Dealing with old cast iron is never as straightforward as those quick DIY videos make it seem. I’ve run into the same headaches—sometimes you think you’re just swapping a drain, and suddenly you’re knee-deep in rust flakes and mystery fittings from the 1950s. Renting tools is definitely the way to go for those one-off jobs, unless you want your garage to turn into a graveyard for pipe cutters and sawzalls.
On the recycling front, most of the time I just take the old metal to a local scrap yard. They’ll usually pay a bit for cast iron or brass, though it’s not much. I’ve seen some folks get creative and turn old fittings into garden art or weights for tarps, but honestly, most of it just gets scrapped. It does feel a bit wasteful, but at least it’s getting recycled instead of ending up in a landfill. If you’re in a bigger city, sometimes the municipal recycling centers will take metal plumbing parts, but it’s hit or miss.
You’re definitely not alone in wanting to avoid the mess and waste. Sometimes the best you can do is minimize it where possible and make sure the old stuff gets recycled.
I hear you on the graveyard of tools—my basement looks like a failed hardware store at this point. I’ve always wondered, though, when you’re dealing with those ancient pipes, do you try to patch things up and keep the old cast iron going, or just bite the bullet and swap everything for PVC? I keep thinking I’ll save time by just replacing the whole run, but then I remember how much fun it is to wrestle with 70-year-old fittings... Is it ever worth trying to preserve the old stuff, or am I just making more work for myself?
Honestly, I get the temptation to rip it all out and go PVC, especially after fighting with ancient threads that haven’t moved since Truman was president. But sometimes the old cast iron is still solid—patching a small section can buy you years if it’s not totally rotted. Thing is, new PVC isn’t always a magic fix either; I’ve seen folks swap everything, only to end up with leaks from rushed joints or bad glue jobs. If the old stuff’s not crumbling, I’d patch where you can and save the heavy lifting for when you really need it. Your back (and wallet) might thank you.
I hear you on the PVC hype—it’s easy to get sucked in. Last year, I tried to “modernize” my kitchen drain with all new PVC, thinking it’d be a breeze. Ended up chasing leaks for weeks because I rushed the joints. If I’d just patched the old cast iron, I probably would’ve saved myself a ton of hassle. Sometimes the old stuff really does hold up better than you’d think.

I totally get where you’re coming from. There’s something about those older materials—they might look rough, but they’ve survived decades for a reason. I’ve been tempted by the “easy” PVC route too, but I always end up second-guessing myself, especially when it comes to anything that could cause water damage down the line.
Did you use primer and glue on all your joints? I’ve heard skipping even one step can cause leaks that are a nightmare to track down. I’m always nervous about getting a perfect seal, especially in tight spaces under sinks. Sometimes I wonder if it’s worth the stress, or if calling in a pro is just safer in the long run. Not that I haven’t tried doing it myself—I just end up triple-checking everything and still worrying about slow leaks.
I had a similar situation with my bathroom drain. The original copper was ugly but solid, and I almost swapped it for PVC because “everyone” said it was easier. Ended up just cleaning it up and adding new washers. No leaks since. Makes me wonder if we sometimes overthink these upgrades.
Do you ever worry about hidden leaks with PVC? That’s my big fear—water sneaking behind walls or cabinets where you can’t see it until it’s done real damage. I guess that’s why I’m so cautious about any plumbing work. Maybe patching and leaving well enough alone isn’t such a bad thing after all...
