Jets are weak or some seats have very little water pressure.

Safety: Keep hands clear of moving parts; pumps may start automatically during filter cycles.

• Clean filter: Remove and thoroughly rinse the Hanscraft filter cartridge. Replace if older than recommended service life.
• Adjust diverter valves: Turn any top-side diverter valves to direct flow to the weak seats. Ensure they are not stuck between positions.
• Soak jets: Remove jet inserts and soak them in a 50/50 white vinegar and water solution to dissolve scale. Rinse and reinstall.

If only one area remains weak, there may be a partial blockage in that plumbing line requiring professional inspection.
