions that we hear most often. We know you’ll find the answers to be informative; at the same time, we invite you to ask questions of your own that we will answer individually and perhaps even add to this page of our website.
Q. Why do we need Pipe Shield pipe re-lining?
Most domestic water piping systems are copper-based. Copper piping is susceptible to corrosion and wear caused by various environmental factors. The expected life span of copper piping is generally 15-25 years, although in recent years this number has dropped to as low as 10. There are many causes for failure, including pinholes from pipe pitting; however, leaks can also form from cracks that result from the combination of normal wear and pressure stresses on the pipe.
One factor for accelerated wear currently being investigated is called “aggressive water.” More and more districts are over-cleaning their water supplies to erase fears of E. Coli and other waterborne illnesses. The chemical mixture (aluminum, chlorides, chloramines, etc.) used to clean water supplies may be making the water “aggressive” and rendering copper piping vulnerable to chemical attack.
Q. How does the Pipe Shield epoxy coating work?
Pipe Shield is a proprietary epoxy lining technology designed to coat the inside of a pipe’s surface with a hard and impermeable barrier which is resistant to both chemical reaction and erosion. The epoxy bonds to its host pipe, and effectively becomes the water’s contact surface; this prevents existing pipes from corroding any further. The cured epoxy behaves like a ceramic, resisting chemical attack and corrosion. Its expected life span is approximately 50-75 years.
Q. Are there any benefits to Pipe Shield other than pipe protection?
As water passes through metal piping, many of the corrosive chemical cleansers used to process water supplies dissolve into and/or suspend in the water. This increases the concentration of metal particulates such as copper, lead, and steel in your drinking water. Studies have linked high metal concentrations in drinking water over long periods of time with various health risks. Since Pipe Shield becomes the active vessel in transporting your water supply, it protects you from metal infiltration into your water due to pipe corrosion and wear.
Q. Is Pipe Shield safe?
Pipe Shield is very safe. Cured epoxy is mostly inert (chemically non-reactive). The epoxy and abrasive coating we apply during the application are certified compliant and have been determined to be safe for public use. Both the epoxy in its final form as well as its constituent parts are tested for potential health effects. Pipe Shield is also tested for exposure over time by tracking the decay of various chemical concentrations up until 95 days following the initial application.
Q. Are there possible side effects related to the Pipe Shield product?
There are no side-effects attributable to the Pipe Shield epoxy coating.
Q. I’ve heard that epoxies carry a potentially unsafe chemical called BPA (Bisphenol-A) that can leach into water supplies. Does the Pipe Shield resin contain BPA?
That’s not true. Cured Pipe Shield resin is 100% non-toxic and poses no known health hazards.
