System Calc

Use the FloJak Slide Calculator to Estimate the Ideal Pump Kit Length for sizing submersible well pumps and jet well pumps. There are two inputs for the well pump calculator...Static Water Level and Well Depth. The ideal well pump sizing for your system is somewhere in between...but as close to the bottom as can afford.

Recommended Pump Kit Length
Note: The “Estimate” above is in 50 foot increments (just like out kits). It is advisable to install your pump so that the foot-valve (water inlet end) is as far below static as possible to protect from draught and seasonal water table fluctuation. Doing so will also provide additional water reserve in the well while drawing from deeper, cleaner water sources. Stay 10 to 20 feet off the bottom to avoid pumping silt.
