We water a 50K sq. ft. lawn using a ditch pump (50GPM) pumping lake water through 1 1/2" fire hose. Is there a sprinkler on a high tripod that we could hook the 1 1/2" hose to? This way we could set the sprinkler, let it run for 20 minutes or so, then move it. The application is a beach, we have about 2 hours early in the morning to get the lawn watered before the crowds arrive. Thanks in advance for any help.
