I need to run water to a Detached Garage that is ~ 150 ft from my house (I am on a well). I have a 1" pvc line going from the house to the garage. My question is should I come off the 1" pvc main line between the well pump and tank or should I tie into a 3/4" copper cold water line on the house side of the well tank? Before the well tank or after the tank?
