Abstract

A freezeless wall hydrant is provided that has an elongated inlet pipe comprised of a hollow tube. The tube is connected to a valve and fitting assembly on its inner end for connection to a source of water under pressure. On the outer end, the tube is connected to an adjusting element with an outlet port that is associated with the valve and fitting assembly to open or close the tube to fluid flow and allow for fluid flow out of the tube when the valve is in the open position. The tube is comprised of a flexible material that enlarges in diameter in an area along its length when it is subjected to trapped fluid therein under high pressure so that the tube will not rupture. The tube returns to its normal diameter after the high fluid pressure therein is abated.
