Scheduled Route
Set visits for battery, filter, and diaphragm service before failures generate work orders.
Report

Auto-Flush Fixture FAQ
Can existing manual flush valves be converted to sensor?
In most cases yes — the sensor operator replaces the manual handle on the same valve body, so no rough-in work is required.
Why do sensor fixtures flush when nobody is there?
Usually a sensor range set too wide or a reflective surface across from the fixture. Recalibrating the detection range fixes most phantom flushing.
Do you service multiple buildings on one contract?
Yes. We run scheduled fixture routes across facility portfolios so batteries and diaphragms are replaced before they fail.
