Looking for some insight from some plumbers or someone who has dealt with them. Our water heater is I think 3 years old and last fall I noticed our hot water starting to smell like sulphur. So I researched and ended up putting in a new anode rod. Picked one up at Lowe’s. Drained the water heater and flushed it out be put the new rod in. First few days it was ok and now it’s back stronger than before. I’ve read where some take it out all together. Is there another style or type that will eliminate the smell? It’s only when the hot water is turned on. Found one online that is powered and runs some current through the water heater to help stop the bacteria from growing. I have an AO smith electric water heater. Thanks for any help or tips.
