Need some advice on choosing new plumbing fixtures

Sometimes the “ugly but safe” route just makes more sense, especially in spaces like basements where looks aren’t everything.

Had to laugh at this - I've definitely been there. In a lot of utility rooms, I’ve swapped out old foam wraps for the denim stuff. Not the prettiest, but it’s tough and doesn’t flake apart like some of the cheaper foams do. Plus, I’ve noticed less dust floating around when I’m working down there, which is a win.

Stainless fixtures have held up best for me too, especially in damp spots. I tried plastic once in a rental property and ended up replacing it after two years - just didn’t hold up to the wear and tear. Sometimes function really does have to come first, even if it means things look a bit industrial. If it keeps the air cleaner and saves me from extra repairs down the line, I’ll take it.

Funny you mention the denim wraps - I've been using those too, and while they’re not winning any beauty contests, they really do cut down on the mess. I’ve also found that stainless is worth the upfront cost, especially in areas that get damp or see a lot of use.

One thing I’ve been debating is whether it’s worth paying extra for brass valves over stainless ball valves. Brass seems to last forever, but it’s not always easy to find the right fittings without special ordering. Anyone else run into issues with corrosion or compatibility between metals? I’ve heard mixed things about mixing brass and stainless in the same system, but haven’t had any major problems yet myself... Just curious if anyone’s had long-term headaches from that combo.

Honestly, I’ve wondered about this too. I’ve read that mixing metals can sometimes cause galvanic corrosion, especially if there’s any moisture hanging around. That said, I’ve got a couple spots where brass valves meet stainless and, knock on wood, nothing’s gone wrong after a few years. Still, I always get a little nervous about long-term stuff - hate the idea of hidden leaks. I do like how solid brass feels, but man, the price and hassle of finding the right fittings is real. Sometimes I just stick with stainless all the way for peace of mind, even if it’s a bit overkill.

Totally get that. My wallet cries every time I price out brass. Here’s my cheapo method: if I have to mix, I slap on a dab of pipe dope and cross my fingers. Not exactly textbook, but hey, it’s held up so far... Just keep an eye out for any green fuzz or weird leaks under the sink. If you’re losing sleep over it, stainless all the way is definitely less stressful (but more painful at checkout).

Yeah, I’ve gone the “hope for the best” route more than once. Did a bathroom reno last year - ended up with a Frankenstein of brass and stainless under the sink. Used Teflon tape and checked for leaks every day for a week. No issues yet, but I still get nervous when I see that green corrosion starting. Stainless is great, but man, those fittings add up fast.

Mixing metals under the sink always makes me a little uneasy too, but sometimes you just gotta work with what you’ve got. I get the appeal of stainless - super durable - but my wallet usually steers me toward brass or even plastic if it’s not under a ton of pressure. Anyone here actually had a mixed-metal setup fail, or is the corrosion mostly just cosmetic? I keep hearing horror stories but haven’t seen a real disaster yet...

I’ve mixed metals under my kitchen sink more times than I’d like to admit, mostly out of laziness or because the hardware store was out of what I needed. Never had a catastrophic leak - just some crusty green stuff on the fittings after a while. Honestly, it’s uglier than it is dangerous in my experience, unless you’re dealing with really old pipes or super hard water.

Mixing metals isn’t the end of the world, but I’ve learned to avoid it when possible, especially in rentals. That “crusty green stuff” you mentioned -

just some crusty green stuff on the fittings after a while

1. Stick to one metal type per run if I can.
2. If I have to mix, use dielectric unions between copper and steel.
3. Check for leaks every few months, especially in older units.

It’s not always pretty, but it saves headaches down the line. Hard water definitely speeds things up, too.

Yeah, that green buildup is classic galvanic corrosion - seen it plenty, especially where someone’s swapped a valve or fitting and mixed metals without thinking. Dielectric unions help, but honestly, I’ve seen even those fail if the water’s really aggressive or the install’s sloppy. Hard water’s brutal for this stuff, you’re right. One trick I picked up: if you’re forced to mix, at least keep the runs short and joints accessible. Makes it way easier to catch problems before they turn into a mess.

Definitely ran into this when I replaced a section of pipe in my basement last year. Here’s what I learned the hard way:

- Swapped in a brass fitting between copper and galvanized, thinking it’d be fine. Nope - green gunk everywhere in six months.
- Dielectric unions did help, but only after I redid the joint and actually tightened everything properly (first time was a bit sloppy).
- Water here is super hard - honestly, I wish I’d just stuck with all copper to begin with. Mixing metals seems like asking for trouble unless you’re really careful.
- If you’re trying to save some cash, check local salvage yards for solid copper fittings. Found a few that way and they’ve held up great.

