Furnace repair. No heat call. Found water in the inducer motor. Resealed the inducer motor to the collection box. Repiped the flu pipe; didn’t have enough 2” pipe coming out of the unit before going to the 3” pipe. Also found that this unit has an old model of internal inducer elbow. Going to order a new style of elbow and would like to come back to install. The system is now operating properly with pressure-switched holding pressures and no water backtracking into the inducer motor.
