Something about the tape acting as a lubricant and letting you overtighten, which could crack a fitting if you’re not careful. Ever run into that?
Yeah, that’s a legit concern. I’ve seen a couple of brass fittings split from being cranked down too hard—usually when both tape and dope were used. It’s easy to think “more is better” but sometimes it just leads to more trouble. I always stick to one or the other, depending on what the manufacturer says for that particular line.
About the pipe dope on plastic threads—I’ve had similar issues with older formulas turning PVC gummy. The newer stuff seems safer, but I still check the label every time. Out of curiosity, has anyone had an inspector actually call out using both tape and dope, or is it more of a “best practice” thing in your area?
I’ve wondered about that too—sometimes it feels like inspectors have their own “unwritten rules” depending on the day. Around here, I’ve never had anyone flag me for using both, but I’ve heard stories from neighbors who got dinged for it. Honestly, your approach makes sense. Manufacturers usually know best, and overdoing it just seems to invite leaks or worse. Good call on checking the label every time—those formulas change more often than you’d think.

Ain’t that the truth. I swear, one week it’s “use both,” next week it’s “never mix.” I just stick to what the label says and cross my fingers the inspector’s in a good mood. Overthinking it usually leads to a mess... or at least a headache.
Had a plumber once tell me, “If you’re not confused, you’re not paying attention.” I thought he was joking, but after three trips to the hardware store for the “right” glue, I get it now. Labels are my best friend... and sometimes my worst enemy.
I get what you mean about the labels—sometimes they’re more confusing than helpful. But honestly, I think half the time it’s just overthinking it. I used to stress about getting the “perfect” glue or fitting, but after a while, I realized most of the stuff at the hardware store will do the job if you’re not mixing up PVC with CPVC or something wild like that.
I’ve found that talking to the folks working there saves me a ton of time (and money). They usually know which glue works for what, and they’ll tell you straight up if you’re about to buy something pointless. I guess my point is, sometimes it’s less about reading every label and more about asking someone who’s seen it all before.
Not saying labels aren’t useful, but I wouldn’t trust them over a good old-fashioned conversation with someone who’s done it a hundred times.
