Pond Boss Forums POND CONSTRUCTION Renovating a Pond or Lake? Pond Rebuild Qs-> Liner v No Liner

I have emptied or lowered several ponds very economically with 2 to 4" pvc pipe, glue together several lengths down the inside of the dam, (whatever it takes to reach close to the bottom of the pond), then a 45% elbow across the top of the dam and another 45% elbow then down the backside of the dam to a point lower then the intake end. glue a check valve on the inside end and a regular valve on the outside end and a tee with a short pipe and a threaded cap straight up in the line in the highest point on top of the dam, you can fill the whole pipe up with water from a garden hose or small pump or even a bucket thru the tee on top of the dam, then close the tee off and go to the back side of the dam and open the valve and it will start the siphon.
I will try to attach a sketch of what I am trying to describe.
