Question about Rheem Water Heaters

1 Answer

Rusty colored water from hot water- is a gas heater and I replaced all the water pipes with new recommended lines and even added a water filtration system (whole house). The water heater built and installed in 2003 but this is a 1930 house so pipes old until I replaced in 2010 (May).

Hello,The "rust" is from the water itself.If the supply has a high iron content the process of heating it up seperates the iron out and over time it will form deposits on the bottom of the hot water tank.Locate the tank drain and connect a hose and open it up and let it run "flush" out the tank.Do this every month to keep it from building back up.It should be mentioned that the drain valve can be plastic and or very hard to close once it has been opened.They sell a brass drain end cap or the drain can be replaced with a new (long stem)drain.

Can i use the pipe ihad for my 40 gallon hot water heater


If you had a tank-type heater, and installed tankless, then you cannot use the same gas line pipe. You must have 1" gas line running to within 10' of tankless unit, and then 3/4" to tankless... and you cannot use flexible gas line.
You can use same hot and cold water pipes, but install service valves so you can delime the heat exchanger each year.

When I run hot water for the tub, it has a brown tint


10 year old homes today usually do not have galvanized pipe. They have copper or pex plastic pipe. These do not rust.
Is rusty water on both hot and cold line, or just hot line?
Just hot line, then check anode rod and flush tank:
http://waterheatertimer.org/Replace-anode-rod.html
http://waterheatertimer.org/Clean-sediment-out-of-water-heater.html#flush
Are you on water well? Well casing can get rusted. Water can have minerals. Call local water well service and describe problem in detail.
Are you on city water or mudd district water? Is pipe coming into house made of galvanized? Look inside meter box or look at pipe coming into house. Sometimes the city water line at end of run can get filled with sediments that will discolor water. Have water company flush the city water line.

My Rheem tankless water heater has been flashing a C8 and 76 code. I can turn off the heater using the power button on the unit, but my hot water will only last for a shower or so. Any suggestions? ...


Before calling service technician, open following link for troubleshoot resources including Rheem chat and contact, possible manual, error codes, etc.:
http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html

C8 76 is generally bad PC board. Call 800-432-8373
Just like a motherboard on your computer, the tankless PC board is operational center of tankless water heater.
Various sensors gather information from water pipes, gas line, vent pipe, and air supply to determine when to activate burner.
Most people understand that when their computer motherboard needs replacement, that computer will probably not work reliably again.

Tankless is basically connecting a complex computer to your plumbing and electrical lines and to a gas burner with a vent pipe to outdoors, despite knowing that plumbing lines, vent pipes, gas burners, and household electrical systems have plenty of problems on their own.

Age factor: When tankless is new and everything operates perfectly, the tankless works correctly.
And each tankless manual recommends yearly and monthly maintenance, just to maintain operation, the cost of which can exceed the expected 1-8$ monthly savings. And who wants to clean the water filter each month and delime the exchanger every year?
http://waterheatertimer.org/pdf/Tankless-maintenance.pdf

Don't buy a tankless water heater because the only folks promising unlimited hot water and effortless water heating experience while saving money with a tankless are the tankless promotors.

Solve most tankless problems yourself, same day, any brand for about $350.

I have a reliance 501 propane gas water heater how do i change a thermostate


Hi,

To change a gas hot water heater thermostat you will need to first buy a new gas valve for your hot water heater. The gas vaive and the thermostat are integrated into one unit.

To replace the thermostat on a gas hot water heater you must follow these procedures....

1. Turn off the incoming water and drain the water heater.

2. remove the pilot tube, the burner gas tube and the thermocouple from the gas valve. Turn off the gas line and remove from the gas valve.

3. get a pump pliers or a wrench in behind the gas valve and turn the whole assembly CCW to remove it from the tank.

4. After appliying pipe dope or tape to the new gas valve threads, turn the new gas valve into the tank by turning in a CW direction. Be careful not to damage the small wires to the ECO. They are the little red wires on the back. If you break them the assembly is irreparably damaged.

5. reinstall the gas line, thermocouple, burner tube, and the pilot tube to the gas valve.

