Even a single running toilet in a 20-unit building can waste 6,000 gallons a month — and with master-meter billing, nobody knows which unit it's coming from until the bill arrives. LeakSense gives property managers unit-level visibility, automatic leak alerts, and remote valve shutoff so waste gets caught in hours, not billing cycles.
This walkthrough shows how a master-metered California apartment complex reduced billing disputes, caught a hidden leak within 24 hours, and cut water costs using LeakSense unit-level submetering.
The Challenge: One Bill, Zero Visibility
The property was a 32-unit building in Fresno on a single master meter. Management received one city water bill each month and manually split costs across residents based on occupancy — not actual usage. When the bill spiked $800 one quarter, there was no way to identify which unit was responsible without physically inspecting every unit.
Staff spent three days investigating before finding a continuously running toilet in Unit 14. By then, over 18,000 gallons had been wasted.
The Turning Point: Real-Time Flow Alerts
After installing LeakSense sensors on each unit, the same scenario played out differently. When Unit 14's flow rate stayed elevated for 90 minutes with no shutoff, the system flagged it as a continuous flow event and sent an alert to the property manager's phone.
Maintenance was dispatched the same morning. Total waste: under 400 gallons.
Why This Matters More in California
California properties face growing pressure around water conservation, billing transparency, and submetering compliance for new construction and permitted renovations. Unit-level data makes compliance documentation straightforward — usage is timestamped, trends are logged, and abnormal flow events have a full audit trail.
When residents dispute a bill, the conversation shifts from "we estimated your usage" to "here is your actual usage by day."
What a LeakSense Setup Looks Like
LeakSense installs at the unit level and connects via cellular or WiFi to a centralized property manager dashboard. From one screen you can see:
-
Real-time gallons per unit
-
Usage trends and billing cycle totals
-
Active leak alerts with timestamps
-
Remote valve shutoff for any unit
Installation is handled through a dedicated plumber portal. No per-device app setup, no manual configuration. Once sensors are live, monitoring is automatic.
Results to Expect
Properties using LeakSense typically see faster leak response (hours vs. days), fewer billing disputes because usage is documented rather than estimated, and measurable water cost reductions within the first billing cycle after a leak is caught.
Actual savings depend on baseline fixture conditions, local water rates, and how quickly maintenance responds — but the visibility alone changes how the team operates.
Next Steps: Plan Your California Rollout
If your property is master-metered today, start by answering three questions:
-
How long could a leak run before anyone notices?
-
How many hours per month go into billing disputes and allocations?
-
How much did your water bill increase in the last 12 months?
If any of those answers are uncomfortable, unit-level monitoring pays for itself quickly. Review LeakSense options and request a walkthrough at leaksense.io/product.
