You do not need to suck on the hose:o but you could if you want to.:redface:
Connect the hose to a water tap. Ensure other end of hose is in the pool. Turn on tap. When water is flowing into pool pull hose off tap. The water will start to flow in the reverse direction and empty pool. Another way is to put most of the hose in the pool and ensure that the hose fills with water. Take one end of the hose and while it is still under the water kink it to prevent air entering then take it outside. Lay it on the floor, let it go and the water will flow from the pool.
For the above methods to work the garden needs to be lower than the floor of the pool.
