There is no feature on a negative pressure system, therefore water is being sucked back into the system. System not level is running throughout the air handler and through the supply for them and fall through in the master closet Recommend to re-level unit completely added in blood to adding UV bacteria growth get all the water out and dispose of it replace supplies for them. Left disconnect unplugged so the unit would not turn on and condensate anymore. Explain to customer that we did leave the disconnect off and also took photo.
