## Description

FloodStop Sink Leak Detector Kit, 3/8" Compression | Automatic Water Shut-Off and Visual/Audible Alarms, Hot & Cold Valves: Water Alarms: desertcart.com: Tools & Home Improvement

Review: Useful for the kitchen sink - Here's a photo of how this looks installed under my kitchen sink. I bought this FloodStop device after my mini water tank heater sprung a leak and made a big mess. The way this works is pretty simple - it shuts off both water supply valves as soon as there is a short circuit in the sensor grid (so it's easy to test by touching a piece of metal). I can see the company has put some thought into the reliability details, for example the logic automatically cycles the valve on and off every month to make sure that the valve doesn't get stuck. When a leak is detected, the alarm beeps and then you can press the button to mute the sound, or press a button to open the valve after the water is dried from the sensor. I'm using Energizer Ultimate Lithium AA batteries for the backup because these will last much longer than alkaline batteries. It took me about 15 minutes to install this, and most of the time spent was to make the excess wire look nice using plastic zip ties.
Review: Works Like a Charm! - Great product that works as stated. Easy to install if you have any DIY experience. One drop of water on the sensor plate activates the alarm and closes the valves. Alarm can be silenced once it goes off. This product can also be used to turn off the water supply to the sink for repairs or when you go on vacation. When you are gone from your home for an extended time, it is better to turn off the main water supply to your house.
