That keeps getting re-posted every few years.

Yes, it CAN be a problem, and it CAN happen, but those are the same photos I keep seeing. SO it does not happen very often at all ... but it CAN.

An excerpt from "Pofessional Home Inspection Results" by Richard L. Burgess and Phillip Stojanik...

-quote- In properties which have not been occupied for any length of time, including new construction, the "rotten egg" smell of hydrogen sulfide may accompany the water supply. This is the result of a chemical reaction associated with the magnesium in the sacrificial anode(s) installed within the water heating equipment. When this odor is strong, it is recommended that inspectors do not operate the dishwasher unless it has been flushed. The buildup of hydrogen sulfide can cause explosion of the dishwasher when the electric heating element is cycled on. This is a rare occurrence, but one which can be averted by an alert and knowledgeable inspector. -unquote-

These only occur on military bases. It's called an IED- Improvised Exploding Dishwasher

Not a Myth http://www.geappliances.com/search/fast/infobase/10000959.htm

Hydrogen Gas Build-Up

Hydrogen Gas is produced by the chemical action within your water heater. The gas can accumulate in the water heater and/or water pipes if hot water has not been used for a period of two weeks or longer.

Caution: Hydrogen gas can be explosive under these circumstances. To prevent the possibility of damage or injury, if you have not used hot water for two weeks or more, or move into a residence in which the hot water system may not have been used for some time, turn on all hot water faucets and allow them to run several minutes before using any electrical appliances which are connected to the hot water system. This will allow any hydrogen gas to escape.

Caution: Since the gas is flammable, do not smoke, use an open flame, or appliance during this process.

If the water heater is turned OFF, the build up of gas would be eliminated.

Hi gang,

Silly question, but does this apply to all types of water heaters. Ie. electrical, gas, etc or only certain kinds. Or is it a gas that builds up within the tank itself for some reason?

Your thoughts and comments are appreciated

Thank you,

It is a chemical reaction inside the water tank between the water and the sacrificial anode.

Don't matter the type, gas electric, etc.

It it's hot water and there's a sacrificial anode, you'll get the hydrogen sulfide buildup.

You'll know it if you have it. Run the hot water at the kitchen sink. If it stinks, you've got hydrogen sulfide and you need to get it flushed out before exposing a heat source, such as the heated dry element in the dishwasher.

Just let the hot water run, at all points, but especially the highest point until the stink is gone.

I've ran into the stink a time or two, but don't know of anyone's cousin it actually happened to.
