1" plastic ram pump with brass impetus valve. ( Brass spring check valve ) The non return valve is a very simple type, using just a plastic ball, no springs to worry about very simple and effective. I've made a change to the pressure vessel and used a plastic mineral water bottle instead of the 25 mm pipe. It gives a more constant flow and is more compact. Please check my other films as i have got some demos showing the pump pumping water to a much greater height. Thanks for watching.
