Water Leak Detection System Installation Guide: Controller + Motorized Ball Valve + Sensor Integration

Why Passive Detection Isn't Enough

A slow pipe leak behind a wall or under a sink can go unnoticed for days. By the time visible damage appears, you're already looking at flooring replacement, mold remediation, and costly repairs. Traditional leak detectors sound an alarm—but someone still has to physically turn off the water.

The U.S. Solid System goes further: it automatically shuts off your water supply the moment a leak is detected, with no manual intervention required.
