Troubleshooting Your Pool Pump Suction Issues: Common Solutions Explained
This article is designed to help pool owners understand and resolve the common issues related to their pool pump not having enough suction. Whether it's a worn out pump, obstructed pipes, or air escaping, we'll guide you through simple steps to diagnose and fix these problems.
Why Your Pool Pump is Losing Suction: Common Causes and Fixes
Often, a pool pump failing to provide adequate suction can be resolved with simple fixes. Here are some of the top causes of poor suction and their corresponding solutions:
1. Check Your Valve Settings and Clear Jets
Ensure that the valves upstream and downstream from your pump are fully open. A pool pump can draw water from multiple skimmers and the drain at the bottom of the pool. It is more efficient when all valves for these sources are open, and the jets are open and unobstructed. Ensure that the water level is above the midpoint of the skimmer window, ideally near the top of the window. This simple step can significantly reduce the pump's workload and improve suction.
2. Remove Debris from Skimmers and Filters
Trash or debris in skimmer baskets or the pump basket can clog the pump and reduce suction. Regularly checking and clearing these can resolve the issue. If the problem persists, consider checking the filter. A clogged cartridge filter or a dirty sand filter may require cleaning or replacement.
3. Verify the Filter Functioning Properly
If your pool has a Hayward Multiport Valve, you can test the filter by switching it to the "Recirculate" mode. If the pump starts drawing water in this mode, it indicates a filter problem, such as a clogged cartridge or the need for backwashing.
4. Check for Air Entrapment
Pool pumps are expert at pumping water but not at pumping air. If you frequently find air in the pump basket reservoir, you may have a leak. Check particularly around the suction side plumbing. Even a tiny crack can cause air leaks. To check for leaks, use a small container of water and pour it over the most obvious parts of the suction line. Any bubbles clearing from the trap or a change in pump noise indicate a leak.
Additional Tips for Maintaining Your Pool Pump’s Suction
Regular maintenance is key to keeping your pool pump running efficiently. Here are a few additional tips:
1. Clean the Inlet Filter Screen
If the inlet filter screen is clogged, replace the filter. This is often the first step in troubleshooting a suction issue.
2. Inspect Supply Lines for Cracks or Leaks
Check all supply lines and connections for any visible cracks or leaks. Even small cracks can lead to significant issues with suction.
3. Regular Priming and Maintenance
Ensure that the pump is properly primed before use. Regular maintenance, such as cleaning the baskets and checking filters, can prevent many suction issues.
Conclusion
Poor suction from your pool pump can be resolved with some simple checks and fixes. By ensuring that valves are open, clearing debris, verifying filter function, and inspecting for air entrapment or leaks, you can often restore proper suction. Always remember that regular maintenance is key to maintaining an efficient and trouble-free pool pump.
If you find that your pump continues to struggle, it may be time to consider a replacement. Remember, a high-quality pump will provide the best suction and performance.
