How to Change a Dip Tube in a Water Heater

Common Dip Tube Issues

While metal and PEX dip tubes are available, many water heaters come with standard plastic units. These types of dip tubes can sometimes wear out quickly due to constant exposure to hot water and minerals. If your plastic dip tube becomes brittle, it may break, causing irregular water temperatures.

How to Replace a Water Heater Dip Tube

First, it is important to keep in mind that not all water heater tanks have dip tubes. Some models have the cold-water inlet placed at the bottom of the tank, eliminating the need for a dip tube. However, if your you notice the cold water coming through the middle or top of your tank, then you have a dip tube. Always put safety first, by turning off the power at the circuit breaker. Neglecting to perform this task could put yourself and others at risk of electrocution. Next, you will need to turn off the cold-water inlet valve and drain the hot water tank to get rid of any broken plastic or debris. Then you will disconnect the cold-water supply line at the top of the water heater and remove the existing dip tube with a flat screwdriver. Put the new tube into place, reconnect the cold-water supply line, and refill the tank. Turn on the hot water side of a nearby sink or bathtub to help control the release of air. When the tank is adequately filled, you can restore the power to your water heater and test the functionality of the new dip tube.
