15. The inflatable pool of claim 10 , wherein the first internal wall defines a first substantially cylindrical projection and the second external wall defines a second substantially cylindrical projection positioned outside the first substantially cylindrical projection, the inlet cap is entirely positioned within the first substantially cylindrical projection, and the outlet cap is positioned at least partially within the second substantially cylindrical projection.

16. An inflatable pool comprising: a first internal wall; a second external wall positioned outside of the first internal wall; a floor that cooperates with the internal wall to define a water cavity; and a floor drain in communication with the water cavity, the floor drain including a drainage conduit having an inlet end and an outlet end, the inlet end being positioned in the floor in a location spaced apart from and horizontally interior of the first internal wall, and the outlet end being positioned horizontally external of the first internal wall, an inlet cap positioned over the inlet end, an outlet cap positioned over the outlet end, and a plug, the inlet cap having a truncated cone-shaped body portion having a substantially circular base and a plug-receiving portion having an opening sized to receive the plug to block the passage of water from the water cavity through the drainage conduit, the truncated cone-shaped body portion expanding outwardly from the plug-receiving portion to the substantially circular base; wherein the inlet end includes a conical portion having a wide end and a narrow end positioned between the first sealing plug and the wide end of the conical portion.
