Furnace in attic without float switch, would need to add switch to prevent further water damage in ceiling. Vent draft hood connector needs to be added to vent pipe due to it not being secured & possibly leaking carbon monoxide into the attic. Float switch installed along with draft hood for vent pipe. When fixing the drain, lifted the drain pan slightly & the bottom cracked out & would need to replace drain pan as well. Drain is working properly now but will have to come back to replace drain pan. No other issues to report.
