Review on 🚰 Febco 1" BV - Pressure Vacuum Assembly, Model 765 by James Small

It was a lot cheaper on Amazon than my local irrigation supply store so I was worried it was fake or something was wrong. But that's the real deal. The membrane rattles when unpacked, so don't worry if you hear it. It hardens during installation and under pressure. It is very heavy so be sure to install with schedule 80 pipe/fittings. The base 40 can break from the weight. When you turn the water back on, water will spurt out from under the bell body. You may have a moment of concern that it's broken, but the flushing stops when it's fully sealed. Make sure you follow the local installation height code to protect loved ones. Amazing value for money and robust/legitimate product. Highly recommended.
