Checking for Air Leaks in Pool Pump
When you’re dealing with a pool pump surge or pump surging, air leaks are often the main culprits.
A pool pump that’s struggling with air leaks won’t maintain a steady flow, leading to the infuriating pulsing and surging behavior. To fix this, start by inspecting the connections and seals around your pool pump.
Typically the pump eventually will prime, but not without heat being generated on the pump and fittings. Over time this heat creates vacuum leaks on the threaded inlet and the pump acquires another obstacle to overcome
Pay close attention to the pool pump’s strainer cover. The O-ring inside can wear out over time, and when it does, it lets in the air, causing the pump to surge. Another spot to investigate is the plumbing fittings. An air leak in any of the pipes leading to the pump will cause the same surging issue. Use a soapy water solution to check for bubbles around joins and fittings, which are telltale signs of air leaks.
Next, check the pump’s lid and ensure it’s sealed tightly. A loose or cracked pump lid can be a significant source of leaks contributing to air entering the system. Skimmer baskets can also be a source of air leaks if they’re not packed properly or have gaps.
Seal around the pool pump’s drain plugs as well; these can degrade and loosen over time, allowing air into the pump. Lastly, don’t forget to inspect the valves. Old and worn valves can leak air, hampering the efficiency of the pool pump, and causing further surging issues.
Remember, fixing air leaks in your pool pump not only helps stop surging but also improves the overall efficiency and longevity of your pump. Keeping your pool pump in top condition ensures a cleaner and more enjoyable pool experience. Dive into these checks to keep your pool pump operating smoothly.
