First of all disconnect the power at breaker panel or there should be a dedicated shut-off switch if this is a newer building. At any rate make sure its disconnected before you drain the water heater if power is on when the element is not safely submirged in water it will melt instantly. You can do this with a circuit tester after removing the access panel for the element. Turn off the water at the valve above your heater or at main and drain down below the eelement. Disconnect the wires attached to the element and remove element. This can be difficult without the right tool. The element just screws into the tank by way of a large thin nut welded around the element. You have to get a wrench or maybe channel locks or preferably a large deep socket on this nut and turn it counter-clockwise if your lucky this will work. But because the nut is so thin and in a tight area you might need to get an "element wrench" at home depot or where ever. There are different sizes measure your element first. Its basically just a deep socket made out of cheap steel with a hex outer shape so you can put it over the element nut and use a wrench or pliers.
Put your new elemeent in re-connect the wires, remember where they were connected when you take the element out.
Fill the water heater turn on power and replace cover.

I would also suggest try to tighten the existing elemnt first. If the leak is at the seal and not the element itself then the seal may be at fault and not the element.
Check your warranty, if this is less than a year old you should have unlimited warranty including labor. But I know that rheem simply does't have warranty contracts in place with repair techs in some areas.
If your warranty is unlimited (includes labor) and efective then hold them to it.

I have a Richmond 50 gallon on core water heater electric only have about five minutes for the hot water from do you were at the shows on the display bottom tank is at 58° how do you adjust the bottom part...

It appears that the water heater has 2 elements but on 1 thermostat, I would hope that there is an upper and lower thermostat . If water heater has just been installed the cold water feed is hooked to the hot water discharge, Cold water to cold hot to hat. They are marked on top of unit..Or the unit was powered up before tank was fully purged. If there is only 1 thermostat Shut power down and using a DMM check resistance on upper heating element and compare to lower. If the element is damaged it will show a high resistance. You can buy replacement elements, at box stores.

Not enough hot water

Some hot water means upper element is good, reset button is pushed in and not tripped, overheating is not issue, wires connected at top of tank are probably good, and unit getting power, but not necessarily full power. Otherwise we have not ruled out anything else.

Reliant 40 gallon tall electric water heater replaced both thermostats upper and lower elements flushed tank hot water very hot temp turned down lowest possible keeps tripping reset button what else could...

Problem has to be bad element or bad thermostat.

Test elements for short to ground through metal tank wall:
http://waterheatertimer.org/How-to-test-water-heater-element.html

Make sure factory-installed insulation and cover are re-installed over new thermostats so they do not misread tank temperature.
If problem does not show with elements, then replace thermostats again.

I have a 40 gallon rheem water heater for a mobil home that is leaking from the top.

If water heater is leaking, then open following 2 links to avoid tank rupture and troubleshoot leak:
http://waterheatertimer.org/Emergency-steps-for-leaking-water-heater.html
http://waterheatertimer.org/Water-heater-is-leaking.html

Open following link if you want to install your own gas water heater:
http://waterheatertimer.org/How-to-install-gas-water-heater.html

40 gallon electric heater at Lowes costs 207, and is easy do-it-yourself using same basic information shown in link above for installing gas heater, except less work.

To have gas water heater installed, can run $2-300 for installation plus cost of heater.
40 gallon natural gas water heater at Lowes starts at $300+, and tanks with longer warranty cost more and last longer.
Trailers require specific type of gas water heater, so be sure to request correct model.

If you maintain the tank: keep chemicals out of same room as gas water heater, attach bare copper ground wire between hot and cold pipes, flush tank each 6 months, clean gas burner each year as shown in manual, read the manual entirely for specific information about your model, and inspect/replace anode rod every 2-3 years then basic 6-year tank can last much longer.

It is leaking out of the top. not out of the hot or cold valves but out of a nut by the cold side.

Your tank is rusted out and needs to be replaced.
Link below is a troubleshoot for leaking water heater.
http://waterheatertimer.org/Leaking-water-heater.html

Protect yourself first:
If your tank is rusted, there is danger of rupture.
My friend welded his leaking tank, but he assumes the risk.
Ruptured tank can cause massive damage and water runs until it is shut off.

Hot water tank is under pressure because hot water expands and pushes against tank wall.
Turn off water to tank.
Turn off power supply:
Electric: turn off circuit breaker.
Gas: rotate knob to pilot so pilot stays lit but burner will not fire. To turn back on, rotate knob to ON.
Open hot side bathtub valve and relieve pressure on tank.

You can limp by with rusted tank by turning water heater on when hot water is needed.
Shower uses 5-9 gallons hot water
Bath uses 12-15 gallon hot water
Ordinary gas heater makes 41 gallons hot water per hour
Ordinary electric heater makes 20 gallons hot water per hour.

I buy water heaters at Lowes, Home Depot, Ace.
Look for scratch and dent models.
Buy drip pan for water heater.
Wrap electric heater totally with insulation except TP valve.
Buy new flexible connectors for water lines.
Offer 15% less than marked price on tank, because the store makes money on additional items.

> Most people can install their own electric heater since you just connect water pipes and electric wire, and it's done. Read link below since there are tips that help you buy and install electric.
> Generally people are nervous about installing gas water heater, so step-by-step instructions are shown on link below. Remember gas line is under less pressure than water line, so if you can install a water pipe, you can install gas line to water heater with crescent wrench, and soapy water to check for leaks.

We have a reliance 606 50 gallon electric water heater. recently we noticed it has an internal leak. I removed the top and removed some of the insulation. the pipe fittings are dry but when you put water...

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:

After connecting a drain line to the pressure relief valve of my MR85245 water heater, I now have water leaking badly out of the heating element door.

Turn off the electricity.
Turn off the water valve going into tank.
Open a bathtub spout to let hot water pressure off the tank.
Check top of tank for any leaks.
Open the top access panel and see if element is leaking.
Open bottom access panel and see if lower element is leaking.
The reduced pressure on the tank will slow the leak.

If element is the problem, you can squeak by for a while by turning on the hot water heater only when you need hot water.
Order the 'Marathon MR85245 replacement element' online
http://www.gpconservation.com/rheem/marathon-sp213670-titanium-4500w-lower-element
These elements may be available locally, but they are not the same as 'ordinary' tank-type electric heater elements that you buy at the hardware store.
Buy more than 1 element because the Marathon elements have problems.
One of the reported problems with marathon elements is the high price of stainless steel replacement elements.
Drain tank.
Replace element.

Was the tank full and all air out of lines before turning power onto it. If it's not full it will blow the new elements you just put in.


If the bottom one is good you get like luke warm then it will start cooling off.

If the top one is good it will be a burst of real hot then cold.
