Abstract: A yard hydrant has an elongated wet pipe with a plunger that seals against the inside of a well casing. Lifting a pivoting handle at the top of the wet pipe lowers the wet pipe which opens a normally closed supply valve. Pressurized water can then flow up the wet pipe and out of a nozzle head mounted to the upper end of the wet pipe. Lowering the handle pulls the wet pipe upward, thereby clearing it from the supply valve which is spring biased to shut off the water supply. The handle has a cam that positively actuates a normally closed anti-siphon valve so that water left in the wet pipe can fall under gravity to a collection chamber within the well casing beneath the piston. Lifting the handle again lowers the wet pipe and forces the water in the collection chamber back up the wet pipe. At the same time, the anti-siphon valve will close and the wet pipe re-opens the supply valve.
