Fits all residential water heaters with 3/4-inch plumbing. Heaters of 75 gallons and greater often have bigger plumbing. Please specify your tank height from the cover to the drain valve when ordering.

This is one of the places waterheaterrescue.com shines. Few offer curved dip tubes to expel sediment and we're the only one to custom-bend them to fit your tank!

IMPORTANT! If you have an electric water heater made after April 2015 by A.O. Smith, State, Kenmore, Reliance, American, Maytag or Whirlpool; or any Rheem, Ruud, Richmond, or GE made after that date, let us know because you'll need a dip tube with a pipe nipple longer than four inches.
