the innertube is still inside but I drilled a hole through the plastic pipe tank and installed the innertube valve stem through it so it sticks out the side of the tank and can be used to fill the tube from the outside of the tank without taking apart the tank so the pump does not have to be stopped and drained to fill up the innertube.

Derek says labour costs varies, depending on the type of site and distance travelled to the site but he says, on average, he would have to charge 600 excluding VAT for the two days work to install the system. Fencing the river caused problems for Tom because there was no pumped water system on the farm and, prior to Glas, he had water points where the heifers could go to drink in the river. The water continues down the 2in pipe and into a check valve. e.g. (like an aqueduct system) The less water your pump must push up a pipe to the end use location the more volume it will deliver. The pressure was measured at the pump outlet with a standard water pressure guage. There is also another green water powered pump claiming to be the "Most Powerful Water Powered Pump in the World" on YouTube, https://www.youtube.com/watch?v=iKDym5sWpsc.

The 4in pipe acts as a reservoir of water, which makes sure there is a constant supply of water to the system further down.
Derek used 4in diameter plastic pipe and the opening was set in a rock pool in the river. so lock it down strongly, I used 4 x 3' fence bars bolted to a board and a 10" concrete block.
