A waterfall for swimming pools has a first configuration as a waterfall and a second configuration as a water spray. Both configurations include a water accumulation box having a spiral water inlet chamber that receives water from the circulating water pump. The spiral configuration removes turbulence from the water so that the waterfall produces a smooth sheet of water. A rotary diverter valve positioned within a nonrotatable cylinder has a hand wheel at its opposite ends so that a pool user may adjust its rotary position. In a first position, a first plenum in the rotary diverter valve aligns with an interconnecting plenum that interconnects the water accumulation box and a water outlet slot to produce the waterfall, and in a second position, a plurality of smaller orifices align with the water outlet slot to produce a water spray effect.
