Excellent Quality โ Zero Leaks!
I bought this Eastman 3/4" Hose Bibb Anti-Siphon Vacuum Breaker to replace an old, spraying valve, and it has exceeded my expectations. Right out of the packaging, you can tell the build quality is solid and durable. Installation was incredibly easy and took less than a minute. The threads are cleanly cut, allowing it to screw onto the outdoor faucet perfectly without any cross-threading. The best part? Absolutely zero leaks. When the water is turned wide open, the seal holds perfectly tight with no annoying drips or spraying from the sides. It does exactly what it's supposed to do, holding up to full water pressure effortlessly while providing great peace of mind for backflow prevention. If you need a reliable, high-quality vacuum breaker that actually seals right the first time, this is the one to get. Highly recommended!

As expected.
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.

Great product - note: may not work if you are attaching to fitting with screen filter
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.

Good quality back-flow preventer!
A good product which provides effective back-flow prevention. Well priced!

Works, no drips
It makes a weird whine when my automatic pet water bowl is filling up, but that's probably because the flow is low. No noise when the hose is running through the Y I attached after it.
