Air in system. Make sure there is no sources of ignition and loosen the supply line at the heater and purge all air. Mske sure your source valve is open. then turn off yje heater after tightening the line. Let sit in off position for 15 minutes. Then turn therm knob to on slowly and then over to pilot, depress pilot button and hold a ffew seconds. Pilot should light. If so, hold for a few and then release and turn ti on position. Good Luck.

SOURCE: Believe I need to buy

If thermocouple is from ordinary tank-type water heater, then it is a generic part with different lengths 15" 17" 21" 24" 30" available at hardware of home center.
I suggest reading manual for installation information, advisories, and required maintenance.
http://waterheatertimer.org/pdf/Rheem-Ruud-water-heater-parts-guide.pdf
http://waterheatertimer.org/How-to-install-gas-water-heater.html#clean

There are good utube videos on replacing thermocouple.
Tip of thermocouple has to be positioned in the pilot flame.
The heat on tip of thermocouple causes millivolts of electric current that travel back to the gas control valve and the electrical signal causes gas control valve to keep gas flowing down the pilot tube to the pilot light.
If pilot light blows out or if pilot tube is clogged and needs to be cleaned, or if gas valve has gone bad, then tip of thermocouple cools down and electric signal back to gas control valve causes gas control valve to shut off gas going to pilot.

When attaching thermocouple to gas control valve, it is finger tightened.
Be careful and do not cross-thread thermocouple. Just use your fingers to start the nut.
Finger-tighten thermocouple and then add 1/4 turn using small wrench.
The end of thermocouple has a small piece of insulation that isolates the electric current from body of gas control valve. If thermocouple is overtightened, the insulation is crushed, and electrical current millivolts short out and no signal reaches gas control valve, so gas control valve keeps gas turned off to pilot tube.

If this is a tankless water heater, then open following link with troubleshooting resources and contact information for Rheem.

How to how to install the anode rod - for extended warranty - in a new Rheem waterheater?


You are installing a combo anode rod that replaces hot water outlet nipple. This means you will have 2 anode rods, which doubles the anode capacity of tank, which can cause extended life of water heater, assuming that both anodes are inspected each 2-5 years.

Sounds like a heat trap insert is in the way.
Look at parts sheet that comes with product manual.
Pull insert out since it will cause clogs.
Same insert is on cold side nipple.

I want you to contact the Tank forum since they are anode experts:
http://www.thetankatwaterheaterrescue.com/forums/forum3/
Tank will recommend magnesium anode and not aluminum.

My understanding is that Rheem water heaters are made so only Rheem brand anodes fit their tanks. While other companies use generic anodes that are sold at any plumbing supply, and also sold at Tank website.

You can configure pipes to make heat traps that save save $2-4 per year on gas water heater operation.

C4 76 error code on richland waterheater


Richland tankless is made by Rheem.
C7-76 is communication fault with remote.
Turn off power at remote and wait 5 minutes, turn power back on at remote, and see if problem clears.
If problem continues, read below:

Before calling service technician, open following links for troubleshoot resources including error codes, Rheem chat, typical maintenance manual:
http://waterheatertimer.org/pdf/Rheem-error-code-C7-76.pdf
http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html

Tankless water heater, more than any other type of heater, need to be maintained.
Maintaining tankless will probably not affect C7 76 fault code, but can prevent many other common error codes.

More information is needed for correct do-it-yourself answer. Add a comment and include what steps you have taken and what you observed at the pilot light. Include description of gas control valve.
The combustion parts may need to be cleaned, the thermoscouple could be bad, misaligned thermocouple, the system locked out from FV flammable vapor event, or overheating caused ECO energy-cut-off to trip, or air in gas line, low gas pressure, or dirty air intake, bad venting, improper venting, bad gas control valve, negative pressure, tight house, lack of combustion air, hot attic, exposure to chemicals in air, rusted parts, etc.

I can not light the pilot on my reliance sta-kleen 502 (30 gallon) waterheater. please help


Reliance is Rheem
Replace thermocouple is best start point.
Example Whirlpool manual shows general replacement steps on page 22:
Buy thermocouple at hardware or home center. measure length before going to store.
http://waterheatertimer.org/pdf/Whirlpool-6510397.pdf

Utube videos show how to replace thermocouple

Many things can affect pilot:
Low gas pressure, Water or air or debris in the gas control valve, High-heat event causing ECO to trip requiring new gas control valve, burner and tubes needing clean-out, FV sensor tripped, loose or bad thermocouple.
Manual above shows general steps for doing some of these things, but service technician is probably best choice if thermocouple does not fix problem.

Gas water heaters require periodic maintenance.
If repairs cost more than $330, then buy new gas water heater and install yourself.
Use the old one for a solar collector.

I have a Rheem PG50T9A gas hot water heater. We had hot water this morning. When I came home the pilot light was out and won't stay lit. Any ideas?


Hopefully just the thermocouple. The thermocouple is the small rod right next to the pilot light. The flame on the pilot heats up the thermocouple and keeps the gas valve on. You can replace it yourself. The thermocouple will be connect by a small nut on the underneath side of the valve, and you will have to pull the thermocouple out of the pilot assembly. Not an expensive part, you can get it at any hardware store. Hope this helps you .

My hot waterheater will light but when i release the reset button after over a minute the pilot light goes out. what do i do


There is a small probe with its tip in the pilot flame called a thermocouple,
this is a flame failure device and shuts off the pilot in the event the flame goes out due to wind water or no gas, this device can become bunrt out usually after many years of use and can normally be replaced, you can purchase a universal thermocouple from most gas appliance retailers
