Prevent water damage from failed Dishwasher, Toilet, R/O and Supply Line:

Dishwasher leaks are often small and go unnoticed until significant damage is finally discovered. Such a leak will continue to collect under the Dishwasher and then seep between the kitchen flooring and sub-flooring. The damage often goes undetected until the floor is visually buckled or warped, at which time the damage and cost to replace is extensive.

Toilet's overflow, R/O systems leak and supply lines rupture causing significant property damage. The actual event can begin and then go unnoticed for hours and even days.

FloodStop (FS 3/8-C) automatically shuts off the water supply to the Dishwasher, Toilet or R/O whether caused by a small continuous leak, broken component/fitting, leaking seal, overflow or a ruptured supply line. Powered by AC/DC Adaptor/Transformer or Batteries. Output contact available, which allows the Controller to connect with Alarm, Home Automation or Auto-Dialer systems if desired. Easily installed in ten minutes.
