To provide a water producing and supplying apparatus capable of being used sanitarily by constituting that water purified by a reverse osmosis membrane filter is re-supplied to the upstream of a pressure pump, and capable of preventing a temperature rise by preventing an excessive load on a motor by operating the pressure pump for a predetermined time period after supplying produced water or the like.

The water producing and supplying apparatus is provided with the pressure pump provided on the downstream of a water supply passage to which water from a water supply source such as waterline is supplied, the reverse osmosis membrane filter connected to the pressure pump, a water pouring passage provided on the downstream of the reverse osmosis membrane filter, and a circulation water passage having one end connected to the upstream of the pressure pump of the water supply passage, and the other end connected to the water pouring passage.
