Causes for rusted/ failed tank: Gas and electric:
Is tank 6-12 years old? Yes = high risk of rust.

Has anode rod been checked and replaced regularly? No = high risk of rust.
House has water softener? Yes = high risk of rust.
                Read about anode rods and affect of softened water.
Tank flushed regularly to avoid build-up inside? No = high risk of rust.
             See how to clean and flush tank.
Water pressure over 80 psi? Yes = high risk of rust.
             How to check water pressure
Other water heaters have failed at same location? Yes = high risk of rust.
Electrically bond water pipes together, and ground tank. Bond means connect hot and cold pipes with ground wire. Make sure main electric panel is grounded to ground rod  and not to water pipes. Scroll down page to see example image of bonding.

Water heater leaking
Water bubbling up

Tank must be replaced

Emergency steps for leaking water heater
Water bubbling up from top: Steel tank rusted:
There is steel tank located under the exterior shell of water heater
Inner steel tank can be seriously rusted and all that shows is water at bottom of tank or bubbling up at top of tank.
Anode rod prevents tank from rusting.
Inspect and replace anode each 1-3 years and prevent rusted tank.

How to maintain new water heater

1) Large leak: How to turn off water heater and drain tank
2) Small leak: Turn off water heater, Turn on tank only when you need hot water.
This will give time to shop and replace tank.
If nipples are leaking, then remove and put 6 wraps teflon tape and it might seal, but tank will probably fail soon.

More bills Do you need to replace heater right now??
"It is possible to limp along with a failed water heater if the leak is slow and if you turn off power and water when not using hot water. A hot tap needs to be left open also to prevent pressure build-up in tank. This trick could buy you some time, possibly up to 3 months. With time, you can consider how to make the system do more for less as well as comparison shop, get competitive bids, etc" Forum

Glass lined steel water heater Prevent & stop rusting:
If tank is already rusted and leaking, then replace tank.
Steel water heater tanks are made from enamel-coated steel that is called 'glass lined.'  This technique was created by Rheem in the 1950s and replaced prior water heater technology, some which lasted longer than modern tanks, but much more expensive.
Once anode rod is depleted, water quickly rusts tank.
Enamel coating does not stop rusting.
Eventually tank develops pin holes and water starts seeping.

Rusty brown water Rusty hot water
Rusty hot water at faucet or drain valve means galvanized water pipes have rusted, or water heater heater anode rod is depleted and tank is rusted
1) Inspect tank immediately for leaking.
tanks should be inspected each 6 months.
2) Replace anode rod and flush tank

4) Rusty cold and hot water mean that water heater is probably not causing rust. Rusty cold and hot water can be caused by deteriorated galvanized pipes and/or water well tank, and also city water pipes, or incoming pipe between water meter and home. Check which outdoor tap is located nearest to water meter, and see if water is rusty ... this will say if problem is inside outside home.

Applies to Gas water heaters
Some dripping is common.
A lot of water can mean missing vent cap on roof
Can also indicate improper venting
Improper vent can cause water drip down flue, and sooting on top of heater indicate risk of carbon monoxide poisoning.

Carbon monoxide CO is odorless deadly gas.
Burning hydrocarbon fuel releases carbon monoxide. And other by-products.

Symptoms: Family gets headaches and sleepy when inside home, and headache goes away after leaving home.

Deadly condition: Family goes to sleep never wakes up

What to do/ first aid: Remove people immediately from home and lay on side.
Do not lay on back, or person will suffocate/ die.
Call 911 for medical emergency.
Open windows and doors.
Call plumber to locate source of CO gas

New Gas water heater: Normal to have dripping water at startup that stops when tank fully heated
'First time a gas water heater starts up, it will produce condensation. You may hear dripping and see small puddle. Once heater warms up, the problem disappears.' 'Condensation can also be caused by heavy water draw and very cold inlet water temperature.' Condensation is temporary and stops when water gets warm.
If leak continues after water heater warms up, then check vent pipe for dripping condensate. If vent pipe is dry, then water heater is rusted out and needs replacement.

Flue pipe safety
Larger image

During typical water heater combustion, hydrogen content of fuel is burned and the result is hot gases. One of these hot gases is steam or water vapor. Adequate venting or air draw up vent is required so gases vent outside. 
When there is inadequate draw, the water vapor cools and condenses on inside wall of vent pipe. This condensation water is acidic (pH 3-5) and corrosive. It will corrode steel metals and other materials.
Improper venting causes water to drip down vent into combustion chamber of gas water heater. Parts inside combustion chamber rust. Holes develop in bottom of water heater. Inspect combustion chamber for rust and water.

If steel vent pipe is not venting, the vent pipe will rust and get holes, or joints will fall apart. This situation causes hot gases to enter home and poses serious risk of odorless CO poisoning.
Flue Pipe Safety

Rusted flue pipe -or-water on top of gas water heater could indicate serious problem.
Call a plumber if you are uncertain.
Check pipes and flexible connectors for leaks.

If water coming from flue pipe:
1. Vent cover could be missing > rain water entering flue (replace cover)

2. Flue pipe clogged with bird nest or come apart or damp from improper venting: danger of odorless Carbon Monoxide poisoning

Serious danger from CO poisoning, a plumber should be called if you are uncertain about vent pipe water leak

"Excessive corrosion of vents, burners, or heat exchangers, is caused by contamination of the supply air.  It turns out that traces of chlorine bleach vapors from clothes dryer vents can do considerable damage when ingested by a burner and then deposited with condensation onto metal surfaces such as vents, etc." Read troubleshooting at forum

Protect gas water heater parts. Do not install cold water line above gas valve where condensation drips on valve. Annually clean burner area with wire brush and vacuum cleaner. Read Remove chemicals from same room as water heater. Chemicals corrode water heater parts. 'Spray propellants, cleaning solvents, refrigerants, swimming pool chemicals, calcium and sodium chloride, household bleach, waxes and process chemicals are corrosive at very low levels with no odor."
Test water heater vent How to test water heater vent.
Let main burner operate for 5 minutes.
Then put match near vent hood.
Smoke from match should get sucked into vent and draw upwards.
Repeat same test with all household vents turned ON, such as kitchen range hood and bath vent fans.
