not sure if it is a high eff one or not. It isnt hooked to my main
water comming into the house at all.

I dont think this much water could be comming out of this unit. It
doesnt make any sense.

If installed properly, the condensate drain will also handle any
condensation or rain water in the furnace vent. Just install a new hose and
see if that solves the problem. Check if the furnace vent pipes terminate in
a horizontal or downward direction.
