Great Product!
This is very well built and saved me alot of money hiring a Sprinkler Tech! Worked perfectly and I was able to add some CPVC Elbows and bring it out and away from the house creating a better installation than previously done. Great product for the price!

Great Product and experience buying
This was exactly what I needed! I appreciate the swift purchase and easy install. It was for a Good Price and fast delivery. It fits well and won't leak if you put Teflon tape or sealant on the fitting. Make sure you Google the right installation instructions.

Cost-effective Solution for DIY Sprinkler System
I love how well-made this product is! It saved me a significant amount of money by allowing me to handle the installation myself. The results were perfect, and I could easily enhance the setup with CPVC elbows, improving the overall installation compared to before. Highly recommend for its affordability and quality!

Works great but not lead free
This works great however it is not lead free as required by local code. Hopefully they won’t figure it out

... or ace or (insert store here) and it's very easy to install
I bought this because it was way more affordable than going to home depot or lowes or ace or (insert store here) and it's very easy to install. I had zero experience with sprinkler watering systems until now, but now I am a self proclaimed expert. so with this product... After years of struggling to keep my grass watered and striving to have my yard look better than the neighbors I decided to carve in 400+' of sprinkler line and 4 zones. I made everything up to my connection on both side where this backflow valve connects, it was so simple to install my 9 year old did most of it because she needs to do something on her time on summer vacation right?. Our water district require annual inspections and an inspection upon installation. It passed inspection full of complements and praise (no joke, I guess there are a lot of really "really terrible installations out there). The inspector said this brand was top notch . I didn't know when purchasing it, I just wanted to save $35-$40 at the time, that's a nice bonus to hear though right? The only negative is that I have too much extra time on my hands because I don't have to worry about watering a lawn with a flawless automatic watering system. What do I do now? You guys should send me on an annual vacation as compensation for having to deal with all this extra time

Good quality product so far for our pool's auto filler
Had one of these on our property that works with our pool auto filler, and it started leaking, but it was like 9 years old and had been out in the Arizona heat doing a good job all those years. Jumped on Amazon, ordered a new one, had a local plumber put it in, and it works fantastic! Plumber installed it in about a half an hour. I included before and after photos of our old one and new one. I recommend this product, but do recommend covering it in extremely cold weather.

Product was well built and solid. Did what it was supposed to. Unfortunately, I found out that even though I was installing the vacuum breaker on my irrigation system, my municipality requires that the device meet low lead requirements for potable water systems since I was tapping into their drinking water system. Ended up replacing with a substantially more expensive "Low-Lead Law Compliant" Wilkins/Zurn 1-760XL. Fortunately I had ordered the 1-720A on Amazon and was able to return in hassle free for a full refund.

I have installed it. I first put it the wrong way and it did block all the water from coming back. Very good.
