PVC Sump Pump Drain System Diagram - Installation Guide & Components #2025353 (License: Personal Use)

This technical diagram illustrates a standard PVC sump pump discharge configuration, featuring a vertical cap with an air hole (optionally fitted with an air valve) to prevent vacuum lock, a PVC “T” fitting for branch access or overflow, and elbows for directional routing. The system connects the sump basin to a drain line, with water level indicated at the tank inlet and flow paths shown via blue arrows. Proper sizing and venting ensure efficient drainage and avoid backflow or airlock issues.
