What Is A Dip Tube?
A dip tube is a plastic tube in your water heater that brings the cold water into the bottom of the heater. The dip tube is designed to prevent incoming cold water from mixing with existing hot water.

Some of the dip tubes manufactured by Perfection Corporation and supplied to most major water heater manufacturers between August, 1993 and October, 1996 were made of plastic and are now disintegrating.

Signs Of A Defective Dip Tube

Loss of hot water pressure
Low hot water temperatures
Appearance of tiny white or gray particles in your hot water

Put Your Dip Tube To The Test
Unscrew the aerator at one of your faucets to see if you notice white or gray particles. If you do, put the particles in a capful of vinegar. If the particles dissolve, they are calcium buildups. If they do not dissolve, you have a defective dip tube. PLEASE NOTE: This is only one way to determine if a dip tube is defective. Lack of particles does not mean your dip tube is functioning properly.
