With a low yield (low recovery rate) well, you could draw down the water and end up sucking air. Pumping air for any length of time can void our lifetime warranty.
For a well with a low recovery rate but with a tall column of water, the best remedy is to locate the Simple Pump further than usual below the water’s surface.
And if the water does stop flowing, just stop pumping. Wait for your well to fill back up before pumping again.
