  • When the tub spout has to fit using a slip-on installation process a 1/2 nominal copper tube must be used for that installation to work making sure it stays put by attaching with a screw.
  • If the spout needs to be attached to an iron pipe then tape to the pipe using Teflon tape and secure by screwing together at the pipe nipple.
  • For a copper sweat installation, you will need to solder the spout to the copper pipe after carefully removing the O ring, tighten the spout gently by hand until it is against the bathroom wall.
