Considering that the pump is usually at the end of the deep well, there are no elevation restrictions due to vacuum lift, as well as deep wells can reduce the groundwater over 50 feet.

On the bottom of the wellpoint there is a 2 foot long display and valve, water jets out of this shutoff and creates a hole right into which the wellpoint pipeline can be lowered. This opening is typically made a bigger size (for instance 10 inches) to allow for a rugged sand backfill to help filter the water (excavator).
