You say a very new water heater. You won't get 40 gallons of hot water from a 40 gallon water heater because the continuing influx of cold water will cool your hot water down. However, it appears that your bottom water heater element needs replacing. If the top element is bad, you'll get no hot water. If your bottom element is bad, you'll get "some" hot water. Try replacing the bottom element. DON'T FORGET to turn off the electricity AND water first (closeby towels are also handy)!

    The top element heats up the water in the top of the heater first. After the upper water is heated, THEN the bottom element turns on and heats the water in the bottom of the heater. Yes, the bottom element sounds like it is bad. It is probably either a screw-in type or has four bolts holding it in. If it is the screw-in type, purchase a socket at your hardware store that fits over it and screws it out of the heater. After making sure it is safe, you can change one of these in less than two minutes.

They worked on our city water and now i'm getting no hot water... before that it worked but i don't think to capacity.. it wouldn't fill the tub before getting cold.... it is a rheem 50...


As long as the water heater is not leaking or not big enough that would be the only reason to replace heater. If you are running out of hot water or it's cold, check the power source first to make sure you have power to heater. Then check the reset button on the top thermostat and make sure it's not tripped if it is it wil not heat. If so press red button aloow it a little time check for hot water.
Next step woul dbe to turn power off and drain water to replace both elements out. Once changed out turn water back on and open a faucet to remove air out of the wtare lines. Once you get water flowing out of water lines now you are ready to turn power back on. allow about 30 to 40 monutes and you should have hot water.

How do I fill water heater


Once the hot and cold pipes are connected to water heater, then open bathtub spout on hot side, turn water on so tank begins to fill.
After tub spout is running full stream without air, then water heater is full and it is safe to turn on the heater.

Turning on gas water heater before tank is full can damage tank.

Turning on electric heater before tank is full will burn out elements. Replace elements.

How do you set tempature to make the water stay hotter longer? I have a Rheem 82v66 2 (65 gal) and cant fill my bath tub with out running out of hot water.


65 gallon water heater should fill more than 1 bathtub since typical bath only uses 12-14 gallons hot water. First hour delivery on your tank should be greater than 60 gallons.
http://waterheatertimer.org/Hot-water-use-chart.html

Since you have such a small amount of hot water, it sounds like bottom element is burned out, or one of the thermostats is bad. There are two thermostats, and two 4500 Watt elements on 65 gallon tank.
If upper element was burned out, or water heater was not getting 240V electricity, then you would have NO hot water. So we know upper element is good and circuit is good.

Ordinary tank-type electric water heater is fully repairable by homeowner and parts are available at hardware or home center.
I suggest taking 30 minutes and doing troubleshoot before replacing any parts.
Buy cheap multimeter from home center.
When testing voltage, rotate multimeter dial to 240-250-277 VAC
When testing elements or continuity, rotate dial to Ohms.

I have a Rheem 40 gal. tank that is leaking water front the top where the vent stack is. It is pouring out. Can it be repaired?


A leaking water heater cannot be repaired, assuming it's the tank leaking and not nearby water pipe.
http://waterheatertimer.org/Water-heater-leaking.html

First thing is to protect your property from catastrophic tank failure where tank ruptures and water runs until it is shut off:
Tanks are under pressure when they are hot.
Close cold water shut-off located above tank.
Turn control knob to 'pilot' so pilot is lit but burner will not turn on.
Open hot side on tub for few moments to relieve tank pressure.

Now your property is safe.
You need a new water heater.
In mean time, gas water heater makes 41 gallons hot water per hour.
Shower used 5-9 gallons hot water.
Bath uses 10-15 gallons hot water.
You can turn on water heater for short stretches and limp by until you get a new heater.

Leeking water from bottom


I wrote a page on leaking water heaters with resources and information:
Page lists things to check.
http://waterheatertimer.org/Water-at-bottom-of-water-heater.html

Also run hand over tank to find warm spot that says where leak is coming from
A rusted tank cannot be repaired.

If your tank is rusted out, it might burst open and flood the area.
Hot water inside tank is under pressure.
Turn off heat source to water heater.
Turn off water valve located above tank.
Open tub faucet on hot side and relieve pressure from tank.

You can limp along with a leaking water heater by turning it on when hot water is needed.
For example a shower uses 5-9 gallons hot water.
Turn gas water heater on for 15-20 minutes.
Turn electric on for 20-30 minutes.

There should be a flip flop circuit in your heater that switches between the two heaters. I don't think they both heat at the same time. Check the rating on the indivitual heat element then compare that with the data printed on the heater RE: maximum WATT rating.

Now then, what did you miss - I'm thinking you missed the ohm reading. You measured 220 Volts but you did not check to see if the element is burned out or not. Move your meter to OHM and take a measurement with the power turned off. If the reading is "open" the element is buned out. If you get some reading beside 'open' the element is probably able to carry current.

Have you drained the sediment from your heater recently?

All the way up is a dangerous setting by the way. I suspect you know this.

My Reliance 606 40 gallon water heater only heats up enough hot water to fill a bathtub. We've drained it, the pilot light is fine, it heats up the water really hot, but it just doesn't seem to be able to...


How big is your bathtub? Is your water heater set on the hottest setting? What is the temperature of the hot water at the tap?

Keep in mind that hot water can cause severe burns. Children and those with diminished mental capacity can be seriously harmed by hot water.

The "40 Gallon" rating on the water heater is usually the amount of hot water the unit can produce in one hour. So the tank, and the amount of immediately available hot water, might be smaller than 40 gallons.

My bathtub is 2 feet wide by 1 foot deep and 4 feet long. This is 8 cubic feet or almost 60 gallons. So a 40 gallons of water at 120 degrees, mixed with 20 gallons of cold water (60 degrees), fills the tub with 100 degree water. My January cold water is 42 degrees, so it will take 40 gallons at 129 degrees to fill the tub. If the tub is cold to start it will take even hotter water.

So the water heater might be just fine.

Possible solutions:
1. turn the temperature up on your water heater- or the temperature control could be malfunctioning and not getting the water hot enough.
2. insulate your hot water pipes so that the water loses less heat on the way to the tub.
3. bigger water heater.
4. smaller bathtub, or less full bathtub.

sounds like the element is burned out....probably got turned on before it was completely full of water. You can get a kit that has new elements and upper and lower thermostat in it. Those are the only things that can go wrong with an electric water heater....other then leaks.

No water pressure in bath tub after turning off hot water heater


It could be back flowing into the hot water heater tank which is not full because of the leak. Even though the valve is closed on the cold water entry side, there is probably no valve on the exit side. That is how it is returning to the tank.
