Making Sure Your Home’s Pipes Are Up To Code—How I Do It
Curious if you’ve ever run into issues with old galvanized pipes? I keep finding them in 60s-era homes and they’re always half clogged with rust. Wondering if you bother descaling or just replace when you find them...
I’m right there with you on the old galvanized stuff. My place was built in ’68 and I swear every time I open a wall, it’s like a time capsule of questionable plumbing decisions. I tried descaling one section (vinegar flush, some elbow grease), but honestly, it felt like putting a band-aid on a broken leg. Ended up replacing the worst runs with PEX—way less stress in the long run. Still, I get nervous about what’s lurking behind the drywall...

That’s exactly how I feel about descaling old galvanized. You might get a trickle more flow for a bit, but those pipes are just ticking time bombs. I’ve seen folks try to stretch their luck and end up with leaks in the walls months later. PEX is the way to go—cheaper in the long run, and you’re not constantly worrying about what’s rusting away behind your shower. The only catch is, sometimes you open up a wall and find even scarier stuff... like electrical taped with masking tape.

Yeah, that’s the part folks don’t always expect. Pipes are one thing, but once you start demo, all bets are off. I’ve seen knob-and-tube spliced with lamp cord—makes old galvanized look like the least of your worries. When you switched to PEX, did you run into any weird code issues with existing connections? Some of these older houses have “creative” plumbing solutions...
I hear you on the “creative” plumbing—my place had copper lines patched with random PVC bits and a mystery adhesive. When I swapped to PEX, the inspector flagged a few old saddle valves still lurking under the sink. Not a huge deal, but it’s wild what gets buried in these walls. Sometimes I wonder if previous owners just made it up as they went along...
I get where you’re coming from, but honestly, I don’t think it’s always just previous owners winging it. Sometimes it’s whoever they hired trying to save a buck or just doing what was “normal” back then. I’ve opened up walls in places built in the 70s and found all sorts of weird stuff—galvanized pipe spliced into copper with nothing but a bit of tape and hope. But back then, nobody blinked at it.
Saddle valves are a pain, though. I always pull them out when I find them, even if they’re not leaking yet. They’re just waiting to cause trouble down the line. I wouldn’t say it’s wild so much as just... typical for older homes. If you want everything up to code, you pretty much have to gut and redo it all, which isn’t always practical unless you’re already renovating. Sometimes you just have to pick your battles and keep an eye on the trouble spots.
