What Is Anode Rod In Water Heater?

Water heaters play an important role in our lives, providing us with hot water supply for various activities such as showering, cleaning, and cooking. To make sure that your water heater lasts for a longer period of time and works efficiently, you need to get familiar with anode rods. Anode rods, also known as ‘sacrificial anodes’, are an important part of any water heater unit.

They play an important role in preventing the erosion caused by electrolysis and the corrosion of the tank. In this article, we are going to discuss everything you need to know about anode rods, their functioning, and importance.

So, stay tuned, and let’s get started.

What is an Anode Rod in Water Heater?

An Anode Rod is a device used to protect water heaters from rust and corrosion.

It is installed inside the water heater tank and serves as a sacrificial anode that corrodes in order for the tank to remain safe from rust. By sacrificing itself, the anode rod helps to protect the tank from rust and reduce the need for repairs and maintenance activities. To keep your water heater running efficiently, it is important to regularly inspect and replace the anode rod.

How Does an Anode Rod Work?

An anode rod works by releasing electrons when exposed to water. These electrons attract corrosive particles and shield the metal of the water tank from corrosion.

This process is known as electrochemical corrosion and can help to prolong the life of a water heater.

Why is an Anode Rod Necessary?

An anode rod is an important part of any water heater as it helps to protect the tank from rust and corrosion. Without it, water heater tanks are more susceptible to damage from rust and corrosion, which can reduce the efficiency of the heater and cause costly breakdowns and repairs.

How Often Should an Anode Rod be Inspected and Replaced?

It is recommended that an anode rod be inspected and replaced every three to five years depending on the level of use. For households that use hard water, it is important to inspect the anode rod more regularly as hard water can quickly wear away the anode.

Signs that it’s Time to Replace Anode Rod

  • A leaking water tank or traces of water or rust around the water heater.
  • A rusty-looking water heater tank.
  • Discolored water coming out of the water heater.
  • Excess sediment in water.

How to Replace an Anode Rod

If you suspect that the anode rod in your water heater needs to be replaced, it is important to have a professional plumber inspect your tank and replace the anode if necessary. The replacement process is fairly simple and straightforward, but having a professional inspect your tank and replace the anode rod is the safest and most effective way to ensure that your water heater is properly protected from rust and corrosion.
