Question about Water Heaters

2 Answers

Under advice from handyman service friend opened access to burner assembly due to moisture in area following tank drain and flush. Pilot stays lit but burner fizzles out when tries to ignite. Found a very large amount of soot and debris which could be blocking air vents in addition to moisture. Shop vac picked up some type of clip which I believe probably clips burner assembly down to fitting below back of burner assembly to bottom of tank assembly. Unable to find a repair manual showing drawings of burner assembly.

    I was in the middle of e-mailing support I forgot to List Model - Rheem Gas Hot Water Heater Fury Series, Model 22V30F (sticker on unit says Model 22V30FSQ, but only have found on-line references to Model 22V30F). Unit was manufactured 09/2007.

    there only appear to be moist areas around the out side of the combustion chamber now, the burner is dry and is not corroded, there was just A LOT of soot. The moisture appears to be still along one wall and this wall moisture/intake airflow isssue was following just a drain and flush. None of my hose/pressure control valve fittings could have allowed any water inside the tank. How important could this clip I found be since I don't know what it holds/connects? Am I OK to relight burner? (pilot is burning fine or should I contact Rheem tech services in the morning (I assume they are not open 24 hrs.). How could moisture be present on this interior wall in the combustion compartment? Should it be there? I assume if it is normal it would just dry with the burner on. One last thing, is it normal for there to be a lot of soot on top of the burner, on the floor of the combustion chamber and in the vent pipe? Thank you so much for your help!

    Spoke to contractor Sat morning after reporting problem. Had removed all soot in the burner area but still starving for oxygen. Turns out Rheem hot water heaters have a glass piece at the bottom that is part of their safety design. The contractor and Rheem agreed that is was that part that broke and was suffocating the burner (contractor said this is a problem with the Rheems even though the water heater was 4 years old). Contacted Rheem to get warrantee replacement authorization and they refused saying the model was not certified for mobile homes. Both contractor and plumbing supply warehouse we use said Rheem is one of the worst for coming up with ways to avoid paying their warrantees. Discussion with the contractor suggested the large amount of soot was most likely due to poor combustion in the heater. Much of the air intake screen was clogged with spider webs and dirt. My handyman friend and I replaced the water heater with an American Standard (all of their units meet mobile home standards and normal residential). I'm out almost $500 and we threw away a tank less than 4 years old -what a shame. In addition to cleaning and clearing the existing vents, we are adding additional intake venting to make sure both the hot water heater and the furnace unit both get enough oxygen. Thank you for your help.

Hello paul... these hot water tanks should actually get thorough cleaning every 6 months, most do not get a look until they don't work. Once you have all of the soot out of there use compressed air to clean each of the vents.

Next, clean the vent pipe and inspect that vent or chimney all the way to the roof and out. If it is needs a cleaning do so. The moisture can be a sign that the vent pipe is partially blocked.

Once all of that is attended to, then since the pilot is working, fire it up. The moisture you have noticed in there could be the result of a hair pin leak or 2. That small amount of moisture should not be a problem.

    Great.. that's what I was water heater...

    now the SQ or what ever on the end should not change should be able to use what you found...

    Was the unit under water??? or just a moist area...???

    I'm thinking that the burner is corroded to the point where it will need to be replaced...especially if you lost that clip also...

    They are very hard to rehab if they get all corroded...

    The best thing to do may be to contact Rheem tech. services directly and see if they have drawings and/or parts....

    My experience has been that ALL of the new water heater designs since the anti flash back stuff took effect, have been less then good....

    Also, I have had trouble with warranty with many of them also....

    You would think they could honor the warranties better with the way they jacked the prices on the new ones!!!

    I understand your frutration and want to tell you that your plumber professional really took care of you if you got the new heater and had it installed for $500.00.. you owe him a big Thank You also!!!

    Glad you are back in business...!!

The pilot won't stay lit on gas hot water tank.

Make sure thermocouple tip is seated inside the burner flame.
Make sure thermocouple is not overtightened. Finger-tight + 1/4 turn.
If the pilot lights, then ECO energy cut off is not tripped, but gas control valve might be bad.
Check color of pilot flame: it should be strong and clear blue.
If pilot flame is weak, or color of flame is yellow-orange: Clean pilot orifice and burner and combustion parts on yearly basis.
Clean air intake screen if applicable.
Increase air supply to water heater. Open a window and see what happens.
Check for adequate draft going up chimney using match under vent hood to see if smoke drafts immediately upwards.
Bleed air out of gas line.
Check gas pressure.

