American Granby pt300nl Bronze Pitless Adapter 1 Inch

Product Description

The AMERICAN GRANBY pt300nl is a cast bronze pitless adapter designed for residential and agricultural water well systems. Cast from an 81 percent copper content alloy, this lead-free fitting meets NSF/ANSI 372 and PAS standards for safe potable water contact. The 1-inch female threaded end connection allows direct inline installation through the well casing wall, providing a watertight transition from the submersible pump drop pipe to the lateral service line. A maximum load capacity of 800 pounds supports heavy pump and pipe assemblies. Licensed well drillers, pump installers, and plumbing contractors are the primary installers of this fitting.

The pt300nl is suited for new well construction and pump replacement projects on residential, farm, and light commercial water supply systems. It is sized for nominal well casings ranging from 5 inches to 8 inches in diameter, covering the most common steel and PVC casing diameters in the field. The extended casing nipple simplifies threading and alignment during installation. Rubber inner and outer casing gaskets create a certified, approved watertight seal that prevents ground water contamination from entering the casing annulus. A built-in lowering eyelet makes lowering the pump assembly into the casing more manageable during service.

Installation Notes

Installation should be performed by a licensed well driller or pump installer in accordance with applicable state well construction codes and local plumbing regulations. Shut off all power to the submersible pump before lowering or retrieving the pump assembly. The casing wall must be cut to the correct 1-3/4-inch hole opening size before inserting the adapter body.
