To me it sounds like freedom. Water spraying wherever it pleases. When I lived on a farm we kept the calves indoors during the winter. When it got warm enough we would let them out. It was a family event as the calves once they got outside for the first time in their lives would kick up their heels and run around.
Also, the exposure of the pipes, movement is needed for growth. Just like the plates of the earth move and shift.
