STOP FLOOD DAMAGE 

BEFORE IT EVER STARTS.

Mainline FloodStop is a point-of-use leak detection device that automatically shuts off the water supply to the appliance the moment a leak is detected.  Once water is detected, the motorized ball valves close and sound an alarm.  FloodStop devices limit potentially devastating flood damage, allowing the plumber, builder, and homeowner to have peace-of-mind knowing no flood caused by an appliance will go unnoticed.  

MAINTENANCE FREE

Lead-free, CNC machined, open motorized ball valves close every 30 days for regular self-maintenance.

POWER BACK-UP

FloodStop comes with an AC power adapter and optional battery backup, to keep your home protected whether the power is on or not.

15-MINUTE INSTALL

Attach valves, mount unit, set and forget. FloodStop does the rest.
