Why does my swimming pool pressure drop after a few minutes?

Several reasons could cause your swimming pool pressure to drop after a few minutes. Here are some potential issues:

1. Clogged Filter: A dirty or clogged filter can restrict water flow and cause the pressure to drop. Check the filter and clean it if necessary.

2. Air Leak: An air leak in the pool system, such as a loose pipe connection or a cracked hose, can allow air to enter the lines and cause the pressure to drop. Inspect all the connections and hoses for leaks and tighten or replace any loose or damaged components.

3. Faulty Pressure Gauge: The pressure gauge itself could be faulty, giving inaccurate readings. Try tapping on the gauge to see if the needle moves. If it doesn't, the gauge might need to be replaced.

4. Low Water Level: If the water level in your pool drops below the recommended level, the pump will have difficulty drawing in enough water, leading to a drop in pressure. Ensure the water level is maintained at the proper level.

5. Pump Problems: If the pool pump is malfunctioning or not working correctly, it may not be able to generate sufficient pressure. Check the pump to ensure it is operating correctly, and if necessary, have it serviced or repaired.

6. Blocked Impeller: The impeller, which is the rotating part of the pump, can become blocked by debris or leaves, causing the pressure to drop. Inspect the pump impeller and clean it if necessary.

7. Incorrect Valve Positions: If any valves in the pool system are not positioned correctly, it can affect water flow and pressure. Check the valves to ensure they are open and positioned properly.

8. Overloaded Filter: In some cases, the filter may become overloaded with dirt and debris, leading to a drop in pressure. Consider cleaning the filter more frequently to prevent this issue.

If you are unable to identify and fix the cause of the pressure drop самостоятельно, it is recommended to consult with a professional pool technician for assistance.
