Review on 🔧 Enhanced American Standard Vormax Silicone Seal, 2-Inch by Patrick Cooney

This American standard toilet tank drainage design (4370A) has to be the most complicated and least thought out. It has 2 drains and 2 dampers! The number of parts has been doubled! What were they thinking and how was this design approved and put into production? The toilet is only about 2 years old. I have 2 Kohler toilets in my house that are 10 years old and have never broken a single part. 2 silicone Vormax valve seals "seem" to eliminate slow leakage. If they fail again - after 2 months or 2 years this toilet will cease to exist and Kohler will be installed. Don't buy a toilet that has more than one drain and valve.
