Jets are weak or some seats have very low water pressure

Safety: Turn off power at the GFCI breaker before removing filters or opening unions.

• Clean filters: Remove all filters and rinse thoroughly. Test jet strength with filters removed to see if flow improves.
• Check diverter valves: Rotate any topside diverter valves fully in both directions to ensure they are not stuck between positions.
• Open all jets: Many Artesian jets twist to open/close. Turn each jet face counterclockwise to fully open.
• Bleed air from pump: Loosen the pump union slightly to release trapped air, then retighten.
• Inspect for debris: If one area is weak, remove a jet insert and check for debris in the jet body or plumbing.

If flow remains weak with clean filters and open valves, the pump impeller may be worn or partially blocked and the pump may need service or replacement.
