ABSTRACT:
A device for filling a swimming pool having a liner and a shell includes a water supply valve to control the flow of water into said swimming pool; a vacuum pump to evacuate air from the space between the liner and the shell as the swimming pool is being filled; a probe for generating a signal when the water in the pool reaches a predetermined height; and a controller responsive to the signal from the probe to shut off said water supply valve and the vacuum pump when water is detected by the probe. A current sensor monitors the current to the vacuum pump and shuts off the water supply valve when the vacuum pump ceases operation. A bypass switch allows the current sensor to be disabled.
