The âPerc Testâ. A Perc Test (also known as âPerk Testâ, and more formally known as a Percolation Test), is a soil evaluation that tests the rate at which water drains through soil.
To run the test without digital measurements: 1  Fill the lower permeameter chamber with soil. If only one chamber is being used, test one soil sample at a time. 2  Fill the upper chamber with water. Next, open the valve, and allow water to flow through the soil.
