Sulphur odor from the domestic hot water only not the cold, how

Sulphur odor from the domestic hot water only, not the cold. How come? What can be done to get it out?

Ken_8

The problem is simple...

The zinc (or aluminum) sacrificail anode inside the heater is "toast" and dissolving in a "last gasp" attempt to reduce ionization (call it rust) from occurring inside the water heater.

A trace scent can occur when the anode is almost all used up.

If the rod is not totally spent (sounds like it's very close) you can get a replacement anode.

I urge you to get one and install it before the water heater self destructs. Flush all the junk out of the bottom drain and rinse throroughly to remove whatever traces of the crumbled "rod" may be left inside.

Let us know how you make out. You'll know all you need to - when you see what the new anode and old one you remove look like in comparison!

Anode rods

When you go to get the replacement anode rod, make sure you get the one with the correct composition for your water system. Ask your supplier. They should be able to help you.

anodes

Hello: My understanding of things agrees that the anode is largely the culprit. It produces hydrogen gas as a byproduct of protecting the tank. This gas is "food" to anerobic bacteria in the water. The bacteria in turn create the rotten egg odor. Magnesium and aluminum anodes are commonly used. There is a special anode for odor that has about 8% zinc, in aluminum. So, to fix: Flush the tank. Add 3%hydrogen peroxide, (one to two pints per 40 gallons) and put that zinc/aluminum anode in. Peroxide is simply highly oxygenated water. That extra oxygen kills off the bacteria in a way nontoxic to us, so there is no need to flush the tank after treating it. Hope that helps.

Underwear weith Activated Carbon

Scott, recently saw an ad for dog underwear with activated carbon that reduces or eliminates odor from dog farts. Should be adaptable to your needs. Could there be a better example of technology meeting the need?
