need some advice on plumbing stuff for DIY bathroom fix-up

Yeah, recycled fittings definitely have their quirks. I've seen a couple hold up fine, but honestly, I wouldn't gamble on them behind drywall either. Had one crack on me during a test run - thankfully before sealing the wall! Maybe they're okay if you can keep an eye on them, but for hidden stuff, proven materials just feel safer. Guess it depends how lucky you're feeling with your DIY karma...

"Maybe they're okay if you can keep an eye on them, but for hidden stuff, proven materials just feel safer."

Yeah, I get the hesitation, but isn't part of DIY about finding sustainable alternatives? Wonder if there's a reliable way to test recycled fittings beforehand... anyone tried pressure-testing setups at home?

Yeah, I totally get where you're coming from. Last summer, I helped a buddy redo his basement bathroom, and we tried using some reclaimed fittings he got from a salvage yard. We rigged up a basic pressure test using an air compressor and a gauge - nothing fancy, just capped off the ends and watched the gauge for drops. Worked okay, but honestly, it was a bit nerve-wracking. Ended up swapping out a couple fittings anyway because they looked sketchy under pressure... better safe than sorry, right?

That sounds like a pretty smart way to go about it - pressure testing reclaimed fittings is definitely gutsy. Did you guys end up using any thread sealant or tape on those older fittings, or just tighten them down and hope for the best? I've been tempted by salvage yard finds myself (prices are tempting...), but always chickened out at the last minute because of exactly what you described. Seems like there's always one fitting that looks fine at first glance but ends up being sketchy once you actually put pressure on it.

Honestly, I think your instinct was spot-on to swap out anything questionable. Plumbing isn't the place I'd want to gamble too much, especially if it's hidden behind walls or under floors. Did you notice any specific issues with corrosion or threading damage when you pulled the sketchy ones out? Curious if there's a good way to visually inspect reclaimed fittings before committing to them. Anyway, props for giving it a shot - DIY plumbing can be nerve-wracking enough even with brand-new parts.

I've had mixed luck with reclaimed fittings myself. Usually, I'll clean the threads thoroughly with a wire brush and inspect closely for hairline cracks or corrosion pits - those tiny imperfections can be sneaky. Thread sealant is my go-to rather than tape, especially on older fittings, since it fills in minor irregularities better. Did you guys notice any difference in reliability between brass and galvanized fittings? I've found brass tends to hold up better over time, but curious what your experience was.

"Thread sealant is my go-to rather than tape, especially on older fittings, since it fills in minor irregularities better."

I get why you'd prefer sealant, but honestly, I've had better luck with a combo approach - thin wrap of tape first, then a bit of sealant over it. Seems to give me fewer callbacks. Also, brass fittings are usually solid, but I've seen some cheaper ones crack under stress. Galvanized can hold up fine if they're quality-made and not exposed to constant moisture...but yeah, corrosion's always a gamble there.

I've gotta say, I'm with you on the tape-plus-sealant combo. I tried sealant alone once on some sketchy old fittings, and it ended up leaking after a week - lesson learned the soggy way, lol.

"Galvanized can hold up fine if they're quality-made and not exposed to constant moisture..."

True enough, but I've seen galvanized fittings that looked fine on the outside but were totally rusted through inside after just a few years. Brass is usually a safer bet if you ask me, just gotta avoid the cheapo brands.

Yeah, galvanized fittings can be sneaky like that. I've pulled apart pipes that looked totally solid from the outside, only to find them rusted and paper-thin inside - pretty scary when you think about it. Brass is definitely a safer choice overall, but even then, quality matters big-time. I've seen some cheap brass fittings crack or corrode way faster than you'd expect.

"Brass is usually a safer bet if you ask me, just gotta avoid the cheapo brands."

Exactly this. Spend a few extra bucks on reputable brands and you'll save yourself headaches down the road. Also, don't underestimate stainless steel fittings if you're dealing with moisture-heavy areas - they're pricier but practically bulletproof in my experience. Either way, tape-plus-sealant combo is always my go-to; learned that lesson myself after one too many midnight leak emergencies...

Yeah, galvanized pipes can really fool you. I remember tearing out some old plumbing in our basement bathroom, and from the outside everything looked totally fine. But once I got them open, it was like rust city inside - honestly surprised they hadn't burst yet. Brass is usually my go-to as well, but have you ever had issues with brass fittings getting stuck or seized after a few years? I've had a couple of those moments where I thought I'd never get the thing off again...

Stainless steel definitely sounds solid though. Haven't tried it myself because of the cost, but maybe it's worth the investment if you're doing something that'll be hidden behind walls or tile for years. Totally agree on the tape-plus-sealant combo too; learned that one the hard way after a frustrating leak that just wouldn't quit dripping no matter how tight I made things. Plumbing's tricky enough without cutting corners on fittings or sealants.

Galvanized pipes are sneaky like that, seen it myself a few times. Brass fittings can definitely seize up, especially if they're exposed to moisture or humidity long-term. Had one fitting stuck so bad I nearly stripped the threads getting it off. Stainless is pricey, but if you're burying it behind tile, might save you headaches later. Good call on the tape and sealant combo too - learned that lesson after chasing down leaks for way too long...

