Abstract
An irrigation appliance uses a reservoir which inverts to form a cover and includes a simplified valve in the reservoir as well as a switching mechanism adapted thereto. Liquid delivered to the unit from the reservoir is controlled as to pressure by adjustment on a hand-held device remote from the unit. In the base unit are elements which regulate forward and backward flow in order to obtain outlet pressure control.
