Thats what the j hook is for. The Op has something causing a negative draft in that room. So the cold air would be coming out of the bucket too.you can extend that pipe down and end it in a 5 gallon bucket (the kind you get at home depot) about 6 inches from the bottom of the bucket. this will make a cold air trap and the cold air will only come out when it is being drawn by and appliance
