At a glance
Client: Shopping mall operator
Sites: 3 public restrooms in one shopping mall
Kit: iLinks with Flow & Temperature sensors on the toilets
App: evercleanOS
The challenge
A toilet with a faulty flush valve can run into the bowl for hours. In a closed mall nobody hears it, and the water is lost until the next cleaning round or the next bill.
What we installed
- iLink — On the toilets of 3 public restrooms
- Flow & Temperature — Flow per toilet, around the clock
- Water Intelligence Platform — Alarms and usage history per toilet
Alarms that did the work
- Abnormal flow · Sent automatically on a Sunday, outside business hours
What the data showed
One toilet, 500 litres in 8 hours
Flow data showed which toilet was running continuously and how much it had lost.
Who’s working on Sunday?
The flow appeared while the mall was closed, so it could only be a fault, not a visitor.
Root cause found on site
The facility manager traced the loss to the water pressure and the toilet’s flush valve.
Results
- Leak located: 1 toilet — Out of 3 monitored restrooms
- Water lost before the fix: 500 L — In 8 hours
- Cause identified: flush valve and pressure — Found on site by the facility manager
