PVC Pipe, Underground and Out of Mind
| Pipe Material | Expected Life Span Underground |
| Copper | 70 – 80 years |
| Galvanized Steel | 50 – 60 years |
| Cast Iron | 70 – 80 years |
| PVC | 100+ years |
What is the average life expectancy of copper pipe?
The life expectancy for these supply pipes are typically 40 to 70 years for brass, 20 to 50 years for galvanized steel, and at least 50 years for copper. For pipes that are used as drain lines, their life expectancy is somewhat longer because they are not under a constant amount of pressure.
When should you replace copper pipes?
Levels of Pipe Replacement
- Spot fix. When you find leaking copper pipes, you can take the bare minimum approach, cutting out the bad section and replacing it with PEX. ...

Does copper pipe corrode underground?
Summary. Copper water tubing has an outstanding history of corrosion resistance in most underground environments. Copper does not naturally corrode in most clays, chalks, loams, sands, and gravels. Certain aggressive soil conditions, however, can cause it to corrode.
Can copper pipe last 100 years?
Regardless of the material, each of these plumbing products have a life span that you should know so you can gauge whether you need an upgrade. Brass, cast iron, and galvanized steel have a life span of 80 to 100 years, copper lasts 70 to 80 years, and PVC piping only survives for 24 to 45 years.
What happens to copper pipe underground?
Copper is naturally corrosion resistant to most soils and underground environments. Wrapping or sleeving the copper tube in an effort to provide an additional layer of protection, while well intended, can lead to failure due to improper sleeving or wrapping practices.

How do you protect a buried pipe in the ground?
Buried pipelines are best protected by judiciously combining coatings with cathodic protection. As far as practical, pipelines should be buried in dry crushed rock with sand.
How do you stop copper pipes from corroding?
Install a phosphate feeder before the copper piping. Phosphate will coat the piping and reduce or slow down the corrosion effects by coating the piping's interior surfaces with phosphate and causing an insulation surface to be built up.
Do copper pipes get pinhole leaks?
As copper ages, the inner lining of the pipe weakens, making them more prone to pinhole leaks. The most cost-effective option may be to re-plumb your home.
Should I replace my copper pipes with PVC?
Resistant to corrosion, abrasions, and impact damages better than copper pipe because plastic doesn't corrode. PVC pipe is thicker than copper which also helps with impact damages and abrasions. Less noise compared to copper piping, even with higher water velocities and speeds.
Does copper plumbing go bad?
Copper pipes can last for around 50 years, but they eventually do go bad. Copper is corrosion-resistant, not corrosion-proof, and a specific type of corrosion from exposure to formaldehyde can cause copper to weaken early. Leaks from copper pipes are often slow, making them harder to notice.
