What Are Leach Lines, and When Should They Be Replaced?
Leach Line Percolation Rate. For a leach line to work properly, the liquid in the pipes needs to percolate (or, soak) into the soil at the correct rate. If the liquid percolates 1-inch into the soil in less than five minutes, the liquid is moving downward too quickly to be treated. If the liquid drops 1-inch is about an hour or more, the liquid ...Web
