you know I looked into getting an RO whole house and the guy I was working with at the time said he didn't recommend doing that because the acidity of the RO water will start effecting the pipes.......
and I said "do i really want to be drinking it"
and he said "it is only trace minerals so you don't have to worry about it"
but I bought some pH strips and it takes a lot of those alkaline drops to bring the pH back up
