Abstract: A pump system or device is provided for removing water from a pool cover or sump, featuring a controller configured to respond to a signal containing information about the ambient temperature in relation to a pump and to provide a controller signal containing information to control the operation of the pump based at least partly on the ambient temperature. The pumping system or device me be configured to include some combination of the following: temperature sensing, including a Thermistor, to change control logic at temperatures below a specific level (e.g. below 35 degrees F.); the initiation of impeller cycling at low operating temperatures to avoid ice formation in the impeller cavity and/or hose, but not for level sensing; the use of temperature feedback to turn off pump at low temperatures that may result in damage to the system; the addition of control logic to ignore torque increases due to contamination or flow-back Inclusion of soft-start of motor to reduce stress on impeller/motor; the option to connect Garden-style hose with an integral heating element to avoid freezing; a heating element to receive power from the pump via, e.g., a plug connector, where power to the heating element is supplied only when the temperature device is activated at some specified setting; the addition of a temperature sensor to render the pump inoperative if the temperature should fall below a set point (freezing); and/or the use of a field effect level sensor, such that the temperature sensing is substantially independent of the level sensing device.

Abstract: A check valve is provided having a seat and a poppet. The seat is made of a plastic material, has an aperture for enabling fluid to flow through the seat, and also has one end portion that has a circumferential edge with a thin sealing lip. The poppet is slidably arranged in the aperture of the seat and has an elastic member. The poppet is configured for opening to enable fluid to flow in one direction when fluid pressure is detected. The elastic member is configured for ensuring sealing between an outer surface of the poppet and the thin sealing lip of the seat when there is no fluid flow in the one direction so as to substantially prevent fluid flow in the opposite direction. According to some embodiments of the present invention, the thin plastic sealing lip may have a thickness of about 0.01″ Embodiments are also envisioned where the thickness may be in a range of 0.003″-0.03″.
