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!

Not for use in potable water systems.
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.
