Funny how the “cheap” option always ends up costing more...
Yeah, been there. Plastic’s tempting when you’re staring at the price tags, but I’ve seen too many slow leaks turn into big headaches—especially once you start messing with water pressure. If you’re running a booster pump, even minor flaws in plastic fittings can get exposed fast. My go-to now is always brass or stainless for anything under pressure. Costs more up front, but you avoid those “surprise” Saturday repairs. If you do stick with plastic, at least double-check torque specs and use proper thread sealant—hand-tight plus a quarter turn is usually safe, but overtightening cracks them in no time.
Can’t argue with that logic—plastic’s easy on the wallet, but it’s a gamble once you crank up the pressure. I’ve swapped out more cracked elbows and leaky tees than I care to remember, usually after someone tried to “save a few bucks.” Brass or stainless just holds up better, especially if you’re running a booster. Still, if you’re careful with install—don’t overtighten, use the right sealant—you can get by with plastic in low-stress spots. Just gotta weigh the risk versus reward, I guess.
Yeah, I hear you on the plastic fittings—seen way too many of those fail under pressure, especially after someone cranked down a booster pump thinking it’d be fine. It’s always the “cheap fix” that ends up costing more in the long run. I’ve had to crawl under sinks at 2am because a plastic tee decided to split and flood half a kitchen... not my idea of a good time.
Brass and stainless are just less drama, honestly. Sure, they cost more upfront, but you’re not waking up to a surprise indoor pool. That said, I get why folks use plastic for low-pressure lines or temporary setups—just gotta keep an eye on it and don’t push your luck.
If you do go with plastic, double-check your torque and use the right sealant—thread tape only goes so far. And if you’re running a booster? I’d skip the gamble and stick with metal. Peace of mind’s worth it.
I get the logic behind going metal, but man, my wallet always winces at those prices. I’ve used plastic a couple times just because it was what I could afford right then, and yeah, I’m always a little nervous about it. Had one crack on me last year—luckily just a slow leak and not a full-on flood, but still a pain. Guess it’s one of those “pay now or pay later” deals. Still, for stuff like garden lines or the laundry room where I can keep an eye on it, I’ll risk plastic if it saves me some cash. But under the kitchen sink? Not messing around there anymore... learned that lesson the hard way.

That’s a smart call. I’ve seen too many folks try to save a few bucks with plastic under sinks, only to end up with warped cabinets and water damage. Metal’s upfront cost stings, but it’s usually cheaper than replacing flooring or cabinetry down the line. For garden lines, though, I agree—plastic can be fine if you’re keeping an eye on it and don’t mind swapping it out every so often. Just make sure you’re not pushing those fittings past their pressure rating, especially if you’ve got a booster pump in play.
