Total Control Over Your Water Supply, Instantly.
Protect your property from the devastating effects of water damage with the AJAX WaterStop, a smart, wireless water shutoff valve. Integrated into your AJAX security system, the WaterStop gives you the power to shut off your water supply remotely from anywhere in the world using the Ajax app. In the event of a leak detected by an AJAX LeaksProtect sensor, the WaterStop can react automatically in as little as 5 seconds, minimizing potential damage and giving you ultimate peace of mind.
Key Features:
- Rapid Emergency Shutoff: The powerful electric actuator can shut off the water flow in just 5-7 seconds, whether commanded manually or triggered by an automated scenario.
- Powerful & Reliable: With a torque of up to 8.5 N·m, the WaterStop can turn even a stuck valve, ensuring reliable operation when you need it most.
- Remote & Automated Control: Use the Ajax app to check the status and control the valve from anywhere. Create scenarios that automatically shut off the water when a LeaksProtect sensor or a third-party detector is triggered.
- Long-Range & Secure Communication: Featuring Jeweller radio technology, the WaterStop maintains a secure, encrypted connection with the Ajax hub at a distance of up to 1,100 meters.
- Long Battery Life: Operates for up to 3 years on its pre-installed batteries, ensuring continuous protection even during power outages.
- Easy Installation: The electric actuator can be mounted onto the included high-quality RuB valve without any special tools, in one of four possible positions.
- Manual Override: A built-in lever allows for manual water shutoff in emergencies, providing a failsafe option that doesn't require power or a hub connection.
Advanced Automation for Complete Protection
The true power of the WaterStop is realized when it's part of a comprehensive Ajax security system. Configure simple automation scenarios that link the WaterStop to one or more LeaksProtect sensors. The moment moisture is detected, a command is sent to the WaterStop to immediately cut off the water supply, preventing a minor leak from becoming a major disaster. The system keeps you informed with instant, informative notifications directly to your smartphone.

It worked! Apple Care was added to my device when I received it!
Style Name: MacBook Pro 14" (M4 Pro/M4 Max), Configuration: 3 years
I purchased an MacBook and AppleCare+ at the same time. A day/two after the purchase I received an email from Amazon that the AppleCare+ was in software and go to digital download. When I downloaded it was just the agreement. Then I started reading all the negative reviews on nightmare experience with Amazon and AppleCare+ not being added. I was very nervous and mentally prepare for the nightmare that lie ahead which having to call Amazon multiple times and then having to call Apple multiple times. To my surprise, right after Amazon delivered the MacBook (I got notification your item was delivered) I got another email from Amazon that AppleCare+ was added the laptop with agreement number and serial number of the laptop I received. I checked Apple's coverage site and sure enough Apple site showed AppleCare+ coverage tied the MacBook. I didn't even open the box or turn it on and see the AppleCare+ coverage. Hopefully this gives some insight to future buyers of AppleCare+ from Amazon!!!

DO NOT PURCHASE APPLECARE+ THROUGH AMAZON (Please read before making a decision)
Style Name: MacBook Air 13" (M4), Configuration: 3 years
I rarely write reviews like this, but DO NOT PURCHASE APPLECARE+ THROUGH AMAZON.
Just over a month ago, I purchased an Apple MacBook Air (m4) with AppleCare+. The AppleCare+ wasn't populating on the laptop, so after calls with Apple Support and Apple Agreement Administration, they found that AMAZON sent them the approved agreement with the device serial number then abruptly canceled it the following day. This happened over a month ago, and I was not notified nor have I received a refund.
I would not have known it was canceled if not for Apple Support and Apple Agreement Administration.
The only recourse is to receive a refund from Amazon--which is NOT automatic, I am fighting for this--and purchase AppleCare+ directly through Apple. Had all this taken place after the 60-days purchasing the MacBook Air (I'm currently one week short of this deadline), then I would be SOL on being able to cover my device.
PURCHASE AT YOUR OWN DISCRETION/RISK AND CHECK THAT APPLECARE+ IS APPROVED AND ACTIVE ON YOUR DEVICE. Otherwise, play it safe and activate directly through Apple.

Worked fine for me 🙌🏽
Style Name: MacBook Air 13" (M4), Configuration: 3 years
I read a lot of comments that said there was an issue with their purchase of AppleCare+, I did not have any of those experiences. AppleCare+ was on the laptop (MacBook Air, 13-inch 2025) automatically. I received an email with my confirmation of AppleCare+ coverage, along with my agreement number, product serial number and expiration date. There was nothing I needed to do on my end, because as I said it had already been added to my computer and attached to my iCloud account. — I hate that there are so many bad experiences and hope everything works out for anyone experiencing a nightmare but I can only recommend based on my experience, 10/10.

Fantastic product
Size: 8 Fl Oz (Pack of 1)
Works Great, at first didn't believe all the reviews, I've bought 5 chainsaws from one season to the next. After each winter couldn't get them to start. Followed the instructions to flush and let sit for a few days. Every one started and ran great. Hands down, this is a remarkable product for cleaning out blocked fuel systems from sitting all winter would recommend it for all 2 cycle engines and use the stable blend for winter as well as anytime use to prevent fuel spoilage.
