Abstract
Apparatus for temporarily accessing water under pressure comprising access structure having a main outlet and a pilot pressure outlet for containing the water under pressure and water accessing structure cooperable therewith to obtain temporary access to the water under pressure. A main interengaging connection is provided for manually establishing a mechanical connection of the accessing and access structures without establishing communication of the water under pressure through the main outlet. A second interengaging connection is provided for manually establishing a controllable pilot pressure flow path through the pilot pressure outlet to the accessing structure for water under pressure contained within the access structure. A power operated assembly is mounted in the pilot pressure flow path for selectively communicating water under pressure to the accessing structure through the pilot pressure flow path. An assembly is provided for utilizing the pilot water under pressure selectively communicated to the accessing assembly as a power source to establish communication of the water under pressure contained in the access structure with the accessing structure through the main outlet.
