I've installed a few powered anode rods for clients, and honestly, results were pretty mixed. One homeowner swears it's kept their tank pristine for years, but another saw barely any difference and still ended up replacing the heater early. Personally, I'd stick to regular magnesium rods and just swap them out every few years—cheap, simple, and proven. Less hassle overall, especially if you're already juggling multiple properties or tight schedules...

Yeah, totally agree with you on this. I've seen similar mixed results with powered anode rods myself. Had one client who swore by it, but another still had rust issues within a year or two...go figure. Honestly, unless there's some specific reason (like super hard water or persistent odor problems), keeping it simple with magnesium rods and regular maintenance usually does the trick without unnecessary headaches.

Yeah, that's been my experience too. But have you noticed any difference between brands of magnesium rods? I've had a couple cheaper ones corrode way faster than expected...wonder if it's just bad luck or something else going on.
I've definitely noticed differences between brands too—you're not alone there. A few things I've picked up along the way:
- Cheaper rods often have impurities or inconsistent magnesium quality, causing them to corrode faster.
- Sometimes it's not just the rod itself but how it's stored or shipped. Moisture exposure before installation can speed up corrosion.
- I've had better luck with rods from plumbing supply stores rather than random online sellers. Slightly pricier, but they seem to last longer.
- Also, water chemistry can fluctuate seasonally or even due to local maintenance work, so corrosion rates might vary unexpectedly.
One thing I started doing is checking the rod every 6 months or so, at least visually. It helps catch issues early and gives me peace of mind. Plus, swapping out a rod is way cheaper (and eco-friendlier!) than replacing the whole heater prematurely.
Good points, especially about water chemistry. A few things I'd add from experience:
- Don't underestimate the power of local water hardness—I've seen rods eaten alive in months.
- Plumbing store rods are usually solid, but I've had decent luck online too...just gotta read reviews carefully.
- Checking every 6 months is smart, but honestly, who remembers? I set phone reminders now, otherwise it's "outta sight, outta mind."
