A position detector for a check valve, including a bracket with a support arm, adjustable securing members adapted to rigidly secure the bracket to a check valve arm, a tilt switch, a connector, a circuit status indicator, a wire connector for both the tilt switch and the circuit status indicator, and a first plug. The connector adjustably connects the tilt switch to the bracket support arm in a selected one of a plurality of secure positions pivoted around an axis fixed to the bracket support arm, the axis being oriented generally horizontally when the securing members secure the bracket to the check valve arm. The first plug is selectively securable to the wire connector whereby a first circuit with the tilt switch and the circuit status indicator is formed when the tilt switch is in a selected position.

The invention claimed is: 1. A position detector for a check valve having a check valve arm pivotable responsive to a change in position of the check valve, comprising: a bracket having a long leg generally parallel to a small leg, said long and small legs interconnected at their lower ends by a bottom leg, and a support arm extending from the upper end of the long leg, said support arm being spaced from said small leg and including a portion facing said bottom leg, wherein said check valve arm is receivable between said support arm and said bottom leg and between said long leg and said short leg; a first set member on one of said short leg and long leg, said first set member being adjustably movable toward the other of said short leg and long leg; a second set member on one of said bottom leg and said support arm, said second set member being adjustably movable toward the other of said bottom leg and support arm; a tilt switch; a connector adjustably connecting said tilt switch to said bracket support arm in a selected one of a plurality of secure positions pivoted around an axis fixed to said bracket support arm, said axis being oriented generally transverse to said long and short legs; a circuit status indicator; a wire connector for both said tilt switch and said circuit status indicator; and a plug kit selectively securable to said wire connector to form a selected circuit with said tilt switch and one of a controller and said circuit status indicator. 2. The position detector of claim 1, wherein said first plug includes a power source for said circuit. 3. The position detector of claim 2, wherein said power source is a battery. 4. The position detector of claim 1, wherein said plug kit includes a first plug adapted to include said circuit status indicator in said selected circuit and a second plug is adapted to include said controller in said selected circuit, wherein said controller operates responsive to the condition of the tilt switch. 5. The position detector of claim 1, wherein said circuit status indicator is a light emitting diode. 6. The position detector of claim 5, wherein said light emitting diode is integral with said tilt switch. 7. A position detector for a check valve having a check valve arm pivotable responsive to a change in position of the check valve, comprising: a bracket including a support arm; adjustable securing members adapted to rigidly secure said bracket to said check valve arm; a tilt switch; a connector adjustably connecting said tilt switch to said bracket support arm in a selected one of a plurality of secure positions pivoted around an axis fixed to said bracket support arm, said axis being oriented generally horizontally when said securing members secure said bracket to said check valve arm a circuit status indicator; a wire connector for both said tilt switch and said circuit status indicator; and a first plug selectively securable to said wire connector whereby a first circuit with said tilt switch and said circuit status indicator is formed when said tilt switch is in a selected position, a plug kit selectively securable to said wire connector whereby a selected circuit is formed with said tilt switch and one of a controller and said circuit status indicator. 8. The position detector of claim 7, wherein said plug kit includes a first plug adapted to include said circuit status indicator in said selected circuit and a second plug is adapted to include said controller in said selected circuit, wherein said controller operates responsive to the condition of the tilt switch. 9. The position detector of claim 8, wherein said tilt switch closes said second circuit when said check valve arm is in a position corresponding to said check valve being closed; said controller controls a pump adapted to pump through said valve; and said controller activates a pump operation alarm when operating said pump if said second circuit closes. 10. The position detector of claim 7, wherein said bracket has: a long leg generally parallel to a small leg, said long and small legs interconnected at their lower ends by a bottom leg; and said support arm extends from the upper end of the long leg, said support arm being spaced from said small leg and including a portion facing said bottom leg; wherein said check valve arm is receivable between said support arm and said bottom leg and between said long leg and said short leg. 11. The position detector of claim 7, wherein said securing members comprise: a first set member on one of said short leg and long leg, said first set member being adjustably movable toward the other of said short leg and long leg; and a second set member on one of said bottom leg and said support arm, said second set member being adjustably movable toward the other of said bottom leg and support arm. 12. The position detector of claim 7, wherein said first plug includes a power source for said circuit. 13. The method of claim 12, wherein said power source is a battery. 14. The position detector of claim 7, wherein said circuit status indicator is a light emitting diode. 15. The position detector of claim 14, wherein said light emitting diode is integral with said tilt switch. 16. A method of securing a position detector to a check valve arm pivotable responsive to a change in position of a check valve of a pump, comprising the steps of: securing a support bracket to said check valve arm, said support bracket supporting a tilt switch pivotable about a generally horizontal ads relative to said support bracket; providing a powered circuit through the tilt switch and a position indicator associated with the tilt switch; pivoting the tilt switch while the check valve arm is in a closed position until the position indicator is activated by the powered circuit; securing said tilt switch against pivoting relative to said support bracket; and providing a monitoring circuit through the tilt switch and a controller controlling the pump.
