Few things are more frustrating for pool owners than noticing the pump isn’t doing its job. A drop in pressure can leave your water cloudy, make cleaning less effective, and even put stress on your equipment. While there are several possible causes, plumbing issues are often the culprit. The good news? With a little troubleshooting, you can figure out what’s going wrong and prevent bigger headaches down the road.
Common Reasons Your Pool Pump Is Losing Pressure
1. Air Leaks in the Suction Line
If your pool pump is pulling in air instead of water, it won’t be able to maintain proper pressure. Air leaks often happen in the suction line, at pump fittings, or around the pump lid’s O-ring. A good first step is to check for loose connections and make sure the lid is sealed tightly.
2. Clogged Skimmer or Pump Basket
It sounds simple, but clogged baskets are one of the most common causes of pressure issues. When debris blocks the water flow, your pump has to work harder, and pressure drops. Cleaning out your skimmer and pump basket regularly helps keep things running smoothly.
3. Dirty or Blocked Pool Filter
If your pool filter is overdue for a cleaning or replacement, water won’t pass through as it should. This creates extra resistance and leads to low pressure. Check your filter for dirt, debris, or buildup, and backwash or clean it as recommended by the manufacturer.
4. Underground Plumbing Problems
Sometimes, the issue goes deeper—literally. Underground leaks, cracked pipes, or other hidden plumbing issues can reduce the amount of water reaching your pump. These problems aren’t always easy to spot, but they can cause serious long-term damage if ignored.

5. Worn-Out Pump Parts
Like any mechanical system, your pool pump has parts that wear out over time. A failing impeller, bad seals, or damaged gaskets can all lead to reduced pressure. If you’ve ruled out simple causes, it may be time to have a professional inspect the pump itself.
How to Prevent Pressure Problems
-
Stay on top of maintenance – Clean baskets, backwash filters, and inspect pump parts regularly.
-
Check water levels – Low water levels can pull in air and reduce efficiency.
-
Schedule seasonal inspections – A professional check-up before peak swimming season can catch small problems before they turn into big ones.
Final Thoughts
A pool pump that’s losing pressure doesn’t just affect water clarity—it can also shorten the life of your equipment. Whether the issue is as simple as a clogged filter or as complex as underground plumbing damage, staying proactive will keep your pool sparkling and your system working efficiently.
