Pipe Lining and Pipe Bursting Any plumbers a fan of either one? I feel like pipe lining is just a band aid, makes the drain smaller, and won’t actually fix a broken/offset/belly in a sewer without compromising the proper size of the drain.

Pipe bursting replaces the old sewer but what about having a proper pitch?

I don’t have any real life experience with either one so I’m just going off of logic (for a lack of a better term) but I’m more than willing to learn and be schooled on either process. 

Thanks in advance.
