Pinching is much quicker if I want to modulate the flow, but yeah, the valve works too.Indeed, it does....with the Python, there's a shutoff valve at the siphon end, no need to pinch the hose to restrict flow...once the flow is established, you can regulate the flow rate, or even turn it off completely, with the valve...my gravity drop for all of my tanks is 6', or so
