Question about RELIANCE ELECTRIC WATER HEATER

2 Answers

I tried to drain my electric water heater. After about 30 or so gallons drained out of a 50 gallon tank, the drain clogged from the inside. Turning the cold supply back on didn't help, and now my water heater is full again, the drain won't let water out, and I have to pull out the lower heating element for replacement.

The "sacrificial rod" is actually there to prevent the heating elements from being eaten away. by electrolysis. If the deposits in the bottom of the tank are simply from sediment from your water, the tank may be fine. You won't know though until you get the tank drained and inspect the elements. The drain valve screws in just like any other piece of pipe if that helps you get it drained, or a piece of wire through the valve may work but you might damage the rubber washer in the valve. Once drained, and the element removed, inspect the element. There should not be any fissures in the element if you have an otherwise healthy tank. visible blowout usually means the rod has failed.
The presence of heavy deposits indicates hard water, which results in shortened tank life.

Hi..my name is Keith...you can try to blow air into the drain valve to unclog the debris and see if it will drain..but if it has that much debris i think i would replace the hot water heater..also it has a sacrificial rod inside of it..and if it is melted away then the water will eat at your heaters liner and will eventually eat a hole in it...i hope this has helped

I have replaced this old water heater. But I am not able to get the water out of this water heater. There are some sediments and water it not coming out. How can I empty the water?


I had the same issue a few months ago. To clear the sediment blow back into the hose making sure the valve at the tank is open. I had to blow two or three times during the draining process. 50 gallon tank took about 45 minutes to drain

My son used the hose to put about 5 gallons of water down the exhaust vent. Now (surprisingly) it won't work.... Ideas?


Maybe I should look at your unit but, I'm not familiar with an exhaust vent on an electric water heater. That being said, I can't find your system, I did look, if your have 5 gallons of water inside the metal outer tank, I hope it tripped the breaker. If it didn't, you had better turn it off. The only thing you can do really is, pull the inspection panels off, if there is a small piece of insulation covering the thermostats, pull them out. You're going to have to let it drain, air dry. Only the lord knows how long that will take. There is insulation between the fiberglass inner tank and the metal outer tank so, I would have to guess it's pretty saturated with five gallons of water in it. Is this actually a gas heater?

Only a trickle of hot water is coming out of my faucet. I tried to flush the tank, but only a trickle continues to come out of the hose....am I not doing something right?


http://www.waterheaterrescue.com/pages/WHRpages/English/Troubleshooting/Tanklets/backflushing.html
The link above gives a list of reasons for the decreased water pressure at your faucet.

As for draining the tank, it sounds like it's clogged with sediment.
http://waterheatertimer.org/Clean-sediment-out-of-water-heater.html

To open a clogged water heater:
Connect a washing-machine-hose to water heater drain valve.
Connect garden-hose to outdoor spigot, and to washing-machine-hose.
Turn on outdoor spigot for 10 seconds and it will open the clogged valve.

Energy smart hot water heater not giving ample amount of hot water both elements ohm at 12.5


element-connection-450.jpg
For images and product information
For manual


You checked ohms, did you check for 240V across lower element when lower element is turned on?

Energy smart electric water heater
has a control box on top of unit. Water heater does not have typical thermostats that can be tested and replaced. Temperature sensors located above each element send information to control box through small black and red wires. Temperature sensor sells for about $40, but there is no test listed that shows how to determine when sensors fail.

Potential problems:
-Temperature sensor is not reading correct temp
-Control box not processing correct temperature information
-Selector on control box set to 2, 3 or 4
-Thermostat temp on control box set lower than 120 degrees F
-Sediment build-up starting to surround lower element so water doesn't circulate (see if drain valve runs full-open

What cause the water heater to take more than an hour to heated up and unable to last longer. Usually its take about 15 min. to heat up and can last longer.


'Rheem 81VP15S point of use' is a single-element, 15 gallon, 120V electric.
Other 'point-of-use' sizes range from 2-1/2 to 6 gallon to 20 gallon.

Electric water heaters have 2 parts: thermostat and element. One is not functioning correctly. Most likely the element caused by sediment build-up.

How to determine if tank has element or thermostat problem:
Do not turn off water going into tank. Put hose on drain valve. Open drain valve. Does water come out like open spigot? If water does not flow, then heater is likely clogged with sediment.

Solution 1: If water flows out like a spigot, the thermostat is probably bad. Read: How to replace thermostat.

Solution 2: Water does not flow, so element is surrounded by sediment build-up and cannot heat water. You need to clean out tank with shop vac, and put in new element ... plan full day and 3 trips to hardware store. Simply draining tank will not remove sediment. Sediment is chunky and will not come out voluntarily.

Buy element before starting:
-Turn off electricity
-Open cover on side of tank, remove insulation (these have to be put back for proper operation of thermostat)
-The are 2 electrical parts >>the element and the thermostat which is located above element
-Element wattage is printed on element and also shows on label on side of tank
-I think Rheem element is held in place with 4 hex bolts
-Take photo of element to hardware store so you have part on hand before removing old element
-If element is 1-1/2' diameter hex type, you need inexpensive element wrench from hardware store + the element

Drain tank and clean sediment:
