Okay I need your help determining if this will work or not. I'd rather not invest the time or money if there is no possibility of success. Currently I have a 5 acre pond with a 12" syphon system. I have installed a butterfly valve on the outlet of the 12" pipe as a means to hold the pond at a higher level. Please don't freak out. I have a more than adequate concrete overflow spillway. I currently hold the water level a few inches below overflow and can open the valve should a substantial rain event occur. My question is, can I tap into the 12" pipe before the butterfly valve, install a hose bibb, and water the grass growing on the backside of the dam? The 12" pipe stays completely full and if I open the valve it will syphon as it should. Those of you familiar with a syphon system are aware of the volume of water that leaves the pipe when in syphon mode.

Please share your thoughts, suggestions, and ideas.

Thanks, Dean
