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.

The one to use
I had to put one in because of my sprinkler system. It's a little spendy, but worth it,good quality and easy to install. Make sure you know how to install it properly,( you tube video )

Best price available to consumers in Canada.
Solid, heavy, the real deal.It's more economical to buy 1" and then 1" to 3/4" PVC adapters than to buy the 3/4" version of the vacuum breaker.I decided against paying 50% more for a frost-safe model because in either case they both should connected with unions to the sprinkler system, and disconnected and stored indoors during winter.
