The Fiber Optic Rain Waterfall is a unique 12” fiber waterfall that adds nighttime excitement to any pool. The Rain Waterfall comes complete with fiber pre-attached and is designed to provide single rows of water that are projected away from the fall’s lip at a 45 degree angle. The minimum water flow is between 5 and 8 GPM. Increasing the GPM flow rate causes the “rain” to fall further out from the wall on the pool.
