DIY Pond Drain-Siphon

My pond has a Drain that is no longer in service due to rust and having holes in it, it started last year, noticed my pond was always disharging water out of the drain pipe and had to plug off the outlet for it to stop the leak, SO i now have to manually start-siphon excess water from the pond, i did not have the money for trash pump, but i did have enough for some pip and fittings, this will run for about 4 days, dropping about a inch per day, on my pond, depending on how saturated the surrounding land is, and or when it last rained, total cost was under $100 and it shuts off when it hits the desired level. it takes about 4 minutes to fill and start the siphon, sometimes you work with whats available to you, in this case, this was my option, seeing i have to drain it every time it rains hard, i could use the water to power a small generator to a battery bank for some lights for night time use on the dam maybe? Enjoy !
