I am tapping a new irrigation system into my main household water line. I have a 3/4" meter and main line coming into my crawlspace. It is immediately reduced to a 1/2" line running to the water heater then dispersed thruout the house. I want to know if I can tap into the 3/4" section before the reduction giving more flow to the irrigation but not effect the flow to the household fixtures or do I have to tap into the line after the reduction and use a 1/2" feed to the irrigation.
