POOL CLEANING SYSTEM

PURPOSE:To supply the water for back flushing to a filtering machine by a filtering pump from a balancing tank having a small capacity by reducing the electricity charge necessary for the supply of water to a pool, shortening the water pouring time and permitting filtration cleaning for the dirt on the bottom of a pool. CONSTITUTION:The water in a balancing tank 10 is poured into a pool 2 through a communication pipe 36 by opening a control valve 38. A control valve 40 is controlled to a prescribed opening degree, and the water in an overflow groove 12 is returned into the balancing tank 10, and the water in the pool 2 is introduced into the balancing tank 10 through the communication pipe 36, and the water is filtered by a filtering machine 24 by driving a filtering pump 20. The water in the pool 2 is introduced as back flush water into the balancing tank 10 from the communication pipe 36 by opening control valves 42 and 44.
