Single and multi-size washing balls are designed with diagonal ribbing along the periphery. This design, along with adequate head pressure, creates a jet of water, which causes a jetting action along the pipe walls. This jetting action will wash away packed sand, rock, grease, and other debris.

The multi-size washing ball is built with the same design and construction as the domehead plugs. These balls have a water fill port that allows the user to control the buoyancy. This feature enhances the performance of these products.
