I have used these to spray new grass seed at many spots on our 15 acres of well water. I bought a 550 gallon plastic tank, 150 gpm pump, 2 inch suction hose and 2 inch drain hose. I then used this coupler with a fire nozzle to get well water up to 50 feet from the tank. Very easy to use, you can use a powerful fine spray or powerful jet of water to reach remote areas. The nozzle is switched off in both directions.
