Here's the deal: anode rods usually last 5-10 years. If your water heater's been running for a decade or more, it's time to check it. You'll know it's time to replace it if you see white, chalky buildup on the rod or if the rod itself is less than half its original thickness. And if your hot water smells like rotten eggs? That's your anode rod screaming for help. Don't ignore it—rotten egg smells mean the rod's done its job and it's time to swap it out.
You don't need a fancy toolkit to check your anode rod. First, turn off the power to your water heater and shut off the cold water supply. Then, locate the anode rod—usually at the top of the tank, covered by a hex nut. Unscrew it (it might be tight) and pull it out. If it's coated in calcium or looks like a toothpick, replace it. If it's still thick and shiny, you're good for now.
If you're not comfortable with the basics, skip the DIY. Water heaters can be dangerous if you mess with the gas or electricity. We've seen too many Taunton homeowners try to replace it themselves and end up with a bigger mess. If you're unsure, call us—we'll check it in under an hour and replace the rod for less than a hundred bucks. It's way cheaper than replacing the whole tank.
Ignoring a bad anode rod is like ignoring a small crack in your car's tire. It might seem fine at first, but then—bam—you're stranded with a flat. Your water heater's tank can leak from the bottom if the anode rod fails, and that's when you're looking at a $1,000+ repair. A simple $50 anode rod replacement now saves you that headache later. We've helped dozens of Taunton homes avoid this exact problem. Your water heater's lifespan depends on this small part—so check it before it's too late.
