My Rheem electric hot water heater occasionally leaks water then stops completely. This has done this three times now over the pact couple years.


It sounds like TP valve is releasing water, but you don't describe where water is located.
Run through process-of-elimination check list on following link:
http://waterheatertimer.org/Leaking-water-heater.html

1) If problem is TP valve, event could be caused by 'stacking'
Stacking is where you draw amounts of hot water many times in succession.
Top part of heater is plenty hot because water heater is keeping up with hot water draw.
Incoming cold water enters bottom of tank through dip tube causing thermostat to read cool temperature and activate burner or element. This causes higher than ordinary temperatures at upper part of tank and TP valve reacts by releasing water.

2) TP valve could be going bad.
http://waterheatertimer.org/How-to-replace-TP-valve.html

3) Improper venting can cause gas water heater to have water on top of tank or dripping down inside tank where it shows on floor after rusting out combustion chamber.

4) Thermostats are old or not reading correct temperature.
Turn down thermostats:
http://waterheatertimer.org/How-to-adjust-water-heater-temperature.html
Replace gas valve on gas water heater, and flush tank.

WATER IS DRIPPING FROM THE OUTLET VELVE LOCATED ON TOP WATER HEATER.


That sounds like the TP valve is leaking.
http://waterheatertimer.org/Water-heater-leaking.html

1) Leaking TP valve can be caused by defective TP valve
How to replace TP valve:
http://waterheatertimer.org/How-to-replace-TP-valve.html

2) TP valve can also be caused by overheated tank.
Turn down thermostat.
Install expansion tank on incoming cold water line.
Electric heater: thermostat or element may be bad and tank needs troubleshooting
Gas heater: thermostat is connected to gas valve and gas valve may need replacement.

3) First step is replace TP valve and see if that solves problem.

We have a brand new rheem 40 gal elec water heater, after installation we have water leaking from the base of the relief valve, pooling up in the plastic fitting and making it way over the side all over...


Water heater should be set in a drip pan.
Otherwise, put 1 gallon bucket under TP release pipe to catch water.
http://waterheatertimer.org/Water-at-bottom-of-water-heater.html#drip-pan

When you say relief valve, I assum you are talking about brass valve located on top of tank or near top of tank. This is TP valve and a pipe connects to this valve and runs down to within 6" of bottom of tank. TP valve has a small lever on it.
If you are talking about tank drain valve located at bottom of tank, then add a comment.
Following information is for TP valve.

Dripping TP valve can be caused by 3 different thing:

1) Obstruction inside TP valve. Open TP valve for a moment to flush away particles and slowly lower lever back down. See if water stops dripping, if not, then replace TP valve

2) Defective TP valve: replace TP valve. Turn off electricity to water heater. Let heater cool for several hours so you do not get scalded. Close shut off valve located above tank on cold side. Open tub spout to relieve pressure, open tank drain or open TP valve and empty water below TP valve level. If TP is located on top of tank, not much water has to be drained. Tank is under press when hot, so be careful. Put teflon tape on new valve and install with big pipe wrench by turning clockwise until TP valve is very tight.

3) Overheating tank. TP valve is temperature-pressure valve. If tank water is over 150 degrees, the TP valve starts drizzling hot water to relieve tank pressure.
Lower tank pressure two different ways:
a) turn down thermostat
http://waterheatertimer.org/How-to-adjust-water-heater-temperature.html
b) install expansion tank on incoming cold water line

I have a hot water heater that when running seems to build up an excessive amt of pressure. We just replaced the pressure valve because the old one started leaking when the hot water was running for any...


The most likely problem is that the thermostats are set too high. Remove the thermostat cover plates and look to see where the thermostats are set. The range should be between 120F and 135F. Liquids expand with heat so the higher the temp, the high the pressure. Decrease the setting on the thermostat until the leak stops.

The other likely cause is a head of air trapped in the top of the tank. After drawing hot water, it wiill be displaced by the incoming cold makeup water. This will compress any air in the top of the tank. As the water heats, the air will heat and pressure will build - possibly causing the leak. You can purge the tank of air by opening the pressure relief valve until water comes out (which I assume that you have already tried).

WHERE IS THE RESET BUTTON ON THE 6EM30-2 FROM AUG 2004?


Electric water heater has panels located on front of water heater.
Remove top cover, and insulation to reveal thermostat and element.

Stand on dry surface, including boards or plywood.
Do not hold screwdriver in mouth.
Do not touch any metal.
Red reset button is located on thermostat.
Push in reset.
If reset will not re-engage, then thermostat may be bad, or some other problem exists.
http://waterheatertimer.org/How-to-replace-thermostat-on-electric-water-heater.html
Screw terminals on thermostat are live.
When finished, insulation and cover must be put back over thermostat so thermostat not exposed to cool air that will cause thermostat to misread tank temperature.
Put ear against tank to hear bubbly-fizzing sound that says water heater is working.

If water heater is leaking or wet, do not touch unless circuit breaker is turned off.

Electric water heater is fully repairable by homeowner.
ECO red reset button trips when upper thermostat senses overheating.
You many have underlying problem if reset continues tripping:

I wrote a page on leaking water heaters.
With a checklist.
It sounds like you've done quite a bit already.
The element can leak around the gasket.
The TP valve can leak where it screws into side of tank.
Otherwise a leak on side of tank sounds like the tank is rusted through and needs to be replaced.
http://waterheatertimer.org/Water-heater-leaking.html

You should turn off electricity and water to the tank, and open tub valve on hot side to relieve pressure so the tank will not rupture.
Then you can limp along with a failed water heater by turning the water and electricity on only when hot water is needed.
This will buy you time until a new heater is installed.
A typical electric water heater produces 21 gallons of hot water per hour.
A shower uses 6-9 gallon of hot water, so heater only needs to be turned on 20-30 minutes for a shower, more if the incoming water is very cold.

To economize with your next heater, you might read the following two pages:

Relief valve on my water heater is dripping.Can I fix this?


There are two solutions:

1) Replace TP valve with same temperature/pressure as existing TP valve.
Buy the TP valve at hardware store or home center or plumbing supply.
Turn off water heater so water cools.
Hot water inside a tank is explosive ... so open the TP valve and test water temperature.
If TP is on top of tank, you don't need to drain much water before unscrewing
If TP is on side of tank, use the TP valve to drain water -or- use the drain valve
Unscrew TP to remove.
Put teflon tape on new valve threads so it will seal against leak.

2) If the new TP replacement starts doing the same thing, there may be a thermostat problem -or- thermostat is set too high.
If you keep the water temperature set high, you can add expansion tank to incoming cold water line.
Home Depot sells expansion tanks. Plumbing supply carries them,
The tank for residential water heaters is about same diameter as a football and it goes on cold water line.

My brand new 40 gallon water heater is leaking from the top temperature control. it is the first time it has bin filled. i have not had hot water in 3 days. please help.


Shut the water and power off. Connect a garden hose to the drain and open the valve as well as the t&pr valve to allow air flow. Remove the top element and inspect the gasket. It should be round without any wrinkels. Straighten the gasket if nessesary and reinstall the element.

If the water is leaking down from the top of the heater onto the thermostat, use a flashlight to inspect the connections on top of the tank, you may need to remove them and wrap them with teflon tape.

On rare occations, the machine that welds the tanks together will miss a small area. If there is no visable leak comming from any of the tank connections, you will have to tank the water heater back to the store and try another one. this is not what anyone wants to hear, but it does happen from time to time.

You can can the 1-800 number on the tank, but dealing with the store where you purchased the heater will be faster.
