It can happen in old iron pipes and also old clay pipes.

Still had cast iron pipes in basement.

Scoping the sewer upon purchase is a good idea, especially if its cast iron.

The one-year agreement we currently have, which is shorter than the other PM’s I spoke to offered, seemed short enough in my eyes but we never ironed out a separation policy which is where I dropped the ball.

Have had multiple camera inspections of my pipes, and they show a crack in the cast iron pipe which caused the backup.

Isn't it ironic how the one time borrowers got a 'leg up' in the form ridiculously low interest rate mortgages that those same 'assets' are partially what is behind the collapse of several significant US banks and beyond? 

Iron Range, similar story.

It's even more disheartening when it comes from a local such as @Travis Biziorek who ironically manages properties in the City (I guess). 

Trying to iron out whole will give me the best rate. : ) 

Flowable fill does not equal mud pumping under pressure.Are the existing drain lines cast iron or PVC?
