Distribution Box Replacement in Southern Maine
Ensure Even Wastewater Distribution & Prevent Drain Field Failure
The distribution box (D-box) is a critical component of your septic system, responsible for evenly distributing wastewater from the septic tank to the drain field. Over time, D-boxes can crack, shift, or become clogged, leading to uneven drainage, backups, and potential system failure.
At Septic Advisor, we provide professional D-box replacement services throughout Southern Maine, ensuring your system operates efficiently and prevents costly repairs.
Service Area
Portland, Westbrook, South Portland, Cumberland County, and the greater Cumberland County area (will travel to other locations upon request).
Signs You May Need a D-Box Replacement
Uneven Drainage — Some areas of your drain field may be excessively wet, while others remain dry.
Slow Drains & Backups — If sinks, showers, and toilets are draining slowly, it may indicate an issue with wastewater distribution.
Standing Water or Foul Odors — A failing D-box can cause wastewater to pool near the drain field or emit unpleasant smells.
Cracked or Collapsed D-Box — A damaged distribution box can allow solids and sludge to enter the drain field, leading to long-term damage.
Aging Septic System — If your septic system is 20+ years old, it may be time to inspect and replace key components, including the D-box.
