Product arrived fast and save me hundreds of dollars from local purchase. Install was easy and product worked as needed. As I am not a plumber I was happy that it was so simple to change this out myself.

This is used as a vacuum breaker for outdoor irrigation system. It is not intended for use where water spillage is an issue--it will "burp" quite a bit of water in normal operation with every pressure change. For household or code-compliant use, you need a dual pressure zone type backflow preventer.
