Yeah, galvanized is always a headache—every time I open up a wall and spot it, I know there’s gonna be rust or some weird buildup. I’m with you on push-to-connects being a bit sketchy for anything hidden. They’re fine for a quick fix under a sink, but I’d never trust them behind finished drywall. Crimped PEX seems to be the sweet spot lately—less drama, and it doesn’t mess with the aesthetics if you ever have to open things up again. Copper’s classic, but man, it’s not always worth the hassle unless you’re going for that old-school charm.
Crimped PEX really does hit that sweet spot, especially if you’re trying to keep things green and efficient. I do kinda miss the look of copper, but man, the energy and resources that go into mining and producing it… not ideal. PEX also doesn’t corrode like galvanized or copper, which means less junk leaching into your water over time. I get the hesitation about push-to-connects too—seems like a shortcut, and shortcuts behind walls make me nervous.
I hear you on the copper nostalgia—there’s just something about those old pipes. But honestly, after dealing with pinhole leaks in my 1920s place, I’m all for PEX now. Crimped connections feel way more trustworthy than push-to-connects, especially behind plaster walls. Less stress about future repairs, too.
I get the appeal of PEX—especially when you’ve had to patch up ancient copper more times than you can count. But I’ll admit, there’s a part of me that still leans toward copper, even with its quirks. Maybe it’s just the designer in me, but I love how copper ages. I once worked on a brownstone where the exposed copper pipes became this accidental design feature—warm, a little bit industrial, and honestly kind of beautiful.
That said, I totally get the stress about leaks behind walls. PEX is forgiving, and those long runs make for fewer joints (less risk, in theory). Still, I’ve seen some PEX installs that looked a little... wobbly? Maybe it’s just the way some folks rush through jobs these days. With copper, at least you know it’s not going anywhere if it’s done right.
Guess it comes down to what you value more—peace of mind or a bit of old-school charm. For me, if the pipes are visible or part of the vibe, I’ll always try to keep the copper. Hidden away? Yeah, PEX makes life easier.
How Long Do Pipes Really Last Under Pressure?
Copper definitely has that “timeless” look, especially when it’s exposed. I get the appeal—there’s something about those greenish streaks and the way it catches the light in an old house. But if we’re talking about how long pipes last under pressure, there are a few things I’ve picked up from tearing into walls and crawling under floors over the years.
Here’s how I break it down:
1. **Copper:** If you’ve got good water (not too acidic or hard), copper can easily go 50+ years, sometimes even pushing 70. The catch is, it really depends on the quality of the install and the water chemistry. I’ve seen pinhole leaks in 20-year-old copper where the water was aggressive, and I’ve also pulled out 80-year-old lines that looked almost new inside. Solder joints are usually the weak point—if they’re done right, they’ll outlast most of us, but a cold joint or too much flux can be trouble down the line.
2. **PEX:** Most manufacturers rate PEX for 40-50 years, but it hasn’t been around as long as copper, so we’re all kind of waiting to see if it lives up to that. It handles pressure surges better than copper (it flexes instead of splitting), but UV light is its kryptonite—leave it exposed to sunlight and you’ll have problems fast. The fittings are usually where leaks happen, especially if someone cuts corners or uses cheap crimp rings.
3. **Pressure:** Both materials are rated for typical household pressures (usually up to 80 psi), but if your system spikes above that—say from a faulty pressure regulator—either one can fail early. I always recommend putting in a pressure gauge and checking once in a while. Cheap insurance.
4. **Install Quality:** This is huge. A wobbly PEX job or poorly supported copper will both give you headaches eventually. I always use pipe supports every 32” for PEX and every 6-8’ for copper (closer at turns). And with PEX, making sure there’s no kinking during install is key.
If you’re after peace of mind behind walls, PEX is hard to beat for ease and fewer joints. But for anything visible—or if you just like working with metal—copper’s still got a lot going for it. Personally, I mix and match: PEX in the walls, copper where it shows. Keeps everyone happy... including me when I have to fix something later.
One last thing: whatever you pick, don’t skip on the pressure test before closing up walls. Nothing worse than finding out about a leak after you’ve patched and painted. Learned that one the hard way...
