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.

    Just purchased for my 90 Gallon Rheem # MR85245

    Where is the anode rod located on this model. Have hot water outlet/ Cold water inlet/ and center location w/ ‘pop off’ safety valve.

    Model 81V-66D my water heater has 4 plastic caps on top.. I still have the manual and it shows the anode rod to be on the back side.. your video shows removing the one in the center.. can you tell me which is correct or does it have two?

      All water heaters are designed differently. You need to follow your water heater owner’s manual in order to find the magnesium rod.

    I have a XE60T06ST45C0 Rheem hot water tank. The relief valve is in the exact dead center of the tank, with 2 clear plastic plugs. One is close to the relief valve and the other is near the outer edge of the top.
    When I take off the plug near the center, I can poke a screw driver down about 1”.
    Before I go digging around, is this where the anode is?

    • Corro-Protec on October 21, 2021 at 4:02 pm

      Dave, yes this should be where the anode rod is located.

  6. Leo Chu on August 18, 2021 at 5:21 pm

    My unit model no: 22V50F1. Need your help to find the location of anode rod. Thank you!

    • Corro-Protec on August 23, 2021 at 7:39 am

      The anode rod on the Rheem 22V50F1 is located right behind the flue. There might be a white plastic cap on top of the rod with some insulation.

    We have a Rheem water heater proe50 m2 rh95. Very stinky hot water and wanted to replace the anode. This unit was installed 2/2020. We took both clear caps off and all we found is Styrofoam. Do we need to remove the whole lid like some answers say, or do we just dig out styrafoam?

    • Corro-Protec on August 2, 2021 at 2:00 pm

      You need to remove some insulation on top of the anode in order to be able to replace it with the Corro-Protec anode rod on your Rheem water heater

    • James Lee on August 22, 2021 at 5:59 pm

      It’s under the larger cap. mine was about 4 inches deep. dig it out and you will see the hex nut.

  8. Jackie S. on July 16, 2021 at 10:25 am

    I have an 80 gal heater, do I have to replace the rod if it is removed?

    • Corro-Protec on July 21, 2021 at 7:55 am

      yes, otherwise your water heater don’t have any protection against corrosion

  9. Gene on April 29, 2021 at 4:28 pm

    Can you tell me if the Rheem 20 gallon / 2000 watt, 120 volt – Mod.#XE20P06PU20U0 hot water heater has a replaceable rod for it?

    • Corro-Protec on May 5, 2021 at 7:03 am

      Yes, anode rod in this Rheem is located on the top below a plastic cap.

  10. Jodie on March 7, 2021 at 7:28 am

    I want to change the anode rod on my rheem professional model XE50T06ST45U1 and I have removed the plastic cap. Dug out some insulation down to my middle knuckle and no hex nut. Where is it?

    • Corro-Protec on March 8, 2021 at 9:42 am

      According to the owner manual, the anode rod on a Rheem XE50T06ST45U1 is located right in front of the cold water inlet under the white plastic cap

  11. Debra Andrews on December 27, 2020 at 10:30 am

    my father has a 1 year old Rheem hot water tank , Rheem Pro E50 T2RH95, looking to replace the anode rod to purchase your powered rod but don’t know where it is, have no manual. Please advise if you can.

    • Corro-Protec on December 28, 2020 at 9:03 am

      On this Rheem water heater model, the anode rod is located right in front of the cold water inlet.

  12. Randy on November 22, 2020 at 4:36 pm

    Does xe50t06st45u1 have 2 anode rods?

  13. Kris on November 14, 2020 at 12:46 pm

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


    • Corro-Protec on November 16, 2020 at 10:25 am

      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

  14. Dmytro on October 27, 2020 at 11:08 am

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

    • Corro-Protec on October 27, 2020 at 4:01 pm

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

  15. dalton starkey on October 9, 2020 at 3:01 pm

    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.

  16. Tony Panian on September 24, 2020 at 12:31 pm

    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

    • Corro-Protec on September 24, 2020 at 1:13 pm

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

  17. Brian on September 4, 2020 at 10:52 am

    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.

    • Corro-Protec on September 8, 2020 at 11:48 am

      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.

  18. Danny on August 24, 2020 at 12:39 pm

    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.

    • Paul Kovach on September 20, 2020 at 12:36 pm

      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.

  19. jim on July 18, 2020 at 2:11 pm

    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.

  20. Scott Current on June 28, 2020 at 3:45 pm

    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!


  21. 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.


    • Paul M Muehlberg on June 25, 2021 at 3:48 pm

      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?

  22. 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.
