Understanding Priming and Why It Matters

Before we jump into solutions, let’s understand what priming means for your Pentair SuperFlo VS pump. Priming is the process of removing air from the pump and suction lines, allowing the pump to draw water efficiently. When air is present, the pump struggles to create the necessary suction, leading to a prolonged priming cycle or even a complete failure to prime.

A properly primed pump ensures:

• Efficient water circulation
• Optimal filtration
• Reduced energy consumption
• Prolonged pump life

Ignoring a slow priming cycle can lead to:

• Overheating of the pump motor
• Damage to the impeller
• Increased wear and tear on the pump components

Step-by-Step Guide to Shortening the Priming Cycle

Step 1: Clean the Skimmer and Pump Baskets

The first and easiest step is to check and clean both the skimmer and pump baskets. Debris accumulation in these baskets can severely restrict water flow, making it harder for the pump to prime.

1. Turn off the pump: Always turn off the pump before performing any maintenance.
2. Clean the skimmer basket: Remove the skimmer basket from the skimmer housing. Discard any leaves, twigs, and other debris. Rinse the basket thoroughly with a garden hose.
3. Clean the pump basket: Open the pump lid (usually a clear, screw-on cover). Remove the pump basket and clean it as you did with the skimmer basket. Make sure no debris is stuck in the basket or the housing.
4. Reinstall the baskets: Place the cleaned baskets back into their respective housings. Ensure they are seated correctly.
5. Fill the pump basket housing with water: Before replacing the pump lid, fill the pump basket housing with water. This helps to initiate the priming process.
6. Secure the pump lid: Replace the pump lid and ensure it is tightly sealed. The O-ring should be clean and properly seated to prevent air leaks.

Step 2: Inspect for Leaks in Plumbing Connections

Air leaks in the suction-side plumbing are a common cause of priming issues. Even small leaks can allow air to enter the system, making it difficult for the pump to establish suction.

1. Visually inspect all connections: Check all pipe connections, valves, and fittings on the suction side of the pump (the pipes leading into the pump). Look for any signs of cracks, loose fittings, or damaged seals.
2. Check unions and fittings: Pay close attention to unions (threaded connections that allow you to disconnect pipes) and other fittings. Ensure they are properly tightened.
3. Inspect valves: Examine all valves (e.g., gate valves, ball valves) for leaks around the valve stem or body. Make sure they are in good working condition and properly aligned.
4. Seal any leaks: If you find any leaks, repair them immediately. You may need to tighten fittings, replace O-rings, or use Teflon tape to seal threaded connections. For more significant leaks, you might need to replace the damaged pipe or fitting.

Step 3: Verify Valve Positions

Incorrect valve positions can restrict water flow to the pump, hindering the priming process. Make sure all valves are properly aligned to allow water to flow freely from the pool to the pump.

1. Identify all valves: Locate all valves in your pool’s plumbing system, including skimmer valves, main drain valves, and any other isolation valves.
2. Ensure proper alignment: Verify that the valves are positioned to allow water to flow from the skimmer(s) and main drain to the pump. Typically, the valves should be fully open or set to the desired ratio of skimmer to main drain flow.
3. Adjust as needed: If you find any valves that are partially or fully closed, adjust them to the correct position.

Step 4: Adjust Pump Speed Settings

The Pentair SuperFlo VS pump has variable speed settings. Increasing the pump speed during the priming cycle can help to establish suction more quickly.

1. Access the pump’s control panel: Locate the control panel on your Pentair SuperFlo VS pump.
2. Increase the speed setting: Use the control panel to increase the pump’s speed setting. A higher RPM (revolutions per minute) will generate more suction.
3. Monitor the priming process: Observe the pump as it attempts to prime. You should see water filling the pump basket housing and air being purged from the system.
4. Reduce speed after priming: Once the pump is primed and water is flowing steadily, reduce the speed setting to your normal operating level. This will save energy and reduce wear and tear on the pump.

Note: Consult your Pentair SuperFlo VS pump manual for specific instructions on adjusting the speed settings. The optimal priming speed may vary depending on your pool’s plumbing configuration.

Step 5: Check the Impeller for Obstructions

The impeller is a rotating component inside the pump that creates the suction necessary to draw water. If the impeller is blocked by debris, the pump will struggle to prime.

1. Turn off the pump and disconnect power: Always turn off the pump and disconnect the power supply before working on the impeller.
2. Access the impeller: You may need to remove the pump lid and basket to access the impeller. Depending on the pump model, you might also need to remove a volute or diffuser.
3. Inspect the impeller: Carefully inspect the impeller for any signs of blockage. Look for leaves, twigs, hair, or other debris that may be lodged in the impeller vanes.
4. Remove any obstructions: Use a small tool (e.g., a screwdriver or pliers) to carefully remove any debris from the impeller. Be careful not to damage the impeller vanes.
5. Reassemble the pump: Once the impeller is clear, reassemble the pump components in the reverse order of disassembly.

Step 6: Lubricate O-Rings

O-rings are used to create a watertight seal between various pump components, such as the pump lid and the volute. If the O-rings are dry, cracked, or damaged, they can allow air to enter the system, hindering the priming process.

1. Locate the O-rings: Identify all O-rings in the pump assembly, including the pump lid O-ring, the volute O-ring, and any other O-rings used in the pump’s plumbing connections.
2. Inspect the O-rings: Examine the O-rings for any signs of damage, such as cracks, tears, or flattening.
3. Lubricate the O-rings: Apply a small amount of silicone-based lubricant to the O-rings. This will help to create a better seal and prevent air leaks.
4. Replace damaged O-rings: If you find any O-rings that are damaged, replace them with new ones. Be sure to use the correct size and type of O-ring for your pump model.

Step 7: Prime the Pump Manually

If the pump still struggles to prime after performing the above steps, you can try priming it manually.

1. Turn off the pump: Ensure the pump is turned off.
2. Open the pump lid: Carefully open the pump lid.
3. Fill the pump basket housing with water: Use a garden hose or bucket to fill the pump basket housing completely with water.
4. Close the pump lid: Securely close the pump lid, ensuring the O-ring is properly seated.
5. Turn on the pump: Turn on the pump and observe the priming process. The pump should now have a head start in establishing suction.
