installing an irrigation system for a house the has approx 1600sqft front 1800sqft sides and 3200sqft backyard. the way the driveway is arched around the front of the house and with all the beds we will be using a 6-8 zone system, 1 for the front, 1 for the treelawn, 1 for each side lot, 1 for the back(possible be split into 2 zones, yard is 80x20) and with 2 zones covering 3 beds. the problem is that berea, ohio has low water pressure b/c the systems are soo old, they have tried to raise the pressure and have broken water mains. any advice as to how we can make this more efficient and easier. we already have to use a mole or horizontal boring machine in 5 areas to get under the drive and a few sidewalks around the house.
