How fast can a Submersible pump drain pool?

The speed at which a submersible pump can drain a pool depends on several factors, including:

1. Pump Capacity: The capacity of the pump, measured in gallons per minute (GPM), determines how much water it can move per minute. Higher capacity pumps can drain pools faster.

2. Pool Size: The size of the pool, in terms of its volume, affects the amount of water that needs to be pumped out. Larger pools take longer to drain than smaller pools.

3. Hose Diameter: The diameter of the hose connected to the pump also impacts the drainage speed. Wider hoses allow for faster water flow, resulting in quicker drainage.

4. Vertical Lift: If the pump is positioned below the water level, it has to work against gravity to lift the water up. The vertical lift, or the height difference between the water level and the pump outlet, can affect the pumping speed.

5. Electrical Supply: The electrical supply available to the pump determines the power it can draw. Pumps with higher power ratings can operate faster and more efficiently.

Considering these factors, a typical submersible pump with a capacity of 1,500 GPM can drain a 10,000-gallon pool in approximately 7 hours. However, this timeframe can vary based on the specific conditions and limitations mentioned above.
