What size anode rod do I need?

Most gas or electric water heaters require a standard rod length of 44”. On some tall electric or solar storage tanks a rod 51” in length would be required.

Correspondingly, are anode rods standard size?

A: An anode rod is aluminum or magnesium cast around a steel core wire and hex head. For residential-type heaters, all anodes are the same diameter -- 3/4-inch. If you have a 30-gallon or what they call a low-boy -- a short, broad 40-gallon, you might have to shorten it.

Secondly, which is better magnesium or aluminum anode rod? For harder water an aluminum anode rod is the best choice for your heater and if you live in an area with soft water then a magnesium anode rod is your best choice. Aluminum anodes tend to be cheaper than magnesium anode rods. A magnesium rod will generally last less than an aluminum rod.

In this regard, how long should an anode rod be?

Anode rods generally can last about three to five years but it really depends mostly on the quality of your water and how much water travels through your water heater.

Which anode rod do I need?

Aluminum anode rods are best for places with hard water. The aluminum rod will withstand harder water better than a magnesium or zinc rod. Zinc anode rods are designed to eliminate or reduce the sulphur or rotten egg smell present. A Zinc anode rod made from a combination of aluminum and zinc.

Do you need an anode rod?

The reason an Anode Rod is required by a Suburban Water Heater is because the tank of the Suburban Water Heater uses glass enamel over a steel tank. If the enamel cracks for any reason it will expose the steel to the water and the steel will start to corrode even from a pinhole in the enamel.

Are water heater anode rods universal?

Are water heater anode rods universal? Pretty much, yes. If you wish to check it: First start with the owners manual of your water heater. Never throw it away.

Can anode rods be cut?

You can cut the anode rod to the length you need. The best way to cut the anode rod is with a hacksaw. Use a file to smooth the cut and install the rod.

Are there different types of anode rods?

There are several options for replacing your anode rod, with magnesium, aluminum, or a combination of aluminum, zinc and tin being the most common anode rod materials. (Most water heaters come with an aluminum rod as standard equipment.)

How much does a anode rod cost?

Anode Rod - $20-$50 Plumbers suggest getting a new anode rod every five years. The rod itself is only $20-$50 and, with proper instructions and precautions, you can perform this maintenance on your own. The anode rod keeps the inside of your tank from corroding. It does so by drawing the corrosion to itself.

How often do you change anode rods?

every 6 years

What do anode rods do?

Protecting Your Water Heater The anode rod is a piece designed to slow down corrosion and rusting in water heaters. When water corrodes the magnesium, the anode rod releases electrons into the tank which form a protective barrier around the steel of the tank.

Is it too late to replace anode rod?

Anode rods are made of either magnesium or an aluminum-zinc alloy. The downside is that if you wait too long to replace the anode rod, it may be too late. If more than five years has passed, it may be too late to save the water heater.

Can you clean an anode rod?

Can You Clean an Anode Rod? You cannot clean your anode rod in your water heater . However, it is important to inspect the sacrificial anode rod every 1 to 3 years and replace it after more than 50% of its wear and tear to avoid corrosion of your tank.

Do electric anode rods work?

When your water gets a sulfur smell, it often involves the anode rod in your hot water heater. This rod is designed to attract corrosive elements, extending the life of your heater.

Anode Rod Comparison.

Powered Anode Rod	Normal Sacrificial Anode Rod
Antibacteria Effectiveness	Excellent	Moderate/Excellent for zinc rods

Why does my hot water smell like rotten eggs?

The most common cause of smelly water is anaerobic bacteria that exist in some water and react with sulfur and the magnesium and aluminum sacrificial anodes that come with most water heaters to produce hydrogen sulfide gas, making the classic rotten egg odor.

How does an anode work?

Sacrificial anodes are used to protect metal structures from corroding. Sacrificial anodes work by oxidizing more quickly than the metal it is protecting, being consumed completely before the other metal reacts with the electrolytes. Three metals that can be used as sacrificial anodes are zinc, aluminum, and magnesium.

How do I extend the life of my water heater?

Get Familiar With Your Water Heater Maintenance Schedule

Test the temperature relief valve at least once per year.
Flush your water heater every 4 months.
Clean your water heater tank once per year.
Replace your anode rod every 2-5 years.
For gas water heaters: check the burner every year.

How long does a sacrificial anode last?

The most active metal (zinc for example) becomes the anode to the others and sacrifices itself by corroding (giving up metal) to protect the cathode - hence the term sacrificial anode. The sacrificial anode would last between 130 and 150 days.

Do I need an anode in my water heater?

The Anode Rod: A Mysterious but Necessary Water Heater Component. It prevents rust in your water heater's tank, and to do so effectively it needs to be replaced every two to three years by professional Littleton, CO plumbers. Otherwise, your water heater can absolutely require premature replacement.

Can you cut a magnesium anode rod?

You can cut your sacrificial anode, whether it is magnesium or aluminum, in order to replace it. To do this, use a pair of gloves and a saw and cut as you remove the old anode.