"Had one fitting stuck so bad I nearly stripped the threads getting it off."

Been there - had a brass fitting seize up on me last year, ended up having to carefully cut it off with a hacksaw blade. Not fun. Curious though, anyone tried using dielectric unions or fittings when transitioning between galvanized and brass or stainless? I've heard mixed opinions on whether they're worth the hassle or just another potential leak point...

Dielectric unions can definitely help, but they're not foolproof. I've seen them prevent corrosion issues pretty effectively when transitioning between galvanized and copper or brass. But honestly, the quality varies a lot by brand - cheap ones tend to leak more often, and installation technique matters too. If you overtighten or don't align them just right, you're asking for trouble down the line.

Personally, I prefer using brass nipples or fittings as a transition whenever possible. Brass seems to handle galvanic corrosion better than direct steel-to-copper connections, and it's simpler than messing with dielectric unions. But if you're dealing with aggressive water conditions or have had corrosion issues before, dielectric fittings might be worth the extra hassle. Just be careful with installation and don't skimp on quality...

Good points there - I learned the hard way about cheap dielectric unions leaking after a few months. Ended up redoing the whole connection with brass fittings, and it's been solid ever since. If you're on a tight budget, brass nipples are usually cheaper and easier to install correctly without leaks. But yeah, if your water's harsh or you've had corrosion before, spending a bit extra on quality dielectric fittings isn't a bad idea...just take your time installing them.

- Good call on brass fittings - I've seen plenty of dielectric unions fail early, even the pricier ones can sometimes disappoint. Brass is usually my go-to as well, just simpler and fewer headaches overall.

- One thing to keep in mind though: brass isn't always bulletproof either, especially if your water chemistry is really aggressive or acidic. I've had a few cases where brass fittings showed signs of corrosion after a couple years. Not common, but it happens.

- Also worth mentioning: thread sealant matters a lot. I've seen DIYers slap on way too much Teflon tape thinking more is better, then wonder why they're still getting leaks. A thin layer of good-quality pipe dope usually does the trick better (at least in my experience).

- Curious though - anyone here ever tried stainless steel fittings for residential plumbing repairs? They're pricier for sure, but I wonder if they'd hold up better long-term against corrosion issues...or if that's just overkill for typical home plumbing scenarios.

"Curious though - anyone here ever tried stainless steel fittings for residential plumbing repairs?"

Funny you mention stainless... I once had a homeowner insist on stainless fittings everywhere because he read online they'd "last forever." Well, they probably will - but his wallet sure didn't appreciate it. Honestly, brass usually does the job just fine unless your water's super aggressive. And yeah, less is more with Teflon tape - seen some DIY jobs wrapped like mummies and still leaking.

Stainless fittings can be great, but honestly they're overkill for most residential plumbing. A few thoughts:

- Stainless is pricey and usually unnecessary unless your water is really harsh or corrosive.
- Brass fittings are plenty durable for typical home use and way easier on the wallet.
- Agree on the Teflon tape - just a couple wraps does the trick. Learned that one the hard way myself after creating a mini mummy disaster under my sink...

Bottom line: stainless looks cool, but brass usually gets the job done just fine.

"Stainless is pricey and usually unnecessary unless your water is really harsh or corrosive."

Fair point, but I'm wondering if stainless might still be worth considering in certain scenarios. Like, what about bathrooms with high humidity or condensation issues - could brass fittings corrode faster there? I've seen some greenish buildup on older brass connections in damp areas... maybe stainless could actually save headaches down the road? Curious if anyone has experience with that.

I've dealt with this exact issue a few times in some older properties. Brass fittings can indeed corrode or develop that greenish patina - especially in bathrooms with poor ventilation or persistent humidity. While brass is generally durable, it's not completely immune to corrosion over the long haul, particularly if moisture is constantly present.

A few years back, I renovated a bathroom in a rental unit that had chronic condensation problems. Initially, I went with brass fittings to save costs, but after about three years, I noticed significant corrosion and buildup. Ended up replacing them with stainless steel fittings, and they've held up remarkably well since then - no visible corrosion or maintenance headaches so far.

"maybe stainless could actually save headaches down the road?"

In my experience, that's exactly right. Stainless steel might cost a bit more upfront, but if you're dealing with persistent dampness or humidity issues, it can be worth the extra investment to avoid future replacements and repairs.

Definitely agree stainless steel's the better move here. Brass fittings look nice and all, but honestly, after seeing that green crusty stuff one too many times (reminds me way too much of science class...), I'd rather pay a bit extra upfront. Did a similar swap myself last year - no regrets yet, and bonus points for fewer awkward explanations when someone notices the funky green faucet.

Stainless steel is solid, no doubt, but brass isn't always a bad call. The green crusty stuff you're talking about - yeah, it's annoying - but that's usually from cheaper brass or fittings exposed to moisture and air for ages. Quality brass fittings can hold up pretty well if they're installed right and maintained occasionally. My uncle's place has brass fixtures going on 10+ years now, and they're still looking decent. He just wipes them down every now and then with vinegar or lemon juice to keep the corrosion away. Stainless steel is definitely lower maintenance, but if someone really likes the look of brass, it's not impossible to keep it nice...just takes a bit more effort.
