What is a Sacrificial Anode and why is it important?
The sacrificial anode is a critical component inside your hot water system that protects it from corrosion. This long rod is made from materials such as magnesium or aluminum. The role of the anode is to ‘sacrifice’ itself to prevent your hot water tank from rusting. What a hero! As the anode rod corrodes in place of the tank, the life of your water heater is prolonged.
Replacing the Anode.
As environmental effects play their part on the anode, its effectiveness diminishes over time. Once the anode rod is depleted, corrosion will look towards your hot water tank to settle into next. This can lead to leaks, reduced hot water efficiency, and eventually, premature failure of your hot water system. Replacement of the anode rod will extend the lifespan of your water heater significantly.
How long do Anodes last?
The frequency of anode replacement depends on several factors, including water quality, the material of the anode, and the size of your tank. As a general guideline, we recommend checking the anode every 2-5 years. This is where our plumbing health checks come in handy, every time we come out to your property we can run our eye over your hot water unit, and if its time to change your anode we will let you know. You can then make an informed decision on your hot water system maintenance.
