Major changes in the way building piping systems are engineered and constructed are resulting in their advanced deterioration. Also contributing to lower service life is the far lower quality and greater corrosion susceptibility of almost all pipe manufactured today.
Such issues easily explain the far longer service life provided by older piping systems and the accelerated failures documented at new properties barely 5 years old.
This area of our Internet site addresses some of the underlying issues to why no one should expect to ever see the service life for piping systems once guaranteed.
