PlumBuddy Smart Shutoff Valve

Works well, setup took a little longer than expected

The system works well and installation was fairly straightforward. My only minor feedback is that the initial setup took a little longer than expected, but everything has worked perfectly since.

Cat turned on a faucet overnight — PlumBuddy saved our house

I ran downstairs and stepped on wet carpet in my laundry room. My cat had pushed the faucet off the countertop and turned it on — probably rubbing on it. The only reason it didn't flood my wood floors, my kitchen, family room, living room, and hallway is because PlumBuddy shut off the water. I would have walked in this morning with a few inches of water across the main floor of my house. I said to my wife, "the goddamn PlumBuddy saved our house."

Support team has been great

Our ranch has its own well and lots of irrigation valves for the garden & orchard. We feared a major leak going unnoticed and doing some very expensive damage to the well so installed on the main coming off the well. Support team has been great guiding us. Not proved, but it seems like the alarm settings are customizable enough that we can catch a long, high volume leak without a bunch of false alarms.

Peace of mind for the whole house

I installed the Total Protection Pack about a month ago and it has been working perfectly. It's nice knowing the water can shut off automatically if something goes wrong. Definitely worth having installed.

PlumBuddy Smart Shutoff Valve

Provided peace of mind that any leaks will be shut off quickly.

Seems to be a good product. Would like to see more options in app like realtime flow and being able to customize dates so that I could align readings on it with water bill. I’ve had 2 instances where it shut the water off when it didn’t need to, but it was easy to turn back on with the app.
