Abstract

Example systems and methods for manipulating control of sump pumps in order to extend lifespans of the sump pumps are disclosed. An example method includes activating a sump pump a first time; deactivating the sump pump when a first current water level in a sump basin in which the sump pump is disposed reaches a first low-water mark; and determining, by one or more processors, a time since a last activation of the sump pump wherein the last activation occurred when the sump pump activated the first time. When the time satisfies a threshold, the method activates the sump pump at second time, determines, by one or more processors, a second current water level in the sump basin, and in response to determining that the second current water level in the sump basin is below a second low-water mark corresponding to a bottom of an impeller of the sump pump, deactivates the sump pump.

Claims (43)

1. A computer-implemented method for maintaining a sump pump by reducing exposure of an impeller of the sump pump to standing water in a sump basin, the method comprising:

activating a sump pump a first time;

deactivating the sump pump when a first current water level in a sump basin in which the sump pump is disposed reaches a first low-water mark;

determining, by one or more processors, a time since a last activation of the sump pump, wherein the last activation occurred when the sump pump activated the first time; and

when the time satisfies a threshold,

activating, by one or more processors, the sump pump a second time and reducing a water level in the sump basin to a level below a bottom of an impeller,

determining, by one or more processors, a second current water level in the sump basin, including sensing the water level with a sensor positioned at the sump basin, and

in response to determining that the second current water level in the sump basin is below a second low-water mark corresponding to the bottom of the impeller, deactivating, by one or more processors, the sump pump, wherein the second low-water mark is below the first low-water mark.

2. The computer-implemented method of claim 1 , further comprising proving an alert when the second current water level in the sump basin is not falling in response to activating the sump pump the second time.

3. The computer-implemented method of claim 1 , wherein determining the second current water level includes sensing the second current water level with a sensor positioned below the first low-water mark.

4. The computer-implemented method of claim 3 , wherein the sensor comprises a water level sensor.

5. The computer-implemented method of claim 3 , wherein the sensor comprises at least one of a force sensor or accelerometer.

6. The computer-implemented method of claim 1 , wherein determining that the second current water level in the sump basin is below the second low-water mark includes detecting whether water in the sump basin is moving.

7. The computer-implemented method of claim 1 , wherein the threshold corresponds to fourteen days.

8. A non-transitory, computer-readable storage medium storing computer-readable instructions that, when executed by one or more processors of a sump pump system, cause the sump pump system to:

activate a sump pump a first time;

deactivate the sump pump when a first current water level in a sump basin in which the sump pump is disposed reaches a first low-water mark;

determine a time since a last activation of the sump pump, wherein the last activation occurred when the sump pump activated the first time; and

when the time satisfies a threshold,

activate the sump pump a second time and reduce a water level in the sump basin to a level below a bottom of an impeller,

detect, with a sensor, a second current water level in the sump basin, including sensing the water level with a sensor positioned at the sump basin, and

in response to detecting that the second current water level in the sump basin is below a second low-water mark corresponding to the bottom of the impeller, deactivate the sump pump, wherein the second low-water mark is below the first low-water mark.

9. The non-transitory, computer-readable storage medium of claim 8 , wherein the sensor is positioned below the first low-water mark.

10. The non-transitory, computer-readable storage medium of claim 8 , wherein the computer-readable instructions, when executed by one or more processors of the sump pump system, cause the sump pump system to determine that the second current water level in the sump basin is below the second low-water mark by detecting whether water in the sump basin is moving.

11. The non-transitory, computer-readable storage medium of claim 8 , wherein the threshold corresponds to fourteen days.

12. The non-transitory, computer-readable storage medium of claim 8 , wherein the sensor comprises a force sensor.

13. The non-transitory, computer-readable storage medium of claim 8 , wherein the sensor comprises an accelerometer.

14. A computer-implemented method for maintaining a sump pump, the method comprising:

determining, by one or more processors, a water event; and

when the water event is ended

activating, by one or more processors, the sump pump to reduce exposure of an impeller of the sump pump to standing water in the sump basin,

detecting, with a sensor positioned at the sump basin, a current water level in a sump basin in which the sump pump is disposed, wherein the sensor is configured to detect at least one of acceleration or force, and

in response to determining that the current water level in the sump basin is below a level corresponding to a bottom of the impeller, deactivating, by one or more processors, the sump pump, wherein the level corresponding to the bottom of the impeller is a second low-water mark below a first low-water mark at which the sump pump is configured to be initially deactivated.

15. A computer-implemented method of claim 14 , wherein determining the water event includes determining a number of sump pump activations in a period of time exceeding a threshold.

16. A computer-implemented method of claim 14 , wherein determining the water event includes:

determining, during a first time period, a first number of sump pump activations in a first period of time exceeding a first threshold; and

determining, during a second time period, a second number of sump pump activations in a second subsequent period of time below a second, lower threshold.

17. A computer-implemented method of claim 14 , wherein determining the water event includes:

during a first time period, determining that a rate at which water is rising in the sump basin exceeds a first threshold; and

during a second, later time period, determining that a rate at which water is rising in the sump basin is less than a second, lower threshold.

18. The computer-implemented method of claim 14 , wherein determining the water event further includes determining that water has stopped rising in the sump basin.

19. The computer-implemented method of claim 14 , wherein the sensor is positioned below the level corresponding to the bottom of the impeller.

20. The computer-implemented method of claim 14 , wherein the sensor comprises an accelerometer, a piezoelectric crystal, or a pneumatic, a hydraulic, an inductive, a capacitive, a magnetostrictive, or a strain gage load cell.
