For submersible pumps, measure the outside diameter of the water pipe accurately, as it may differ from the nominal pipe size. Common sizes include 1 inch (approximately 1.3 inches outer diameter), 1.25 inches (approximately 1.65 inches outer diameter), 1.5 inches (approximately 1.9 inches outer diameter), and 2 inches (approximately 2.4 inches outer diameter). If your pipe does not match these sizes, please provide detailed measurements below.
