Upon arrival customer showed me condensate line that exits furnace is leaking. Pulled on pvc 90 and it came right out of grommet. Cut off 90 to find adapter was installed backwards and short end cannot be clamped because it isn’t long enough. Used extra drain cpvc that was left over to connect to grommet, slid pipe in enough so it could be clamped, then used pvc 45 to connect to drain line. System isn’t leaking anymore but drain configuration isn’t right, we need correct fitting for pvc 90 to connect to furnace drain.
