Every fish tank owner with apparatus requiring flexible pvc hosing or pvc pipe to connect water lines should have safety devices including "Check Valves". Check Valves will stop centrifugal force which creates a reverse back flow of water which flows in reverse, thus creating flooding in the event of a power failure or when shutting the pump off for maintenance and/or feeding times.
