What size is the anode rod nut?

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 kind of anode is a sacrificial anode?

Sacrificial Anodes One type of cathodic protection system is the sacrificial anode. The anode is made from a metal alloy with a more “active” voltage (more negative electrochemical potential) than the metal of the structure it is protecting (the cathode).

Why are sacrificial anodes important to a hot water tank?

Conversely, when hot water system anodes have not been correctly maintained it can cause the makeup of a water storage tank to be compromised causing it to leak, and the water to fill with rust residue. Sacrificial galvanic anodes are the most functional part of hot water systems because they keep the interior of the tanks rust-free.

When to replace an anode in a hot water system?

Replacing the anode before it has completely deteriorated is essential as once the anode is gone, your hot water system will rust out and you’ll have to buy a new system. To check the condition of the sacrificial anode in your hot water system, first, refer to the owner’s manual to find out if the rod is easily accessible.

What kind of anode is needed for cathodic protection?

The anode must have high anode efficiency (i.e., the current produced by the metal dissolution must be readily available for cathodic protection).

Where can I get an anode replaced in my hot water system?

Call Moyle Plumbing on 07 3807 7327 for hassle-free sacrificial anode replacement. Replacing the sacrificial anode is the easiest and most cost-effective way to extend the life of your hot water system.

Do you need a sacrificial anode for a salt water pool?

It’s difficult to say whether a sacrificial anode is absolutely necessary for every salt water pool owner. There are a lot of variables that include the overall water chemistry and the types of metals in your pool system. In the realm of pool chemistry it’s often difficult to give a blanket answer because of the many variables.
