I am trying to drain my 1.25 acre pond to do some work on the levee. I am using 4" corrugated drain tile because that is what I had on hand.
I attempted the "fill the tile and drop down the backside of the levee method" but could never get a flow going. So I rigged a cap for the drain side and put a tee in up top to fill the tile and then capped it off once the tile was full.
Once the siphon was started it would run for about 5 minutes then tapper off and quit. This would happen every time I would start it. There was no blockage at the intake to stop the siphon so I cannot figure out what is causing it to stop.
Is it possible� the fact it runs the same amount of time every time, that it is taking on air somewhere and killing the siphon?
Thanks!
Tom
