DIY Automatic Water Leak Detection & Shut-Off Starter Kit, Valve Operator, Wireless Valve Controller, (3) Leak Sensors, Hub

the valve controller i received is look like used before , there is scratch in the back side , advise me how i can share with you the photo

Simple setup, works as advertised. Purchased after washing machine failure. This was super easy to setup and works great. Valve response is pretty quick. Alerts you on your phone and closes the valve automatically.

This is a complete and self-contained system to detect leaks, notify you, and shut off your water main. It comes with three leak detector sensors and each already has the necessary batteries installed. They can be bought separately in sets of three. Installation is a bit laborious only insofar as there are a number of distinct steps, though no one of which is very hard to do. Only tools needed were a cordless drill with a Phillips head driver bit, a Phillips head screwdriver and a crescent wrench. You will need a WiFi router and you will need to create a dedicated 2.4GHz channel for it. You will also need to connect the YoLink WiFi hub by Ethernet cable to your WiFi router and also to wall power. This will be the "brain" and respond to water leaks detected by your sensors to notify you and shut off your water main. This is designed for a quarter-turn 1" ball valve. If your water main is not equipped with one you are SOL. The valve operator comes with a couple of sets of adapters, clamps and ring couplers so you have options to best fit the mechanical operator to your water main's ball valve and its location. This will need to be connected to an electronic controller which is mounted to nearby wall (wood or drywall screws are included) which in turn will need to be connected to wall power. The leak sensors then need to be added to the system, named and then put in place. Each one has a pair of steel electrodes on bottom and on top. Apparently, they can be triggered by as little as 0.01" (0.25 mm) of moisture. I could test trigger one by licking the pad of my thumb and touching it to the electrodes. The valve operator automatically shut off the water when I tested a sensor on the third floor of my house; the hub is on the main/second floor and the water main is in the basement/first floor. You will need to be able to download and use a smartphone app to link all these devices together and personalize any settings such as notification by email, text, banners, sound, etc. Just let you know, or also automatically shut off the water? Also, I recommend scanning the QR codes in the enclosed Quick Start instructions for detailed User Instructions. Definitely worth it. Overall, I am happy with this system and look forward to seeing how well it works over time. It is complete and installation requires a number of distinct steps (details above). A few things that don't leap off the page: you'll need to be comfortable with downloading and using a smartphone app, setting up a 2.4 GHz channel on your router and this only works with a quarter-turn ball valve control on your water main. You'll need to connect a hub directly to your WiFi router and to wall power, and the valve controller setup will need to be close to wall power as well as close to your water main shut-off valve.

I purchased this automatic water shutoff valve and water sensors for a rental property after dealing with a major issue caused by renters exceeding the allowed number of occupants and overflowing the septic system. I wanted an early warning system that could alert me if water was present in critical areas like the utility room or around bathroom sinks before serious damage occurred. Setup was straightforward. The sensors were easy to install and quickly connected to the hub, and they’ve maintained a solid connection throughout the house. One concern I had was whether the shutoff valve would work properly, since the main water valve has hard water buildup and visible rust. I was pleasantly surprised—it worked perfectly and had no problem fully shutting off the water when triggered. The system has given me real peace of mind, especially for a rental where you can’t always control how the home is used. I’ve been so impressed with the performance and reliability that I ended up buying the same system for my own house as well. So far, everything has worked exactly as advertised. Highly recommended for homeowners and landlords who want added protection against water damage.

I am impressed with the quality. Instructions could have been easier for the communication setup.
