The gentle sound of water trickling from the old fashioned hand pump allows you to unwind in your own outside space. Using it as a background sound will make you feel calm and at peace. It works by filling the bottom barrel with water, before the pump pushes the water back up and through the old fashioned hand pump. The water falls to the top barrel filling it up and then once full in to the bottom barrel, creating a cascading effect. Made from durable weatherproof plastic the separate solar panel which is on a 3m flex can be located in a sunny spot nearby.
