Leak Controller™
from AXEON Water Technologies

Upon sensing moisture, Leak Detectors will engage the shut-off valve and sound an alarm. The water source is cut off, stopping the leak while the alarm continues to sound until the valve is manually reset. By preventing continuous water flow, mold and property damage are restricted and user... [See More]
