A multi-purpose automatic filing basin is provided for containing a selected amount of water which is used for various purposes. The water may be transferred from the basin by wicks or by a pump to water using devices such as plant pots or toys or may be provided for direct use from the basin for devices such as animal feeders and habitats. The basin is kept supplied with water from a pressurized source by a specialized valve which opens in response to a drop in water level below a first selected level and closes in response to the water level reaching as second selected level.

[ We claim:] [1.] In a self-watering system comprising an open top water holding basin having a bottom and a side wall and adapted for receiving from a source thereof and holding therein a desired volume of water; a water using attachment adapted for mounting on top of the basin; mounting and locking means for mounting and locking the water using attachment on the basin; means comprising a water conduit for transporting water from a source thereof to the basin; means comprising a fill valve for filling the basin with water to a selected water level line which leaves air space above the surface of the water when the basin is filled with a volume of water to the selected water level line; and water transfer means for transferring water from the basin to the water using attachment when the latter is mounted on the former; the improvement wherein:(a) the water holding basin comprises:(i) an axially positioned port in the bottom thereof providing access into the basin for water transported to the basin from the source thereof by the water conduit;(ii) seating means on the interior surface of the bottom thereof for axially positioning and water tight securing and mounting the fill valve onto the interior surface of the bottom of the basin over the port in the basin;(b) the fill valve is an adjustable diaphragm fill valve which is either water tight mounted or adapted to be water tight mounted on the seating means on the interior surface of the bottom of the basin and is adapted for maintaining the volume of water in the basin at the selected water level line which is above the top of the fill valve when mounted on the basin, which diaphragm valve comprises:(i) a water inlet port adapted for water tight connection through the port in the bottom of the basin to the water conduit and for receiving water from a source thereof under pressure;(ii) a water outlet port for dispensing into the basin water received from the inlet port thereof; and(iii) a gas port for maintaining the diaphragm of the fill valve at ambient pressure when accessed to ambient air;(c) the water conduit projects substantially radially outwardly from the port in the bottom of the basin beyond the side wall of the basin and above the lower edge thereof and is adapted to be connected to a source of water under pressure; and(d) the diaphragm fill valve is connected to a gas conduit for accessing the diaphragm fill valve to ambient air.
