Pool cleaners are essential for maintaining a sparkling clean pool, but when they malfunction, it can be frustrating. A common issue with Polaris pool cleaners is a faulty backup valve. Troubleshooting your Polaris pool cleaner’s backup valve is a straightforward process that can save you time and money.
The backup valve is responsible for reversing the cleaner’s direction when it gets stuck. If your Polaris isn’t moving or seems to be trapped in one area, the backup valve might be the culprit. By following a few simple steps, you can identify and fix the problem, getting your pool cleaner back to work in no time.
Understanding how the backup valve functions is key to effective troubleshooting. This guide will walk you through the process, from checking for debris to replacing parts if necessary. With these tips, you’ll be able to diagnose and resolve backup valve issues quickly, ensuring your pool stays clean and inviting all season long.

1. Check Valve Timing
The backup valve’s timing is crucial for your Polaris pool cleaner’s performance. If it’s not cycling correctly, your cleaner won’t move efficiently or clean thoroughly.
Start by observing the valve’s operation. It should cycle approximately every 3 minutes. If it’s cycling too quickly or not at all, you’ll need to adjust it.
Locate the adjustment screw on the valve body. Use a flathead screwdriver to turn it clockwise for slower cycles or counterclockwise for faster ones. Make small adjustments, then test the cleaner’s movement.
Check for debris around the valve’s moving parts. Small pebbles or leaves can disrupt its timing. Clean the area thoroughly if you spot any obstructions.
Remember, water pressure affects valve timing. If your pool pump’s output has changed, you may need to readjust the valve to compensate. Aim for a balance where your cleaner moves steadily without getting stuck.
2. Clear Debris Obstruction
Inspect the backup valve for any visible debris or obstructions. Remove leaves, twigs, or other foreign objects that may be blocking the valve’s mechanism. Use your hands or a small brush to gently clear away buildup.
Check the valve’s internal components for trapped debris. Unscrew the valve housing and examine the moving parts inside. Clean out any sand, dirt, or small particles that could impede its operation. Reassemble the valve carefully after cleaning.
Flush the backup valve with clean water to dislodge any remaining debris. Connect a garden hose to the valve inlet and run water through it for several minutes. This can help clear out stubborn particles and ensure smooth operation.
3. Verify Water Pressure
Adequate water pressure is crucial for your Polaris pool cleaner’s backup valve to function properly. Start by checking the pressure gauge on your pool’s filter system. If it’s below 25 PSI, you’ll need to address this issue first.
Clean or backwash your pool filter to improve water flow. A clogged filter can significantly reduce pressure, hampering your cleaner’s performance. Remember to turn off the pump before cleaning the filter.
Next, inspect the cleaner’s hose for any kinks or twists. Straighten out any bends to ensure smooth water flow. Check the hose connections as well, tightening them if necessary.
If pressure remains low, examine your pool’s skimmer and pump baskets for debris. Clean them out to improve water circulation. Don’t forget to check the impeller in your pump for any obstructions.
Consider using a flow meter to measure the gallons per minute (GPM) reaching your Polaris cleaner. Most models require 28-32 GPM for optimal performance. Adjust your system if needed to meet these specifications.
4. Assess Need for Valve Replacement
Inspect your Polaris pool cleaner backup valve for signs of wear and tear. Look for cracks, leaks, or discoloration that might indicate deterioration. Check if the valve flapper moves freely and closes properly.
Test the valve’s functionality by running your pool pump. If water doesn’t flow through the valve or it doesn’t alternate directions every few minutes, it may need replacement.
Consider the age of your backup valve. These components typically last 2-3 years with regular use. If yours is older, it might be time for a new one.
Examine the O-rings and seals around the valve. Damaged or worn seals can cause leaks and reduce efficiency. Replace these if they appear brittle or cracked.
If you’ve noticed a significant decrease in your cleaner’s performance or it’s getting stuck more often, the backup valve could be the culprit. A new valve might solve these issues and improve overall cleaning efficiency.
5. Inspect Hose Connections
Check the connections between your Polaris pool cleaner’s hoses and the backup valve. Loose or damaged connections can cause improper water flow, reducing the valve’s effectiveness.
Examine each connection point carefully. Look for signs of wear, cracks, or debris buildup. Ensure all O-rings are present and in good condition. These small rubber rings create a watertight seal between components.
Clean the connections if you spot any dirt or algae. Use a soft brush and pool-safe cleaner to remove buildup. Once clean, reconnect the hoses firmly. You’ll hear a click when they’re properly seated.
Test the connections by running your hand along them while the system is on. You shouldn’t feel any water leaking. If you do, double-check that everything is tightened correctly.
Consider replacing worn hoses or connectors. Over time, UV exposure and chemicals can degrade these parts. Fresh components can significantly improve your backup valve’s performance.
6. Ensure Proper Cleaner Position
Position your Polaris pool cleaner correctly to maximize its cleaning efficiency. Start by placing it in the shallow end of the pool, ensuring the backup valve and hose float are on the water’s surface.
Check that the cleaner’s wheels are in contact with the pool floor. If it’s not sitting flat, adjust the hose or reposition the unit. Make sure the hose isn’t tangled or kinked, as this can impede movement.
Observe the cleaner’s movement for a few minutes. It should travel in a random pattern, covering different areas of the pool. If it’s stuck in one spot or moving in circles, reposition it and check for any obstructions.
Remember to keep the hose length appropriate for your pool size. Excess hose can cause the cleaner to get tangled, while too short a hose limits its reach. Adjust as needed for optimal coverage.
7. Adjust Water Jets
Check your Polaris pool cleaner’s water jets for optimal performance. Start by turning off the pool pump. Locate the water jets on the cleaner’s body – typically found near the wheels or on the underside.
Examine each jet for debris or blockages. Use a small brush or toothpick to gently clear any obstructions you find. This simple step can significantly improve your cleaner’s effectiveness.
Next, adjust the jet directions. Most models allow you to rotate the jets slightly. Aim them towards the rear of the cleaner at about a 45-degree angle. This positioning helps propel the cleaner forward and improves its cleaning path.
If your model has adjustable pressure settings, experiment with different levels. Start at a medium setting and observe how the cleaner moves. Increase or decrease as needed for better coverage of your pool’s surface.
Remember to check the jets regularly, especially after cleaning heavily soiled areas. Keeping them clear and properly aligned will ensure your Polaris cleaner operates at peak efficiency.
