Is hydrogen peroxide therapy affective

For a water heater? No. Hydrogen peroxide is oxygen bleach. It is much less effective than chlorine for sterilizing, but is great for oxidizing the liner of a water heater (rust corrosion). If you need to sterilize the inside of a water heater for some odd reason, you would be better served by using bleach, or just turning it on, and heating it up! (then discarding the tank full of hot water)

What affect does taking 35% food based hydrogen peroxide has ?

Don\'t drink it.

Small amounts used for mouth wash occasionally are okay when spit out.

Cleaning water heater with hydrogen peroxide is fine... because H2O2 is not poison outright.

harmless bacterial reacts with anode rod
anode protects tank from rusting
change anode, or remove anode, or treat tank regularly with hydrogen peroxide

I need to flush my Atwood L/P Gas water heater MPD 93756 I'm unable to locate where you add the vinegar. Can you advise!

Remove hot pipe connection, and flush out through drain valve.
Or remove TP valve and flush out through drain valve.
Connect small circulating pump to 5 gallon bucket with 2 gallons white vinegar like they do with tankless water heater, as shown following Bosch manual. And let run for 45 minutes.
White vinegar is safe for humans.

If odor is the problem, use H2O2 hydrogen peroxide, and not bleach. Hydrogen peroxide is safe for humans and easy to flush out of water heater and pipes. While it can take weeks to get rid of bleach, which is caustic and toxic.

I have whirpool hot water heater mmodleezf 40RDO45 V six months ago I had to buy and new anode and now the water is stinky again like rotten eggs, am I going to have to buy a new one every six months? ...

The smell is from bacteria.
1) The tank needs a new anode rod, but it also needs a periodic dose of hydrogen peroxide.
Recommend you reconfigure incoming water pipes where you can easily add 2 bottles of hydrogen peroxide and then flush water heater each 6 months. The peroxide kills the bacteria. Peroxide is not harmful to you since it is also used orally. You don't drink a bottle of peroxide, but it will not cause harm in trace amounts left in water heater.
2) There is something else to consider. If yours is a 12-year tank or lifetime tank, then you probably have 2 anode rods. Replacing one anode rod will not solve problem.
3) Another solution is a power anode rod. If your tank has two anode rods, then replace one with powered anode, and then remove the second anode rod.
According to the seller, he's had only one person where the water heater smell came back.

Here are links to information and to the powered anode rod:

Manufacturers are starting to add powered anode rods to their top models to assure longer tank life and better customer satisfaction.

Water smells like rotten eggs.

When the water heater smells bad, it is time for a new anode rod.
And then you flush the water heater with 2 bottles of hydrogen peroxide.

With water heaters that experience the problem frequently, you change your incoming cold water pipes so hydrogen peroxide can be added easily.,,20047047,00.html

About every two months the the hot water gets a sour smell. To get the smell out I turn both elements all the way up for 3 hours then drain the water heater, its good for about two months. The water heater...

The smell is from bacteria. The high temperature kills the bacteria. Some regions require water heater temp to be set at 135 because of bacteria.

A test to determine if only the water heater is causing problem: Turn off water to water heater. Smell water coming out of cold tap. Turn on water to heater, smell water from hot tap. If only hot tap smells, then water heater is suspect.

Another way to handle the problem long-term, is to reconfigure cold water pipes so you can regularly pour in 2 bottles of hydrogen peroxide during your flushing procedure. Pour in the hydrogen peroxide and let it work for a while. And then flush tank as you have been doing.

You should read up on anode rods also. Many people replace anode rods when tank begins to get odor.
