Important Safety Information
Always disconnect power to the pump at the circuit breaker before attempting any service or maintenance. Failure to do so can result in serious injury or death. Consult a qualified pool service professional if you are unsure about any steps. Wear appropriate personal protective equipment, such as safety glasses and gloves, during installation.
Installation Instructions
This section outlines the general procedure for replacing the diffuser. Specific pump models may have slight variations. Refer to your pump's original manual for detailed disassembly instructions.
- Disconnect Power: Ensure the pump's power supply is completely disconnected at the main circuit breaker. Verify with a voltage tester.
- Drain Pump: Close all necessary valves to isolate the pump and drain any water from the pump housing.
- Remove Pump Housing: Carefully unbolt and remove the front housing or volute of the pump to access the impeller and diffuser area.
- Remove Old Diffuser: The old diffuser is typically located directly in front of the impeller. It may be held in place by screws or simply seated. Remove any fasteners and carefully extract the old diffuser. Note its orientation.
- Inspect Impeller: While the pump is open, inspect the impeller for any damage or debris. Clean as necessary.
- Install New Diffuser: Position the new Pentair 350032 diffuser in the correct orientation, ensuring it seats properly against the pump housing and around the impeller.
- Secure Diffuser: If applicable, re-install any screws or fasteners to secure the new diffuser. Do not overtighten.
- Reassemble Pump: Reattach the pump front housing or volute, ensuring all gaskets and O-rings are correctly seated and undamaged. Tighten bolts evenly.
- Refill and Prime: Open all necessary valves, refill the pump with water, and prime the pump according to your pump's operating instructions.
- Restore Power: Once the pump is primed and all connections are secure, restore power at the circuit breaker.
- Test Operation: Start the pump and check for proper operation, ensuring there are no leaks and water flow is consistent.
Post-Installation Checks
After installing the new diffuser, perform the following checks:
- Leak Detection: Visually inspect all pump connections and housing seams for any signs of water leaks.
- Noise Level: Listen for any unusual noises from the pump, which could indicate improper assembly or a foreign object.
- Water Flow: Observe the water flow at the returns. It should be strong and consistent.
- Pressure Gauge: Check the pressure gauge on your filter system. It should be within the normal operating range for your system.
Maintenance
The Pentair 350032 diffuser itself requires no specific maintenance beyond proper installation. However, regular maintenance of your overall pump system is essential for longevity:
- Basket Cleaning: Regularly clean the pump strainer basket to prevent debris from reaching the impeller and diffuser.
- Seal Inspection: Periodically inspect pump seals and O-rings for wear and tear. Replace as needed to prevent leaks.
- Winterization: Follow proper winterization procedures for your pump and plumbing system in colder climates.
Troubleshooting
If you encounter issues after replacing the diffuser, consider the following:
- No Water Flow/Low Flow:
- Check if the pump is properly primed.
- Ensure all valves are open.
- Inspect for air leaks in the suction line.
- Verify the impeller is not clogged.
- Leaks from Pump Housing:
- Ensure all bolts are tightened evenly.
- Check if gaskets and O-rings are correctly seated and undamaged.
- Unusual Noise:
- Confirm no debris is trapped in the impeller or diffuser.
- Check for proper alignment of pump components.
If problems persist, contact a qualified pool service technician.
