Abstract
A system for detecting liquid in an inground lift has a tube with an open end disposed within the internal cavity defined by the containment housing of the inground lift. The tube is in fluid communication with a source of pressurized gas. A pressure sensor generates a signal if the pressure within the air line exceeds a predetermined level, which occurs if the end is blocked by liquid. A control system is configured to respond to the signal.
