The FloodStopWater Sensor, Wired is a highly sensitive, 3-foot wired water detection sensor designed to integrate with FloodStop leak detection systems. It features adjustable sensitivity, unlimited daisy-chaining capability for extended coverage, and detects even the smallest water drops to trigger valve closure, providing scalable, customizable flood protection for your home or office.

## Description

The FloodStop point-of-use leak detection devices 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.

Review: Works fine - Works as advertised. Easy to install.
Review: Expanding my Floodstop to protect my house! - I've had a floodstop for years on my washing machine, and its been very reliable. At one point I had a question, and was able to speak directly to the owner/designer of the floodstop system; and he gave me advice and offered to replace a gear part for free if needed. After finishing the basement, and putting new flooring on the main floor, I decided I needed whole house flood protection. I used a floodstop water heater valve & controller, and put the valve on the main water line in my house; and when I finished the basement I ran wires anywhere in the house there was a water source. Then I'm putting these sensors in every bathroom, the sump, the dishwasher, water heater, and the refrigerator, so if I get a leak it will shut off the water automatically and avoid flood damage. I also have a sewage pump, and I put in a float valve in the sump so the floodstop will shut off the water if the pump fails so I don't get septic backup. I chose floodstop because it was inexpensive, robust and simple. The newer controller has battery backup and runs a test cycle monthly. Now if only I could get a discount on my homeowners insurance! The floodstop has everything I need

### ⭐⭐⭐⭐⭐ Great addon for Aqara Water Leak Sensor
*by M***K on August 10, 2024*

With little modification to the wire harness, Im using this with my Aqara Water Leak Sensors. I have several of them and use the FloodStop Leak Detector Water Sensor on all of them. They work as expected.
