SOURCE: Reliance gas water heater 40 capicity, has a leak on the top

Most likely only one of the pipes is leaking but weaping enough to cover the top and indented places near both inlet and outlet. This leak has most likely penetrated all the insulation and is a problem throughout the tank wrap insulation...If you are able to blow air continuously long enough to determine which connection is leaking then fix it. It will likely to take quite a while to dry out all the insulation if the water has migrated down into the tank wrap... If you determine that the insulation is waterlogged, you may be able to drill several small holes in the external cover.
good luck

SOURCE: need to empty reliance 501 hot water heater how?

1) Shut the breaker off to it at the panel. 2) Hook a hose up to it (the bottom has a drain). 3) Close the valve to the water heater (on the cold water supply). 4) Open drain on the bottom of water heater. 5) Open the relief valve to allow air into the tank (it won't drain otherwise - think if you put your finger on one end of a straw - the liquid stays in until you let go). Why are you draining it by the way?

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.

How to connect electrical ground for gas water heater 5 50 NKRTO


there is a lot of controversy over this. The reasons that you may want to do it are because of cathodic erosion. If the water has high mineral content it can shorten the life of the tank. If you are using plastic pipe in the house it can affect the situation also. All that aside, the reason for the grounding is found in the National Electrical Code and is in section 250.140 . The reason is that the code calls for grounding of all other metal piping systems that do not carry water. That would mean the natural gas line! The reasoning is because if something happens and energizes the gas line and it is not grounded it could cause a fire or an electrocution hazard. The code calls for a ground wire of sufficient size to handle a stray voltage of the amount that would be most likely found in the application. So you have 220 VAC in most residential applications. That would mean that you should use something in the neighborhood of about # 8 to # 12 AWG as a ground. There are charts to determine the exact size. IT depends on the length of the run.. The wire should be connected to the area closest to the control head if the head is not insulated from the pipe and then run to an electrical ground nearby. The installation has to be done by an electrician and not a plumber unless you do it yourself IF YOU ARE THE OWNER OF THE HOUSE AND IT IS NOT A RENTAL.

How to replace elements


The elements usually unscrew after power is shut off and wires disconnected. A large box wrench or socket wrench is applied to the hex part under the wire connestion terminals. The elements may be difficult to remove if the heater is older and the connection is rrusted or corroded

Used, Reliance 805 is power vent gas
10 year old water heater that is newly installed.
Unknown gas control valve.
I'm not a fan of installing old power vent water heaters.
Usually these things are so expensive that old one is only replaced when it fails.

120Volt Outlet must have correct polarity and unit must be grounded between ground prong on cord to manifold tube connected to bottom of gas control valve. Test for continuity with multimeter.

Is this an early FV model with air intake located on bottom?
If air intake is clogged with dust, then combustion chamber overheated and tripped FV system. The older heaters need replacement parts and new gas control valve, or entire heater must be replaced.

Replace gas control valve.

Water is leaking from the pipe on the top of the tank (Reliance 606 electric) where the hot water comes out and goes into the house. Likely causes?


If tank is rusted out, then that is caused by depleted anode rod, or tank that is not electrically grounded on hot side pipe.
If pipe nipple is rusted out, then that can be caused by improper connection between copper and galvanized pipes, and caused by non-grounded hot water pipes.

If tank is leaking, replace it.
If nipple is leaking, remove with pipe wrench, apply teflon tape or joint compound on threads, and install new nipple. Replace anode rod if possible. Correct copper-galvanized connections. Add ground wire between hot and cold pipes.

The problem requires looking at manual and service handbook, except handbook doesn't show most recent water heater.
My first check point would be gas supply, and then vent draft, and then air supply.
Take off front cover and try lighting again to make sure air supply is not problem.
Review lighting instructions.
If there is no gas, and gas is turned ON, then gas control valve is suspect.

I have a 1992 bounder mh ,6a6e atwood water heater.I recently replaced the coach batteries and main battery.My circuit board went bad,replaced along with eco and thermostat.My gas valve was rusty and...


First check thermal cut-off that is connected between incoming power wire and thermostat terminal. (located inside little clear plastic sleeve) Easiest way to do that is to remove it from the circuit temporarily. Just pull it off thermostat terminal, pull it apart from other end, and just connect female spade from incoming power wire directly to thermostat terminal. Then see if water heater ignites. If it does, and all works well, get new thermal cut-off. That cut-off is a safety feature in case of flame up at burner, it will shut off gas supply. It is not reset-able, just works once then needs to be replaced.
If that doesn't cure it, take a 12v test light, or a multimeter, and test for power at gas valve, when water heater is trying to ignite, or at ECO terminal where red wire runs from left ECO terminal to gas valve. If power is getting to gas valve, and you don't hear or feel it click, make sure ground connection is sufficient as well. If you have 10.5-13.5 volts to gas valve, and it's not opening and ground is good, then it's faulty and should be replaced. If it is clicking, (opening) but no gas coming through, you may have a plugged orifice on gas valve, provided you have cleaned burner tube of any spider webs or debris previously. If no voltage from red wire, start back tracking with meter or test light to other terminal on ECO, then to terminals on thermostat as well. You'll see how feed wire (short jumper) goes from thermostat, over to ECO. Remember, you will have to hold test light or meter probe at connection and have someone turn on switch to get a reading, which will only appear when it's trying to ignite. Let me know what you find.

if its a 240 volt unit,then yes they are both 120 volts for each phase and the 240 volts for combined pair to each terminal on the units thermostats terminals,hope you have a white or green or both for a safety ground though just in case there;s plastic water lines between the supply and the unit

The water gets too hot and trips the reset on the thermostat.


Two possibilities. 1 failed upper or lower Tstat 2 Shorted element
To test element: disconnect both wires to element terminals. use continuity tester to see if there is continuity through element (one probe on each element terminal) If no continuity element is bad. Then test for continuity between each element terminal and the water heater itself.( one probe on element terminal and one probe grounded on bare metal or inner tank.) If there is continuity from terminal to ground, element is bad and also can cause tank to continue heating even when thermostat shuts off. This is because the thermostat only shuts off one pole of the 220 and a shorted element can continue heating from the 2nd pole.
If both elements test OK and water heater heats the full tank( tank feels hot at bottom element access panel when no hot water for 2 hours) most likely the lower thermostat is bad.
