TL;DR
A distribution box is the concrete or plastic chamber in a septic system where effluent leaving the tank is divided evenly among the drainfield's lateral lines. Perfect level is its whole job: a box tilted by frost or settling sends most of the flow to one trench, saturating it into failure while the others sit dry, and adjustable eccentric levelers on the outlets exist precisely to correct this.
What it means
A distribution box is the concrete or plastic chamber in a septic system where effluent leaving the tank is divided evenly among the drainfield's lateral lines. Perfect level is its whole job: a box tilted by frost or settling sends most of the flow to one trench, saturating it into failure while the others sit dry, and adjustable eccentric levelers on the outlets exist precisely to correct this. It is opened and checked during septic inspections, and an unequal biomat pattern across the field often traces back to this one buried component.
