Residential Smart Water Sensors
Catch Leaks Early Before They Turn Into Costly Home Damage
A small leak can quickly become damaged floors, ruined drywall, mould, and a major insurance headache. Grand Alarms smart water sensors help detect water early, send instant alerts to your phone, and can trigger automatic water shut-off to help protect your home before the damage spreads.
Smart Water Protection Built for the Way Homes Actually Leak
A low-profile leak detector built for tight spaces where water tends to collect first. It can trigger instant alerts and provide on-device audible and visual warnings when moisture is detected.
A smart flood sensor with a remote probe designed for problem spots like under sinks, behind appliances, and around water heaters, where early detection matters most.
A motorized shut-off device that works with your system to automatically close the main water supply when a leak is detected, helping stop the problem before it spreads.

Finding the Leak Is Good. Stopping the Water Is Better
