Determine whether pump installation requires a separate license from well drilling in a given state, using the multi-state variation in licensing structure

Steps
Recognize there is no national standard — roughly a dozen-plus states maintain a pump installer license fully distinct from the driller license and from general plumbing credentials
Example — Connecticut: issues separate W-1 (driller) and W-2 (pump installer) license classes
Example — New Hampshire: requires a distinct pump installer license (NH DES Water Well Board) separate from the well contractor license
Example — Indiana: issues a single DNR license card but explicitly designates whether the holder is licensed as driller, pump installer, or both
Example — New York: individuals performing both drilling and pump installation/servicing must be certified for both activities separately, not just one
Known gotchas
Assuming a driller's license automatically covers pump work (or vice versa) is a common and state-dependent mistake — always check the specific state's structure before assuming scope
Some states fold pump installation entirely into the general plumbing license instead of a groundwater-specific one — 'no separate pump license' can mean 'covered by driller license' or 'covered by plumbing license,' which are very different answers
License card format varies (single combined card with designations vs. two entirely separate license numbers) — verification lookups may need to check both fields
