2. Setup and Installation
Follow these steps for proper assembly and installation of your sand filter pump system.
- Position the Pump: Place the pump securely on its base and fasten it firmly using the provided screws.
- Prepare Center Pipe: Insert the center pipe inside the filter tank. Attach the laterals to the bottom of the center pipe. Ensure the laterals are properly seated.
- Add Filter Media: Carefully add the recommended amount of filter sand (not included) into the tank. The 22-inch tank holds up to 250 lbs of sand. Ensure the center pipe remains vertical and centered while adding sand.
- Install Multi-Port Valve: Align the multi-port valve with the center pipe and carefully place it on top of the sand filter tank. Secure it firmly with the locking ring and bolts. Tighten evenly to ensure a proper seal.
- Prepare Adaptors and Pump Connections: Apply Teflon tape to all threaded accessories, including the pressure gauge. Firmly apply adaptors to your tank and pump connection points. Insert the strainer basket into your pump and firmly lock the lid.
- Establish Pump-Filter Connection: Install O-rings to your heavy-duty connection hose. Thread the hose to your pump and multi-port valve.
- Install Filter Hoses: Insert filter connection hoses to the threaded hose adaptors as needed and secure them with clamps.
- Attach Pressure Gauge: Firmly thread the pressure gauge into the multi-port valve to complete your sand filter system.

3. Operating Instructions
The integrated 7-way multi-port valve provides quick and easy settings for optimal filtration performance. Always turn off the pump before changing valve settings.
- Filter: Normal filtering mode. Water passes through the sand media, trapping debris.
- Backwash: Cleans the filter media by reversing water flow, sending trapped debris to waste. Perform when the pressure gauge reading increases by 8-10 PSI above its clean pressure.
- Rinse: Used after backwashing to settle the sand bed and flush out any remaining debris from the valve.
- Waste: Bypasses the filter and sends water directly to waste, useful for lowering pool water level or vacuuming heavy debris.
- Recirculate: Circulates pool water without passing it through the filter media.
- Closed: Shuts off all flow to the filter and pump. Use for servicing the pump or filter.
- Winter: Used for winterizing the system.
Monitor the pressure gauge regularly. An increase in pressure indicates the filter needs backwashing. A decrease in pressure may indicate a leak or pump issue.
4. Maintenance
Regular maintenance ensures the longevity and efficiency of your sand filter pump.
- Sand Replacement: Filter sand typically lasts approximately 5 years before replacement, depending on water chemistry and backwashing frequency.
- Backwashing: Backwash the filter when the pressure gauge reads 8-10 PSI above its normal clean operating pressure. Follow with a rinse cycle.
- Strainer Basket: Periodically check and clean the pump's strainer basket to prevent clogs and maintain optimal flow.
- Winterizing: Before freezing temperatures, ensure the system is properly drained and set to the 'Winter' position to prevent damage.
5. Troubleshooting
If you encounter issues with your sand filter pump, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Low Water Flow | Clogged strainer basket, dirty filter sand, air leak in suction line, low water level. | Clean strainer basket, backwash filter, check for air leaks, ensure adequate water level. |
| Water Not Clearing | Insufficient filtration time, improper chemical balance, worn filter sand. | Increase filtration time, test and adjust pool chemicals, consider replacing filter sand. |
| Water Leaking | Loose connections, worn O-rings, cracked housing. | Tighten all connections, inspect and replace O-rings, check housing for damage. |
| Pump Not Priming | Low water level, air leak in suction line, clogged strainer basket. | Ensure adequate water level, check and seal all suction line connections, clean strainer basket. |
