What are the capabilities of the Simple Pump water well pump?Well depth, capacity, pressure, ease-of use, temperature.What Can a Simple Pump™ Do?How deep can Simple Pump pump from?The hand-operated pump can work from as deep as 350 feet static water level, the motorized pump from 200 feet -- when pumping to ground level and to ambient pressure. These limits are then affected if you are also pumping into a pressurized plumbing system or uphill. (See details.) How much water does it pump?Pumping rates from the Simple Pump vary directly with the frequency and length of strokes of the lever arm. In normal operation, Simple Pump™ delivers up to 5 gallons per minute. How hard is it to pump water?With the Simple Pump, pumping water from normal depths is easy. The lever handle that is standard equipment with our pump system works on common leverage principles and provides a leverage ratio of 3.3:1. The actual force required is dependent on the total length of drop pipe assembly. For a standard installation of 100 feet, it takes approximately 12 pounds of downward force - a child can easily do this. At 200 feet, it takes approximately 24 pounds of downward force. With our 3 foot lever arm, this effort for 200 feet is halved - back to only 12 pounds. "Can the pump really develop enough pressure to fill my pressure tank?"Yes. Simple Pump has been manufactured to very stringent tolerances, which lets the pump develop sufficient pressure to fill a residential pressure or bladder tank. How well does Simple Pump work in freezing temperatures?The Simple Pump was designed similar to a non-freeze hydrant and allows the upper column of water to bleed off to a depth below the frost line. This keeps the pump from freezing. We have many pumps operating 24/7 without difficulty in high-wind, freezing temperatures reaching -30°F. Proper precautions should be taken each fall to ensure that the weep hole has not become obstructed. For hard freeze areas - where it can freeze more than four feet down - you will require a custom weep hole to be drilled in your top drop pipe. This will be done at no additional cost. Do we need a check valve if not for the home, but irrigation?Yes, a check valve is necessary when pumping into any pressurized system. Pressure is required to propel the water, even in drip irrigation. If there is enough pressure to push water out, there is enough pressure to push back when you release the pump lever. This is what the check valve prevents.
