Why The Anode Rod Matters in a Water Heater

Traditional water heaters usually last for up to 10 years or more. However, they can only do so with proper maintenance, which includes changing the anode rod regularly. This component plays a crucial role in keeping your unit efficient and preventing costly water heater repair in Northridge, CA. Read on as Roberts Plumbing Hydro Jet & Rooter dives deeper into its importance.

WHAT IT IS

Anode rods are long metal rods made of steel wire coated with aluminum or magnesium. This sacrificial rod is inserted into the tank during water heater installation, and it degrades over time. 


The anode rod protects your water heater by drawing corrosive elements first before they hit the tank, but once it’s completely rusted, it will no longer serve its purpose. That said, work with a professional plumber in Northridge, CA, from Roberts Plumbing Hydro Jet & Rooter to help you inspect your anode rod and replace it when necessary.

WHY IT MATTERS

Without an anode rod, it won’t take long for your water heater tank to fail. The rust will penetrate the lining of the tank, weakening it and eventually resulting in leaks. When left neglected for too long, you might end up dealing with not only premature hot water heater replacement but also costly home damage and mold growth.


An anode rod typically lasts for around three to five years. However, it still pays to check it every time you enlist water heater services to ensure it remains in good working condition. This simple preventative measure will give you peace of mind knowing that your water heater won’t cause any trouble or inconvenience at your home.
