4. Setup and Installation
Follow these steps carefully to replace the diffuser in your Hayward SuperPump.
4.1. Preparation
- Turn off all power to the pool pump at the main circuit breaker.
- Close any necessary valves to prevent water flow to and from the pump.
- Open the air relief valve on your filter to release any pressure in the system.
- Drain the pump by removing the drain plugs.
4.2. Removing the Old Diffuser
- Remove the bolts or clamps securing the pump housing or volute.
- Carefully separate the motor assembly from the pump housing.
- Locate the old diffuser, which is typically situated between the impeller and the pump housing.
- Gently remove the old diffuser. Inspect the area for any debris or damage and clean as necessary.
4.3. Installing the New Diffuser
- Position the new Hayward SPX1616B Diffuser into the pump housing, ensuring it seats correctly. The diffuser should align with the impeller and the pump's inlet.
- Ensure any gaskets or O-rings are properly seated and in good condition. Replace if necessary.
- Carefully reassemble the pump housing and motor assembly, ensuring all components are aligned.
- Secure the pump housing with the original bolts or clamps, tightening them evenly to prevent leaks.

4.4. Post-Installation
- Open all closed valves to allow water flow to the pump.
- Prime the pump by filling the pump basket with water until it overflows. Secure the pump lid.
- Turn on the power to the pump at the circuit breaker.
- Check for any leaks around the pump housing. If leaks are present, turn off power, depressurize, and re-tighten the housing bolts or inspect gaskets.
5. Operating Instructions
The diffuser is a static component within the pump that directs water flow from the impeller to the pump's outlet. Once correctly installed, it operates passively as part of the pump's normal function. No specific operational adjustments are required for the diffuser itself.
Refer to your Hayward SuperPump owner's manual for detailed operating instructions for the complete pump system.
6. Maintenance
Regular inspection and maintenance of your pump system, including the diffuser, will ensure optimal performance and extend the life of your equipment.
- Visual Inspection: Periodically inspect the diffuser (during routine pump maintenance or when opening the pump) for cracks, wear, or debris accumulation.
- Cleaning: If debris is found on the diffuser, carefully remove it. Ensure water passages are clear.
- Gasket/O-ring Check: Always inspect the pump housing gasket/O-ring when the pump is opened. Replace if it shows signs of wear, cracking, or flattening to prevent leaks.
7. Troubleshooting
If you experience issues after replacing the diffuser, consider the following common problems:
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump not priming or low flow | Improperly seated diffuser; air leak in pump housing; clogged impeller. | Re-check diffuser seating; inspect and replace pump housing gasket/O-ring; clean impeller. |
| Water leak from pump housing | Improperly tightened housing bolts; damaged gasket/O-ring. | Ensure housing bolts are tightened evenly; inspect and replace gasket/O-ring. |
| Unusual noise from pump | Debris in pump; impeller rubbing diffuser. | Turn off power, open pump, remove debris; ensure diffuser is correctly seated and not interfering with impeller rotation. |
