Abstract: A sewer expansion plug for connecting a sewer house to a cleanout pipe that expands a grip ring by rotating a handle. The grip ring includes multiple diameters to accommodate various size blackwater cleanout pipes. The handle connects to a wedge plate, which converts rotational force from the handle into linear movement that expands the grip ring by lowering the wedge plate and pressing slides outward. As the wedge plate moves, it expands a grip ring around the pipe to interface with an interior circumference of the blackwater cleanout pipe. The wedge plate is connected to a base attached to the grip ring to secure the grip ring in place, allowing the pipe to be inserted into the blackwater disposal system.

Abstract: Systems and methods for a hose extension handle system including a tubular grip with distinct first and second ends, a battery carrier within the first end's cavity to hold a battery, and an engageable actuator on the first end's outer surface that is electrically connected to the battery. From the second end of the grip extends a housing including a light source, also connected to the battery and actuator. An upper strap with two extending arms and a lower strap that can be attached to these arms may be configured to secure around a hose. The light source within the housing may be aimed to illuminate the inside of the hose.
