Can a Simple Pump Work with a PVC Well Casing?

Choosing the Right Pump and PVC Casing

A simple pump like the FloMax or the Boyce pump can be paired with a PVC well casing, but it’s essential to select a pump with a compatible maximum submergence depth and a suitable stroke length. The PVC casing should be at least 4 inches in diameter and 10 feet deep to accommodate the pump’s cylinder and stroke length. For example, the FloMax pump requires a 10-foot stroke length and a submergence depth of 8 feet, making a 10-foot deep PVC casing suitable.

PVC Material Selection and Installation

When selecting a PVC casing, look for materials that can withstand the pump’s maximum pressure rating and the water table depth. Schedule 40 or 80 PVC pipes are suitable for well casing due to their higher pressure ratings. Ensure the PVC casing is properly installed, with the top section extending 1-2 feet above ground level to facilitate easy maintenance and minimize the risk of contamination. Use a primer and cement to secure the PVC joints, and ensure a watertight seal.

Safety Considerations and Maintenance

Regular maintenance is crucial to prevent corrosion and damage to the PVC casing and the simple pump. Check the pump’s cylinder and valves for mineral buildup and clean them periodically. Inspect the PVC casing for signs of corrosion or damage, and replace it if necessary. Ensure the top section of the PVC casing remains exposed above ground to facilitate easy maintenance and monitoring.
