Abstract
Apparatus for flushing a drain pipe with an accessible open end has a valve assembly with a hollow body connectable to a source of liquid under pressure for the supply of liquid under pressure to the interior of the hollow body, the hollow body having an open end positionable in communication with an open end of a drain pipe. A valve member is mounted for sliding movement in the valve body between a closed position in which the valve member prevents flow of liquid under pressure from a source thereof through the hollow body to the open end thereof, and an open position in which the valve member permits flow of liquid from the source thereof through the hollow body to the open end thereof. An actuating portion of the valve member is manually engageable to move the valve member by manual pressure to the open position against the action of a spring, when the open end of the hollow body has been positioned over the open end of a drain pipe and the hollow body has been connected to a source of fluid under pressure. The valve assembly is held against the open end of the drain pipe by the manual pressure and liquid under pressure from the source thereof flows through the hollow body into the drain pipe to flush undesirable matter therefrom and/or to dislodge blocking material in the pipe.
