Pipe Dope vs Teflon Tape


Is their a reason for using pipe dope over teflon tape on water connections? I just had a helluva time cracking loose a couple of threaded on valves that were gooped up with a heavy load of that cheap white sticky pipe dope.

Why do plumbers use that stuff? Seriously, is it just because it is cheap and easy? I know teflon tape takes a little more time, but sure comes in handy 10 years later when you need to remove it.

I've had far less leaks with teflon dope. When it gets wipe off there no loose strings or a white ring like with tape, there's no way to put it on backwards.

Why I prefer dope (pipe dope that is)
When I drop a can of pipe dope I simply pick it up and continue on
When I drop a roll of tape i have to chase it across the room and then have my apprentice roll it back up..
When I screw pipe together I don't plan on taking it apart.
The best use I've found for tape is tying it to a electricians trailer ball and watching him drive away at quitting time with a 30' tail

I prefer pipe dope, but some swear by tape and others like using both. It really comes down to preference. Not all dopes are the same either. On gas applications, the white and blue stuff turns to concrete and the black stuff is like using JB Weld; horrible stuff, I usually go straight to the 24's when I come across it.

so, the consensus is that plumbers like the dope. maybe it is just the really nasty cheap white crap used in my house that has the consistency of salt water taffy. i have some rector seal stuff that is yellowish, doesn't seem nearly as bad.
