Ever heard of a septic distribution box? π€
It's a small box that sits between your septic tank and your drain field, and its whole job is to split wastewater evenly across every drain line. When it fails, from cracking, settling, or roots working their way in, the flow gets uneven and one part of your drain field takes on way more than it should. Left alone, that can shorten the life of the entire field.
The good news: repairing or replacing a D-box is one of the more straightforward septic fixes when it's caught early. Here's how we handle it, step by step π
β
Locate and carefully expose the box
β
Inspect for damage, collapse, and root intrusion
β
Remove the broken or failing parts
β
Install a new, level D-box and reconnect the lines
β
Level it and test the flow to make sure it's evenly distributed
β
Backfill, grade, and restore the yard
