8 Feet Is A Long Run...

For a flex tube. You may want to shorten the tube to about 4 feet but keep it aimed in the general direction of the roof vent. Yes, make sure you have no low spots in the tube. The problem is that the flex tubing acts as a condensing tube for the warm, moist air. Again, make sure that the flapper valve on the outlet of the fan is working. If it is stuck open, warm air will rise into the tube like a chimney. As long as the fan motor assembly isn't wet, it should be safe to start it and let it run to dry things out. Letting the fan run after taking a shower is a good idea, it will limit the moisture buildup in the house if that is a problem.
Lastly, installing an insulated vent tube in place of the flex tube may also help.
Good Luck!