6. Fill tank with water. Make sure to open a hot water faucet and purge all air from the tank.

7. Check for leaks where the gas line hooks up with soapy water.

8. Relight pilot light and check operation.

9. Set the new temperature setting to a medium setting and then adjust the temperature to your likeing from there and adequate time for heating completely.

My reliance sta-kleen 502 is leaking. The water is dripping on top of the pilot light, extinguishing the flame . Please advise me with step by step instructions to diagnose and attempt fix this myself....


If you have a leaking water heater there is a serious problem.
http://waterheatertimer.org/Water-heater-leaking.html
Page shows how to limp along on a leaking water heater if your water heater needs replacement.

One of three things is causing the water:
1) Loose water connection on top of tank that is dripping down inside tank >> check pipes on top of tank.

2) The vent is clogged or not working correctly causing condensation inside flue pipe.
Condensation water is dripping back down inside tank.
Problem means possible CO poisoning if gas is not venting.
Look at vent pipe to see if joints are corroded.
Use long fireplace match > light match and put into draft hood at top of tank and see if smoke goes up.
Put hand at draft hood opening when water heater turns on to see if vent gas enters home.
Do same test when furnace turns on to see if furnace vent is pushing back into water heater.
Does water heater vent inside same pipe as furnace? You may need to set up separate vent for water heater if furnace gasses are pushing back into home.
Check furnace vent for obstructions.
Look at vent stack top of home to see if hood is in place.
Check if bird nest is built inside warm vent pipe.
Improper flue is top priority for getting fixed so vent gasses properly escape home.
You may have to call a plumber.
Professional plumbing forum:
http://www.thetankatwaterheaterrescue.com/forums/forum3/

3) Your water heater is rusted out.
A rusted tank has to be replaced.
It cannot be repaired.
However, before replacing tank, you do not want a tank failure where tank ruptures and water runs inside home until water is shut off.
This will cause major damage.
Protect yourself first.
Turn off water valve above tank.
Move gas knob to 'pilot' so burner is not heating water.
Open tub spout on hot side to relieve pressure on tank so it will not rupture.

Now you're protected.
Link above shows how to limp along on failed tank until you can replace heater.

You need a new gas water heater from Lowes or Home Depot
Look at label on side of you tank for gallons and btu's of your water heater.
Measure height to flue pipe so you get same height water heater, so pipes don't have to be changed.
You need a pipe wrench and teflon tape which will be wrapped on each pipe thread when pipes are reassembled.

Step1) Drain water heater using valve at bottom of tank.
http://waterheatertimer.org/Water-heater-will-not-drain.html

2) Turn off gas valve going into heater.
When gas valve is perpendicular to gas line, then gas is off.
Dissemble gas line to water heater.

3) Disconnect flue pipe and support flue pipe with wire so it doesn't not fall down. Flue pipe joints should be held together at each joint with 3 screws.

4) Turn off water. Shut off valve is on COLD side.
Disconnect water pipes.

5) Move old water heater out of way.

6) Set new water heater in place. Put water heater in drip pan.

7) Connect water pipes >> cold goes to side marked cold.
Hot to hot.
Buy new flexible water connector pipes at home center for easy installation of water pipes.

8) Connect gas line exactly as it was connected before.
Home center sells flexible gas line connector for easy installation of gas line.
To test for gas leak after installation, mix liquid soap with water and put around gas line joints to see if there are bubbles.
Natural gas has less pressure than water lines, so gas pipes are easy to seal with ordinary wrench.

9) install TP pipe that runs to floor. Use old one off old heater.

10) Fill tank completely with water until water is coming out of tub spout.

11) Turn on gas, and light pilot as shown in manual.
New gas heater sometimes have small water leak when first fired up, so ignore a bit of water.

12) Save water heater manual like it is gold, and read everything in manual.

It sounds like you need to replace it, Actual cost can very widrly depending on your location but I would say $350-400 is probably close. Plus installation unless you can do it yourself. Hope this helps. Thanks

Natural gas hot water heater not stying lit


Probably a bad solenoid in the gas valve. Higher voltage of a new thermocouple keeps it open longer but it still fails over a period of time. Look into a new gas valve for the water heater.
