Works great. One note: May not work if you are attaching to a fitting with a screen filter. I attached mine to a drip system adapter and the cone shaped screen pushed in the anti siphon valve which stops flow. I had to take the screen attached to the o-ring out in the drip system fitting and flip it around (towards the flow of water). May not work for you if you can't do that.

Made sounds from it that echoed into the house plumbing. If you shut water off, stand back quickly will get your shoes wet. But overall, worked well. Took it off later mainly because of the sounds.

I bought this to replace my old pressure release spigot and it installed easier than I expected. It looks nice and it is very sturdy. One this to note is the vacuum breaker will mist water out when turning your hose sprayer nozzle off from the on position.

Perfect for house timer! Excellent fit with extra gaskets to thwart leaking! Thankful for extra gasket-accessories. Threading installation was a little hard, but I finally got it, and it’s not leaking. So far, durable this season.

Had to install these on a house I sold. Went on & work just fine.

I bought this hose bib backflow preventer thinking it would quietly do its job. Instead, it has become the most dramatic piece of plumbing hardware I own. From day one, it behaved like it was personally offended by water pressure. It leaks just enough to be annoying but not enough to be obvious, which feels intentional.Installation was technically “easy,” if your definition of easy includes questioning your life choices while crouched next to a spigot. The threads felt like they were designed by someone who has only heard about hoses in theory. It either goes on crooked or not at all—there is no middle ground.Once installed, it produces a constant, faint dripping sound that could easily be mistaken for psychological warfare. Leave it overnight and you’ll wake up wondering if your house is slowly dissolving.Performance-wise, it does prevent backflow, I assume, but at the cost of making your hose setup feel like a budget science experiment. Also, removing it? Forget it. It clamps onto your spigot like it’s trying to claim legal ownership.Overall, if your goal is to add mild frustration and ambient dripping noises to your outdoor space, this product delivers flawlessly.

It seems to be doing what it is supposed to do. It does make some funny noises in the house as the water pressure rises and falls, but that might just be my pipes.

At first, I connected one of these to the outside hose connection that goes to dual water filters to remove chlorine.What I noticed is that when we used the cold water in the kitchen sink, it would cause this to pop water out of it, which I guess is by design.The actual problem is that the outside hose pipe is connected directly to the kitchen cold water pipe.So any back pressure there causes the valve to open and close.But this isn't an issue with this one-way valve.When I put the 2nd one at the other end of the house, there was no issue.

This vacuum breaker was easy to install and fit my hose bib perfectly. The brass construction feels solid and durable, and it works exactly as intended to help prevent backflow. It's a simple upgrade that provides extra peace of mind, and the quality is excellent. Great value and highly recommended.

Perfect for RV black tank flush tank connection. Compact and prevents any backflow potential hose contamination.

works great and see it working everytime my sprinkler turns off. Didnt affect the pressure from what I could tell.
