In this article, we’ll take you through the step-by-step process of changing the anode rod in your water heater, as well as its advantages and disadvantages. Plus, we’ve included FAQs to answer any burning questions you may have. Let’s dive in!
How to Change Anode Rod in Water Heater
Before you embark on the process of changing your anode rod, make sure you have all the necessary tools and equipment. You’ll need:
- A new anode rod that fits your water heater
- A pipe wrench or adjustable wrench
- A socket wrench
- Teflon tape
- A bucket
- A hose
Step 1: Turn off the power and water supply
Before you start working on your water heater, make sure you turn off the power supply to it by shutting off the circuit breaker or turning off the gas. Also, turn off the water supply by turning off the valve that’s connected to the cold water inlet pipe.
Step 2: Drain the water from the tank
To access the anode rod, you need to drain the water from the tank. Connect a hose to the drain valve at the bottom of the tank and place the other end of the hose in a bucket. Open the valve and let the water drain completely.
Step 3: Locate the anode rod
The anode rod is located on the top of the water heater, usually visible through a hexagonal head. Use your pipe wrench or adjustable wrench to loosen and remove the hexagonal head.
Step 4: Remove the anode rod
Once you’ve removed the hexagonal head, remove the anode rod from the water heater. If it’s difficult to remove, use a socket wrench to unscrew it.
Step 5: Replace the anode rod
Take the new anode rod and apply Teflon tape on its threads. Insert the rod into the hole where the old anode rod was removed and tighten it with the socket wrench.
Step 6: Refill the tank
Once you’ve replaced the anode rod, close the drain valve at the bottom of the tank and refill the tank with water through the cold water inlet valve.
Step 7: Turn on the power and water supply
Finally, turn on the power supply to your water heater and turn on the gas if you have a gas water heater. Also, turn on the water supply by opening the valve that’s connected to the cold water inlet pipe.

FAQs
Q1: What is an anode rod, and how does it work?
A: An anode rod is a sacrificial metal rod that’s installed inside a water heater tank to protect it from corrosion. The anode rod attracts all the corrosive elements in the water, sacrificing itself instead of the tank.
Q2: How often do I need to replace the anode rod in my water heater?
A: Anode rods typically last between 2 and 5 years. We recommend checking your anode rod once a year and replacing it if it’s deteriorated halfway or more.
Q3: Can I replace the anode rod myself, or do I need to hire a professional?
A: You can replace the anode rod yourself if you have some DIY skills. However, if you’re not confident or don’t have the necessary tools, it’s best to hire a professional plumber.
Q4: How do I know which anode rod to buy for my water heater?
A: Check your water heater’s manual or contact the manufacturer to find out which anode rod fits your model.
Q5: Can I replace the anode rod in a tankless water heater?
A: No, tankless water heaters don’t have an anode rod because they don’t store water.
Q6: Is it safe to drink water from a water heater that has a new anode rod?
A: Yes, it’s safe to drink water from a water heater that has a new anode rod. However, we recommend flushing the tank once to remove any debris or sediments from the replacement process.
Q7: How do I dispose of the old anode rod?
A: The old anode rod is made of metal and can be recycled. Contact your local recycling center or scrap metal yard to find out how to dispose of it responsibly.
Q8: Can I reuse the old anode rod?
A: No, we don’t recommend reusing the old anode rod because it’s already corroded and won’t protect your water heater effectively.
Q9: Can I replace the anode rod without draining the tank?
A: No, you need to drain the water from the tank to access the anode rod.
Q10: Can I replace the anode rod in a gas water heater myself?
A: Yes, you can replace the anode rod in a gas water heater yourself if you have the necessary tools and DIY skills. However, make sure you turn off the gas supply before starting the replacement process.
Q11: Can I replace the anode rod in an electric water heater myself?
A: Yes, you can replace the anode rod in an electric water heater yourself if you have the necessary tools and DIY skills. However, make sure you turn off the circuit breaker to the water heater before starting the replacement process.
Q12: Do I need to replace the anode rod if I have a water softener installed?
A: Yes, you still need to replace the anode rod even if you have a water softener installed. Water softeners remove minerals that can cause hardness, but they don’t eliminate all the corrosive elements that can damage your water heater.
Q13: How do I know if my anode rod needs to be replaced?
A: Check the condition of your anode rod once a year. If it’s deteriorated halfway or more, it needs to be replaced. Also, if you notice any rust or corrosion on your water heater’s tank, it’s a sign that the anode rod is no longer effective.