Just my two cents... sometimes cutting corners ends up costing more down the line.

Mixing metals is always a gamble, especially with hard water. I’ve seen that “green gunk” you mentioned - once it starts, it’s tough to stop. Honestly, I’m not convinced dielectric unions are a cure-all; they help, but if the joint isn’t perfect or the water’s aggressive, issues creep back in. I get wanting to save money, but salvaged copper can be hit or miss too. If you’re going to the trouble, sometimes just biting the bullet and buying new copper is worth the peace of mind. Cutting corners on plumbing feels like tempting fate...

Yeah, mixing metals is one of those things that sounds fine until you’re cleaning up a mess under the sink at 2am. I tried using salvaged copper once - looked okay, but the wall thickness was way off and it didn’t solder right. If you’re already elbows-deep, new copper’s not a bad call. Sometimes the “cheap” route costs more in the long run…

I get where you’re coming from - mixing metals can definitely be a headache, especially if you’re dealing with older plumbing. That said, I wouldn’t rule out salvaged copper entirely. Sometimes the issue’s less about the material and more about prep work. If the wall thickness is off, sure, that’s a nonstarter, but in my experience, cleaning and reaming the ends thoroughly can make a world of difference with solder joints.

Sometimes the “cheap” route costs more in the long run…

That’s true in a lot of cases, but it depends on what you’re salvaging and how you’re using it. For example, I’ve had decent luck reusing copper from demo jobs for short runs or repairs behind walls where matching aesthetics isn’t a concern. It does take extra time to inspect for pitting or corrosion, though.

New copper is definitely more predictable, but with prices these days... I get why folks look for alternatives. Just comes down to whether you’ve got time to double-check your materials or need peace of mind at 2am under the sink.

Sometimes the “cheap” route costs more in the long run…

That’s what I keep hearing from the old-timers at work, and honestly, I get it. I’ve seen some “budget” repairs turn into full-on disasters because someone tried to save a few bucks on pipe. But is there a trick to spotting good salvaged copper? Like, if it looks clean and isn’t pitted, is that enough? Or am I missing something that’ll bite me later? I’m always worried about hidden corrosion or weak spots. Maybe I’m just paranoid after seeing one too many leaks at 3am...

I hear you on the paranoia - nothing like a 3am leak to make you second-guess every shortcut. I’ve tried salvaged copper before, and even when it looked fine, I ended up with pinhole leaks a year later. Sometimes the inside’s corroded even if the outside looks perfect. I’d say if you’re not 100% sure where it came from or how it was used, new pipe is worth the peace of mind. That said, I know some folks swear by reusing old stuff... but my nerves can’t handle another midnight flood.

- Totally get the anxiety about leaks - my first week in this place, I woke up to a dripping ceiling.
- I’ve been debating new vs. salvaged pipe too. The idea of saving money is tempting, but I don’t want to gamble with hidden corrosion either.
- Did you notice any big difference in water pressure or taste after switching to all new pipes? Trying to decide if it’s worth the upgrade everywhere, or just for the worst sections.

The idea of saving money is tempting, but I don’t want to gamble with hidden corrosion either.

Honestly, I’ve seen folks regret going with salvaged pipe more than once - corrosion can be sneaky. When I swapped out old galvanized for new copper in my last place, the water pressure jumped and the weird metallic taste vanished. Not saying you need to gut everything, but even just replacing the worst stretches made a noticeable difference for me. Sometimes peace of mind is worth a little extra up front.

I get the temptation to save a few bucks, but I’ve seen what happens when “hidden corrosion” comes back to bite you.

corrosion can be sneaky

Corrosion really is one of those things you don’t notice until it’s a much bigger problem. I’ve had tenants call about “just a little drip” that turned out to be a corroded pipe ready to burst. I get wanting to save where you can, but I always ask myself - what’s the cost if I have to open up a finished wall later? Sometimes it’s worth biting the bullet and replacing more than you think you need to. Have you looked into PEX as an option? It’s not perfect, but it’s saved me some headaches compared to old copper.

PEX is a game changer, honestly. I swapped out some old galvanized pipes last year and haven’t looked back - no more mystery leaks or green gunk. Plus, it’s way easier to snake through tight spots. Only thing is, I do wonder about the plastic long-term... but at least I’m not busting open walls every few years. If you’re picking fixtures too, maybe check for WaterSense labels? Saves water and money, and you don’t have to feel guilty about those extra-long showers.
