How do you remove calcium buildup in tank water pipes which is clogging up?
Traditional methods of removing calcium buildup in residential/commercial/industrial water pipes and hardware often involves using harsh chemicals to break down existing buildup (and ideally, prevent future or continued buildup). If calcium buildup is allowed to persist and/or worsen, it will often result in a loss in water pressure, water quality, and can compromise the the integrity of not only the pipes, but any and all hardware (such as pumps, filters, and heaters) that is attached to the given water system. Often, to avoid costly repairs to the more expensive components of a particular plumbing system, sections of pipes compromised by calcium buildup (if they can be identified) are simply replaced periodically in lieu of the aforementioned harsh chemicals or expensive filtration systems needed to breakdown and/or prevent such deposits.
A relatively new and "green" alternative to these more traditional methods are electronic water conditioners. Companies such as Hydro Path (http://www.hydropath.com) and Hydro Care (http://www.hydrocareus.com) provide affordable solutions for the elimination of all manner of scale buildup in water systems. From smaller units intended for residences, to a variety of industrial level models, these technologies attach to the outside of main input pipe for a given water system, and induce a constant electric charge to the water flowing through the pipe. The charge ionizes compounds (such as calcium), which form bonds with other molecules in the water rather than with the walls of the pipe. Not only does this technology act as a preventative measure against scale buildup, it works retroactively and efficiently to break down existing scale.
