What is a common sign that a pool filter is clogged?

A common sign that a pool filter is clogged is a decrease in water flow and pressure. When a filter becomes obstructed, it struggles to pull water through, leading to a reduction in water circulation. This decreased flow can affect the entire pool system, causing a drop in the pressure gauge readings on the filter. Regular monitoring of both flow and pressure is crucial for maintaining effective filtration in a pool. If these indicators show a decline, it typically means that the filter requires cleaning or replacement to restore optimal performance.

On the contrary, increased water temperature may be influenced by other factors like sunlight or heater settings rather than being a direct indicator of filter clogging. Sudden water clarity does not signify a problem with the filter; it may occur when other adjustments have improved water quality. Increased chemical consumption could be associated with various issues in pool chemistry but is not a direct sign of a clogged filter. Thus, recognizing decreased water flow and pressure as a key indicator helps pool operators take timely action to maintain pool conditions effectively.
