Polylok's dipper box guarantees uniform dosing for leaching systems. The Dipper is designed on the basic pivot and balance principle which insures equal distribution. The system works in unity instead of a "trickle effect" by providing equal flow distribution to each outlet. Polylok's Dipper is easily installed in any septic system. Whether existing, new, reclining or flat — the action of the Dipper allows the entire system to work in unison. Insist on the DIPPER.
