We wire the auto leveler sensor into a skimmer body. When the water falls below the level of the probes the auto-leveler valve opens up.
Down in the equipment room this valve opens to fill the pool when too much water has evaporated or been splashed out by bathers.
All our pools come with full chemical automation. This does not eliminate the need for a CPO (certified pool operator) any more than cruse control eleiminates the need for a driver, but it sure make pool ownership a LOT easier.
Because this equipment room is in a parking garage the pump and heater needed to be elevated 18" off the floor.
