What size anode rod do I need?

What size anode rod do I need? 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.

Are anode rods standard size? Some anode rods are 33 inches in length, while others are 44 inches in length. You may need to cut it down to fit your water heater if you have a smaller unit (often referred to as a ‘low boy’ or ‘stubby’) that is only 30 or 40 gallons.

Are anode rods universal? In most cases, water heater anode rods are universal. The only exceptions are : Buderus : They use another type of threading to install the magnesium anode. Bradford White : Some model have the anode is built into the hot water outlet.

What size nut is a anode rod? 3 Locate the anode rod on the water heater; if necessary, unscrew and lift off the cover from the top of the heater. 4 Use a ratchet wrench and 1 1/16-inch deep socket to unscrew the anode rod from the heater.

What size anode rod do I need? – Related Questions

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.

Is it OK to remove anode rod?

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

How do I know if my anode rod is 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.

Are powered anode rods worth it?

As mentioned, powered anode rods are well worth the cost, but may not be ideal in every situation. Additionally, you may not wish to replace a rod which is still good just to gain the benefits of a powered one.

How much does it cost to replace 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.

Can a bad anode rod causing rotten egg smell?

Many anode rods are made of magnesium or aluminum. When these rods corrode, the metals react with the sulfates in the water, turning the sulfate into stinky hydrogen sulfide.

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.

What is the best type of anode rod?

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.

Should you use Teflon tape on anode rod?

Yes, teflon tape may reduce the effectiveness of the anode rode by electrically insulating the rod from the water heater chassis. The chances of it completely isolating it are nearly impossible though. Use pipe joint compound if you have it, and use teflon tape if you don’t.

How often should you replace an anode rod?

Most water heater manufacturers will recommend inspecting the condition of the sacrificial anode every one (1) to three (3) years and replacing it when it has been consumed more than 50%. This is especially true if you have hard water or use a water softener.

Should I replace anode rod?

When the rod itself becomes so corroded that it can no longer do its job, the tank soon rusts out, leaks and needs replacement. However, if you replace your water heater anode rod before it fails, about every five years, you can double the life of your water heater.

How do I choose the right anode rod?

the rod should pull straight out. If your water heater doesn’t have a separate hole for your anode rod, it is most likely attached to the hot water outlet. Unscrew the flex supply to the hot water outlet, which should enable you to unscrew the anode rod and pull it out to check.

Do I need an anode rod if I have a water softener?

If you have a water softener system, you should have the anode rod of your water heater inspected and replaced more frequently. This is a fairly simple process – and certainly much cheaper than replacing the entire water heater unit.

Can a water heater work without an anode rod?

Without a working anode rod, your water heater tank will be vulnerable to rust, corrosion, and other damaging effects of chemicals and minerals in your water supply.

Do aluminum anode rods smell?

The bacteria reacts with the anode rod in your water heater to produce the smell. Aluminum and magnesium anode rods are the types that bring the smell. Smelly water is most common in buildings connected to a well system. Water softeners can also increase the problem of smelly water significantly.

Do all hot water tanks have anode rod?

Anode rods are an essential component of tank-style water heaters. Most anode rods are sacrificial, meaning they are designed to corrode (instead of your water heater lining). Tankless water heaters don’t have anode rods, but all standard tank-style water heaters do.

Why does my hot water stink?

You are most likely on well water, and there is a bacteria, known as SRB (sulfate-reducing bacteria), that gets into water heaters and, although harmless to humans from a pure health perspective, creates the odor by digesting naturally occurring sulfur-based elements in the water, releasing tiny amounts of hydrogen

How long will a powered anode rod last?

DESIGNED AND TESTED TO LAST MORE THAN 20 YEARS

When a hot water tank is exposed to corrosive water, the magnesium anode will transfer electrons to the inner side of the hot water tank to protect it. The anode will slowly break up. After a few years, there will be no more protection for corrosion.

Can I replace anode rod myself?

Water heater anode replacement can be completed by homeowners. If you’d like to inspect or replace your water heater’s anode, follow these steps: For electric water heaters: Turn off the water heater and cut power to the unit from the circuit breaker.

How often should you flush hot water tank?

It is recommended that you flush your water heater at least once per year. Doing so will help to prevent the potential problems that sediment can bring over time.

How do you remove hydrogen sulfide from water?

Hydrogen sulfide may be reduced or removed by shock chlorination, water heater modification, activated carbon filtration, oxidizing filtration or oxidizing chemical injection. Often treatment for hydrogen sulfide is the same as for iron and manganese, allowing the removal of all three contaminants in one process.
