I’ve had fittings that just refused to cooperate, no matter what combo I threw at them—grease, tape, even a bit of wishful thinking. Honestly, I’m not convinced mixing both is always the best route. Sometimes the grease makes the tape slip, or the tape bunches up and you end up with a worse seal than if you’d just picked one. I usually stick to tape for sealing, maybe a dab of thread sealant if it’s stubborn, but I try to keep grease away unless the threads are really rough.
Had a job last month where I tried both because the threads were borderline stripped. Ended up redoing it twice because the tape wouldn’t stay put. Ever notice how these “simple” installs can eat up your whole afternoon? Makes you wonder if the manufacturers ever actually try installing their own products...

That right there hits home. Last week I was wrestling with a so-called “universal” sprayer kit that was supposed to be a 10-minute job. Ended up taking me close to an hour just to get the threads to seal. I’ve never had much luck mixing grease and tape either—usually just makes a mess and, like you said, the tape slides around or bunches up. I stick with tape 90% of the time, and if the threads are chewed up, I’ll use a bit of liquid thread sealant. Grease is more for when I’m worried about galling or if I know I’ll need to take it apart again soon.
One thing I’ve noticed with some of these newer fittings is the tolerances are all over the place. Sometimes you get a nice snug fit, other times it feels like you’re threading a garden hose onto a fire hydrant. Had one where the nut just spun and spun—no bite at all. Ended up wrapping the male threads with extra tape, but even then it felt sketchy.
I get why folks want to double up on sealants when things aren’t going right, but in my experience, less is usually more. Too much goop and you’re just fighting your own work. And yeah, those “quick install” claims are usually good for a laugh... or a headache.
Wouldn’t mind seeing a manufacturer actually try to install one of these things straight out of the box, using just what they provide. Bet they’d be surprised how often things don’t line up like they do in the manual.

I get where you’re coming from, but I’ve actually had a few stubborn leaks that only stopped after I doubled up—tape plus a dab of pipe dope. Sometimes those “less is more” rules go out the window if the threads are junk. Not ideal, but it’s saved me from a call-back more than once.
Honestly, I get nervous about mixing both unless the manufacturer specifically says it’s okay. I’ve seen some threads where too much stuff just makes it worse—like, you end up with a clog or a mess that’s hard to clean up later. Has anyone run into issues with warranty claims getting denied because of “improper sealant use”? Just curious if that’s ever bitten someone.
I get where you’re coming from, but honestly, I’ve mixed plumber’s putty and Teflon tape a couple times when I was in “just make it stop leaking” mode. Never had a warranty issue, but maybe I just got lucky or the toilet gods were smiling on me. Sometimes it’s more about not overdoing it—like, don’t go full peanut butter sandwich with the sealant.
