SLIPPING DUCT HOSES ON DRYERS
Only use metal screw type clamps on flexible ducting. In some tight installations when you have a short run flexible ducting is sometimes the best thing to use. But follow the installation instructions carefully, never use over 8' of flexible tubing for example. Rigid metal pipe is differently best for long runs, but it will actually accumulate more lint inside than plastic ducting in many cases. This is because the heavy metal pipe gets more condensation inside it which collects lint. I have cleaned and worked on or installed at least 10,000 dryer vent systems so far and still going.
