This pre-filter helps keep the overflow tank clean by trapping leaves and debris flowing in from the pool. Its large capacity allows it to collect a considerable amount of leaves and makes them easy to remove.
By preventing leaves from reaching the tank, it helps to prevent blockages in the return valve and the accidental draining of the pool. Cleaning is simple: simply open the stopcock located at the bottom, which is connected to the drain, to empty the contents in approximately 10 seconds.
