Irrigation Pump with Well-Mate Bladder Tank: No Pressure After Winter

System drained in fall. Spring startup: pump runs but no line pressure. Tank air pressure only 4 PSI (switch set at 35). No water from air valve.

Primary Suspect

Pump lost prime. Check suction line for leaks. Pull suction line to inspect foot valve. Re-prime pump: remove intake plug, fill with water, replace plug, start pump.
