Automatic liquid collection and disposal assembly

A liquid collection and disposal assembly for collecting and disposing drainage liquid, comprising:

• a basin having a collection cavity in liquid communication with the pit, the basin having a cover over the collection cavity,
• a pump and motor assembly comprising:
• a pump having an outer housing and an inner housing forming a liquid flow path between the outer and inner housings;
• a motor powering the pump and disposed in the inner housing and sealed from the liquid flow path;
• and
• means removably connecting the pump to the cover, the pump and motor assembly supported by the cover for removable placement in the basin a predetermined distance above the bottom of the basin;
• level detector means for detecting when the liquid level reaches predetermined levels in the collection cavity, the level detector means having a lower limit probe, an intermediate limit probe and an upper limit probe for detecting liquid levels;
• and
• control means responsive to the level detector means for activating the motor means to power the pump, the control means issuing an activate motor signal when liquid is detected by the intermediate limit probe, the control means issuing an alarm signal when liquid is detected by the high level probe, and the control means has an alert light and an audible alarm that are activated by the alarm signal.

A liquid collection and disposal assembly for collecting drainage liquid in a pit, comprising:

• a basin disposable in the pit and having a collection cavity in liquid communication with the pit, the basin having a transparent cover over the collection cavity;
• a pump and motor assembly;
• a pump having a discharge port;
• a motor powering the pump and sealed from the liquid;
• and
• means removably connecting the pump to the cover, the pump and motor supported by the cover in the basin a predetermined distance above the bottom of the basin, said means comprising:
• a mounting coupling connected to the cover and extending therethrough;
• and
• a discharge pipe having one end connected to the mounting coupling and mounting another end connected to the discharge port of the pump, the coupling and discharge pipe supporting the pump and motor assembly from the cover for removeable placement in the collection cavity of the basin;
• means for detecting when the liquid level reaches predetermined levels in the collection cavity, the level detector means having a lower limit probe, an intermediate limit probe and an upper limit probe for detecting liquid levels;
• and
• control means responsive to the level detector means for activating the motor means to power the pump, the control means issuing an activate motor signal when liquid is detected by the intermediate limit probe and issuing an alarm signal when liquid is detected by the high level probe, the control means having an alert light and an audible alarm activated by the alarm signal.
