Jets are weak or some seats have very little water pressure even though pumps run

Safety first: Turn off power before removing jets or opening pump unions.

• Clean filters: Remove and clean or replace all filter cartridges.
• Adjust diverter valves: Rotate the large diverter knobs on the spa top to direct flow to the desired seats. Ensure they are not stuck between positions.
• Open air controls: Turn the small air control knobs fully open to allow air mixing, which can increase perceived jet strength.
• Inspect jets: Remove individual jet inserts by turning counterclockwise and pulling out. Check for debris or calcium buildup and clean thoroughly.
• Check pump impeller: If one entire pump zone is weak, remove the pump wet end and inspect the impeller for debris or broken vanes. Replace the pump wet end if damaged.
