An Impact Sprinkler is a common type of sprinkler used for watering large or long lawns and gardens.

In an Impact Sprinkler, a swinging arm bounces the stream of water pushed out through the sprinkler head forcing the head to move and distribute the water in a circular pattern.

This is different to Oscillating sprinkler which has a long tube, with multiple sprinkler holes, that slowly moves back & forth with the force of water.

How to adjust the spray distance in an Impact Sprinkler?

• - Using Diffuser Pin - The diffuser pin is a large screw anchored to the base of the sprinkler head. Adjust the Diffuser pin to either create a long throw distance with a solid stream of water or a shorter throw distance with a diffused (mist) spray pattern.
• - Using Deflector Shield - Turn the distance control knob on top of the sprinkler to either MIN or MAX arrow position to suit your application.
