If the pool water level gets too low, the pump will suck in air, leading to low water pressure in the filter system. To fix this, check the skimmer opening in the pool. If the water is below the skimmer, that’s why you have a low pressure in the pool filter. You’ll need to top up the pool with water to the ideal level.

There is an air leak (suction leak) in the underground pipe between the weir (skimmer box) and the pump, causing the swimming pool pump to lose pressure. The connector fitting at the weir or the pump could be loose or perished. The shaft seal in the pump could be cracked and leaking. The filter sand could be clogged.
