Old water heater with rust on bottom rim pilot won't light

This is a STATE water heater model CENSIBLE. It is older and the house hasn't been lived in for a couple of years. There is some rust at the base of the heater where it touches the basement floor. The pilot will not light. I cannot smell gas when I depress the pilot knob to light it. Is this a fixable situation? Any advice appreciated.

You have an old tankless computer and it won't work?
What would you do if you had old laptop computer that didn't work?

Copy following links for possible resources including required yearly maintenance so tankless computers can last 4-6 years before needing replacement:

Installed but not heating


State point-of-use electric water heater plugs in.
Check that outlet has power.

The water heater must be full of water or elements burn out instantly.
Test the element.
http://waterheatertimer.org/How-to-test-water-heater-element.html
http://waterheatertimer.org/How-to-install-point-of-use-water-heater.html

Match voltage to water heater:
This electric water heater, like all electric water heaters, will work on 120Volt, 208-240Volt or 3-phase unbalanced.
But wire size and breaker must match element wattage.
If you have outlet, check the wire size and breaker, and check what other devices are drawing power from same circuit, then add up total watts and compare with charts on link below.

Pilot light is lit but won't turn on water heater


What band and type water heater do you have? And about how old is the water heater? Add a comment with more information.

Following general information applies to tank-type residential water heater.
If pilot light is working, then thermocouple is good. Otherwise, if thermocouple was bad, or fallen out of place, then there would be no pilot flame.
Carefully read instructions for lighting water heater located on front of tank ... make sure you have the gas control valve set to ON.
At this point, troubleshoot varies widely depending if your water heater is older and air enters front of heater, or if water heater was made after 2007-9 and has sealed combustion chamber and FV system.'
Troubleshoot also varies widely depending if you have power vent and which type of gas control valve.
Copy following link for troubleshoot by type of gas control valve:

Rust in water heater tank


the tank needs flushed out ! heres how. Water heater manufacturers recommend flushing sediment from your storage type water heater periodically.
If your water heater is gas, set the gas valve to "Pilot" to prevent the burners from coming on while you are flushing it. If your heater is electric be sure to turn off the circuit breakers. With an electric water heater, if the water level drops below the heating elements and the thermostat turns the elements on, the heating elements will probably burn out quite rapidly. Connect a garden hose to the drain valve at the bottom of the tank, Close the shut off valve on the cold inlet to the water heater. open the temperature/pressure relief valve at the top of the tank by lifting the lever. Leave the valve open. Open the drain valve at the bottom of the heater allowing the water to flow out through the garden hose. when the water is clear your finished. close pressure relief valve on top of tank and turn water back on.
Open a hot water faucet in your house, and let it run until no air bubbles come out.

Turn the heater back on, and with gas units re-light the pilot light if necessary. good-day !

I purchased a home that has what appears to be an older Rheem Ruud rr410t 40gall (it states 175 litres). How do I determine how old it is and when it might need replacing? So far it seems ok, but not...


Label on side of tank has alpha-numeric serial number.
Look at 2nd and 3rd numbers in serial number.
For example C05... means water heater was made in 05 or 2005.

To measure if heater needs replacement, look for signs of water and rusting along bottom of tank.
Also listen for rumbling sound that says water heater has sediment build-up in bottom, and efficiency has dropped.

http://waterheatertimer.org/Clean-sediment-out-of-water-heater.html
http://waterheatertimer.org/9-ways-to-save-with-water-heater.html

If this is a gas water heater, then look at color of pilot light and burner flame.
If everything burns clear blue then water heater is working fine. If flames are yellow or orange, then combustion parts need cleaning.
Pilot is not blowing out, so the conditions needed for water heater operation are good.

Time to shop for water heater is before you need one.
For example buy scratch-n-dent water heater from local box store at a discount.
Look for box store coupons for Sears, Lowes, Home Depot, Ace, etc.
All brands of water heater are good > I recommend staying away from water heaters with blowers and electronics because parts are more expensive, and these water heaters are not proven more reliable or cheaper to operate, and are more susceptible to power surge.
Water heaters with longer warranty will last longer.
For gas: Install gas water heater yourself:

Rheem 22V50F1 pilot won't stay lit. Changed thermo couple & it lit, ran then went out. Let it sit overnight & it lit, ran then went out. What next? p.s. The unit is 5 years old. Thanks


If pilot lights and flame is robust and clear blue, and pilot goes out later, then some suspects can be excluded: air in gas line, low gas pressure, thermocouple is overtightened (finger-tight + 1/4 turn), thermocouple not positioned correctly in the flame, dirty pilot tube.
If flame is yellowish and small: then clean pilot tube and combustion parts.
http://waterheatertimer.org/How-to-install-gas-water-heater.html#clean
Remaining suspects can include: air in gas line, low gas pressure, bad gas control valve, tight house so household vent fans pull air down water heater vent that blows out pilot, hot attic with inadequate ventilation, water dripping down vent.

Reliance 606 natural gas water heater - model #640YORT - water does not stay hot. pilot has to be clicked to heat and then u can use hot water til tank empty and it will not continue to heat water.


If I understand correctly, the pilot light is not staying lit.
You light the pilot and water in the tank reaches temperature.
Once hot water is gone, then pilot light has to be lit again.

Gas pressure is good, and gas is flowing.
Thermostat is working at high end because it cuts off heating.
Vent is working because tank heats up.
Air intake is working.

Gas control thermostat might not be reading low temperature. Replace gas control valve.
Pilot tube might be dirty. Clean burner parts and combustion chamber, and air intake, and vent.
Backdraft might be blowing out pilot. Check for constant updraft by running water heater 5 minutes, and then light match under vent hood and see if smoke goes up.
Very hot air can put out pilot, especially when water heater located in attic. Add ventilation.
Improper vent might have water dripping back down into combustion chamber and putting out pilot light and rusting out the parts. Inspect for rusted parts and water.

Pilot light went out twice in two weeks. Now there is water under the tank area and water on top of the water heater housing


I think that you have rust issues with your tank, if the thing is more than 10years old replace it these things don't last forever you know!
