4. Setup and Installation
Follow these steps for proper installation of your AQUASTRONG sand filter pump. Refer to the installation video for visual guidance.
Video: AQUASTRONG Sand Filter Pump Installation Quick Guide. This video provides a step-by-step visual walkthrough of the sand filter pump assembly and connection process.
- Position the Pump: Place the pump and filter tank on a firm, level surface near your pool, ensuring it is below the pool's water level for optimal priming.
- Secure Pump to Base: Attach the pump motor unit to the base platform.
- Add Filter Media: Remove the top cover of the filter tank. Carefully add the recommended amount of filter sand (100 lbs) or filter balls (3.1 lbs). Ensure the standpipe is centered during this process.
- Install 6-Way Valve: Place the 6-way valve onto the top of the filter tank, aligning it with the standpipe. Secure it firmly with the provided clamp or bolts.
- Connect Hoses:
- Connect the pool's skimmer line (suction) to the pump inlet.
- Connect the pump outlet to the 'PUMP' port on the 6-way valve.
- Connect the 'RETURN' port on the 6-way valve to the pool's return line.
- Connect a backwash hose to the 'WASTE' port on the 6-way valve, directing it to an appropriate drainage area.

- Install Pressure Gauge: Screw the pressure gauge into the designated port on the 6-way valve.
- Prime the Pump: Fill the pump's strainer basket with water until it overflows. Replace the lid.
- Electrical Connection: Connect the pump to a properly grounded electrical outlet.

5. Operating Instructions
The 6-way multi-port valve allows for various operational modes. Always turn off the pump before changing the valve position.
Image: Diagram illustrating the six functions of the multi-port valve: Filter, Backwash, Rinse, Waste, Recirculate, and Closed.
- FILTER: (Normal filtration) Water is pumped through the sand bed, filtered, and returned to the pool. This is the primary operating mode.
- BACKWASH: (Cleaning filter) Reverses the flow of water through the sand bed to flush out trapped debris to the waste port. Perform when pressure gauge reads 8-10 PSI above starting pressure.
- RINSE: (After backwash) Used after backwashing to flush out any remaining dirty water from the valve and sand bed to the waste port, preventing it from returning to the pool.
- WASTE: (Bypasses filter) Drains water directly from the pool to the waste port without passing through the filter. Useful for vacuuming heavy debris or lowering pool water level.
- RECIRCULATE: (Bypasses filter) Circulates pool water without filtering it through the sand bed. Useful for mixing chemicals.
- CLOSED: (Shuts off flow) Closes all flow to the filter and pump. Use this setting only when the pump is off and for servicing the pump or filter.
Monitor the pressure gauge regularly. An increase in pressure indicates that the filter needs backwashing.

6. Maintenance
Regular maintenance ensures optimal performance and longevity of your sand filter pump.
- Backwashing: When the pressure gauge reads 8-10 PSI above its clean starting pressure, it's time to backwash. Turn off the pump, set the valve to 'BACKWASH', turn on the pump, and run until the water in the sight glass is clear (approx. 2-3 minutes). Turn off the pump.
- Rinsing: After backwashing, turn off the pump, set the valve to 'RINSE', turn on the pump, and run for 30-60 seconds. Turn off the pump.
- Return to Filter: Turn off the pump, set the valve to 'FILTER', and turn on the pump for normal operation.
- Clean Strainer Basket: Periodically check and clean the pump's detachable strainer basket to remove large debris like leaves and hair. Turn off the pump, close necessary valves, remove the basket lid, empty debris, and replace.

7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Low water flow / Poor filtration | Clogged filter sand; Clogged strainer basket; Air leak in suction line; Low water level in pool. | Backwash and rinse filter; Clean strainer basket; Check all connections for leaks; Ensure adequate pool water level. |
| Pump not priming | Strainer basket not full of water; Air leak in suction line; Clogged impeller. | Fill strainer basket with water; Check and tighten all connections; Inspect and clean impeller. |
| Water returning to pool is cloudy | Filter sand needs backwashing; Incorrect filter media; Damaged internal filter components. | Backwash and rinse thoroughly; Verify correct type and amount of filter sand; Contact support if internal damage is suspected. |
| Pump not starting | No power; Thermal overload tripped; Motor issue. | Check power supply and circuit breaker; Allow motor to cool and reset; Contact qualified electrician or support. |
