Frequently Asked Questions and Answers
1. What is an anode?
An anode is simply a rod made of a special type of metal. It is
installed inside the tank so that it is immersed in the water. The
illustration shows a typical arrangement in a gas system.
2. Why is the anode there?
The anode's job is to attract corrosion to itself, to protect the
tank. It is a sacrificial item - this means it
is designed to be consumed in the course of doing its job.
3. How long does an anode last?
The original anode usually lasts about 4 years. Anode life
depends on a number of things, one being the quality of the water in
your area. The "hardness" of Perth's water has been increasing for
many years, and this can cause anodes to be consumed more quickly.

4. How often should the anode be checked?
For systems with one anode (that's most of them), we
recommend inspection 4 years after installation, then every 3 years
after that. Some systems have dual anodes - for these we
recommend inspection 8 years after installation, then every 6 years

systems we know about. We have seen most types of system, and
this list is being added to all the time.
6. How can I tell how old my hot water system is?
Most systems have their date of manufacture stamped
on them. It will usually be on a metal plate or a sticker, which may
be attached on the side or back, or may be on the inside of the
removable panel that covers the pilot-light and thermostat controls.
Below are pictures of some typical installations.
On this system, the information is on the inside of the panel
covering the controls. At right, you can see that the system was
manufactured in July 2002.

made in January 2001.
Another one with a sticker up near the top of the tank. System made
in December 2002.
7. My hot water system has limited space around
it. Can the anode be replaced?
Yes. Typically we need a little space above
the tank so that we can remove the old anode. Our replacement anodes
are a flexible type which can be fed into the tank in sections.
8. What will anode replacement cost for my
Our pricing structure is simple and is based on the
system's water capacity. Click here for
9. Can you remind me when my anode needs
Yes. We keep all customer details, and send out a
reminder letter when your next anode inspection is due.
