A method for supplying and withdrawing water to and from a user apparatus is achieved by supplying and withdrawing water through a single water pipe during different periods of time. A remote controlled water flow and drain system for implementation of this water supply and withdrawal method includes a water passage having two ends, one being use with the user apparatus such as a plant pot, and the other being connected to a reversible pump, and is controlled by a main controller, preferably in combination with a remote controller. The system can be connected to both a water source and a place for drainage, selectively communicating with the water source to supply water through the water passage to the user apparatus at one time, and at another time communicating the place for drainage to withdraw water from the user apparatus and deliver the withdrawn water to the place for drainage. In various embodiments and applications of the invention, the system can be made as a central system in a house, an attachable system, or a portable system. The entire operation can be fully programmed.
