When is it time to swap out old pipes?

I’ve seen that green crust turn into a pinhole leak overnight - never a good surprise. Polybutylene’s a nightmare, no argument there, but I’ve run into folks who swear theirs is “just fine” after 30 years. Sometimes I wonder if water quality plays a bigger role than people think. Ever notice if certain areas in your house have more issues than others, or is it just random?

Yeah, I’ve seen that too - one day it’s just a bit of green fuzz, next day you’re mopping up a mess. In my experience, spots near the water heater or where pipes run through uninsulated crawl spaces seem to go first. Hard water definitely speeds things up, but sometimes it feels like pure luck which section gives out. Had a job last year where only the kitchen lines were shot, rest of the house was untouched. Go figure.

Funny you mention the kitchen lines going first - I’ve seen that exact thing, and it still doesn’t make sense to me. My neighbor’s house is from the late 70s, and last winter he had a pinhole leak right above the stove. Rest of his plumbing? Not a single issue. We poked around for a bit and figured maybe it was all the extra steam from cooking, or maybe the insulation was just thinner there. Who knows.

Hard water’s a pain, but I’m not convinced it’s always the main culprit. My place has pretty soft water and I still had to replace a section behind the washing machine last year - just crumbled when I touched it. Sometimes I think it’s just a roll of the dice with these old pipes. You can baby them all you want, but when they decide to go, they go.

That’s interesting about the kitchen lines - makes me wonder if it’s just a weird coincidence or if there’s something about that area that wears pipes out faster. I’ve heard people blame everything from steam to vibrations from appliances, but honestly, sometimes it just feels random. I’m with you on the hard water thing too. We’ve got a water softener and still had to patch up a section under the bathroom sink last year. The plumber said it was probably just old age, but I can’t help but wonder if there’s a way to spot these weak spots before they go.

Has anyone tried those pipe inspection cameras? I keep seeing ads for them, but I’m not sure if they’re worth the investment or just another gadget. It’d be nice to catch a problem before it turns into a mess, especially since replacing whole lines isn’t cheap. Just trying to figure out if there’s a smarter way to handle this than waiting for the next leak...

I’ve wondered about those inspection cameras too. Part of me thinks they’re probably more useful for pros who deal with blockages or lost jewelry, but I guess if you’re really worried, it could give you some peace of mind. Honestly, sometimes it feels like pipes just pick the worst possible time to fail, no matter how careful you are. We had a pinhole leak behind our fridge last year - totally random spot, nothing around it. I guess it’s just the joy of old houses...
