Found water in cabinet of furnace. Would like to come back and re do the drain on furnace as it barely has any fall to drain properly. I Found a rusty screw in a drain line coming off inducer motor ( pics) . when system goes into second stage of heat it has hard time keeping up spitting/sputtering water out of elbow it is tied into. Could be done more effectively. Will put estimate to repair drain line if you choose to revisit this. But tonight I blew out the condensate line to restore full draining. and tested operation on furnace. Seemed to be working well and everything was within its parameters. Gas pressure 3.7 and flames looked good going into heat exchanger.
