Sometimes you get lucky, sometimes you end up chasing leaks after the fact.
That’s the part that always makes me nervous with older terracotta. I’ve had a couple rentals where hydro jetting did more harm than good—one time it actually cracked a section and I had to dig up half the yard. Not fun.
Here’s what’s worked for me over the years:
- Mechanical auger first, like you mentioned. It’s not perfect, but it’s gentle enough for old pipes.
- If I have to use hydro jetting, I’ll ask the plumber to keep it under 1500 psi and do short bursts. Anything higher and those old joints just can’t take it.
- After clearing, I usually schedule another camera check a few months later. Sometimes roots sneak back in faster than you’d think.
- Root barriers are great if you can find the entry point, but honestly, sometimes it’s just not practical with big trees or tight spaces.
I’m with you on chemicals—tried copper sulfate once and regretted it when my neighbor’s tomatoes started looking sickly. Never again. It really is about finding that balance between fixing the problem and not making a bigger mess down the line.
I get the hesitation with chemicals, but I’ve actually had decent luck with foaming root killers—just the kind you flush down the toilet. They seem less harsh than copper sulfate and haven’t messed with my neighbor’s garden (yet). Not a silver bullet, but sometimes it buys me a year or two before roots come back. Hydro jetting still makes me nervous on those old lines, though... one bad crack and you’re in for a world of hurt.
I get the appeal of those foaming root killers, but I’m still a bit wary of putting any chemicals down the drain, even the “safer” ones. Had a plumber tell me once that sometimes those products can gum up older clay pipes over time. Ever tried any of the enzyme-based stuff? I’ve heard mixed reviews, but if it actually works without the chemical load, I’d be willing to give it a shot. Curious if anyone’s seen a real difference with those.
I hear you on being cautious with chemicals, especially in older clay pipes. Those foaming root killers can be a double-edged sword—sometimes they do the trick, but I’ve seen them leave behind a weird residue that just collects more gunk over time. As for enzyme-based stuff, I’ve tried a few brands at clients’ places. Honestly, they’re better at breaking down organic sludge than actually dealing with roots. If you’re dealing with grease or general buildup, enzymes can help keep things flowing, but roots are stubborn. Once they’re in there, it’s usually a mechanical job—snaking or hydro-jetting—unless you want to keep pouring money (and products) down the drain.
Funny enough, I had one customer who swore by flushing rock salt every few months. Not exactly scientific, but he claimed it kept the roots at bay. Personally, I’d rather see what’s going on with a camera before dumping anything in there. Sometimes old-school methods work, sometimes you just end up with salty pipes and no real fix.
I get where you’re coming from on the chemicals, but I’ve actually had decent luck with foaming root killers in certain situations—mainly when the roots are fine and not totally clogging things up yet. The key is timing and not overdoing it. That said, I agree, nothing beats a camera inspection first. Hydro-jetting’s my go-to for major blockages, but I’ve seen folks do more harm than good with DIY snaking if they don’t know what they’re hitting down there. Rock salt though... I’m skeptical. Seems more like wishful thinking than a real fix.
