Skipped a year once on a rental with hard water—regretted it. The anode rod was basically gone, and the tank started showing rust stains not long after. Solar heaters do seem to chew through rods faster, probably from the higher temps. I get why people put it off, but in my experience, it’s not worth the risk. Replacing a tank is way more hassle than wrestling with a stuck rod.
Yeah, hard water really does a number on those rods. I’ve noticed the same thing—solar setups seem to burn through them quicker, probably because the water’s hotter for longer stretches. I’ve always wondered if using a powered anode would help slow down the wear, or if it’s just overkill for most folks. Have you ever tried flushing the tank more often instead of just swapping the rod? Curious if that actually makes a difference with mineral buildup, or if it’s just one of those things people say but doesn’t really help much.
I’ve wondered the same thing about flushing the tank. When I moved in, everyone kept telling me to do it every few months, but honestly, I skipped a year (oops) and didn’t notice a huge difference in performance. The rod was still pretty chewed up from the hard water, though. I guess it can’t hurt to flush more often, but I’m not convinced it’s a magic fix for mineral buildup either. Powered anodes sound interesting, but maybe a bit much unless you’re really battling corrosion.
Interesting point—I've also heard the advice about regular flushing, but I've always wondered how much of it is just habit versus actually necessary. Like you said,
Same here, honestly. My last place had pretty hard water, and I only flushed it once in two years. The performance didn't really dip, but when I finally got around to checking, the anode rod looked rough.“I skipped a year (oops) and didn’t notice a huge difference in performance.”
Has anyone actually had a tank fail early because they skipped maintenance for a year or two? Or is it just one of those “better safe than sorry” things that gets repeated? I’m also curious about those powered anodes—are they really worth the cost if you’re not seeing visible corrosion, or is it more of a peace-of-mind upgrade?
Skipped a year once when life got busy, and honestly, nothing exploded or leaked. But when I finally flushed the tank, the amount of gunk was... impressive. I figure it’s like changing oil in your car—maybe you can stretch it, but eventually you’ll pay for it. As for powered anodes, I’m tempted but haven’t pulled the trigger. Peace of mind sounds nice, but my wallet disagrees unless I see real rust or smell something funky.
