Do I need this if I have an existing dryer vent?
I'm buying a replacement dryer. Do I just attached the exising or do I need a new one?
Always worth getting a new vent. Most vents collect debris, and if there is a build up of heavy lint, fire can become an issue. Smart to start with a new vent whenever you get a new dryer. Well worth the cost. We had ours professionally installed too. Also worth the price for us as our spacecwas tight behind our dryer.
