GENERAL INFORMATION
NOTICE:
Model Number of your pump is located on the
pump shell. Record this number and keep in a safe place for
future reference in the event service is needed.
The most important things you should know about your well
are: (1) its total depth; (2) depth to water; (3) draw down
water level.
1. The well
total depth
is the distance from the ground
level to the well bottom.
2.
Depth to water
is measured from the ground level to the
water level in the well when the pump is not running.
3.
Draw down water level
is the distance from ground
level to the water level while water is being pumped. In
most wells, the water level drops when water is being
pumped.
Usually you can obtain this information from your well
driller. Enter it in box at right.

*Pumping depth in feet is the maximum distance to water from ground level. This maximum distance (drawdown water level) occurs while pump is operating.
In most cases, when pump is not running, the water level will rise to a higher point in the well.
