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.
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.
water pump
yes in order for the pump to work the water has to be over it

If the water pump is driven by the same accessory belt as the power steering pump it could affect the ps pump.
Effect of low water level in the boiler is rapid increase the temperature of the metal tubes, causing a collapse or rupture.

By filling the sump with clean water until the float kicks in and then the pump will start when the correct water level is reached
