Registration for unlicensed water conditioning installer

Anyone performing water conditioning work in Minnesota must be licensed by our agency or be a registered unlicensed plumber or water conditioning installer. The fee for an initial registration as a registered unlicensed water conditioning installer is $14. 

Registrations expire June 30 and must be renewed annually. A $5 late fee is assessed on all late registrations.

A registered unlicensed water conditioning installer can take the journeyworker water conditioning license exam after completing 875 hours of practical water conditioning installing, servicing or training experience as a registered unlicensed water conditioning installer employed by a licensed plumbing contractor or water conditioning contractor. An individual may receive credit for up to 100 hours of work experience gained prior to becoming registered as long as the work experience occurred within 12 months of the individual becoming registered.

All water conditioning work performed by an unlicensed water conditioning installer must be performed under the direct on-site supervision of  a licensed journey worker,  master plumber, restricted journey worker, restricted master plumber, licensed journey worker or master water conditioning worker.
