Product Overview

Anode rods are the most important line of defense in preventing corrosion and leaks in your water heater. These devices work because the metal in the rod is sacrificed so the tank does not corrode. As the anode works, the life of the water heater is increased. The anode should be checked and replaced every couple of years. This 4 section Rheem PROTECH anode is 3/4 in. NPT X 54 in.
  • Fits many brands of water heaters (sold separately)
  • Helps prolong the life of your water heater (sold separately)
  • Patented resistored technology help increase the life of the tank and elements
  • Magnesium construction
  • 3/4 in. NPT fitting

Exactly correct replacement Anode Rod for my Rheem water heater. The flexibility of the segments ...
Exactly correct replacement Anode Rod for my Rheem water heater. The flexibility of the segments allowed for installation as my water heater is under the staircase to the basement. It was "folded up" for shipment so a little careful straightening of the joints with pliers was necessary so it would hang vertical in the tank. The fastener is a 1-1/6" hex head, and takes a LOT of torque to get the OEM part loose. Leave as much water in the tank as possible for stabilizing weight. I was twisting my 80-gallon tank with about 78 gallons in it, without breaking free the OEM rod. With some creative rachet-straps to hold the tank in place and I stepped up to a 3/4" square-drive socket (with a cheater pipe on the handle), it finally broke free. One of the new high-torque impact drivers may be the way to go! I added 6 wraps of teflon tape to the new Anode's threads for easier replacement next time.

Easy Replacement - Don't Wait Too Long!
Our new home came with a Rheem 50 gal water heater. It failed at 4 years, which seemed unusual. Rheem took care of us, so no complaints there! Being a long-time forensics expert, I just had to take that water heater apart to see what happened. The anode "rod" was gone but for a few pieces of thin wire. Not good. The new heater, like most, recommends checking the anode rod every year and replacing it if 6" or more of the rod has dissolved from either end of the anode - good advice. On the two year anniversary of the new heater installation, I pulled out this anode. Definitely time for replacement. Replaced with this magnesium unit which made installation a breeze. Using my new Makita brushless impact wrench made removal a one minute job. The photo shows the two year old rod alongside a segment of the new rod (the new rod was long, as is often the case). Check the anode on a regular schedule, use the right tools, and you will not only extend the life of the water heater, but will find it a painless process.

    When you pay $200 more for a higher end water heater, it usually just comes with 1 more anode rod. If you change yours out after a few years, it's basically the same thing; you'll add a few more years to its life. The hard part is changing it out. professionals use a huge impact driver, not the typical impact one you use to screw in deck screws. I had to use a long cheater bar and an impact and it still took me 30 minutes to get it out. Remember to drain your tank, shut off the pilot, water, etc and good luck.

    Good anode!
    Worked as advertised. The hardest part was getting the old anode out of the water heater.

    I don't know how to rate something I didn't have the opportunity to use. I could not remove the old anode rod. I tried using a pneumatic impact wrench and a breaker bar with a 4 feet extension. The hex head nut was so thin that I was only able to round it off with the socket. Rheem: consider a thicker hex head capable of withstanding the large torque required to remove an anode rod after a couple of years in service.

      This is the anode rod to get if you have limited clearance - Good Price and made for Rheem Water Heaters (Mine: PRO+G75-75U RH). I did have to use an electric impact wrench to get the old rod out, and I also had to trim the new rod length with a hack saw. If in California, don't forget that you may also need an expansion tank for your water heater - the excess pressure from the WH is blocked from going back to the street by environmental 1-way valves - so your system needs to deal with it.

          I would recommend this product because there are four rods connected to a cable. This way it's easier to insert it in the water tank. I cannot rate this a five star because I don't know how long it's going to last.

          Worked as intended. Getting out the old rod was the difficult part. Had to heat up the plastic around the bolt to get the socket to fit and get it out.

          Good Idea BUT Needs Improvement
          The "Rheem Protech" Anode rod seemed like a smart, proactive replacement for the anode rod in my new Rheem XG50T12HN38U1 (50 gallon, tall, natural gas, ultra-low NOx) water heater, to facilitate future maintenance, given there's only 19" of headroom between the top of the water heater and my garage ceiling. However, the 12" long magnesium rod sections are separated by about 3" each and so the overall length is 54" (4 x 12 + 6). The factory-fitted anode rod in the Rheem XG50T12HN38U1 has an overall length of 44". Therefore, you'd need to chop 10" off the last magnesium rod of the "Rheem Protech" product to arrive at the required length. Not only is that a waste of good magnesium rod, but given the 3" gaps between them, there's actually less anode surface area than with the standard 44" non-segmented rod. Ideally, this product should be made available in several different lengths that match the actual lengths required by different models of Rheem water heaters.

            Worked great, easy to install with limited head room. Impact wrench really makes this job easy to do. It would be a struggle to loosen old anode with a breaker bar and trying to prevent the hot water tank from spinning.

            Magnesium Anode Rod was shipped fast and received at Home Depot Store as advertised. Magnesium Rod received was exactly like picture and went into Hot Water Tank with no problems. We will see if this works better than the aluminum rod that was in tank when I purchased it. The previous rod had a jelly like substance on it which I read could be related to high chlorine reacting with aluminum rod. So hopefully the magnesium rod works better. So happy with product and was priced affordably.

            Copper cable connecting each segment is too stiff, preventing the rod from hanging straight down when installed. Otherwise it would get5 stars.

            **NOT** Resistored
            At least mine wasn’t. A genuine Rheem part in their box, correct part #. Original: about 61 ohms between the threads of the head and anywhere on the rod (including the core wire). This replacement: near-zero ohms (residual of my DMM test leads) from the threads to anywhere on the brand-new anode sections or the copper braid connecting wire links. Reached out to Rheem and got a foot-shuffle non-answer. Hopefully someone at HD will see this, get with Rheem, and get back to me with a non-bullpuck explanation. Screams of false advertising to me. For a NON-resistance segmented sacrificial anode, seems fine so far.

              I'm sure the anode would have worked perfectly, unfortunately I couldn't get the old anode out of the heater. I tried a 4 foot cheater bar and a impact driver at 125psi, no luck. Before you buy, see if you can loosen the anode before you buy.

              Extremely difficult to replace. Used strap around water htr & braced buckle against corner of closet using some plywood after draining a few gallons of h2o out. Had to remove both nipples and exhaust vent to place 1-1/16 socket with 3/4 in breaker bar and cheater extending 3+ feet out, still took all of my strength. Old anode was encrusted with mineral deposits even though our water isn’t “hard” in Boulder Colorado. New one with short segments was easy to install. Used pipe thread sealant to ensure no leaks. I hope my tank will last 10-20 more years after doing this maintenance.

              This rod arrived to my store on time and not a bad price and good quality. After hachsawing 3 inch off of it so it won't touch the bottom of the tank, droped it in 50 gallon ge water heater that is made by rheem. I had to remove the top element so it would be standing straight so i can screw in the 1 1/16 hex nut otherwise would be impossible to tie it down because it is crooked.

                Easy to install and was a direct replacement for a 10-year-old anode rod in my water heater. Given the small clearance above the water heater, it was easy to install because of its flexibility. Rheem confirmed that it would work in my water heater.

                Perfect fit. Best part is that it's flexible and i only had 30 inch of clearance. So I had to cut the previous 44 inch rod and replace this one. Now I do t have to ever worry about cutting it in future.
