Do you think the UV-resistant stuff actually helps, or is it just marketing?
I’ve tried the UV-rated PEX and honestly, it’s better than regular, but still not invincible. If you’re running lines outside or near windows, I’d still cover it or use copper. Sun just eats plastic over time, no matter what the label says. Learned that the hard way with a garden hose setup—cracked after one summer. Copper’s more work, but you don’t have to babysit it.
- Totally hear you on the UV-rated PEX. It’s better, but yeah, it’s not magic.
- Learned that lesson after a quick fix on a rooftop AC line…thought the UV label meant I could leave it exposed. Nope. Brittle in under a year.
- Copper’s a pain to install, but man, once it’s in, you can almost forget about it.
- If you’re set on PEX, I’d at least slap some insulation or conduit over it. Even a cheap foam sleeve helps.
- Gotta say, you’re doing the right thing thinking long-term instead of just trusting the marketing.
Yeah, I learned the hard way with PEX too—ran a line across the south wall for a “temporary” solar preheat setup, didn’t bother with conduit. By spring, it was chalky and brittle. Insulation’s cheap compared to redoing the whole thing. You’re spot on thinking about durability up front.
Yeah, I hear you on the PEX—those things just don’t hold up to the sun like you’d hope. I had a similar situation with a tenant who thought they’d help out and “fix” a line on their own. Left it exposed, and by the time I noticed, it was a mess. Ended up costing way more than if I’d just done it right from the start.
I get wanting to save a few bucks or thinking, “Eh, it’s just temporary,” but man, those shortcuts always come back to bite. Insulation’s one of those things that feels boring to spend money on, but when you factor in redoing the whole setup—or worse, dealing with leaks in the wall—it’s a no-brainer.
Still, gotta give you credit for jumping into solar preheat stuff. It’s intimidating at first, but once you’ve had a couple of these mishaps, you really start thinking long-term. Live and learn, right?
Yeah, that “just temporary” thinking gets me every time. I once tried to rig up a quick fix with some leftover foam pipe wrap and duct tape—thought I was being clever. Next summer, the sun just ate right through it, and the PEX turned brittle. Lesson learned: the sun’s no joke, especially on those south-facing runs.
I’ve been eyeing those solar preheat kits too, but the price tags kind of freak me out. Wondering if it’s worth piecing together something DIY with copper tubing and a bit of elbow grease, or if that’s just asking for more headaches down the line. Anyone ever try the black hose-in-a-box trick? Curious how well it really works for a family, not just a weekend cabin...
