Abstract
A freezeless yard hydrant comprises a single length, electrically heated, hydrant apparatus that does not have an underground drain port. The operating mechanisms are located in the outlet head, above ground, to facilitate the assembly, operation and repair of the hydrant. A single length heater is provided to prevent the hydrant and the water supply connection from freezing under the coldest environmental conditions expected where this type of hydrant would be used. Heat conduction through the water directly from the heating element and the casing materials permits a single length hydrant and heater to be used. By using the electric heater to prevent the freezing, the water does not have to be drained out of the hydrant. The use of such a heater also makes the hydrant very simple to construct and operate. No cumbersome reservoirs or expulsion apparatus are needed to draw water out of the hydrant. This results in an efficient and relatively inexpensive mechanism. The outlet of the hydrant is located above ground in the manner of the typical drain-downyard hydrant, allowing for access to a hose, or for other purposes such as filling buckets or open washing. The outlet of the hydrant is equipped with a hose threaded connection that is provided with either one check valve or two check valves to protect the hydrant from backflow at the hose connection.
