i am currently doing a project, replacing a part of my internal soil stack ( which is being boxed in) Is there any difference between 110mm underground soil pipe (the brown one), and the grey/black/white 110mm soil pipe ?. and if not will all the connectors of the 110mm soil pipe whether grey etc, fit the 110mm brown underground pipe. cos i got a lot over and it would save me money if i can....

This is all about sunlight.

Has we all know plastics are corroded by sunlight.

The above ground plastic soil pipe has stuff to reduce the affects of sunlight damage.

The below ground soil pipe has stuff to reduce the affects of ground damage from acid soil, so I am told.

But if you ask me about what kind of life expectation of a ground soil pipe being use above ground, I couldn’t tell you.
