Now These Are Anodes!

Hot Water Storage Tank - New Anodes

Yesterday we looked at anodes in need of replacement.  Today I am highlighting new anodes, both thread-in and weld-in.

Sacrificial magnesium anodes serve one roll in a Domestic Hot Water Storage Tank application.  Anodes sacrifice themselves to protect the unlined areas of the tank, the inlets and outlets.  Corroded inlets and outlets are the number 1 reason for premature tank failure.  Regular anode replacement is imperative!

Do Your Anodes Look Like This?

Hot Water Storage Tank - Depleted Anodes

In my last blog, I explained the importance of regular replacement for sacrificial magnesium anodes and the roll they play in Domestic Hot Water Storage Tanks.  Today, I want give you a handful of examples in which anodes have passed their servicing life.  These anodes have now compromised the unlined areas of the tank that they are meant to protect, the inlets and outlets.

Number 1 Reason for Premature Tank Failure.

Hot Water Storage Tanks - Sacrificial Magnesium Anode

Q. What is the number 1 reason for premature tank failure?
A. Lack of anode replacement or installation.

Let's begin with the definintaion of an 'Anode' from Wikipedia, the free encyclopedia.

Anode - "A galvanic anode is the main component of a galvanic cathodic protection (CP) system used to protect buried or submerged metal structures from corrosion.

They are made from a metal alloy with a more "active" voltage (more negative electrochemical potential) than the metal of the structure. The difference in potential between the two metals means that the galvanic anode corrodes, so that the anode material is consumed in preference to the structure.

The loss (or sacrifice) of the anode material gives rise to the alternative name of sacrificial anode."
~ From Wikipedia, the free encyclopedia.

In a Domestic Hot Water Storage Tank application, magnesium anodes sacrifice themselves to protect the unlined areas of your tank, the inlets and outlets.  However, most people are simply not aware that they require replacement.  This has lead to more unexpected tank failures and leaks than any other cause.  Anodes in a DHWST require replacement every 1-3 years depending on the quality of water.

Below are examples of depleted and new anodes for both weld-in and thread-in anodes.
