A pool autofill works by automatically adding water to the pool when the water level drops below a pre-set point, ensuring a consistent water level.
Here's a more detailed explanation:
-
Water Level Detection: The system relies on a sensor or a float valve to monitor the pool's water level. This is the core component that triggers the refill process.
-
Low Water Level Trigger: When the water level decreases, usually due to evaporation, splashing, or leaks, the sensor or float valve detects this drop.
-
Automatic Water Addition: Upon detecting the low water level, the autofill system opens a valve, allowing fresh water from a connected water supply line (typically a household water line) to flow into the pool.
-
Maintaining Constant Level: The system continues to add water until the sensor or float valve registers that the optimal water level has been reached. At this point, the valve closes, stopping the water flow. This process ensures the pool maintains a relatively constant water level without manual intervention.
-
Components: Common components include:
- A float valve or electronic sensor
- A housing unit or niche installed in the pool wall
- A connection to a potable water supply
- A backflow preventer (to protect the potable water supply from contamination)
The primary benefit of a pool autofill system is convenience, eliminating the need to manually add water to the pool. It also helps prevent damage to pool equipment (like pumps) that can occur when the water level gets too low.
