Hi folks,
I am also in the club of pond owners with a failing corrugated metal drain serving as primary spillway. I am quite interested in replacing the failing system with a pond siphon, and I think the pond would be well suited to it in terms of placing the through the dam pipe at the desire water level vs. the elevation of the emergency spillway. However, I am wondering about peoples experience or satisfaction with siphon systems in regard to maintaining a relatively constant water level. The existing system has a 24" vertical riser which drops 4' and then drains out through a 15" inch tube, so the water level remains pretty constant unless you get a pretty good rain and even then it takes it back to normal pool pretty quick. With a siphon, which I anticipate would be 12" pipe aren't I going to have quite a bit of rise before it begins moving very much water? So I am going to be subject to rises of several more inches than we typically experience with the standpipe system, right? I probably wouldn't care much about 4-6 inches regularly, but 9-12 inches all the time might be less than desireable in my view. Anyone have any thoughts?
Also, I really don't want to go the route of multiple smaller siphon tubes due to the inceasing expense.
Thanks,
Matt
