How old are copper pipes in a home?
They are gray metal pipes and last about 40 years so they are due to be replaced where they are found in the 21st Century. The coating on old galvanized pipes flakes off, and the pipes will rust and become leaky as they age. Copper pipes began to be routinely used in the 1960s.
What causes copper pipe to leak / fail?
The pitting is deep and narrow, and results in pipe failure. Type II pitting occurs only in certain soft waters, with a pH below 7.2 and occurs rarely in temperatures below 140° F. The pitting that occurs is narrower than in Type I, but still results in pipe failure. Type III pitting occurs in cold soft waters having a pH above 8.0.
What to do with old copper water pipes?
Copper pipes more than 20 years old may have been joined with lead-based solders, so it is wise to have the water tested as a precaution. When left unprotected on construction sites, copper plumbing is a common target for thieves because the metal is valuable. Polybutylene plastic pipes were popular from the 1970s through the 1990s.
How long does a copper water line last?
Contrary to popular belief copper water piping doesn’t last forever. In its original design criteria, copper piping was projected to last for 20-25 years, but failure can often occur in as little as two years due to water chemistry.
