PVC is definitely a solid choice, but it's not totally bulletproof. I've seen roots eventually find their way into PVC joints if they're not sealed properly or if the pipe shifts over time. It's rare, but it happens. One thing I've found helpful is adding cleanouts strategically along the line—makes inspections and maintenance way easier down the road.
Also, good call on tree selection. Oaks can be stubborn, but maples and willows are even worse in my experience. Had a customer once who insisted on planting a willow right next to his sewer line because "it looked nice." Sure enough, two years later we were back digging up his yard again...lesson learned the hard way.
Anyway, sounds like you're set for now. Just keep an eye out for any slow drains or backups—catching root intrusion early saves a ton of hassle later on.
PVC is pretty reliable, agreed, but I've seen roots sneak into even properly sealed joints after a decade or so—nature finds a way eventually. One extra step I've found helpful is installing root barriers around the pipe trench itself. Basically, you dig a narrow trench parallel to your sewer line and insert a vertical barrier sheet. It's not foolproof either, but it definitely slows down aggressive roots like maples or willows...worth considering if you're planting new trees nearby.
Good point about root barriers—I've seen them help, especially with younger trees. Still, I've had cases where mature tree roots went surprisingly deep beneath the barrier. Ever tried combining barriers with strategic tree species selection to minimize root intrusion long-term?
"Ever tried combining barriers with strategic tree species selection to minimize root intrusion long-term?"
Yeah, that's exactly the way to go. Root barriers alone are decent, but they're not foolproof—I've seen roots from mature oaks and maples laugh at them and dive right under. Honestly, pairing barriers with smarter tree choices is the real long-term fix. I swapped out a couple aggressive maples for smaller ornamentals a few years back, and haven't had to dig up my driveway since... knock on wood.
Yeah, barriers can help, but honestly I've seen roots do some pretty wild gymnastics to get around them. Last summer, we dug up a sewer line that had been completely invaded by roots from a supposedly "safe" ornamental cherry tree. I mean, who knew those little guys could be so determined? So yeah, smarter tree choices definitely help, but I'd still keep an eye out—roots seem to have minds of their own sometimes...
