Pond Boss Forums AERATION Systems questions Overflow pipe leak, could lose the pond

Lunker,

You were so right on putting the pipe back. I was buried again this morning. The overflow has probably 5 inches to move so we are pretty much at max flow and the end was buried again. I just realized part of the problem was that the pipe above this last section comes downhill at probably 15-25 degrees and the last pipe is mostly flat. No sort of bent section connecting them together, no anti-seep collar either. I have them close together, not joined or coupled yet.

Last new observation, I've probably a 6 inch overflow pipe, not 12. Looked larger than I thought but probably 6 inches. Another flow observation the two 90 degree turns on the surface of the water (inverted p-trap) allows water in and keeps from getting clogged but may restrict flow more than I need. Will monitor this to see if it was designed well to handle the flow.
