I was not very educated about powered anode rods until I researched why water heater tanks rust. I have replaced 2 water tanks in the past 5 years. I have a rubber drip pan on the bottom so it is not sucking moisture from the cement garage floor. Our hot water odor was terrible. 2 years ago I purchased a popular powered anode on amazon. 8 days later my hot water turned black in my mud room when I turned on the faucet for about 1 minute then turned clear. I pulled their product out and the metal rod was pitted with brown and black and silver on the metal rod, junk. I purchased this product 5 months ago, no discolored water, no odor so I pulled the rod out of my heater figuring it was doing nothing. The rod was as black as new, plugged the power supply back in and it turned red then green so I know it is working properly as described. Very happy and this is my review.
