I believe the problem is that there is some kind of loose debris or possibly fluid in the gas line right before it ties into the unit. It probably got in there during installation.

Reliance 606 water heater was in flooded basement had few inches of water up to it now wont light. What to do?

This could be a tough one without being able to examine it. First, have you precisely followed the relighting instructions printed on the heater (turn the knob to "pilot," hold down the button, etc.)? One other thought: the gas pressure to the pilot flame is very low - if some water got into its little supply pipe it could keep gas from getting to the pilot burner device. You would have to disconnect the pilot tube from the gas controller valve and blow it clear, then try again. Dealing with this type of gas problem can create dangerous conditions if not done properly. If water got into the gas controller valve (the one with the knobs and buttons) it will have to be replaced. If unsure, consult a plumber.

Basemnt flooded water heater wont stay lit ever since, taken out burner assembly severl times now stays on long enough to heat water then shuts down soon after.replaced thermocoupler and have to lite...

Sounds like the air intake is clogged, and pilot and burner tubes are dirty.
All manufacturers say that flooded water heater should be replaced and not repaired.

You can clean air intake and burner assembly, and then next step would be to replace burner assembly and replace gas valve thermostat to see if functionality returns.
Expense of replacing parts is about half the cost of new gas water heater from box store, and still no guarantee that old heater will work.

Pilot wont stay on

Thermocouple has failed., replace thermocouple or dirty pilot assembly, not enough heat being genrated to produce the 30 mili volts D.C. current to hold the pilot valve open. Clean pilot orfice. Remove assembly and pilot tubing from gas valve. Blow into pilot tubing to remove dirt.. Make sure pilot flame is engulfing the thermocouple.

Have an Atwood LP water heater. When I light the pilot light and hold it for 30 seconds or more it stays lit but the burner tube will not light except for at the air/fuel mixture slits at the thermostat...

Yes, a good place to start would be to run a burner brush through entire tube to make sure all spider webs are out, then blow through again. If that doesn't cure it, double check your position of burner tube in chamber. Sometimes if it's moved into chamber too far, it will tend to back-up flame in to tube. I've had some that I re-installed and was sure I put it back exactly where it was before, but had to pull burner tube back approx 1/8"-3/16" to get a proper flame. Make sure it's centered in chamber as well.

The pilot light on my gas water heater continually goes out. I can re-light the pilot and get it going. The gas burners goes on runs for awhile. I'm assuming when that when the temp hits the desired temp...


The pilot assembly should look similar to the pic above. Depending on where you live, you may be required to hire a certified plumber to replace the parts. If not you can do it your self. Keep in mind if it's not staying lit you also need to check the thermostat and the thermocoupler before replacing the pilot assembly. There is a good chance it is just the thermocoupler going out. It is one of the first things to check when troubleshooting a pilot light problem with a gas water heater. A thermocouple determines if the pilot light is lit. If it's not lit, the gas valve fails. If that's the problem, replace the thermocouple.

  1. Shut off the gas valve on the water heater and the gas valve on the line near the heater. Remove outer and inner doors, and loosen the pilot and supply tubes and the thermocouple connections to remove the burner assembly.
  2. Step 2 Loosen the screw holding the thermocouple to the bracket. Remove old thermocouple. Bring it with you to the store to ensure you are buying the proper replacement.
  3. Step 3 Install the new thermocouple. Position the thermocouple so that the pilot flame heats 1/2 inch of the tip.
  4. Step 4 Reinstall burner assembly in the water heater. Tighten burner supply tube, pilot tube and thermocouple connections. Tighten thermocouple no more than a quarter turn more than hand-tight.
  5. Step 5 Turn on both gas valves. Check supply tube and pilot tube for leaks with soapy water. If soap bubbles, tighten connections to fix leak. Ignite the pilot light, and make sure the thermocouple tip is heating up. Replace inner and outer doors.

Pilot light on boiler

The plumbers repair should be guaranteed, give him a call back.
It sounds to me that the pilot flame needs to be adjusted or the thermocouple is not aligned properly or there is a draft that is blowing out the pilot.
Good luck...
