When you think about your septic system, you likely think of two main parts: the tank and the drainfield. But do you know what a distribution box is? Also known as a d-box, the distribution box is an essential part of your system. What’s more, knowing how your distribution box works is crucial for keeping your system healthy and well.
THE DISTRIBUTION BOX IS PART OF YOUR LEACH FIELD
A septic d-box is a container that receives wastewater from the septic tank. It’s buried underground in your leach field. The box is in charge of equally distributing the wastewater into the ground via field lines.
HOW DOES IT WORK, EXACTLY?
Like most of your septic system, the distribution box uses gravity. Since the leach field and box are located below the septic tank, the wastewater moves downhill as it enters the container. Additionally, the box has several holes with rotating devices. The devices control the wastewater flowing outward, ensuring an even amount enters each area of the leach field.
A working, reliable septic system relies on this function. If your distribution box is unable to evenly re-distribute wastewater, the liquid will accumulate in one section of your leach field. This can overwhelm the area, compromising the overall efficiency of the field.
COMMON DISTRIBUTION BOX PROBLEMS
If you notice flooding in one part of your drainfield, take note. Your distribution box is likely broken or blocked—and needs to be repaired or replaced.
This can happen due to several reasons, including:
- Natural wear and tear
- Sludge accumulation
- Improper septic system care
- Invading tree roots
- Driving heavy machinery over the box
- Flooding and other inclement weather conditions
The pipes leading to or from the box can also become clogged or damaged. Similarly, the rotating devices connected to the openings may fail, resulting in uneven liquid distribution.
Regardless, it’s important to call Paradise Valley Septic if you suspect a distribution box problem. The sooner the box is fixed or replaced, the sooner you can prevent larger septic issues down the line.
DIFFERENT TYPES OF DISTRIBUTION BOXES
Distribution boxes can be made of concrete or plastic. As you can imagine, concrete versions are significantly stronger than their plastic counterparts. The boxes are also available in various sizes and shapes. The best choice depends on your specific tank size and type.
