Definitely agree that not every old pipe needs to go. I’ve had places where the pipes looked ancient but were still solid, and others where a “good” looking copper line had pinholes out of nowhere. Those tiny leaks are a pain—sometimes it’s just age, but I’ve heard water chemistry can speed things up, especially if you’ve got aggressive water or stray current issues. I usually check pressure and look for any greenish spots or crusty buildup as a first step before tearing into walls. It’s easy to get spooked by stories, but a little investigation goes a long way.
I get where you’re coming from, but I’ve seen too many “solid” old pipes turn into a nightmare overnight. Sure, a little green or crust doesn’t always mean disaster, but sometimes by the time you spot it, the damage is already done behind the scenes. Water chemistry is a factor, but age alone can be unpredictable—especially with galvanized or early copper. Personally, I’d rather err on the side of caution if I’m already opening up walls. Patch jobs add up fast if you keep chasing leaks one by one.

That hits home. Had a place last winter where we kept patching “just one more” leak in old galvanized lines. By the third call-out, the owner wished he’d just swapped everything while the walls were open. Sometimes it’s just not worth the gamble.
Funny how it always seems like “just one more” until you’re knee-deep in water and drywall dust. I get wanting to avoid the upfront cost of a full repipe, but with old galvanized, it’s almost like playing whack-a-mole. Ever notice how the next leak always pops up in the spot you least expect? Sometimes I wonder if it’s better to bite the bullet once, instead of nickel-and-diming it over years. Anyone else ever try epoxy lining as a middle ground, or is that just kicking the can down the road?

That’s the perfect way to put it. I’ve patched more leaks than I care to admit before finally deciding to go for a full replacement. Epoxy lining can buy you some time, but from what I’ve read, it doesn’t always address corrosion inside the pipe or stop future failures at joints. If you’re already dealing with water damage, sometimes ripping off the band-aid is just less stressful (and probably greener in the long run).
