Litorange 2 Pack Brass 3/4" Inch GHT Hose Bibb Connector Backflow Preventer Vacuum Breaker

Summary: These brass vacuum breakers fit standard garden hoses perfectly, install quickly, and create a secure, leak‑free connection. Strong material and reliable performance make them a great replacement for older stuck or failing units. Details: I bought this 2‑pack after dealing with a stubborn old vacuum breaker that had fused itself to my hose. Removing it required so much force that the entire thing ended up unusable. Because I didn’t want to repeat that experience, I selected these based on strong reviews — and they absolutely lived up to the feedback. The build quality is excellent. The units are made of heavy, durable brass that feels much more substantial than cheaper alternatives. They thread smoothly onto standard 3/4‑inch hose bibs, spigots, and outdoor faucets, and the fit is snug without needing excessive tightening. With the included thread tape, I didn’t notice a single drop of leakage, even when the spigot wasn’t fully closed. Many high‑rated reviews mention the same leak‑free performance. One of the key features is the anti‑backflow function, which prevents contaminated hose water from siphoning back into your home’s water supply — something every outdoor faucet should have. These also meet ASSE 1011 and ANSI/NSF safety standards, which adds confidence in long‑term reliability. The break‑off screw allows permanent installation if needed, and the built‑in drain hole is helpful for releasing leftover water. Just be aware that when turning the water off, the pressure release can spray a bit — something recent medium‑rated reviews also mention. It isn’t a flaw, just how vacuum breakers work, but worth keeping in mind. Overall, installation is simple, the fit is perfect, and the material feels durable enough to last many seasons. After struggling with a stuck breaker before, this was a huge improvement. What I liked • Heavy‑duty solid brass construction • Fits standard garden hoses and outdoor faucets perfectly • Leak‑free connection with included tape and washers • Prevents backflow and protects water supply • Smooth threads, easy installation • Meets quality and safety standards • Comes in a useful 2‑pack What could be better • A small directional guide for the drain hole would help avoid getting sprayed • Color‑coded or marked indicators for easy orientation

1. I absolutely love the Litorange 2 Pack Brass 3/4" Inch GHT Hose Bibb Connector Backflow Preventer Vacuum Breaker. The brass construction feels sturdy and durable, and I appreciate the added peace of mind knowing that it helps prevent backflow in my garden hose. It was easy to install and has worked flawlessly since I started using it. 2. One thing I dislike about this product is that it only comes in a 2 pack. While having a spare is nice, I only needed one for my garden hose setup. It would be great if they offered a single option for those who don't need multiple connectors. 3. The Litorange hose bibb connector has been a game changer for my outdoor watering needs. The vacuum breaker feature is a must-have for anyone who wants to ensure their water remains clean and safe to use. I haven't had any issues with leaks or malfunctions, and I appreciate the quality craftsmanship of the brass material. 4. My only dislike about this product is that the price point is a bit higher compared to other hose bibb connectors on the market. However, I believe the added benefits and peace of mind it provides are well worth the investment. 5. Overall, I highly recommend the Litorange 2 Pack Brass 3/4" Inch GHT Hose Bibb Connector Backflow Preventer Vacuum Breaker. It's a high-quality product that delivers on its promises and has made my gardening experience more convenient and worry-free. The only downside is the price, but I believe the benefits outweigh the cost.

SHIPPING WAS VERY PROMPT....PACKAGED GOODS WERE IN GOOD SHAPE. NOT SURE IF THE VALVE REALLY WORKS AS A BACK-FLOW RELEASE..OR MERELY A BREAK TO KEEP HOSE WATER OUT. VERY NOISY WHEN THE GATE VALVE IS OPENED FULLY.

I’ve been using garden hose back flow regulators for 30 years. I’m familiar with their function and operation. We had an old leaky one, so I ordered this new two-pack. After trying both repeatedly, they simply didn’t work. The expected water evacuation (spray from the valve) did not occur. Also, the devices produced a lot of noise when the hose was running. The reviews are generally good, so I guess we just had some rare issue with both valves. Rather than exchanging them, we went on to a different brand. I’m sure the seller would have made good, but we decided to skip the hassle. EDIT: We purchased another brand and it works properly. That seems to rule out any role of the hose type or our hose bib etc.

These work great. Note that the subassemblies are also screwed together. Be careful not to disassemble while only trying to disconnect the hose.

Excellent design, materials used, and ease of installation. Installed and tested two several times. The Litorange 2 Pack Brass 3/4" Inch GHT Hose Bibb Connector Backflow Preventer Vacuum Breakers worked perfectly each time straight out of the box. I should have purchased these sooner!

Good backflow connector. Quality looks good and no leaks while installed on outdoor faucets.

I hope these do what they're supposed to do, hard to tell. But the 2 I bought both leak under pressure. I've used the supplied washers and tightened them repeatedly but continue to get a spray out of the valve when turning on the faucet. It seems to stop after a minute or two but then returns.I'm going to remove both and try new washers but I'm disappointed at this point. I accidentally left one valve on in my garage and it leaked a substantial amount of water overnight. Considering going to a full soldered antisiphon system as I should have initially.

They work! No complaints.

Perfect for my outdoor water hose

These are very well constructed compared to the plastic one I have. They should last longer. They connect fine and work as they should. The only issues I had with both is at both outside taps when the water was running they would make on and off high pitch humming / squealing sounds. Definitely wakes you up if your system is on the timer. I tried purging any air in system, tried turning taps on and off, even tired the tap only half on to help reduce pressure but it didn’t stop it. I ended up removing them from my tap directly and moved them further down the hose to another connection. I don’t hear the sounds anymore even when running when I’m standing right next to it so it must just be the water pressure at the tap causing the problem. All in all very well built but the sound made it not possible for me to use as I intended. But I am using it just not directly at the house tap.

Perfect for my garage bibs and lile doesn't hit hard anymore and quieter

Highly recommended
