## Description

desertcart.com: HYDRO MASTER Vacuum Breaker Valve,Hose Bib Backflow Preventer, 3/4 Inch, Brass Finish : Patio, Lawn & Garden

Review: Nice and solid. Not like the plastic ones I had that cracked. - Seems to work as intended. But time will tell.
Review: Save Yourself A Future Headache By Not Using The Snap-Off Set Screw - All of these vacuum breakers look completely identical aside from the stampings and I'm guessing they all work the same, so why pay more for one? This HYDRO MASTER appears to be solid brass and it works as intended, so it's a good value for the price I paid at the time of this review. I highly recommend installing this without the snap-off set screw (does this by design) or you will find yourself in my boat of having to replace the faucet because the breaker can't be removed when it fails, and it will eventually fail. I understand the need for these vacuum breakers to prevent potentially contaminated water from backflowing into the drinking water of one's house, but the snap-off set screw is just idiotic. If they are going to do that, then they should just make faucets with vacuum breakers as a one-piece design. Trust me, it will work just fine without the set screw, and you will thank me down the road when you don't have to spend extra money to replace a perfectly working faucet when the breaker breaks and starts spewing water everywhere. Just keep the set screw in a safe place in case you need to install it for an inspection if you are selling your house.

### ⭐⭐⭐⭐⭐ Learn what the screw is for
*by B***P on June 27, 2022*

Good quality, heavy duty backflow device. For all the "bad product, screw broke" reviewers.... The screw IS DESIGNED to break off. The screw is used to secure the device to the hose bib, then break off as to prevent the vacuum breaker from being removed from the bib, either intentionally or accidently with the garden hose when it is unscrewed.
