A well pump extractor, which includes a base rotably supporting a spindle, a pipe guide, and a pipe catch, extracts a well pump from within a well by winding electrical wiring attached to the pump around the spindle. During an extraction, a pipe guide guides the path of water pipe connected to a pump. If the electrical wiring fails mechanically during an extraction, the pipe catch catches the water pipe, which prevents the pump from falling to the bottom of the well.

1. A well pump puller for extracting a well pump from within a well casing that extends from a ground surface to a below-ground point, the well pump having, electrical wiring with a first wiring end connected to the well pump and a second wiring end extending up to the ground surface, and a water pipe with a first pipe end connected to the well pump and a second pipe end extending up to the ground surface, the well pump puller comprising: a rigid base having an engagement element adapted to engage at least one of the well casing and the ground surface, and a base extension extending upwardly, and rotatably supporting a spindle having a rotation element for rotating the spindle, the spindle being adapted to fixably receive the second wiring end;a rigid pipe guide, connected to said base, and having at least one frame element defining an opening, disposed above the well casing, and having a size greater than the water pipe; anda pipe catch having at least one rigid flap, adjacent to the opening, and having a first flap end hingedly connected to said pipe guide and a second flap end having a concave shape, the at least one flap being, biased in a locking position, and moveable between an unlocking position, in which a the respective second flap end is angled upwardly, and the locking position, in which the at least one flap covers a portion of the opening;wherein when the second wiring end is fixably received by the spindle and the rotation element is rotated to rotate the spindle, the electrical wiring is wound around the spindle resulting in a pulling force applied to the electrical wiring, which pulls the water pipe and the pump from within the well casing towards the ground surface, and the water pipe is guided upwardly through the opening with the at least one flap being in the unlocked position, and if the water pipe is subsequently moved downwardly, the second flap end locks the water pipe in a static position by abutting the water pipe and creating static friction in conjunction with at least one of the at least one frame element and a second rigid flap. 2. The puller of claim 1, wherein the engagement element includes a ground engager adapted to abut the ground surface. 3. The puller of claim 2, wherein the engagement element further includes a casing engager adapted to secure said base to the well casing. 4. The puller of claim 3, wherein one of said base and the casing engager includes a securing element, connected to said base, and defining a pair of bolt holes, and the casing engager includes a u-bolt having a pair of threaded ends and nuts, the ends being adapted to respectively pass through the bolt holes with the well casing disposed between the u-bolt and the holes, and the nuts being adapted to respectively engage the ends to secure said base against the well casing. 5. The puller of claim 1, wherein the engagement element includes a casing engager adapted to secure said base to the well casing. 6. The puller of claim 5, wherein one of said base and the casing engager includes a securing element, connected to said base, and defining a pair of bolt holes, and the casing engager includes a u-bolt having a pair of threaded ends and nuts, the ends being adapted to respectively pass through the bolt holes with the well casing disposed between the u-bolt and the holes, and the nuts being adapted to respectively engage the ends to secure said base against the well casing. 7. The puller of claim 1, wherein the base extension includes a hollow portion, and a section of said support element is adapted to slide within the hollow portion while deforming said elastic element. 8. The puller of claim 1, wherein the spindle is cylindrical. 9. The puller of claim 1, wherein the spindle includes a cylindrical portion. 10. The puller of claim 1, wherein the rotation element includes a crank handle adapted to rotate the spindle. 11. The puller of claim 1, wherein the rotation element includes a shank adapted to operably connect to a chuck of a drill. 12. The puller of claim 1, wherein the rotation element includes an electric motor adapted to rotate the spindle. 13. The puller of claim 1, wherein the spindle includes a notch within which the second wiring end is fixable. 14. The puller of claim 1, wherein the spindle is adapted to fixably receive the second wiring end by winding the electrical wiring around the spindle and over the second wiring end. 15. The puller of claim 1, wherein the spindle includes a spindle lock, having a plurality of teeth, and being adapted to revolve with the spindle, anda safety latch being spring-biased to engage at least one of said plurality of teeth so as to prevent the spindle from rotating in one of a clockwise direction and a counter-clockwise direction, and to allow the spindle to rotate in the other of the clockwise direction and the counter-clockwise direction. 16. The puller of claim 15, wherein the plurality of teeth are angled towards the one of a clockwise direction and a counter-clockwise direction. 17. The puller of claim 1, wherein said base includes a wire guide, disposed between the spindle and the well casing, and having a rounded edge against which the electrical wiring slides as the electrical wiring is wound around the spindle. 18. The puller of claim 1, wherein one or more of the at least one frame element has a curved shape. 19. The puller of claim 1, wherein one or more of the at least one frame element is straight. 20. The puller of claim 1, wherein the rigid pipe guide includes a plurality of frame elements defining the opening. 21. The puller of claim 20, wherein one or more of the plurality of frame elements is straight. 22. The puller of claim 20, wherein one or more of the plurality of frame elements has a curved shape. 23. The puller of claim 1, wherein the at least one flap is spring biased towards the locking position. 24. The puller of claim 1, wherein the at least one flap is gravity biased towards the locking position. 25. The puller of claim 1, wherein the pipe catch includes the second rigid flap. 26.
