Flat-rate quarterly PM for beverage equipment fleets: filter and calibration service, regulator and TDS readings, photo documentation, manager sign-off, and per-machine history for the life of your fleet.
A preventative maintenance visit you can't verify is a line item, not a program. Every JEM PM records water TDS, primary and secondary regulator pressures, parts replaced, machine and rack photos, and the store manager's signature — filed against the machine's serial number, forever. When a warranty question or a quality issue comes up two years later, the history is one search away.
