Complexity The reason so many 'amazing' idea never take off in houses and why cookie cutter housing rules. There are big regulations, if you cross the piping you could theoretically contaminate the streets or larger water supply. You now have two water systems in a house. Plumbing is not cheap, having two is more $. You'll need a pump and holding tank, a place to run the pump and holding tank. It'll might me loud and can break down, will fail in blackouts. Can the tank get legionnaires disease?
