Where is Anode Rod on Rheem Water Heater?

The anode rod in your Rheem water heater is located on top of your tank. More precisely, your magnesium or aluminum sacrificial anode is visible through a hexagonal head located in the center of your tank under a plastic cover. Refer to your water heater’s user guide for more information.

    Hi there, we have an 8 gallon Rheem, and can’t see from the manual where the anode is. Any direction for model #XE10P06PU15C0?

      Looks like you need to remove the top of the tank to access the anode rod. It’s located on the right. Please see page #7 of this document : Owner Manual

    I have Rheem model XE50M06ST45U1. I have two plastic covers, which one i have to use?

      The anode rod on this Rheem water heater is located right under the cold water inlet.

    replaced anode rod on my rheem 50 gal tank but still smells. can you tell me if I the tank has 2 anode rods the model number is XG50T09HE40U0

    • Corro-Protec on October 10, 2020 at 4:06 pm

      According to the owner manual, this model only have one anode. Even if your tank had two anodes, we suggest replacing only one with our powered anode rod and let the second magnesium anode in place.

    I have a Rheem model number XE20P06PU20U0 water heater and the top is completely smooth metal. Where is the anode rod in this model–and do I need to remove the metal top to locate the access for the anode rod? Thanks! Tony

      Hello Tony, thanks for that question. Yes, you will need to remove the metal top in order to access the anode.

    I have a newer rheum electric water heater and looks like there is insulation above, do I remove to get to the anode rod. The water heater is 50 gallons.

      Hello Brian,
      Yes, it’s possible that you need to remove some insulation on the top of the tank in order to change the anode.

    I can’t seem to find the Anode rod or hex nut on top of my Rheem water heater, model # XE40M06ST45U0.
    Is it really under one of the rubber caps and beneath the insulation?

    • Corro-Protec on August 24, 2020 at 1:47 pm

      Yes, the anode rod on this Rheem water heater is located under the plastic cap just in front of the cold water inlet.

      I found mine in the tank under the supply line to the house. It was not under any clear plug as they say. I probed 8 inches into the insulation at all three plugs and found nothing. Should have found it under the insulation about 2 inches at most. It was a special order rod. Home Depot does not stock this type of rod.

    I have a 40 gal electric rheem water heater took both plastic plugs out no rod where else could it be

    • Corro-Protec on July 27, 2020 at 11:46 am

      Hello Jim,

      It should be under one of those plastic cap. Sometime, you will see some insulation on the top of the anode.

    I’m looking for the anode rod location on my Rheem Model 21VP50E. I took two plastic covers off and removed (dug out) the insulation I was looking for and did not see the hex head I was expecting.

    • Corro-Protec on July 2, 2020 at 7:52 am

      Hello Scott,

      Do you have any other plastic cap on the top? The anode should be under!


  9. Karen Winchester on January 22, 2020 at 4:39 pm

    I have a Rheem 30 gal electric water heater… 12 years old. Would like to change the anode, but no hex nut on top. There are 2 plastic covers (with insulation under them ??). Is the hex nut under that?? Model # 82SV30-2

    • Corro-Protec on January 22, 2020 at 9:01 pm

      Hello Karen,

      Yes, the anode rod in your Rheem water heater should be located under the plastic cover.

      Have Rheem water heater Model E40 2 RHMH in mfrd home, with pressure tank on top of heater. Don’t find rod on side. What do I do?

  10. Ray Hammons on November 19, 2019 at 6:27 pm

    I have 2 hexagonal heads on my heater. One on each side of pressure valve. How do know which one it is or do I have 2? Also one is packed with fiber insulation and one is foam. Pls help.

    • Corro-Protec on November 20, 2019 at 9:10 am

      Hello Ray,

      To know where is the Anode rod on your Rheem water heater, I would like to know the model number of the tank.

      Thank you,

      • Ralph Crawford on November 26, 2019 at 5:36 pm

        I have the same question. My unit is a model 82v52-2. Also the dip tube part #SP13763M for it seems to be made of unobtainium. No one has one. Thank you.
