The distribution box is a most important component of a septic system. Without even distribution of effluent, the drain field will be used unevenly. As trenches in the drainfield become overloaded, portions of the drain field will fail. The result of a poorly functioning septic distribution box is untreated wastewater appearing on the surface of the soil in the drainfield.
Make the right choice.
