Methods and devices for detecting the level of water (12) in a swimming pool (10) and controlling that level. A water level sensor (50), preferably disposed beneath the skimmer cap (52) for a pool (10), has a magnetic or electronic float assembly (56, 58) and a transmitter (64) for providing a signal, such as a radio frequency or infrared signal (74). A flow controller having a receiver unit (72) and a valve assembly (78) is associated with a water inflow line (20) that replenishes the pool water (12). A low water condition in the pool (10), triggers the float switch (56) to cause the transmitter (64) to generate a signal (74) indicative of a low water condition. The receiver unit (72) receives the signal (74) generated by the transmitter (64) and, in response thereto, selectively actuates the valve assembly (78).
