@Clay O.Thanks Clay.

I've heard that something to be careful about in Jackson, MS is Yazoo clay. 

Hey @Clay Savage, love the title of this post haha!

So the main sewer lines were made of cast iron and in some cases clay material, which can allow roots to intersect the pipe and cause major problems. 

You never know with clay, you could have one house with a problem and the one next door does not have a problem.

Our soil is predominantly clay so it goes through a lot of expand/contract cycles when it rains.

Hi @Michael Clay,There are definitely different schools of thought on your approach, but even if you think it might have been a mistake, sometimes we can get away with mistakes :)  If you left a bottle of liquor for a recovering alcoholic, this could have gone south pretty quickly, but it worked out and to your benefit. 

Depending on age, it could be clay, which is particularly susceptible to breaking / blockage.

Most are slab and due to our soil, we can get settling from clay expansion/contraction and also we get sinkholes in this area so when there are structural issues, it’s a must to get an engineering report to determine if they are caused by the clay or sinkhole activity.
