I live in a 100+ year old house and in this part of the world that basically means that your sewer pipes will be dodgy old brittle earthenwear made in the early days of settlement, when people sort of made do with whatever they could. The soil here is highly reactive and the summers are dry as hell and the winters are wet... we ended up replacing a lot of cracked pipe full of tree roots.
If it is legal where you live, send doses of copper sulfate down those pipes regularly during the nearest trees' growing seasons to kill hair roots before they turn into major tree roots. You can't do much about major roots without risking chewing up what pipe is still intact, but you can kill hair roots before they become major roots. And that's about all you can do other than replace the pipes.
*shudders* I doubt very much if it's legal, but I'll look. Thing is that with these pipes, it's possible that any chemical is going to erode the binder even faster. Bleh.
They are going to get replaced at some point. I'd just rather not be here when they need to be.
