I've definitely noticed pipe material makes a difference. About two years ago, I had this old galvanized steel pipe in my basement that started dripping out of nowhere. Nothing major, just a slow, frustrating drip that was driving me nuts. Anyway, I tried the usual plumber's tape—wrapped it carefully, snugged it up tight—but no luck. It slowed down but didn't completely stop.
A buddy of mine who's a bit more experienced with plumbing suggested using pipe dope along with the tape. Honestly, I was hesitant at first because I'd always heard tape alone was enough, and adding another layer seemed like overkill. But after a weekend of that relentless drip, I figured "why not?"
The combo method worked like a charm. I don't know if it was because the threads were worn or maybe galvanized steel just responds better to the extra sealing compound, but it stopped leaking immediately and hasn't dripped since. On the other hand, I've redone some copper fittings recently (installed a new laundry room sink last summer), and tape alone was totally sufficient. Maybe copper threads are smoother or something? I'm no expert, just guessing here.
One thing I've learned through trial and error is to always be cautious with older galvanized pipes—sometimes they're rusted or brittle inside, and overtightening can lead to bigger headaches. I guess my point is, sometimes it's less about the materials you use and more about understanding the quirks of your particular plumbing setup and material. Every home's plumbing seems to have its own personality, doesn't it?

Couldn't agree more with this part. But honestly, I've found pipe dope alone usually does the trick better than tape, especially on older galvanized pipes. Tape can sometimes bunch up or tear if the threads are rough or corroded. Learned that the hard way after a frustrating weekend of leaks... Now I just stick with pipe dope for galvanized and save the tape for copper or brass fittings.
"Tape can sometimes bunch up or tear if the threads are rough or corroded."
Yeah, been there myself... Tape can be a pain on older pipes. Pipe dope definitely works better on galvanized fittings, but I've found that using both—thin layer of tape first, then pipe dope—can give you an extra bit of insurance if you're dealing with really stubborn threads. But hey, whatever keeps your pipes leak-free and your sanity intact is a win in my book.
I've had decent luck with just tape on newer fittings, but older galvanized pipes can really test your patience. Had a tenant call me at midnight once because a taped joint decided to drip out of nowhere... lesson learned. Now I always go for the combo method—thin tape first, then pipe dope on top. Might seem like overkill, but it beats dealing with midnight plumbing adventures.
Haha, midnight plumbing adventures are the worst...been there, done that. I usually stick with tape myself, but now you've got me reconsidering. Ever tried the combo on PVC fittings too, or just metal?
