No water coming out of drian on rheem upflow 90% furnace.
It shuts the unit down cause it won't drain. I cut the drain line on the outside of the furnace below the condensate trap, and no water came out, and the drain is clear to the sump pit.
Water is backing up into the furnace, Only when I remove the bottom vacum line and suck the water out ( about 3 cups) every few hours, Then the furnace will run.
Any ideas? Thanks
