Abstract
A dry (unpressurized) hydrant utilizes a hydrant pipe formed from PVC. One end engages a sliding swivel mount attached to a post with the other end of the pipe being free to swing and to be placed within a nearby body of water. The free end may include a strainer assembly, also formed of a PVC material. The strainer end may be placed at a predetermined depth within a body of water, such as a lake, pond or the like, by means of a second support located proximate the body of water. Alternatively, the strainer end of the hydrant pipe may be provided with a buoyant float to maintain the level of the strainer end of the hydrant pipe just below the water surface. In another embodiment, the strainer end of the hydrant pipe is provided with a rotating wheel assembly which enables the strainer end of the hydrant pipe to be rolled into position beneath the surface of the body of water. The dry hydrant is formed from inexpensive and lightweight materials and can be stored dry when not in use.
