Thanks, Rob. I'm hoping we'll be ok there.
While we were diagnosing the odor problem with the hot water about a month or so ago, my plumber drained the water heater, and cleaned out all the scale at the bottom. Then we cleaned the heater with hydrogen peroxide--poured a quart of peroxide in the anode rod socket, filled the tank, let it sit four hours, then drained and refilled.
About ten days later, after we found out about the bacteria levels, we shocked our well and made sure both hot and cold lines in the house had chlorinated water all the way through, then left it sit for 12 hours.
Finally, after installing the treatment system yesterday, the installer did another chlorine shock of both hot and cold lines, and the water heater.
The water heater should be the cleanest part of the system now.
Do you think that's enough? I'd be glad to hear any additional thoughts.
