A plumber is well-suited for shallow-well jet pump installations and for work inside the home. However, plumbers focus on interior plumbing, not down-well equipment, and often lack the specialized tools for deep wells.

For pump installation outside the home, a local well pump pro or licensed pump installer is the safer, more complete choice.
