Don't possibly know why you could be loosing pressure on the pool. However you may be loosing pressure in the line to the pool from the filter. If you are also loosing suction then :
there is not enough water in the pool and the skimmer is sicking air.
bad pump seal
loose pump lid
bad o-ring seal at pump lid
loose fittings in and out of the pump. that is the piece of equip. that has the motor attached. The filter is the large tank. The pool is the vessel that is holding all the water.
You can also lose pressure if your skimmer and your pump baskets are filled with debris, kink in the hoses, or your filter needs to be cleaned, or filter sand or cartridge needs replaced.
You also may be thinking of pressure as in the force of the water coming out of the return jets. If this is the case, then your filter has become dirty and the water can't pass thru it very well. Clean your filter.
If I was to make a guess, I would say if you have not tried backwashing the filter, then it is time to change the filter media inside the filter.
You might be pulling air from the skimmer or there is a leak some place within your pump on the suction side
it is because there are not many people who actually use above ground pools I recommend getting a underground pool so then it wont leak
A dirty or blocked filter
Usually the pressure gauge on your pool equipment indicates how much pressure there is before the filter. as the pressure goes up it indicates that the filter is getting blocked and needs a backwash or cleaning. while the pressure is low the filter does not need cleaning.
Leaves in the impeller of your pump.
yes it will shut down. the low pressure switch will shut it down.
Hurricanes are low pressure systems.
No, a cyclone is a large, rotating low-pressure system that occurs in the air. A whirlpool is a vortex that happens in water.
A fluid will move from high pressure to low pressure.
Breeze is a slight wind that is usually caused by either a mountain or pool of water. Wind refers to air moving from a high pressure to low pressure.
High pressure, and low temperature.High pressure, and low temperature.High pressure, and low temperature.High pressure, and low temperature.
It is low pressure
No, it blows into low pressure areas. Air moves from areas of high pressure to low pressure.
Low Pressure, A Low Pressure Area allows clouds to form, as a result, you can get a storm from a low pressure area.A High Pressure Area is the exact opposite, it doesn't allow clouds to form, you can get sunny weather from this kind of system.
In a low pressure system, the air pressure, which is the force with which the air presses down, is lower than what it normally is. Hence, it is called a low-pressure system.
