Concrete Distribution Boxes
To complete our extensive line of septic tanks, Concrete Building Supply stocks a complete line of quality precast distribution boxes. Our distribution boxes are produced using Polylok© Low Pressure Pipe Seals. These seals require no sealing or mortaring, and accept pipe from two to four inches. In addition several pipe classes will work including, Schedule 40, sewer and drain, and SDR 35 pipe. Distribution boxes are available with 3 inlets, 5, 6, 8, or 10, or 12 outlets.
Distribution boxes are a small but very important part of any sewage disposal system. Effluent leaving the septic tank enters the distribution box; here the effluent must be uniformly divided and discharged to the leaching system. All discharge pipes must receive equal amounts of effluent if the system is to function properly. If the fluid flow is unequal, one section of the field will receive amounts of effluent in excess of the design amount and will fail. At the same time, the rest of the field is receiving little or no effluent.
