The historic acidic water supply of Greater Vancouver produces a corrosive effect on copper piping and slowly dissolves the pipe wall causing the pipe wall to wear thin. Electrolysis, high velocity water flow and undersized piping are other reasons for pipe failure. The result is a plumbing system plagued with pinholes, leaks and in need of frequent costly repairs. The “band-aid” method of a rubber hose and clamp covering pinholes on the pipe is a quick-fix temporary solution. However, this method is most often short-lived. In our experience, total water pipe replacements have been necessary to buildings as young as eight years in age.
