Water leaking from the base of the tank - Rheem 40 Gallon FVR NATGAS Low WATER HEATER 6YR 22V40SF

The page linked to below has a checklist of causes for gas and electric water heaters.

Some high points to look for:
Are the pipes on top of heater dry?
Is the vent pipe clean and new-looking or is it discolored?
Improper vent pipe causes condensation that can drip down and rust out the combustion chamber.
Is the TP overflow pipe dry, or has it been releasing water?
Is the drain valve leaking?

Tank could be rusted and ready to fail:
Here are the red flags
Water heater is older than 6 years.
The heater has never been flushed to remove sediment.
The amount of hot water has decreased ... tank can fail even amount of hot water is the same.
House has a water softener and anode rod inside tank has not been checked or replaced.

If you feel your tank is rusted and ready to fail, it is important to reduce the pressure inside the tank until you can get tank replaced.
To do this, turn the thermostat to vacation.
Turn off the water valve above the tank.
Open a bathtub spigot on the hot side.
Keep thermostat on vacation setting except when you need hot water.
Keeping the pressure down by removing the heat source will let you 'limp along' until you have the time/money to purchase a new water heater.
Keep in mind a tank failure will flood the surrounding area, and the water will run until it is shut off.
It is very important to keep the water shut off to a tank in this condition, except for short periods when you need hot water.

Hot water strategy for limp-along:
Typical rule-of-thumb, a new gas heater produces 41 gallons of hot water per hour. There are tanks that produce a lot more depending on recovery and first-hour ratings.
A bath uses 10-13 gallons hot water, a shower uses 6-9 gallons hot water.
So your limp-along water heater can be turned on for brief periods of time and still provide hot water.

If you want to economize your water heater, or are looking for savings-factors to consider when buying next water heater, read the following:

I seem to have a leak at the rim of my water heater where the screws attach to the cover, can this be fixed or do I need to replace it?

Water heaters are sealed tanks. The only places where water would normally be able to leak would be:
  1. Water inlet
  2. Water Outlet
  3. Heating elements
  4. pressure release valve
  5. drain valve
Leaking at the base is indicative of a rusted-out tank. But before you trash the old one, secure power and remove the side covers where the heating elements are installed to verify they are not leaking. If they are OK, the unit probably needs replacing. And even more likely if the unit is more than 10-12 years old. Don't delay on this as leaks from rusty tanks can blow out and cause serious water damage,

Usually, this means that the water tank is leaking. It is not worthwhile to fix the leakage unless you have welding equipment. Just buy a new one.

I own a house with an electric GE hot water heater. 8ESOT12AA01 Serial # 090122 5750 I do not know how old the hot water heater is and advice about when it should be replaced. No leaks to date but I...

GE is made by Rheem, but the market is always changing. Rheem-based serial number shows tank was made in 1990.
Tank will last as long as anode rod(s) protects steel tank from rusting.
If your tank has two anode rods, then tanks lasts longer.
That's how companies determine if water heater is '6-year' or '12-year.'
I don't have manual for your product to say if you have 12 year tank. Side of tank might have information blurb besides mandatory label that shows serial number.
You can update your water heater by replacing anode rod(s) assuming they can be loosened and removed after this number of years, which is a big IF with old heaters. Your plumber might have impact wrench he uses to see if anode can come out.

If the water heater is making gurgling rumbling and/or crackling sounds then tank has sediment build-up.
You can also get a baseline of rust by flushing tank and watching if water is very rusty.

If you flush tank regularly, and inspect anode every 1-3 years, a tank will last many years longer than manufacturer's label.

Is my water heater still under warranty leaking water on top of heater and out from bottom and from plate

1) If water heater is leaking, I suggest you protect yourself first.

2) You have to do some work to find out if tank is under warranty.
-Contact manufacturer:
-Contact installer: If plumber installed heater, then installer backs warranty for some manufacturers. If you installed heater, then warranty is less or void
-Look at paperwork and manual that came with water heater and read about warranty coverage
-Look at markings on tank to see if tank is 6 year, 15 year etc
-Warranty is based on date of manufacture: To find date of water heater, look at serial number located on label on side of tank:
Open link below for serial number decoder by manufacturer.

3) If tank is older than 6 years, and tank label shows this is a 6-year tank, then tank is no longer under warranty.
If you have a lifetime tank, then warranty is in effect, so contact manufacturer.

Open following link to see troubleshoot checklist for leaking water heater:

Other things to consider:
-If tank rusted out after a few years and installer did not install a jumper wire between hot and cold pipes, then tank warranty will probably not cover tank.
-If tank rusted out and you have water softener, and did not inspect anode rod or maintain water heater, then you did not read manual or maintain heater, and warranty might not cover problem.
-I suggest you read water heater manual cover to cover so water heater will not start leaking.
