If the pipe is tight, no air intake, just prime once and then close at the bottom. Always downstairs, on arrival. And the pipe remains full ... Provided that at the top, no water comes out, or that the basin is never dry: otherwise, a large buried container, with the pipe at the bottom, can do "water reserve" and ensure airtightness if the basin empties sometimes ... Of course, only open at the bottom when there is enough water at the top ...

Plan B: put a T with a tap at the highest point (possibly, put the pipe so as to avoid huats and downs, cross the coast and then follow almost in a contour - this is not necessarily the way the shortest, but the one that will avoid air pockets) and two faucets at each end. Close the bottom faucets and fill at the high point so the T with a bucket and a funnel. When there are no more bubbles, close the tap of the T. And open up. Then serve at the bottom. This system allows to purge in autumn and put off frost. A spring filling and basta. Always if everything is waterproof.

Hello everyone.
A personal experience led me to note that the pipe can and must have a diameter as small as possible so that the volume of water to be sucked for the priming of the syphon represents the least possible volume of water.
The flow is amazing. I, to ensure the feeding of a trough for four horses (draft, maous / beefy) set up a pipe 10 mm in diameter. I got a flow on 24 hours of about 4000 liters. I was surprised, but that's what I was able to measure ...

it depends on the height difference and the length ...
Me for my horses I have 250m of pipe in diam 20, but with only 2m of difference in level, the flow is then likewise not 3000l / 24h

problem solved ?

in fact the strainer and the pipe remain permanently in place (in the brook and up to our place).

Currently, when pumping "down" the water arrives well after some pumping efforts and a little patience. The system is working well. but if another means exists, one is a taker.

On the other hand, we do not have any hose and especially water available to fill the pipe at the bottom ... The solution is not conceivable ...

The idea is to know if the manual pumping system for priming is the best alternative, if yes should you choose a hand pump or a "round" pump with a crank that turns 360 °? I do not know this kind of pump and I saw that both types exist in stores ...

Thanks in advance for your advice.

Hello, have you solved the problem of siphoning to bring water from the creek home, we would like to know what is the siphon http://www.youtube.com/watch?v=8lXl7tdJ7iY
