Re: [Killietalk] Heating tanks

Rosario laCorte mentioned in his talk at the
Convention that he had a bad experience using the hot
water from his hot water heater to blend with cold for
filling tanks. He suspected heavy metals from the
sacrificial corrosion rods in the tank. I have stopped
using the hot water for most of my tanks since i heard
that. i also drained the sludge from the bottom of the
hot water heater.
Is this still a serious problem?
My understanding was that EPA has forced domestic water suppliers to
boost pH up to around 8 to stop corrosion from hot-water heaters, copper
pipes, and leaded solder joints in the latter.
Certainly, if your pH is much below 7, out of the tap, this could be a
big problem. [I recall killing a grow-out tank of FIL with lead plant
anchors when the pH was allowed to drift too low. Gruesome way to go!]
You are the chemist, here, Lee. Are there other problems with the
sacrificial rods I'm unaware of?
