Not sure I’d call PVC a total cure-all, though. I’ve seen a couple jobs where the roots found their way in at the joints, especially if the install wasn’t perfect or the ground shifted over time. Sometimes folks think once it’s plastic, it’s “set it and forget it,” but that’s not always how it plays out.
Also, swapping out the whole line is a big investment—sometimes a root treatment every year or two can buy you a lot of time if you’re not ready to rip everything up. I get wanting peace of mind, but for some people, that upfront cost just isn’t doable.
One thing I’d throw out there: if you’re dealing with monster trees, even copper sulfate or foaming root killers can help slow things down. Not a forever fix, but it’s kept a few basements dry in my experience.
Anyway, sounds like you made the right call for your situation. Just wouldn’t want folks thinking PVC means you never have to look at your drains again... roots are sneaky.
Yeah, PVC isn’t magic, that’s for sure. I had a section replaced a few years back and figured I was done worrying, but roots still found their way in at one of the joints where the ground settled weird. Ended up having to snake it anyway. Those root killers you mentioned do help stretch things out—definitely cheaper than digging up the yard every time. Sometimes you just gotta pick your battles and your budget, right?
PVC’s definitely not a cure-all, especially if the ground shifts or settles. I’ve seen roots sneak in even with supposedly “perfect” installs. Honestly, I’m not sold on root killers as a long-term fix—they buy time, sure, but if you’re getting repeat invasions at the same joint, might be worth looking at a flexible coupling or even re-bedding that section. Sometimes spending a bit more upfront saves you from the endless cycle of snaking and chemicals. Just my two cents...

Couldn’t agree more with that. I learned the hard way—tried to “win” with root killer and a plunger (don’t ask), but those roots just laughed at me. Ended up redoing a section with a flexible coupling, like you mentioned, and haven’t had to play plumber since. It’s wild how much peace of mind comes from just biting the bullet and fixing it right.
Totally get where you’re coming from. I tried the “cheap and easy” fixes for months—drain cleaner, augers, even boiling water (don’t recommend). Ended up paying more in the long run. Sometimes you just gotta get in there and do it right the first time.
