Is a pump installer license different from a well driller license in Wisconsin?
Yes. These are separate credentials issued by the DNR. A Well Driller constructs the well itself. A Pump Installer installs and services the pump and pressure system. Many professionals hold both credentials.
Can a plumber replace a well pump in Wisconsin?
No. Well pump installation and replacement requires a DNR Pump Installer license, even if you hold a plumbing credential from DSPS. The two are regulated by different agencies with different requirements.
Do I need a pump installer license for sump pumps?
No. The DNR Pump Installer license is specifically for water well pumps. Sump pumps, sewage ejector pumps, and other non-well pumps fall under general plumbing or can often be installed without a specific credential.
