Question about Reliance & 50gal Electric Water Heater

1 Answer

I have a reliance 501 electric water heater. I tried to drain it but nothing came out the drain at the bottom. It is older than 15 years and I don't know if it has ever been drained. The hot water pressure is almost non-existent. What should I do?

Hello At 15yrs old you got your money's worth from that tank.But a new one might not slove the pressure problem.The drain valve is clogged with sedemient.Make sure the pressure is out of the tank and poke a skinny screw driver or something to start the drain.

Reliance 501 electric water heater


Reliance-Rheem may have changed away from generic parts so you have to buy special order parts from them.
I have not heard of this before for elements... but Rheem does that for other parts.
Avoid Rheem products.
Rheem also makes a 1-3/4" element to fit Marathon water heaters, instead of standard 1-1/2"
Actual thread size for standard water heater is same as 1" pipe, except straight thread instead tapered pipe thread.
See if 1" pipe will thread into water heater element opening.

Reliance 501 Hot Water Heating element for 30 gal tank, where to purchase


You do not need special parts.
Wattage is printed on end of each element.
Buy generic elements at hardware store.

I don't have a problem, just a question.....we are in the process of buying ahome and the hot water heater is a Reliance 501, 50 gallon tank....with serial number G94278175...I would like to know the...

1-letter month followed by 2-digit year

So it was manufactued in 1994. Most water heaters will last 5-10 years for gas and 10-15 for electric unless they receive yearly maintenance (flushing tank, cleaning) so it is already past its expected life span.

That being said, an electric water heater is more costly than a gas one. If I was in your place I would start saving to replace the unit with a tankless gas water heater, as soon as the house closed.

1992 Reliance electric water heater model 501 has two 4500 watt heating elements , there is no hot water.


Check the breaker and top thermostat and make sure they are not tripped. Move onto replacing elements if above is not the problem.
Turn water and power off to heater and attach a water hose to bottom of heater to drain down tank. May have to open hot side on a facuet to get it to drain.
Once drained remove elements with 1 1/2" found at local hardware stores. once elements removed and new ones in place. Turn water on and get the air out of the system. Once water is flowing from the hot side from all of facuet's in house.
Once all air is out now yaou are resady to turn power onto heater.

What is the expected useful life of a Reliance 40 gallon electric water heater? Is there a maintenance step that can be taken to ensure that there is no build-up of contaminants on the elements?


The average life expectancy of any water heater relates directly to its warranty. 1 year- 1year, 6 years-6 years. If you use the water heater past its warranty, you are really making money on the purchase.

Installing a new anode rod is about the only maintenance step you can take. However, this does not guaranty that you will not accumulate build up.

Draining the water heater once a year helps a little bit with buildup in the bottom of the tank but not the elements.

The ultimate solution is to install a water treatment system, not just a water softener. They are somewhat expensive, but well worth the cost in the long run-10 to 15 years.

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
