Question about Rheem Water Heater Anode Rod AP12938

Where is anode rod located on 100 Gallon rheem water heater natural gas

Posted by on

1 Answer

Anode rods for tank-type water heaters are located on top of tank.
This is true since anodes are about 44" long.
Top of anode is standard 1-1/16" hex nut.
Anodes can be located in 2 different places: either directly screwed into top of tank -or- attached to hot water nipple.
Most times the exploded parts diagram in manual simply shows 'anode rod' without specifing exact location. If your tank has long warranty, then it can have two anode rods, and 1 will be on top and the other probably attached to hot water nipple, or there could be two anodes screwed into top of tank.
http://waterheatertimer.org/Replace-anode-rod.html

If anode is screwed into top of tank, then it will be under a plastic cap -or- it will be concealed under the top cover of tank.
Look for plastic cap, and if none shows, then remove screws holding down metal cover and look there for 1-1/16" hex nut.
Lastly, remove hot water nipple and check for anode located there.
If you have 2 anode rods, then replace with same metal for each.

I have water in the junction box on top of my hot water heater and into the electrical conduit leading to the hot water heater.


I do not see your earlier post with photo.

The problem could be the conduit.....
-disconnect the conduit and wires from water heater
-run wire into a junction box set lower than top of water heater... -then run another #10 wire from the junction box up to water heater...
-So if water is coming from conduit, it will accumulate into junction box and not in the water heater wiring cavity.

Next thing....
... a water softener can cause rusted tank.
-Softened water adversely affects anode rod...
-causing anode rod to deplete faster...
-once anode rod is gone, then tank begins to rust.
-Here are details for checking anode rod each 2-3 years:

Energy factor rating


Rheem 50 gallon Pro52-2 has EF .95, which makes it ordinary 240Volt 4500 watt non-simultaneous electric water heater that produces about 21 gallons hot water per hour, with 67 gallon first hour delivery.
Recommend 80 gallon per hour first hour for oversized bathtub.

Anode rod is located on top in separate port.
Anode keeps tank from rusting.

Year of Rheem water heater manufacture shows 3rd and 4th digit of serial number.

Can't locate the year of manufacture of my Rheem Fury Model 29-40S-2


Generally the year of manufacture for Rheem is 3rd and 4th digit of serial number. 06 is 2006, 92 is 1992 etc.
Older gas water heaters are better than new ones, and easier to keep repaired and maintained.
http://waterheatertimer.org/How-to-maintain-water-heater.html
Regardless of age, the key factor is whether tank is rusted, or rusting.
Open drain valve and check if water is rusted.

Where is anode located mdel no. 82yp30-1


Question posted under Rheem water heater.
Model number does not describe water heater.
Model number posted in question does not appear at Rheem, and does not appear in a web search for water heaters.
Here are options:

1) Add a comment and describe water heater in detail so expert can access more information

2) Contact Rheem.
http://www.rheem.com/Contact.aspx

3) If this is tank-type water heater, the anode is located on top of heater.
Look for 1-1/6" hex nut located under a plastic plug.
Some anode rods are connected to the hot-water nipple.
Sometimes the top cover has to be removed to find anode hex nut.
I have used impact wrench on anode, and could not remove in some cases.

Odor in hot water


Change anode rod.
Typically, odors are caused by bacteria reacting with anode rod, and odor is eliminated by replacing anode rod.

I have a 40 gallon rheem water heater for a mobil home that is leaking from the top.


If water heater is leaking, then open following 2 links to avoid tank rupture and troubleshoot leak:
http://waterheatertimer.org/Emergency-steps-for-leaking-water-heater.html
http://waterheatertimer.org/Water-heater-is-leaking.html

Open following link if you want to install your own gas water heater:
http://waterheatertimer.org/How-to-install-gas-water-heater.html

40 gallon electric heater at Lowes costs 207, and is easy do-it-yourself using same basic information shown in link above for installing gas heater, except less work.

To have gas water heater installed, can run $2-300 for installation plus cost of heater.
40 gallon natural gas water heater at Lowes starts at $300+, and tanks with longer warranty cost more and last longer.
Trailers require specific type of gas water heater, so be sure to request correct model.

If you maintain the tank: keep chemicals out of same room as gas water heater, attach bare copper ground wire between hot and cold pipes, flush tank each 6 months, clean gas burner each year as shown in manual, read the manual entirely for specific information about your model, and inspect/replace anode rod every 2-3 years then basic 6-year tank can last much longer.

Where is the anode rod located on the rheem 81VP20s


Anodes are located on top of water heater.
There are no hard fast rules for location, either by model number or brand.
Most times the manual is likewise vague.
1) There is hex head visible on top of tank.
2) Hex head is located under a plastic cover
3) Hex head is located under metal top, so remove screws holding top, and lift top off to view hex head
4) Anode is connected to hot water nipple.
5) With 9-12-15-and lifetime tanks, you can have 2 anode rods, and each has to be made of same material to work properly. Usually magnesium-aluminum instead of aluminum.
But if you inspect and change anodes frequently to prolong life of tank, then one is as good as the next.
http://waterheatertimer.org/Replace-anode-rod.html

Open following links shows Rheem anode rods
http://waterheatertimer.org/pdf/Rheem-Ruud-anode-rods.pdf
http://waterheatertimer.org/pdf/Rheem-Ruud-water-heater-parts-guide.pdf
Tech resistor anode rod has resistor added to prolong life of anode.
You can cut rod off to fit size of tank. You want anode 5-6" from tank bottom so sediment build-up doesn't reach anode.
Anodes are standard 1-1/16" hex head.

Tank is rusted out, and requires replacement.

I) To protect yourself from ruptured tank, you should turn it off and use it only when hot water is needed.

II) How to install ordinary tank-type water heater yourself:
http://waterheatertimer.org/How-to-install-gas-water-heater.html

III) There are 5 preventable things that kill a water heater and cause it to rust away.

1) Anode rod depletion.
Loosen anode rod before installing water heater.
http://waterheatertimer.org/Replace-anode-rod.html

2) Stray current corrosion
http://waterheatertimer.org/9-ways to save-with-water-heater.html#Ground-tank

3) Sediment build up because no water softener
http://waterheatertimer.org/Clean-sediment-out-of-water-heater.html

4) Corrosive effects of water softener, and anode rod not inspected (see #1 above)

5) Chemicals stored in same room as gas appliance.
