Top 10 Best Anode Rod For Softened Water (Updated in 2022)

If your home water system has a tank-style water heating system, there is a high possibility that it comes with an anode rod.

Best Anode Rod For Softened Water

The water heater lining in a water heater system is prone to corrosion.

An anode rod is added as a sacrificial element so that it corrodes instead of the water heater lining.

Softened water uses an anode rod that is constructed out of steel, aluminum, and magnesium.

Some anode rods also come with a zinc coating at times.

You must get the right kind of anode rod because tap water often contains minerals that eat the heater lining. And as the anode rod sacrifices itself, it will need to be replaced often as well.

If you are looking for the best anode rod for softened water, you’ve come to the right place. Down below we have listed a few of the top anode rods in the market.

Advantages Of Using Anode Rod

No heating system can operate without an anode rod. But why is this part so important? Let’s find out.

1. It Increases The Lifespan Of A Heater

The main task of an anode rod is to protect a water heater from corroding.
A water tank consists of water, heat, and steel. This is the perfect recipe for corrosion. A water heater, when placed in this situation, is bound to rust.

Here, an anode rod will sacrifice itself by rusting in place of the water heater. It does so by attracting corrosive minerals. These minerals eat away at the flexible anode rods and therefore the rod keeps on reducing itself.

When the rod erodes, it gives out electrons into the water tank which prevents it from rusting.

As a water heater is a very expensive thing to replace, the anode rod saves you the bucks. You just have to replace the anode rod from time to time.

2. Reduces Smell

The sulfur bacteria in water will feed on sulfur in your water tank. This produces hydrogen sulfur gas that in turn gives out a very off-putting smell.

An anode rod will also react with the sulfur bacteria in water and eliminate it. In fact, it can get rid of the off-putting smell for years.
