The dip tubes in most newer water heaters should last the lifespan of the unit (8–12 years). However, some dip tubes also function as a “sacrificial anode rod”, which means it’s designed to attract all the corrosive elements in the water, ultimately protecting the tank from corrosion.

How do you replace a dip tube in a gas water heater?

Changing a dip tube is easy:

1. Cut the power to the water heater.
2. Turn the cold-water inlet valve off.
