I've tried everything possible to cure a hydrogen sulfide problem with my water heater, including replacing the anode with aluminum and strongly chlorinating the entire plumbing system several times.
The only thing that works is chlorinating the water periodically. I do this the only way that makes sense -- by removing the anode and pouring in about a cup of bleach.
This creates two problems. One, of course, is that the concentration of bleach will start off high and drop off gradually as the hot water is used up. So, initially, I'll have water that smells of bleach, and at the end of the period, the water will smell like hydrogen sulfide.
The other problem is that it's an annoyance to have to drain the tank a bit, pull the anode, pour in a measure of bleach, and reattach the anode. Sooner or later, those threads will die.
I've searched for an inline chlorinator, but every search engine combo I've tried pulls up swimming pool information. I can't find any chlorinator that's for a residential water heater (or residential system for that matter).
Any suggestions?
Thanks.
