Jets are weak or have very little pressure even though the pump is running.

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

• Clean or remove filter: Take out the Dynasty Spas filter cartridge and rinse thoroughly. Test jet strength briefly with the filter removed.
• Check valves: Ensure all slice valves around the jet pump and suction lines are fully open.
• Bleed air from pump: Loosen the union on the jet pump discharge slightly to release trapped air until water flows, then retighten.
• Inspect jets: Remove individual jet inserts and check for debris or calcium buildup. Clean and reinstall.
