Main water line into house is a 3/4" meter and copper pipe. It is reduced to a 1/2" just after it enters the crawlspace and before making its way to the water heater. Should I tap for an irrigation line with a 3/4" pipe before the reduction or tap with a 1/2" pipe after. I am worried that if I tap before then it will screw up the flow to the house.
