We had an issue with tree roots several years ago. No fun at allThe city pro-actively jetting out the sewer lines by my house yesterday, as they should be, per requirements. Trust me, that doesn't mean every city does.
A basement flooded a bit with sewage is a disaster, especially if you had gear and other valuables on the floor. Now I just have to make sure I get my service line TV'ed.
Many times when a house backs up it's roots or grease in your own service line, and not the city mains.
