The further any Pump has to lift or push water to get it to the surface the less pressure it will be able to make as an end result. More horsepower and Impellers are required as the depth to water increases.
When a pump is pumping water from a level that is below the pump it is called suction head. If the water to be pumped is at a level above the pump, it is positive head. The pump maybe pumping from the base of a tank to a higher level such as an elevated tank or it may be pulling water from a tank that is below the pump. The distance from the center of the pump to the top of the water level would be the foot of head. It takes 2.31 feet to make 1 P.S.I. So if it is 10 feet from the center line of the pump to the water level, you would have about 4.33 P.S.I. of head.
A submersible pump is normally fitted with a float switch. As the water rises, the float switch turns the pump on. When the pump empties the water from the level and the level falls again, the float switch turns the pump off again.
Yes, the internal parts of the pump can rust, and effect water circulation.
So long as there is water coming through the pump when it is running it doesnt matter what the water level in the pool is.
A float switch for a sump pump is used to automatically turn the pump on and off based on the water level in the sump pit. When the water level rises, the float switch triggers the pump to turn on and remove the excess water, helping to prevent flooding. When the water level drops, the float switch shuts off the pump, ensuring that the sump pit does not overflow.
Yes and no. The pump is placed above water level but it is placed there so that in the event that the water level rises, it will be able to pump it out.

When a well pump is running but no water is coming out, it may indicate that the water level in the well has dropped below the pump intake. This can cause the pump to draw in air instead of water, leading to a loss of water flow. In this situation, the pump may continue to run but will not be able to deliver water until the water level in the well is replenished.
yes in order for the pump to work the water has to be over it
A submersible pump is normally fitted with a float switch. As the water rises, the float switch turns the pump on. When the pump empties the water from the level and the level falls again, the float switch turns the pump off again.
If the water pump is driven by the same accessory belt as the power steering pump it could affect the ps pump.
To efficiently drain water from your pool using a pump, follow these steps: Connect a hose to the pump's outlet and place the other end of the hose where you want the water to drain. Submerge the pump in the pool and turn it on. Make sure the pump is set to the appropriate setting for draining water. Monitor the water level in the pool and adjust the pump as needed to drain the desired amount of water. Turn off the pump once the water has been drained to the desired level.
