As a retired plumber, I can assure you I used either pipe dope or Teflon tape on every threaded joint.....it just eases the threading of the joint, making for a tight, leak free connection. Sorry, didn't mean to start a big thing. Also, "technically speaking," one should not apply either product to the first couple of threads to keep the "stuff" out of a potable water system...okay, I'm done!
