A Yard Hydrant Made Easy has a riser with a slip connection, called a pitless adapter, attached directly to the side of the riser, below freeze level. The water supply is connected to the outside section of the pitless adapter and a yard hydrant is attached to the inside removable section of the pitless adapter. This hollow riser and slip connection allows for easy removal and replacement of a yard hydrant, without the need of any future excavation, busting of concrete, or tearing up of landscaped areas. A seepage section may be incorporated at the base of the riser to allow a yard hydrant to drain out without ever coming in contact with soil. This prevents any chance of the drain hole, at the base of the yard hydrant, becoming stopped up and causing the hydrant to freeze. A dual check valve backflow preventer may be installed at the base of the hydrant. An underground shut-off valve may be connected to the outside section of the pitless adapter to allow the individual hydrant to be isolated without interrupting water supply to an entire property.
