It is the basin component of the ZOELLER 31-1105 duplex basin and lid assembly, paired with the 17-0451 fiberglass cover. Measuring 30 inches in diameter and 36 inches in height, this basin is built for below-grade installation in residential and light commercial sewage collection applications. The seam-free construction eliminates leak points that are common in multi-piece basins. Licensed plumbers and pump service technicians are the primary installers of this unit.\u003c\/p\u003e\n\u003cp\u003eThis basin is designed for duplex sewage pump systems where redundant pump operation is required. The 30-inch diameter provides sufficient sump volume for two sewage pump installations. It ships as the basin-only component within the 31-1105 assembly and is used in applications requiring a solid cover configuration. The built-in inlet, vent, and discharge provisions accommodate standard plumbing rough-in without field fabrication.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eOne-piece, seam-free polyethylene structural foam construction eliminates leak-prone joints\u003c\/li\u003e\n  \u003cli\u003e30-inch diameter by 36-inch depth accommodates duplex pump configurations\u003c\/li\u003e\n  \u003cli\u003e2-inch discharge outlet for standard sewage pump connection\u003c\/li\u003e\n  \u003cli\u003e2-inch vent flange supports code-required basin venting\u003c\/li\u003e\n  \u003cli\u003e4-inch combination inlet hub for flexible influent piping connections\u003c\/li\u003e\n  \u003cli\u003eIncludes gasket and hardware; inspection plate provided for service access\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eThe 31-1097 basin is the basin component of the ZOELLER 31-1105 30-inch by 36-inch duplex basin and lid assembly.
