You need to replace the aluminum anode with a zinc/aluminum alloy anode.
ANS 2 - If a hydrogen sulfide (or rotten egg) odour exists around your water, it's often an indicator of excess iron in the water supply. This can be bad for your Plumbing. I would advise taking a water sample(in a sterilised bottle) to a lab and have it analysed. If the iron content is very high you may well have to fit a softener or an iron filter.
BTW - changing the anode is an excellent idea anyway. Just may not be the solution.
Yes, hydrogen sulfide can react with aluminum to form aluminum sulfide. This reaction typically occurs when hydrogen sulfide gas comes into contact with aluminum metal, initiating a chemical reaction that produces aluminum sulfide and hydrogen gas.
Aluminum Sulfide
Al2S3 is aluminum sulfide, a chemical compound composed of aluminum and sulfur ions. It is a white or gray solid that is insoluble in water and can react with acids to release hydrogen sulfide gas. Aluminum sulfide is used in various industrial applications, including as a catalyst in organic synthesis reactions.
The chemical formula for aluminum sulfide is Al2S3.
hydrogen sulfide is not hazardous
Aluminum sulfide is insoluble in water, as it does not dissociate or dissolve when mixed with water.
The compound name for aluminum plus sulfur is aluminum sulfide.
Hydrogen sulfide is H2S and has no metals. Both hydrogen and sulphur are non metals.
The chemical formula for hydrogen sulfide is H2S.
The symbol for hydrogen sulfide is H2S.
The most often used name is "hydrogen sulfide". It could also properly be called "dihydrogen sulfide."
