Inside, the fountain bundles water into a soft jet that sprays vertically upwards. The fountain can either be connected directly to a water pipe with an upstream pressure reducer and activation device, or to a pipe in which the water pressure is generated by a corresponding height difference. A water pressure of 0,2-0,5 bar is suitable for operation. If the supply line is in a pipe, there must be a height difference of at least 2 m to ensure proper operation.
