Automatic Hot Water Heater Shut Off System and Water Leak Alarm and Detector, Quality Design and Material, Easy Installation, Compatible with Most Lever Action Ball Valves

I purchased this as an open-box item for around $70, and it was in perfect condition—never even used! Setup was straightforward, though I had to use a trick I often apply to Wi-Fi smart bulbs to get the smart module connected. If you're struggling to connect it to Wi-Fi, don’t blame the product—it’s likely due to your phone or network setup. The smart module only supports 2.4 GHz Wi-Fi, but modern smartphones no longer allow you to manually select 2.4 GHz, and many routers combine 2.4 GHz and 5 GHz into a single network name. To work around this, use your phone’s hotspot and set it to broadcast a 2.4 GHz-only signal with the same Wi-Fi name and password as your home network. Then: 1. Turn off your home Wi-Fi. 2. Use another device (tablet, old phone, etc.) to connect to the 2.4 GHz hotspot. 3. On the device connected to the hotspot, open the RCA Water Shut-Off app and navigate to Gear > Devices > Wi-Fi Settings. 4. Enter your Wi-Fi password and click Search to connect. This method worked perfectly for me. The issue isn’t with the app—it’s just that these modules aren’t compatible with 5 GHz Wi-Fi. Once set up, everything runs smoothly. Great product overall!

The servo and the controller work fine, but the app and the Smart module do not work. This is a common complaint. I don’t know for sure but I think this is an item that was made and sold years ago and has not been kept up to date. The unit works fine on its own without the app and smart controller but it won’t notify you other than the alarm on it. Customer support is non- existent. I’ve contacted Amazon and they contacted the vendor- crickets-no response!! The rest of the hardware seems to be well made and easy to install- but the info regarding the app and smart controller is not correct and I believe outdated.

This is the second review I will try to post. Amazon said my first did not meet their rules on posting reviews. The only reason I gave one star is because I tried everything the manufacturer said to do to get the smart module to pair with wifi. Tried to contact the company on their website, no such website, I checked my spelling to make sure I typed the right address. The only reason I bought this brand was for the smart technology. The item will work just fine without wifi, but that is not the point. I bought it for that reason and there is no way to contact them. Not even a phone number.

Product was easy to install and works well. In some cases this can lower your Home owners policy costs. Nice peace of mind since my Water heater is inside the house with expensive hardwood floors. Includes WIFI adapter that will alert you on your cell phone if there is a leak and automatically turn of the water supply. Water can also be shut on and off remotely. Turn it off before you leave and turn it on a few hours before you arrive from vacation.

I bought this for a vacation home so if my hot water heater goes, it won’t be catastrophic. It was easier to install than expected. Took me about a half hour. No tools needed. Installing the app was also straightforward. And it worked when tested. No complaints here and I’m happy I purchased it.

I bought this for our hot water heater in the attic. I chose this one because the valve actuator is installed over your existing ball valve. The others require a new valve to be installed with built in actuator. Installation was fast and easy. I deducted 1 star because the app for your phone does not work. There are multiple comments on the App Store about it having not worked in a long time. I’m not expecting to be able to use that functionality. You don’t have to use this part of the kit so it’s not a deal breaker. I do feel the price should reflect a reduction based on that shortcoming. Another note, there is no battery option with this unit. You must have an outlet close by. The listing mentions “no wiring required” but I’m not sure what they’re talking about since you have to plug it in. I plan to add an outlet in the attic for it. Currently using a drop cord. I did not deduct a star for this since the listing does not say there is a battery option but I do feel it was implied. Overall, I do recommend and feel it will work as expected in an emergency.

Easy to install ans it worked when I tested it.

I purchased this item because of the fact it works over a existing ball valve and i i didn't want to shut my system down installing a shut off with a built in valve. I tested it with the test button and also by trickling some water on the sensor and it worked perfectly. The only problem is the app does not work no matter how i try and there is nowhere to get any technical help. Absolutely nowhere . Since i got it half price i will keep it if i didn't amazon would get it back.
