Anode Rod - General

A water softener that is not properly adjusted allows extra salt to flow through the pipes and / or into your water heater. The current sent by the powered anode will turn a part of the excess of salt into chlorine and a smell will occur. This will mean that your softener must be readjusted!

How is it possible?
Chlorine is produced by passing an electric current through a solution of brine (common salt dissolved in water). This process is called electrolysis.

To remove the anode rod from your water heater:

  1. Disconnect the powersupply.
  2. Locate the anode location according to your water heater model. It is usuallylocated ontop.
  3. Remove the insulating material if present and empty your tank.
  4. Remove the anode with a socket wrench and a power bar if necessary.
  5. Install your new anode and restart your waterheater.

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.

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. However, when you cut the anode, make sure that the bottom part does not fall into the bottom of the tank, as you will not be able to pull it out.

In confined spaces, cutting the anode rod technique is often used. Make sure to dispose the old anode rod in a safe way and as per your environmental waste regulations in your municipality.

If you don’t have enough space and you are tired of changing the anode rod, you should install a powered anode. Only 12 inches long, this anode is made to last over 20 years.

To loosen the anode rod of your water heater, it is important to wear a pair of gloves to protect yourself from heat, a socket wrench and a power bar for better support in confined spaces. Seek professional help if necessary.

To remove the anode from your water heater, it is important to wear gloves to protect yourself from heat, a socket wrench in the correct size and a power bar if necessary.Seek professional help if necessary.

The length of the anode rod is important in the case of a sacrificial anode. Indeed, as its name suggests, it sacrifices itself to protect your tank from corrosion. As a result, the more magnesium or aluminum there is on the anode, the longer the protection time of your water heater will be.

You can remove the bad smell in your hot water by removing the reacting magnesium anode rod that comes in contact with the magnesium in the water. However, this deprives your water heater of its only protection against rust. You can choose an aluminum anode rod that requires more maintenance or the titanium Corro-Protec impressed current anode that eliminates unpleasant odours and offers 20 years of protection against rust.

Yes, an anode rod is necessary. It protects your water heater from corrosion and extends its life. However, once the magnesium or aluminum from your anode is dissolved, the steel walls of your water heater will start to rust.

When the anode rod in your water heater no longer works due to wear and tear, it is important to replace your sacrificial anode with a new one. Indeed, this type of magnesium or aluminium anode protects the walls against rust by dissolving its alloy. Another solution is to purchase a Corro-Protec impressed current anode to double the life of your water heater against corrosion and water damage and eliminate unpleasant odours.

There are several names you can use when talking about an impressed current anode. Impressed current anode rod is simply a synonym for Powered Anode Rod, electronic anode or ICCP system.

It is important to change the sacrificial anode in your RV every year for a steel water heater. Aluminium tanks are generally not equipped with replaceable anodes because they have an inner coating of zinc and aluminium with the same protective function.

It is important to inspect the sacrificial anode every 1 to 3 years and replace it after more than 50% of its wear and tear to prevent corrosion of your tank. Its lifespan depends on the quality of your water. On average, the magnesium or aluminum anode must be changed every 3-5 years. For a powered titanium anode rod, it must be changed every 20 years.

You can buy a magnesium or aluminum sacrificial anode rod from a plumber, hardware store or on the Internet. There are also titanium impressed current anodes available on the Corro-Protec website that double the life of your water heater.

For your water heater, you have the choice between a sacrificial anode rod or an impressed current anode. As its name suggests, the magnesium or aluminum sacrificial anode dissolves over time to protect the surface of your water heater. The Corro-Protec impressed current anode forms a permanent protective layer on the tank walls.

To treat bad odours, it is recommended to use the Corro-Protec anode rod. This impressed current anode eliminates the bacteria responsible for the sulphur odour in less than 24 hours. In addition, the Corro-Protec doubles the life of your water heater, unlike a sacrificial anode.

It is preferable to choose a Corro-Protec impressed current anode in order to double the life of your water heater and eliminate unpleasant odours. For the sacrificial anode, it is recommended to use a magnesium anode, as aluminium residues that may be found in the water are harmful to health.

The size of your anode depends on your anode type and the capacity of your water heater. In the case of a sacrificial anode, its rod is much larger than an impressed current anode, because the more material there is, the longer it offers a protection time.For the Corro- Protec impressed current anode, its protection is provided by an electrical current that is proportional to the capacity in gallons of your water heater and not to the size of its rod.

If your hot water smells like oil, it is possible that the water supply or plumbing has been contaminated with gasoline, oil or bacteria. This can be a health risk. In rarer cases, you may notice an oil smell in a new water heater caused by a chemical reaction between the water and the tank components. This should disappear in a few weeks.

A rotten egg smell in your hot water can be caused by various factors. If you can only smell this smell on your kitchen faucet, it could be due to the fact that the drain is partially blocked by decomposing remains. The odour can also come from your water purifier if it is not regularly maintained. In most cases, a sulphur odour is caused by water with a high magnesium content that comes into contact with the original magnesium anode. The Corro-Protec anode is the ideal solution to this problem, because in addition to eliminating odours in a few hours, the anode stops the corrosion of your water heater and is guaranteed for 20 years.

If your water smell like sewage, your plumbing and supply may contain iron, algae, bacteria or decomposing organic matter. This problem may be due to the season of the year and may pose a health risk. During periods of limited use, water can become stagnant and develop these odour through stagnation and the presence of bacteria.

Each water heater is manufactured with a magnesium anode to temporarily limit rust. In most cases, the sulphur odour is caused by water with a high magnesium content that comes into contact with the original anode already present in the water heater. In addition, this smell can be created by a bacterium (sulfur bacteria). The Corro-Protec anode rod is the ideal solution to this problem, because in addition to eliminating odour in a few hours, the anode rod stops the corrosion of your water heater and is guaranteed for 20 years.

If your hot water smells like onions, it can be caused by different factors. Here is a list of the main factors:

  • A prolonged absence can dry out the pipes and lead to onion and sewer odour
  • A clogged drain
  • Incorrect temperature setting of the water heater that causes bacteria to grow
  • The metal in the water heater tank
