Built this irrigation sprinkler system out of 1" pvc pipe. It is 30' long and is self supporting. Can be easily moved, or burried in tilled soil prior to planting. Impact sprinklers are 15' a part and water stream should over lap. Each sprinkler has a ball valve in case head needs to be shut off. Center sprinkler has a hose spicket in case hose watering is desired or lines need to be flushed. This will be placed in pumkin patch and water piped to it from storage tank. Hope to test it tomorrow.
