Pump cannot be primed after winterization; it just sucks air and never fills.

Safety first: Ensure all valves are correctly positioned and pump is off before priming.

De-winterize system:

• Remove all winterizing plugs from skimmers, main drains, and suction lines.
• Close any drain cocks on the filter, heater, or chlorinator.
• Install and tighten the Speck pump housing drain plugs.

Prime carefully:

• Fill the pump housing completely with water through the strainer opening.
• Set valves to draw from the easiest suction source (usually main drain) and start the pump.

If priming still fails, check for suction-side leaks or blockages.
