How to Clear a Pool Filter of Obstruction
- 1). Check the skimmer basket and the pump basket. These two areas quickly become clogged with leaves, dirt and whatever debris that is in the pool. Clear out any debris in the baskets and see if that fixes the problem.
- 2). Take note of the pressure gauge number on the pool filter. Check to see if it has risen by more than 8 points since you last cleaned the filter. If the pressure gauge number has risen at least that much, the obstruction is most likely due to dirt in the filter.
- 3). Check the hose connections for leaks. Sometimes the obstruction isn't an actual physical obstruction that requires clearing; it may be a condition that needs to be corrected. If the hoses are leaking, that means water is coming out and air is getting into the filter system. Pool filters do not function properly when air gets into the system. Tighten the connections to prevent air from getting in.
- 4). Examine the pool water level. Another source of air getting into the system is through the skimmer. If the water level is lower than the mid-height of the skimmer faceplate, air can be drawn into the filter through the skimmer outlet.
- 5). Feel the water-return flow. If after cleaning the filter and removing the debris, the water-return flow is still weak, the problem may be in the pool pump itself. Listen for a high-pitched whine, a grinding noise or even excessive vibration in the pool pump. Any of these symptoms point to pool motor or impeller problems. A motor in need of lubrication or bearings will make a high-pitched wine or grinding sound, while an imbalanced impeller will cause excessive vibration and diminished water-return flow.
