I laid down hundreds of feet of SOLID ABS sewer system back in the mid-1980’s, and I never heard of the solid ABS pipe breaking down except from prolonged exposure to direct sunlight. You’ll find that cellular core ABS pipe exposed to UV from the Sun does eventually deteriorate, but only if it is left unpainted.
The black color of ABS pipe comes from the carbon black UV inhibitor that is part of the material, so it is very resistant to UV even if left exposed, and unpainted.
AFAIK, Building Codes typically prefer (if not outright require) SOLID ABS sewer line to cellular core ABS, and they usually require that any roof penetrations have a thorough coating of paint.
If your problem child wasn’t exposed to UV, the deterioration was likely due to another cause; maybe material incompatibility as might be encountered trying to glue ABS pipe using PVC solvent, or the other way ‘round.
Glad you’ve got it beat, though.
It was a joint failure, basically the temperature extremes here caused stress fractures from continual expansion and contraction.
This is not a sewer line, it is a septic-system fume vent that was leaking into the house. And yes, thank you, it is all sorted out now.
And also thank you for the information about ABS, UV inhibitor, and the durability of same. I'll stop planning to have all the ABS replaced. ;-)
I second TOL’s thank you.
