Pond Boss Forums POND CONSTRUCTION Building a dam Stand Pipe and Overflow Pipe?

Ric,

Thanks for clearing up bigfrogs question for me. Raising and lowering - yes, that IS a big advantage.

I assumed most stand pipes did not have drain value (mine didnt) and couldnt figure out why go to all of that trouble to build a stand pipe when a simple overflow pipe would do the same thing.

I get it now thanks.

The puzzleing thing is why build a stand pipe without a drain valve...go figure.

BigFrog,

I would like to revise my comments.

Stand Pipe with drain valve = good.

or

Syphon System = good.

Spillway good.

Not sure why you would need a overflow pipe in addition to one of the above. I suppose a good overflow pipe woudnt hurt, but a spillway does the same.

I cant speak to the maintenance issues with the valves - I think Ric and others addressed that. I can say that my stand pipe rotted and drained my lake. Like Ric, I filled in the "hole in the bottom of my dam" and went back with a Syphon design.

I am biased against holes in the dam since I had trouble with mine, others have not had any issues.
