I get my water from an irrigation ditch located uphill from my subdivision. We have a sealed system that supplies us with raw water for lawn sprinkling at 40 lbs of pressure. I have never filtered this water but use very large brass twist in sprinkler heads 3/4 and 1/2 with the restrictors removed. I move a lot of water but I waste a lot too. I would like to water with the restrictors in place, but need a filter The water is supplied to my in ground system through a 2 inch schedule 40 pipe and valve. Any ideas about reasonably priced 2 inch filters that clean easily. the water has lots of debris at various times including snakes which I have pulled out of the sprinkler heads.
