Upon arrival both primary and secondary drain lines were clogged and the aux pan was full of water after preforming a lvl2 drain line clear weeks ago. The aux pan was also holding water as well and float switch was not triggered because of the position in the pan. I moved the float switch in proper position and also preformed a major lvl3 drain line clear. The lvl 3 drain clear included clearing both drain lines at the furnace and in the bathroom sink. I found a abundance of rust from the old pan. Drains are clear and draining properly at this time.
