@@justlead1 great video, found the product from a RU-vid advert above a search I did for installing the plastic vents. Much prefer the idea of this product on my project. Question: I understand you are a plumber and can do this, but would other plumbers usually do this or should I be asking another trade? If a plumber agrees to doing this, are there any qualifying questions I would ask to ensure they know what I am asking for and they know what they are doing? Many thanks.
