What is a water heater dip tube?
A water heater dip tube is a long plastic tube that extends from the cold water inlet down to the bottom of the water heater tank. Its purpose is to distribute cold water evenly throughout the tank, preventing hot water from being mixed with cold water as it enters the tank.
Why replace a water heater dip tube with a plastic one?

Turn off the power or gas supply to the water heater

Remove the old dip tube
Once the tank is drained, you can remove the old dip tube. Depending on the make and model of your water heater, the dip tube may be secured in place with a threaded fitting or a clip. Use a wrench or pliers to loosen and remove the fitting or clip, then pull the dip tube out of the tank.
Install the new plastic dip tube

Refill the tank
After the new dip tube is installed, close the drain valve and turn on the cold water supply valve. Allow the water heater tank to refill with water.
Restore power or gas supply
Once the tank is full, you can restore power or gas supply to the water heater.
Test the water heater
Finally, you will want to test your water heater to ensure that it is working properly. Turn on a hot water faucet and allow the water to run for a few minutes to ensure that the water is flowing properly and that there are no leaks.
