What type of anode rod should I use?

What type of anode rod should I use?

Magnesium anode rods are expected to work better in a home with soft water. Aluminum anodes are appropriate for homes with hard water and a high PH. Zinc anodes work best if a home is starting to smell like rotten eggs and is best for replacing water heaters that already dissolved.

Are anode rods all the same?

All anode rods have essentially the same design, namely a steel core wire surrounded by a sacrificial metal. Different types of rods use different types of metals for different purposes and benefits: Magnesium: This is probably the most common type of anode rod.

Which anode Rob material is best?

The two main factors that contribute to anode activity are anode material, and water chemistry. The Anode: Magnesium is a leading anode material given its ability to best protect the steel tank. It “gives up” electrons more freely than aluminum.

How do I know what size anode rod to buy?

As a rule you want the anode to be “tip to toe” running the full height or length of the tank. If you cant see your brand on the chart then just measure the length of the tank and pick the closest length of anode. If the anode is too long they can be simply cut to length with a hack saw.

Which is better zinc or aluminum anodes?

These “mil spec” aluminum anodes are more electrically active and protect better than zinc, plus they last longer! Aluminum anodes also use a much less toxic activator – which makes them better for the environment. To top it off, aluminum anodes are really the only choice that will work in both brackish AND salt water.

How much does it cost to replace an anode rod?

An anode rod costs about $50. Some homeowners may feel comfortable replacing it themselves. If not, call a professional plumber, who can assist. The cost of having it replaced professionally may be around $250 or $300.

Which is the best anode rod for well water?

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.

Which is better magnesium anode rods or aluminum anodes?

Unlike aluminum anode rods, dissolved magnesium offers health benefits. Magnesium rods are more expensive. Reaction with water elements can sometimes lead to production of hydrogen sulfide which comes out as a rotten-egg smell in the water. Aluminum anode rods are cheaper than magnesium anode rods.

How long do aluminum anode rods last for?

An aluminum anode rod will last about five years. In some cases, aluminum anode rods can cause odors, but this is more of a problem with magnesium. Aluminum rods can get a build up of corrosive materials on them.

Which is the longest lasting water heater anode rod?

Aluminum is the longest-lasting and least expensive option. Magnesium will corrode slightly faster than aluminum, but there are health benefits to drinking water with dissolved magnesium.

What type of anode rod should I use?

What type of anode rod should I use?

Magnesium anode rods are expected to work better in a home with soft water. Aluminum anodes are appropriate for homes with hard water and a high PH. Zinc anodes work best if a home is starting to smell like rotten eggs and is best for replacing water heaters that already dissolved.

Are all water heater anode rods the same?

Anode rods are not universal. Anode rods vary in length and material. Some anode rods are installed at the top of the water heater tank, while others are attached to the hot water outlet.

Where is the anode rod on a Whirlpool water heater?

The anode rod in your Whirlpool water heater is located on top of your tank. When you are facing the front of your water heater, the sacrificial magnesium or aluminum anode is on your right. Refer to your water heater’s user guide for more information.

Are aluminum anode rods dangerous?

Aluminum in the Water Some plumbers say that aluminum anode rods are not safe because they put aluminum in your water supply. There are some clinical studies that suggest that aluminum might be a contributing factor in Alzheimer’s disease.

What happens when your anode rod goes bad?

A bad anode rod can cause discolored water, a rotten egg smell, air in the lines and intermittent hot water. The anode rod protects the tank of electric water heaters & signs it should be replaced are a rotten egg smell, no heat & strange sounds.

What kind of anode rods do you need for a water heater?

Zinc anode rods are essentially aluminum with a small amount of zinc. Although zinc rods do not usually come with a water heater, they can be easily installed. They are particularly a good option if you have sulfur smelling water coming from the tank.

Are all anode rods the same thread size?

The diameter of residential water heater anode rods is universal at 3/4 inches. Also to know is, Are all anode rods the same thread size? A: An anode rod is aluminum or magnesium cast around a steel core wire and hex head.

Can a water softener reduce the life of anode rod?

Water softeners reduce the life of anode rods. If your home has a water softener, the anode rod should be checked and replaced more often. Your water heater’s owner’s manual will have specific advice about anode rod inspection and replacement.

Which is more reactive magnesium or aluminum anode rods?

Because aluminum corrodes more slowly than magnesium, it may not be enough to combat corrosion in some water heaters. Your heater may slowly start to rust, despite having a functioning anode rod. Magnesium is more reactive and therefore their anode rods corrode faster.
