Aqua One AquaFill Automatic Top Up Unit
The AquaFill automatic top up system is designed to maintain a stable water level in a sump.
In marine systems, automatic top up aids in maintaining stable and consistent salinity levels by providing small amounts of replacement water constantly as evaporation occurs. The 3 float switch system ensures reliability and prevents damage to the top up pump in the event the reservoir is emptied.
