Pond Boss Forums INTRO Questions & Observations The finer points of a vaccum breaker vs. a siphon

Well, I finally got to see my vaccum breaker drainage system in action today. A couple of thoughts here:

First - I like the vaccum breaker design. It occured to me that it is practically fool proof in releasing the vaccum. This will prevent accidental draw downs due to a clogged siphon release pipe. Since I am a absentee owner, this seems like a good design for me.

Second - the siphon releases sooner than on a traditional inverted U design and therefore the lake drains at a slower rate after the water level drops below the actual vaccum breaker pipe. The last 2 feet of water to drian due to gravity, not siphon. I'm not sure if this is good or bad...could be good if I go long periods between rain events. That way the lake will hold a higher level, longer. Not sure what the down side is (yet).

Overall, it looks good on the first run. I would like to see it running at full force.
