Because the pump is typically at the end of the deep well, there are no height restrictions as a result of vacuum lift, and deep wells can reduce the groundwater over 50 feet.

Under of the wellpoint there is a 2 foot long display and also shutoff, water jets out of this shutoff and also creates a hole into which the wellpoint pipe can be decreased.
