    Is it close to any pipes that come out of the top of heater

  • dkinney541 Jan 02, 2011

    approx 5" from top valve

  • dkinney541 Jan 07, 2011

    Thanks for your comments, I have had the tank replaced. Repair was not a viable option, according to the two local plumbers who came out to look and one I talked to via phone.

    As you have indicated, the pro's have determined the same as your comments, I have replaced the tank.

If water heater has a hole, then water heater is rusted out and must be replaced.

Immediate problem is ruptured tank.
Water heaters are under pressure, and rusted water heaters rupture and water runs until water is shut off.
This causes major damage inside home.

Protect yourself first, and then let's talk more.
1) Turn off water at shut off located on cold water line above tank.
2) Turn off power to water heater:
Gas heater, rotate valve to 'pilot' so pilot is lit but burner does not turn ON.
Electric heater, turn off circuit breaker.
3) Open tub spout on hot side and let run a bit to relieve pressure.
4) Now your property is safe.

You can limp along with failed heater if leak is slow.
Turn heater ON when you need hot water.
Typical Gas heater makes 41 gallons hot water per hour.
Typical Electric heater makes 21 gallons hot water.
Shower uses 5-9 gallons hot water, bath uses 12-14 gallons hot water.

If you are going to install heater yourself:
Look at label on side of old tank to identify size and particulars.
I buy ordinary heaters from Lowes and Home Depot and always look at scratch-n-dent models.
Buy same size heater if it worked fine before.
Buy new flexible water connectors.
Set water heater in drip pan.
Offer 10% less than price shown.

#1 rule) tankless heaters are a rich-man's toy, because tankless will never pay you back, and will become major money pit with 1 repair.
2) How to install gas heater:
3) How to install electric heater:
Read link above because many of same steps apply to electric.
The difference with electric, is turn off power, disconnect wires, and reconnect wires exactly like before. Set electric heater directly on insulated surface like dense blue styrafoam. Cut styrafoam in a circle so it fits inside dip pan.

    Thanks Gino,

    I guess I forgot some info - my hot water tank is an Armitrol WH-7P boilermate which is linked to my boiler or furnace. I am thinking all of the info and comments you provided for the electric and or gas hot water heaters may still apply, but thought the additional info might promote a different answer, thanks for your time.

  • dkinney541 Jan 02, 2011

    I have protected the unit by turning off the cold water intake which appears to pressurize the tank, i have also prevented the flow from the unit so the heating coil did not burn out. I think the unit somehow goes back through the boiler and have not turned it off, but have shut down the boiler because i an not sure how the system works, glad iys not too cold today!

    I am not an indirect water heater expert. When heater is connected boiler, then it is called indirect water heater. There are similarities, and differences, between indirect and 'regular' water heaters. One similarity is that your heater has a hole. Your tank is rusted-out and it can rupture. I have a friend who welded his rusted water heater and got more life out of the tank., but he assumes the risk. As general rule, a rusted tank needs replacement to prevent rupture and water damage. I am going to suggest you get follow-up opinion from the professional plumbers at the Tank. Ask them if there is a way to limp along with indirect heater until you get it replaced. If I miss your post on the Tank, let me know what they say:

What would be the cause/s if the water heater was to overheat?

THERMOSTAT, inside or underneath the temperature control.
If the heater does overheat, the temperature/ pressure valve on the side of the heater will leak or spew water. This is so that the water heater does not explode. It is far more common for the valve itself to go bad.than the thermostat. The temperature/ pressure valve is a common replacement part. The thermostat is not available as a replacement part on most tanks.

How do I Remove Magnesium Anode ?

The following page has instructions and a link to a video:

How to:
Rods are installed in top of tank.
Most are located under a 2" round plastic cover located on top of tank.
Some anode rods are connected to hot water nipple
Read owner's manual to see location of anode rod
See list of water heater manufacturers and brands to find product manual.
Before starting, turn off heater source: electric water heater: turn off circuit breaker; gas water heater move control knob to pilot.
Close shutoff valve on cold water side of water heater
Open bathtub faucet to relieve pressure and let air into water line.
Open drain valve near bottom of tank,, and drain 2 gallons of water.

Use 1-1/16" socket for hex head rod
Rod will be rusted in place, use generous amount WD-40
WD-40 spray is flammable and will burn so be careful around heat source.
Loosening rod: go slow and check that water does not seep up when loosening rod because hot water can spew out hole if tank is very hot ... it is important to drain enough water out of tank to avoid accidental scalding.

Install new anode rod: One source says/ use pipe compound on thread instead of teflon tape. Other sources say use teflon tape. Either way, tank metal and anode metal must meet, so rod will work.

Hot water is running very slow

Definitely calcium is your problem. If you want to work on this your self turn off the power and drain the tank into a bucket, you will find lots of calcium in the tank. Rinse it out a couple times with fresh water, and vinegar.
