Review on 🔧 Enhanced Air Admittance Valve Trap Assembly Kit: Tuuber Vent & Superior Seal Air Admittance Valve Combo by Clint Fick

I've been using this product for a week now and I still don't know if I want to return it or not. Installation was a breeze. Each piece fits and was easy to set up with my sink. The problem that made me give only 3 stars is that the water flow is not as good as advertised by this product. I don't see any water in the sink, but it doesn't drain right away. I suspect that the vacuum in my lines plays a role. Another thing is that this tool is below the level of the sink, so it is more difficult to do its job. Maybe try installing some flexible tubing and hook it up to the kit (remove the AAB part) and hoist it over the sink to see if the water flow changes.
