Founded by Bob Park, a graduate of the State Indentured Apprenticeship Program, Ameriserve Repiping Co. Inc. has been providing copper repiping and other plumbing services to Southern California residents since 1979 through its Van Nuys, California, headquarters. Though Ameriserve Repiping advertises on numerous popular radio shows, the firm is not a franchise of a national corporation, but rather a family-owned California business. Bob Park‘s daughters, Staci and Cammie, frequently answer the Ameriserve Repiping phone lines, while Bob Park and family friends Jeremy and John Waters typically conduct estimates at clients’ homes. An experienced craftsman, Bob Park worked on high-rise buildings, hospitals, and a space-shuttle launch facility before devoting himself fully to Ameriserve Repiping. The primary specialty of Ameriserve Repiping is copper repiping, which is designed to replace galvanized or iron household pipes with more stable, longer-lasting copper versions. Copper repiping is typically needed when the zinc that coats older pipes begins to break down, making the pipes rusty and causing leaks or poor water pressure. Before conducting copper repiping evaluations, Ameriserve Repiping professionals lay down a protective covering on the area to be evaluated, they then open small areas of walls where pipes protrude, such as behind toilets, under sink cabinets, and behind water heaters. Ameriserve Repiping professionals are trained to install copper piping without turning off the water; the only time water will need to be disconnected is for approximately four hours after installation in order to “convert” the new system. After the pipes are found to be in working order, the Ameriserve Repiping team will patch any openings they’ve made, leaving the patched areas in paintable condition. Ameriserve Repiping chooses to work with copper piping because of its reliability and long history of use in plumbing. Copper piping has been used by civilizations as far back as the Egyptians, and became a part of U.S. homes in the 1920s. Copper is also safe for use in drinking-water pipes, with the U.S. government recommending approximately 0.9 mg of copper for consumption per day for men and women.
