DSC_2815.jpg - Soon, the Zone 9 circulator pump's blue power light came on and the pump rumbled to a start. Still, no heat was getting upstairs. Nuts! I suspect that Zone 9 may have been nonfunctional for at least a year. The zone plumbing had so much air and sediment in it that the pump could not push the hot water to the attic air handler. I flushed the Zone 9 plumbing sludge out and now, everything works. There is heat in the 2nd floor bedrooms.