How to Change the Gas Valve and Thermostat on a Hot Water Heater

<p>If you are having<b> trouble with the temperatures</b> of your <b>gas hot water heater</b> fluctuating too much, or after <b>changing the thermocouple</b> of your gas <b>hot water heater</b> then you may need to change the complete <b>gas valve and thermostat assembly</b>. Also if you have changed the <b>thermocouple</b> and the pilot still will not stay lit, then the gas valve could be bad or the <b>ECO (Emergency Cutout)</b> may have activated and is open. This is a onetime device and cannot be replaced.<br /> <p><br /> <p>These instructions are for the older style <b>gas valve and thermostat combination</b>. These commonly have a large red knob that adjusts the temperature of the water. Also note that the burner tube nut for <b>natural gas</b> is right hand thread, but if you have <b>LP or propane gas</b> the burner tube nut is left hand thread.<br /> <p><br /> <p>The newer <b>gas valve thermostat combinations</b> that have come out recently are similar, but they have a well in the tank that the sensor slides into. The assembly is held fast with a set screw. With this type of <b>gas valve and thermostat unit </b>the tank does not need to be drained, but most of the rest of the change out is similar.<br /><br />To change a <b>gas hot water heater thermostat</b> you will need to first buy a new gas valve for your <b>hot water heater</b>. The <b>gas valve</b> and the <b>thermostat</b> are integrated into one unit.<br /><br />To <b>replace the thermostat on a gas hot water heater</b> you must follow these procedures....<br /><br />1. Turn off the incoming water and<b> drain the hot water heater</b>.<br /><br />2. Remove the <b>pilot tube</b>, the <b>burner gas tube</b> and the thermocouple from the gas valve. Turn off the <b>gas line</b> and remove from the gas valve.<br /><br />3. Get a <b>pump pliers</b> or a<b> wrench</b> in behind the gas valve and turn the whole assembly CCW to remove it from the tank.<br /><br />4. After applying 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 <b>ECO</b>. They are the little red wires on the back. If you break them the assembly is irreparably damaged.<br /><br />5. Reinstall the gas line, thermocouple, burner tube, and the pilot tube to the gas valve.<br /><br />6. Fill tank with water. Make sure to open a <b>hot water faucet</b> and <b>purge all air from the tank.<br /><br /></b>7. <b>Check for leaks</b> where the gas line hooks up with soapy water.<br /><br />8. Relight pilot light and check operation.<br /><br />9. Set the new temperature setting to a medium setting and then adjust the temperature to your liking from there and adequate time for heating completely<br /> <p>

Pilot wont stay lit on waterheater. I replaced Thermocouple and that did not fix it. It will stay lit on vacation setting.

Most gas water heater problems can be fixed with yearly service that cleans burner and burner parts, checks gas pressure and bleeds air out of gas line, cleans air intake, and checks for venting and air intake problems.

Most gas water heater problems can be solved by having service technician perform yearly maintenance. Or by doing maintenance yourself.
This maintenance includes cleaning burner parts and combustion chamber, checking gas pressure and supply, bleeding air out of gas line, checking vent draft, making sure air supply is adequate and not exposed to chemicals, cleaning air intake. Also adjusting flame sensor so it is positioned correctly. If water heater is connected to electric circuit, the outlet must have correct polarity.

You can get gas to appliance indicates the gas control valve and water heater are not locked out. But the gas control valve thermostat can still be bad.

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 .

Pilot light on water heater wont stay lit

The thermocouple has failed. It is the temp probe that goes from the pilot lite burner area to the control valve. Go to your local plumbng repair shop and buy one. Most appliance parts stores have them also. Take the old one with you and they will hook you up with an exact replacement. They are not that hard to change. Usually a nut or 2 screws in the temp bulb area at the burner end and a nut that threads into the control valve.
Make sure before you install the new one that the area where it mates to the gas valve is clean. Should be about a 20 min job including clean up with replacement parts in hand.

Pilot lighting

1) Open the door on the bottom of the tank to show the burner. 2) Turn the valve to "pilot" and depress. 3) Light the match, (best if you have a candle/grill lighter), and follow the skinny copper tube from the valve to the burner inside (this is called the thermocoupler). At the end of it, you will see the pilot. 4) Once pilot is lit, keep valve depressed for a minute (this warms the thermocoupler, thus sending a signal to the valve saying the pilot is lit). 5) Let go of the pilot button (usually red). 6) If pilot stays on, put the door(s) back on and turn the valve to "on". You will hear/see the gas ignite when complete. Good luck!

Cant get my waterheater lighter to reignite

Sounds like the gas valve has failed. The gas valve can be replaced. It will unscrew out of the tank. Shut the water supply to the tank off and get the new gas ready to screw in. Take out the old and screw in the new, you will onlt lose about a cup or two of water if you are quick enough. Otherwise drain the tank down if you must. If you are going to replace the gas valve I would also replace the thermocoupler.
