PVC plubming lifespan?

[tomfrh]

We have a 40 year old concrete pool with solvent welded PVC piping. Much of the piping is undergound.

The 40 year old piping still seems ok. How long does this stuff last? I want to know if it will need replacing any time soon.

This page suggests 100+ years, but it's an industry page, so not sure if it reflects real world

As a plumber (retired) I installed plenty of PVC in houses (indoors). It lasts virtually forever as long as it's not damaged, but it is somewhat fragile when abused (e.g., over heated, impacted, support undermined/eroded, physically stressed, intense UV exposure). I would say if it's lasted 40 years, I'd gamble it will last another 40 unless it's abused somehow.

My inlaws in Sacramento have a pool built in 1964 with all-PVC pipes. Still running just fine. Everything above ground has been replacd but not due to failure; everything below ground is original No leaks or other issues.
