Phoenix water heatersThis Phoenix water heater is beyond repair! 

We get alot of calls for water heater repair in Phoenix, and the Phoenix Az metro area, and we always hate to have to explain to a customer that their water heater, like the one in this picture, is beyond repair.

Don’t let this happen to your water heater!  Water heater replacement is expensive!  By checking the anode rod regularly, and changing it when necessary, you can help prevent rusting of your water heater tank, and help avoid the expense of having to replace a water heater before it’s absolutely necessary.

If the anode rod, or galvanic cathotic anode, in your water heater is doing its job, it will corrode until there is little or nothing left of the rod, on a regular basis.  And, that’s a good thing!

While your water heater’s steel tank is protected with a glass lining, that lining will inevitably develop cracks and fissures that will allow the water (and the electrochemical components of the water) in the heater to come into contact with the water heater’s metal jacket – a situation that can quickly lead to corrosion and rusting of the tank, and then – well, goodbye water heater!

Your water heater’s anode rod can help prevent this. 

Because of this, every water heater comes with an anode rod, a metal rod which is normally attached to the top of the heater and projects down into the water in the tank.  Anode rods are made from magnesium, aluminum or aluminum/zinc alloy, and which type you use will depend on your local water conditions.  (Give us a call to find out which type is most appropriate for the water conditions in your part of Phoenix).

These metals are used in anode rods because they are all more “active” (meaning they react more strongly and more quickly to electrochemical elements in their environment, such as the minerals in hard water) than the metal in your water heater tank.

This hyper-activity results in the metal in the rod oxidizing more quickly than the metal in the tank; in other words, rust will accumulate on the surface of the rod and eventually consume the rod.  But, by attracting the potentially damaging elements in the water to themselves, these “sacrificial rods”, as they are often called, help discourage rusting and corrosion of your water heater tank, extending its useful life.

Regular water heater maintenance and repair includes the anode rod.

Because it’s such an important component of your water heater, it’s very important to have your anode rod replaced regularly.  If you have regular maintenance inspections of your home’s plumbing systems and fixtures, including your water heater (which we strongly encourage!) checking the anode rod as a part of that inspection is a must.

Changing the anode rod is an inexpensive water heater repair that will give you a good return on your investment in terms of how long your water heater will last, and how well it will function.  And, while changing an anode rod is fairly simple for an experienced plumber, unless you’re very handy, we don’t recommend most homeowners try it themselves.

Questions?  Give us a call! If you have questions about the anode rod in your water heater, or about water heater repair or water heater installation, in Phoenix or valley wide, give us a call.  An experienced Phoenix plumber is always available during business hours to answer your questions.
