Hot water heaters typically don't last most then 20 years or so. AO Smith used to sell glass lines tanks that lasted longer, but were fragile. Areas with acidic water, like the west coast, tend to go quicker.
The new tankless heaters cost more, but don't waste energy heating up water over night.
A large house may need more than one tankless however, because you don't want temperature variation when someone is taking a shower and someone else wants to do laundry or dishes.

Unit is probably rusted out:
http://waterheatertimer.org/Leaking-water-heater.html

Reliance is AO Smith. I recommend the AO Smith line-up of water heater brands as best because air intake screen is located on bottom of unit and can be cleaned by homeowner without removing combustion parts, and because AO Smith posts service manuals.

Reliant 501 Natural Gas won't stay lit


Reliance water heater?
Thermocouple is good if the pilot stays lit continuously.

501 is older model. Unknown if this unit has FVIR protection and sealed combustion chamber or open air intake on front of unit.
http://waterheatertimer.org/pdf/Reliance-2006-Service-Handbook.pdf

With FVIR protection:
Get more fresh air to the unit.
Clean the flame arrestor screen.
Test and replace the thermocouple:
http://waterheatertimer.org/How-to-test-water-heater-thermocouple.html
Inspect and clean burner and combustion parts
Test gas pressure, bleed air out of gas line.
Replace gas control valve.
Test draft air by lighting match and see if smoke is pulled into the vent pipe at draft hood on top of tank.

My reliance 501 is leaking at both entry hoses ports and also is very hot to the touch near the electrical connection port on the top of the water heater.


Emergency steps:
Turn electric power off.
Release tank pressure by opening bathtub faucet on hot side.
Turn off water supply to heater.
You can turn water heater ON for short periods (1/2 hour) to make some hot water until repairs are made.

It sounds like runaway heating caused by shorted element, possibly caused by leaking water. But I cannot tell for certain what the problem is. Read following links and/or call plumber.
http://waterheatertimer.org/Leaking-water-heater.html
http://waterheatertimer.org/How-to-troubleshoot-electric-problems-with-water-heater.html

Over-amping:
Look at watt rating label on side of tank.
For example 4500 watt water heater requires 30 amp breaker and 10 gauge wire.
If you have 20 amp breaker and 12 gauge wire, then change elements to max 3800 watts. Tank will heat more slowly.

You have to fix leaks, and I cannot see that problem. Call plumber or repost question with clear description of leak.

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.

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?

I have a Reliance 501 gas hot water heater that needs a tank cleaning. Scale is showing up in faucet aerators. Is it still comon practice to delime hot water heater tanks? If so any recomendations?


hook up garden hose to faucet @ the bottom of the tank and drain the hose to the outdoors or down a floor drain and open the valve , leaving the cold supply valve on , let it run until it runs clear , this will get rid of some of the sediment deposit that form at the bottom of tank , is the most effective way i know , good luck
