The Challenge

The facility had experienced electrolysis problems in its domestic water supply system and needed to replace the lines with minimal disruption to patients and staff.


The Solution

Aquatherm provided considerable savings – at least $25,000 worth – while eliminating electrolysis worries and delivering an unrivaled warranty.


A relatively new to North America piping system won over 20-and 30-year plumbing industry vets to help alleviate a Tennessee VA hospital's water distribution woes.

Since 1903, James H. Quillen VA Medical Center has been improving the health of the men and women who have proudly served our nation. Completed in 1989, the four-story, 280,000-square-foot building in Mountain Home, TN, has served tens of thousands of recovering veterans, with 200 residing in its domiciliary.

However, in fall 2009, the facility maintenance staff discovered that the building's main six-inch galvanized steel water line, which ties into copper when it reduces to a four-inch line, was deteriorating. According to Aaron M. Prosak, the facility's Engineering Technician, "This union of two dissimilar metals was creating electrolysis in the galvanized pipe."

He explained that the pipe was extremely brittle and required "near surgical care to finish the work on it." Kevin Hoover, with the Knoxville office of Ferguson Enterprises, recalled that the grooved steel "was leaking, pitting and deteriorating, and was soon going to rupture."
