This valve fills 50% faster than other valves. There are no levers to flip or valve to close.\u003c\/p\u003e\n\n\u003cp\u003ePre-assembled with the 573 series backflow preventer, the AutoFill? Combo features an atmospheric vent which is designed to protect drinking water systems from return fl ow, caused by back-siphoning or back pressure, of contaminated fluids. The 573 series has been specifically certified to standards CSA B64.3 and ASSE 1012.\u003c\/p\u003e\n\n\u003ch3\u003eProduct Features\u003c\/h3\u003e\n\n\u003cul\u003e\n\u003cli\u003eAutomatic Fast-filling: Fast fills the system to set pressure then automatically shuts off the water feed.
