Shove the whole pipe into the pond letting it fill with water. Plug the downhill side. Pull the plugged end with a tractor to the drainage area. Open the plug. Watch it for 10 minutes, then you'll have to go to the bathroom yourself.

Put a valve on the discharge end, close. At the high point install a clean out. Use a small gas powered pump to fill the discharge pipe. Cap and seal the clean out. Make sue your intake pipe is in the water, walk down hill and open valve. Presto. The discharging water creates a vacuum in the pipe that will pull water up out of the pond and over the hill and you have a fully operational and functioning siphon.

The filter

All set to go, except for one bit of detail. How do you prime a siphon that's over 200 yards in length ?

Somehow I think he already has an answer .... to be divulged in the next installment.

Just caught on to this thread. Mossroad has it IMO. Maybe not considering the length and mass and amount of manpower available.

I will stay tuned in for sure.

On a side note, I googled Shropshire on the map and noticed it was close to Birmingham(just east of Shropshire). When I was young, I used to listen to a heavy metal band from Birmingham. I just missed them playing a concert last Thursday near Austin.

Prime Time
I really wish I had found TBN back in 2006. We could have gone through all those priming suggestions together (well, at least the sensible ones. Dave1949's tractor was too far away to borrow and try some of the others) and figured out the best solution. Most of the people I talked to at the time thought I was nuts to try sucking a pond dry with a siphon. They would almost fall asleep when I talked of the various options. I was becoming a sad siphon geek.

Two possible solutions stood out at the time. Being a simple person, I tend to like simple solutions.


Gravity Prime
One option was to fit a valve on the pipe coming out of the filter, making sure the valve could be operated while under water in the sump, plus a second valve at the discharge end. Close both valves. Cut the pipe at the highest point and put in a T with a valve on. Fit a bowl on above the T and keep pouring water in until the pipe is full. Close the valve on the T, open the valve in the sump first, then the valve on the outlet. Only drawback would be carting water to the high point.
It also needed 3 valves and I was a cheapskate.

Pump Prime
Sounds easy, just use a pump to fill the pipe, then disconnect the pump.

Fill the pipe with water by pumping water into the outlet end.
If you want to try this at home, this is the way to go. Simplest of all. Why didn't it occur to me to try that ? Possibly because at times I am quite stupid and possibly because there was no water at that end. At the time I didn't have anything portable that would hold more than 50 gallons and filling a 2" pipe takes a lot of water.


I decided to have a go at pumping from the pond side. It would need a fair size pump to keep the pipe full until the syphon got going. If not, the pipe going down the hill to the outlet would have air in. My pump wasn't big enough, but fortunately I was able to borrow a bigger one. Once the siphon was running I would need to take the pump away, so some kind of joint was needed. A T was the obvious choice.
pump with valves.jpg Shut valve to filter, open valve to pump. When water comes out of the outlet, open valve to filter then close off pump valve.

If this was to be used often valves would be a good way to go, but as a cheapskate trying to do this for free, I opted to make a push fit on the end of the pipe.

All ready to start pumping.
