My goal is to find if I can irrigate a small area from an artesian well without a pump. Microirrigation (Spot Spitters) works at the pressure, according to their web site. Thanks for the DC valve info. I am reading the product info about the Rain Bird Easy Rain valves.

I am not sure how large an area I can irrigate witout a pump. Well driller put 2 pipes (2" and 1 1/2") coming out of 4" pvc well casing.
