Challenge
“Fine” can be temporary
This 15-unit Manhattan rental, managed by Big Apple Management, was running below the average for similar properties — until a single toilet in unit 5E began to run and daily water use spiked to nearly 4x normal, around 6,575 gallons a day.
Solution
How Runwise caught it
Smart Toilet Monitoring flagged the spike immediately and traced it to unit 5E, where a broken flush handle had left the flapper loose in the tank. The plumber replaced the handle and flapper, and usage returned to normal within days.
Results
Monitoring as insurance
Left unchecked, that one running toilet was on pace to cost about $30,000 a year — in a building that looked perfectly efficient the week before. Even normal buildings are one failure away from a five-figure leak, and Runwise is what catches it in days instead of months.
