Campbell S-20XLF Pitless Adapter 1-1/4 in Pipe Well

Product Description

The CAMPBELL S-20XLF is a pitless adapter designed for residential and light-commercial well systems. A pitless adapter provides the watertight, frost-protected connection between the drop pipe inside the well casing and the horizontal service line running to the structure. This unit accommodates 1-1/4 inch pipe and is engineered to fit casing diameters ranging from 5-9/16 inches to 10-3/4 inches. Licensed well pump installers and plumbing contractors use this type of fitting to eliminate the need for a buried pitless unit pit, keeping the below-grade connection sealed and accessible from the surface.

The S-20XLF fits within the CAMPBELL S-Series pitless adapter line and is suited for new well installations as well as service replacements on existing residential submersible pump systems. Its casing range of 5-9/16 to 10-3/4 inches makes it compatible with a broad spread of standard well casing diameters commonly found in residential water well construction. Plumbing contractors and well drilling professionals are the primary installers of this component.

Key Features

• Pipe size: 1-1/4 inches for direct connection to drop pipe and service line
• Wide casing range: fits 5-9/16 to 10-3/4 inch well casings
• S-Series design for consistent fitment across CAMPBELL pitless adapter line

Compatibility

Designed as an OEM-style replacement or new-installation pitless adapter for residential well systems using 1-1/4 inch drop pipe within standard casing diameters from 5-9/16 to 10-3/4 inches.

Installation Notes

Installation must be performed by a licensed well pump installer or plumbing contractor in accordance with applicable state well construction codes and IPC guidelines. Shut off and lock out the electrical supply to the submersible pump before any well work begins. The pitless adapter is typically installed or removed using a pitless adapter tool that engages the unit from the surface without requiring excavation. Verify casing diameter and pipe thread size before installation to confirm proper fit.
