Pump runs but filter pressure is very low and there is little suction at the skimmer.

Safety first: Turn off power before opening baskets or valves.

Steps to restore suction:

• Clean baskets: Empty all skimmer and Jacuzzi pump baskets.
• Check valves: Ensure suction valves are fully open and handles are intact.
• Inspect for air leaks: Service the pump lid O-ring and tighten suction unions.
• Check for line blockage: If one suction source (e.g., main drain) is weak, try isolating it with valves to identify a blocked line.

Stubborn suction issues may require professional line clearing.
