A Key Component of any Sewage Disposal System
The distribution box, or D-box, is a key component of any sewage disposal system. Effluent (wastewater) leaves the septic tank and enters the distribution box, where the effluent must be evenly divided and discharged to the leaching system. It is critical that they are set level to prevent unequal distribution, which is a main factor of failed leach fields. Polylok© equalizers can be used to equalize an uneven D-box. The easiest way to test for levelness is to add water to the D-box.
