What distribution box means
A distribution box is a small concrete or plastic box between the septic tank and the drainfield that splits the effluent evenly among the drainfield lines.
Also called D-box.
Where it matters on a septic job
A tipped or settled D-box overloads one line while others sit dry. Leveling or replacing it is a modest repair that can save a drainfield, worth checking before quoting a new field.
