Signs That Indicate It’s Time for Anode Rod Replacement

Located inside your water heater tank, the anode rod plays a crucial role in preventing corrosion and extending the lifespan of your unit. Over time, this sacrificial component can deteriorate, leaving your water heater vulnerable to rust and other issues. For residents in Bakersfield, CA where water quality and temperature fluctuations can affect water heaters, being proactive about maintenance is key.

Here are some signs that indicate your anode rod may need replacing.

1. Visible Corrosion

When the anode rod is heavily corroded or “chewed up” during a routine water heater services, it’s a clear sign that the rod needs to be replaced. A healthy anode rod will have some wear, but if you can see six inches of the steel core wire, it’s time to call in The Plumbing Doc for a replacement.

2. Rotten Egg Smell

A sulfuric, rotten egg smell emanating from your hot water can indicates that the anode rod is failing to prevent corrosion, leading to a reaction that produces hydrogen sulfide gas. Don’t ignore this unpleasant smell; it’s a sign for a new anode rod and to consider water heater repair in Bakersfield, CA.

3. Rusty Water

If the water from your heater has a reddish-brown tint, it’s likely due to a deteriorating anode rod. Rust-colored water suggests that the rod is no longer effectively preventing corrosion inside the tank. This discoloration is a signal for at least an anode rod change, or a water heater replacement at most.

4. Pinging Sounds

Strange noises coming from your water heater, such as pinging or knocking sounds, can indicate that the anode rod is breaking down. These sounds are caused by pieces of the rod falling off and hitting the inside of the tank. Call your water heater installation company for a new anode rod.

5. Metallic Taste in Water

Taste can affect the quality of your drinking water and can be a cue for immediate anode rod replacement.

If you prefer not having to worry about an anode rod and when to replace it, a tankless water heater might be a better option as tankless units don’t require anode rods.
