I have read many entries on the boards regarding replacing/removing anode rods but I wonder if this is my problem. I have a culligan softner and a whole house filter (both have new minerals and filters)and am experiencing the rotten egg smell in my hot water only. The culligan people said the smell in the hot water only indicates a bad a. rod. I told them my tank is only two months old and is an expensive model and they replied it is more likely to occur in a new tank. We have well water. One more thing, I noticed a small piece of pipe comimg off of our holding tank is corroding. It is not copper but connects to a copper pipe going in to our softner. Could this be the potential problem? Perhaps contaminating something or causing a reaction. Please help!! I can’t stand the smell!!
Occasionally, a hot water heater is a source of hydrogen sulfide odor. The magnesium corrosion control rod present in many hot water heaters can chemically reduce naturally occurring sulfates to hydrogen sulfide. Pleas visit this site it contains more infomation. http://www.ianr.unl.edu/PUBS/water/g1275.htm
Have you removed the magnesium corrosion control rod from your water heater?
If removing the rod from the heater does not get rid of the odor I would suggest getting your water tested to find out if you have a H2S problem in your well.
Oh and remove that piece of galvanised pipe connecting your well tank, change it to a schedule 80 pipe nipple. It is not the source of your odor but it is a galvanic cell. This is when dissimilar metals are in contact with each other and with conductive water, generates electricity. The flow of electrons created by such a cell accelerates the corrosion of iron in contact with copper or brass, for example, by stimulating the flow of electrons away from the iron.
