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.

Peace of mind

Installed and worked immediately. Warned up about a leak on water softener. Still a lot of kinks to work out. But definitely has potential to be really good once they figure it out.

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."

Piece of mind for leak detection and shut-off

The app had some issues but the team was on it and got the app back up and working. I have had no issues since that time and can not say enough about the piece of mind that having the valve and sensors give.

High-quality, Well-Engineered Product and System

I installed my first Plumbuddy valve and 3 sensors a month ago in my primary rssidence, and just added 3 additional sensors this week. First, the Plumbuddy valve is high quality brass, versus the competition being cheaper plastic. The valve was pretty simple to install on my Pex-B piping. I installed the valve in my encapsulated crawlspace, where I already had a power receptacle closeby to plug in the valve. I did not encounter any problems during the valve installation or setup of the devices in the App. Installation took a little over an hour and a half - starting from scratch getting the valve installed, App downloaded / my account set up, and all devices connected; the job went quicker than I expected, which was positive. I have been very happy with both the product itself, and the App interface. It is clean, well designed, and functions well.

Overall, so far so good.

As a plumbing business owner. PlumBuddy is easy to install and operate. App interface is user friendly as well. Having to split my internet network to 2.4ghz was a little annoying. Once that's figured out. No issues at all. I would suggest supplying the unions for installation to save the homeowner or plumber a trip to acquire these. Or at least be clear they are not provided.

Best wifi enabled system in you want a smart valve plus point of risk sensors

I installed a Plumbuddy smart valve (with the help of a plumber) and 13 remote leak detectors. When u attempt to pair a plumbuddy device and pairing fails, do not press the "retry" button, in my experience that wont work. Remove the backup battery from the Plumbuddy device and incase of the valve wait for the unit to fully discharge and stop flashing (about 5 days). Turn off bluetooth on your phone, delete the plumbuddy app, and power cycle your phone. Enable bluetooth, make sure your phone is set to the 2.4Ghz signal from your router, and reinstall the plumbuddy app. Then re attempt pairing, this consistently works in my experience. The system has been running perfectly and performs as advertised.. The system is still function through Power outages and router signal loss. i filled up a bucket of water from a faucet insiide the house and plumbuddy detected it an shut off the water which was easily restored with the plumbuddy phone app or by pushing the green button on the plumbuddy valve. The app is pretty self explanatory and i like the fact that i can now monitor my daily household water useage.

Found some small leaks in vacation rental property

Great customer service. Seems like a start-up, and I think it's a great company with a great product. We're refining our use of this for our Short Term Rental to be sure the property is always ready for guests. We had a problem with one of the water sensors and it was cheerfully replaced.

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

Great Product and Peace of Mind for Homeowners! I recently installed PlumBuddy and have been very impressed with the system. Having the ability to monitor water usage, detect potential leaks, and automatically shut off the water provides tremendous peace of mind, especially when you're away from home. Pro tip: I would highly recommend for anyone setting up PlumBuddy: If your router allows you to temporarily pause the 5 GHz band and broadcast only 2.4 GHz, do it during installation! This makes connecting the devices much easier and helps avoid unnecessary frustration. Once everything is connected, you can turn 5 GHz back on. I use an Eero mesh system, and this made a big difference in getting everything connected. The app is easy to navigate, and I really like being able to monitor my home's water usage and control the main water valve remotely. Overall, PlumBuddy is a great investment for protecting your home from costly water damage. I would definitely recommend it to anyone looking for a smart water monitoring and leak prevention system.

Easy to install with the correct fittings.

You will water meter fittings for the plumbuddy then adapt to your specific pipe type. My son and I installed in less than 1 hour.

After two floods, we travel without worry

Outstanding product and impressive customer support. You are not alone in setting up PlumBuddy. The unit was highly recommended by my contractor (and installer) who was disappointed by trying to install the Moen. Plastic part broke and said to return it and get PlumBuddy. Sometimes the biggest company's products aren't the best. After two floods four years apart, we are less concerned when away for weeks at a time, knowing PlumBuddy has our backs to shut off a leak before it becomes a third lightning strike. Thanks "Buddy"!

This works great!

I have had a plumbuddy valve in my house for about a year now and have never once had any problems with it. We had a major long power outage, and it proactively shut down the water when power came back on because it sensed a leak. Sure enough, it was under a bathroom sink and we would never have known about it without this device. Highly recommended.

Great alternative to the typical options

I found PlumBuddy by doing research for lesser expensive alternatives to the usual smart shut-off valves. I had a few questions and they answered them promptly and thoroughly which was assuring. Our meter arrived slightly damaged from shipping, and though it seemed to be in good working condition and paired without problem, they still replaced it out of an abundance of caution. Check with the local utility company as this qualified for a rebate even though it wasn't listed in their pre-approved devices, which was a bonus.

Install was surprisingly straightforward

Installed the Total Protection Pack last month and it was surprisingly straightforward. The sensors and valve work exactly as expected and it's nice knowing the water will shut off automatically if something happens.

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.
