If the water heater is working fine than I would not worry about the function of the water heater. What the problem may be is that some of your WATER LINES HAVE MOVED, AS THEY WERE NOT SECURED PROPERLY. The sound you may have heard was the Copper or PVC(Plastic) lines just getting back comfortable. I Suggest checking that your water lines are secured about every 3 or 4 feet with the proper ancjhor....Metal for metal pipe, copper for copper pipe, etc. Sometime as in my house, pipes are run through a hole drilled through a stud or a piece of wood, usually when hot water is run through this pipe. You can here an expansion of the water line interacting with the pipe expanding, if the hole in the wood was not drilled big enough......Experience of remodeling a very old house.......Joe

SOURCE: My Rheem hot water heater stopped putting out hot

If you are not familiar with the element, I would get someone that is familiar with one and have them do it. It's not something I would recommend you do based on your question. There's electrical, pressurized water tank, and a whole lot of water that may cause you to have a worse bad day.

SOURCE: Not heating water hot enough or as much water.

You probably have a bad heating element. Probably the upper element.

Disconnected condensation drain on hot water heater.


Tankless or hybrid water heater?

Tankless gas must have special fitting between water heater and vent that has a condensate line fitting. Hot toxic vent gasses traveling up vent pipe cause acidic water vapor to form inside vent pipe that drips back down vent and drips onto heat exchanger and other parts eventually burning hole through expensive metal alloy heat exchanger, rendering tankless computer water heater useless after electric circuitry gets wet and shorts out.
http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html#vent

Hybrid or heat pump type computer water heaters must have condensate drain connected to catch pan located just above storage tank and below compressor. Condensation can form on condenser coils and drip into catch pan where there is primary and secondary drain

Can I run the hot water heater with a generator


Yes.
Ordinary electric water heater can run on any voltage from any direction (excluding volt/amp ratings below what can heat element coil).

Voltages include single-phase, split phase, and 3-phase residential/commercial voltages with either 50 or 60 Hz.
http://waterheatertimer.org/How-to-wire-water-heater-for-120-Volt.html
http://waterheatertimer.org/How-to-wire-water-heater-thermostats.html#3-phase

Install line fuse.
30 amp fuse would be required to prevent wires from overheating, and eliminate fire hazard.

This information does NOT apply to energy-smart electric water heater with box on top of heater, or newer energy smart with electronics, or to hybrid water heaters, or heat pump water heaters with delicate electronic circuitry.

Why it works like this:
Ordinary electric water heater thermostats are mechanical bi-metal switches and respond to tank temperature, and are not operated by electricity.
Ordinary generic elecrtic water heater thermostats switch electricity on-off using mechanical bi-metal switch.
Heat elements are simple coil of thermal wire that gets hot when voltage is applied.
The element will get hot when power is applied.

Why is my Rheem water heater making a "hissing" noise?


It is boiling the water. Turn it down. Look on the side and remove the small cover to expose the thermostat Turn it counter clock wise to reduce heated water temp.
There may be two.
After an hour or so test the hot water and see if you can keep your hand in the flow of all hot water. If it
is so hot it will burn you it is still too hot. 170 is hot enough. That is slightly painful and will cook the skin

Rheem 49 gal model 81V400B - hot water lasting only 5-10 minutes then takes an hour to heat back up.


Ordinary tank-type electric water heaters are fully repairable by homeowner.

A) Basic info on Rheem
Rheem electric water heater website:
http://www.rheem.com/products/tank_water_heaters/electric_water_heaters/
Find age of Rheem: look 2nd and 3rd digit of serial number, for example 06 is 2006

B) Water heater has some hot water.
That says certain things: upper element is working, water heater electricity is working, reset button is not tripped, and heater is not experiencing run-away overheating event.
http://waterheatertimer.org/How-it-works.html

C) That leaves 4 suspects that cause lower amount of hot water.

1) TP valve is running hot water out of tank -or- leaking faucet is running hot water out of tank.
Check for leaks
http://waterheatertimer.org/How-to-replace-TP-valve.html

2) Lower element is burned out.
Test lower element using inexpensive multi-meter from Home Depot.
http://waterheatertimer.org/How-to-test-water-heater-element.html
Replace element with same wattage shown on label, and clean out sediment:
http://waterheatertimer.org/How-to-clean-sediment-out-of-electric-water-heater.html
http://waterheatertimer.org/Clean-sediment-out-of-water-heater.html

2) Upper or lower thermostat is bad.
Replace both thermostats for about $25.
http://waterheatertimer.org/How-to-replace-thermostat-on-electric-water-heater.html

3) Burned or shorted wire located between upper and lower sections of tank.
Turn off power. Open covers on side of tank. Remove insulation. Inspect parts for signs of high heat and burning. Especially check lower element. Tighten any loose wires. Replace part that shows signs of burning.
Put insulation and cover back over thermostats so cooler outside temperature doesn't cause thermostat to misread tank temperature.

I am only receiving half of the normal amount of hot water.


You have electric water heater.
Electric water heaters are fully repairable by homeowner, excluding hybrid type.

Rheem electric water heaters:
http://www.rheem.com/products/tank_water_heaters/electric_water_heaters/
Rheem fury series manuals and models
http://www.rheem.com/product.aspx?id=09DF2BDD-5E11-4D32-B574-84ACFB8A4619

Age of Rheem water heater is shown first 4 digits of serial number located on side of tank: for example 0705 means July 2005.
Serial number also shows model number & wattage of elements in case you need to buy new generic 4-bolt type 4500 Watt element from hardware store.

A) If your water heater receives very cold incoming water, it may not heat fast enough to keep tank warm.
Add a tempering tank.
http://waterheatertimer.org/Tempering-tank.html
Add insulation over entire water heater except TP valve. Insulate pipes completely.
Read more information:
http://waterheatertimer.org/9-ways-to-save-with-water-heater.html

B) 40 or 50 gallon water heater is 240Volts and tank will have 2 access panels on front.
Rheem ships all water heaters with 4500 Watt elements.

Narrow down the suspects:
C) Water heater has some hot water.
This tells us upper element is working.
And that water heater electricity is working.
And that reset button is not tripped.
And that heater is not experiencing run-away overheating event.

That gives us 3 solid suspects.
1) lower element is burned out. Test lower element using inexpensive multi-meter from Home Depot.
http://waterheatertimer.org/How-to-test-water-heater-element.html
Replace element with same wattage shown on label, and clean out sediment:
This will restore water heater to full 99% efficiency.
http://waterheatertimer.org/How-to-clean-sediment-out-of-electric-water-heater.html

2) Upper or lower thermostat is bad. Replace both thermostats for about $25.

If you want to test thermostats and all parts before replacing anything:
