The Fill Rite vacuum breaker is a must-have for anyone in the industrial and scientific world of cleaning. My analysis of this product showed that it effectively prevents back siphoning and backflow, which ensures a clean and safe work environment. Its DURABILITY is top-notch, which means its longevity will save you some money. However, the installation process is a bit complicated and requires some technical know-how, but once you get it done, you`ll be able to focus on your cleaning tasks without any worries. Highly recommend!
