A plug puller device and method for removing a clean-out plug from a drain clean-out and permit draining of a drain line below an obstruction prior to removing the obstruction. The device includes first and second housings. The first housing includes a drain connected to its interior. The first end of the first housing is adapted to be removably attached to the clean-out. The first end of the second housing is removably attached to the second end of the first housing. A rod is slidably received in an opening at the second end of the second housing. A fitting is attached to a first end of the rod for coupling and uncoupling with the plug through movement of the rod. A second end of the rod forms a connector to which a tool can be coupled to rotate the rod.

The clean-out plug puller device according to claim 1, wherein the closing means comprises a wiper removably secured within the second housing adjacent the second end of the second housing, the wiper defining an opening having an axis that coincides with the axes of the first and second openings of the first and second housings, the wiper engaging a periphery of the rod to form the fluidic seal therewith. 3. The clean-out plug puller device according to claim 1, wherein the first end of the first housing has female threads for removably attaching the first housing to the clean-out and form the fluid-tight seal therewith. 4. The clean-out plug puller device according to claim 1, wherein the second end of the first housing and the first end of the second housing have mutually engageable threads for removably attaching the second housing to the first housing and form the fluid-tight seal therewith. 5. The clean-out plug puller device according to claim 1, wherein the first connector of the rod comprises a socket. 6. The clean-out plug puller device according to claim 5, further comprising an adapter having a first end engageable with the socket of the rod and an oppositely-disposed second end engageable with the tool so as to enable the tool to rotate the rod through the adapter. 7. The clean-out plug puller device according to claim 6, wherein the second end of the adapter comprises a shaft adapted for coupling with a socket or jaws of a wrench. 8. The clean-out plug puller device according to claim 1, wherein the first connector of the rod comprises a shaft and the fitting comprises a socket adapted for coupling with the shaft. 9. The clean-out plug puller device according to claim 8, wherein the shaft of the first connector comprises a spring-loaded ball detent mechanism for retaining the fitting on the rod. 10. The clean-out plug puller device according to claim 1, wherein the fitting comprises a socket adapted for coupling with a boss on the clean-out plug. 11. The clean-out plug puller device according to claim 1, wherein the fitting comprises a shaft adapted for coupling with a socket on the clean-out plug. 12. The clean-out plug puller device according to claim 1, further comprising a second fitting adapted to be connected to the first end of the rod with the first connector, the second fitting comprising a drill bit socket adapted to selectively couple and uncouple with drill bit. 13. The clean-out plug puller device according to claim 1, wherein the second opening of the second housing is smaller in cross-section than the first opening of the second housing. 14. A method of removing a clean-out plug from a clean-out of a drain line to permit draining of the drain line below an obstruction in the drain line prior to removal of the obstruction, the method comprising: providing a clean-out plug puller device comprising a first housing having a first end adapted to secure the clean-out plug puller device to the clean-out, a second housing attached to the first housing and adapted to close an opening at a second end of the first housing, and a rod that passes through an opening in the second housing such that a first end of the rod is within the clean-out plug puller device and a second end of the rod is outside the clean-out plug puller device;securing the clean-out plug puller device to the clean-out by securing the first end of the first housing to the clean-out so that the clean-out plug of the clean-out is disposed within an interior of the first housing;engaging the clean-out plug with a fitting removably coupled to the first end of the rod;removing the clean-out plug from the clean-out by rotating the rod with a tool coupled with the second end of the rod;draining sewage below the obstruction within the drain line through a passage defined by and within the clean-out, the first housing, and a drain of the first housing;removing the second housing and the rod from the first housing to expose the second opening of the first housing; andpassing a clean-out tool through the second opening of the first housing, through the first housing, and through the clean-out to remove the obstruction from the drain line. 15. The method according to claim 14, wherein the first housing is secured to the clean-out with threads at the first end of the first housing that form a fluid-tight seal with the clean-out. 16. The method according to claim 14, wherein the second housing is secured to the first housing with threads that form a fluid-tight seal with the first housing. 17. The method according to claim 14, further comprising installing an adapter in a socket at the second end of the rod prior to the step of removing the clean-out plug from the clean-out, and then rotating the clean-out plug by rotating the rod with the tool coupled to the second end of the rod by the adapter. 18. The method according to claim 14, wherein the clean-out plug comprises a boss and the engaging step comprises coupling the boss on the clean-out plug with a socket on the fitting. 19.
