Why Water & Smart Toilet Monitoring

Most buildings spend more on water than heat.

Water costs have surged across every major U.S. market over the last five years and the trend is going up.

The Problem

51% of toilet water is lost to running toilets — not flushing.

Toilets account for roughly 25% of a building's total water use, meaning leaks alone can represent 12–20% of your entire water bill.

The Money Pit
Full constant flow

A single undetected running toilet at full flow can cost up to $40,000 per year. Vacant units are especially at risk.

2 years of R&D. Zero plumbing. Zero WiFi. Zero disruption.

1
Snap onto the toilet hose

2
Temperature differential detection
Our invention: we compare the hose temperature to ambient air temperature to detect continuous water flow — no flow meters, no cutting pipes, no WiFi needed.
3
Instant alerts via app, text, or email
Management is notified the moment a leak is detected — with the exact unit and toilet location. 10-year battery life, zero maintenance.
