Hkd,
Kind of depends on your plumbing..
In my case, I have one valve that feeds my waterfall wall. I remove the valve cover and use a little suction pump that you attach to a drill. I just suck the water out of the pipe until the water level that is left is below the ground level... Then I put the valve cover back on and set the valve actuator to off..
Thanks,
Jim R.
