W.C. Service Company provides water treatment services and has over 1,000 customers including major hotel chains, condominiums, apartment buildings, and office buildings. They have been in business since 1972 and use a food-grade phosphate compound approved for potable water systems to coat piping and decrease corrosion, pinhole leaks, and plumbing repairs. The treatment involves an initial site survey and inspection, followed by a customized treatment system and ongoing monitoring to protect plumbing and extend its lifespan at a lower overall cost compared to untreated systems over time.
