I have about a 2 acre lawn, and about an acre in garden. I also have 30 pheasant pens that I have to water every day. I had put in underground PVC with manual valves to save money, but that becomes an issue when the temps hit 120 around here in the summer and I want to be camping. My birds were on a hose to a valve system and I manually water 6 different lines. I put in PVC out to the pens and then changed all my manual vavles over to rainbird and or orbit. I now have 4 computers and 27 valves to different lines. My house is gorgeous ight now with at least 20 varieties of Iris and then the peonie and roses, wild, and 55 different domestic ones, along with daisys and everything else that is in bloom right now including my early daylillies. the sprinklers really help with my time and relieve a little pressure when I want to be out in the woods. Toss in the color from about 25 -30 different bird species (pheasants and fowl), and its a regular kaleidiscope around here.
