A back-blush cleaning container may have a spring-biased piston that allows the container to fill with hot water when attached to a group head of the espresso machine. When the hot water of the espresso machine is turned off, the piston due to the spring urges the hot water out and back through a 3-way valve to clean the espresso machine. The backflush cleaning container also may have a steam conduit that allows steam from a steam wand of the espresso machine to clean the group head, 3-way valve and tubes. Moreover, the container may have a window which based on the position of the piston, a particular color is shown. The colors indicate whether the container is safe to remove from the group head of the espresso machine and when the container is full of water.

A novel cleaning container is disclosed for backflushing and hence clean an espresso machine. The container may include a body having a top, an opposing bottom, and an interior cavity for holding water, detergent, and/or other cleaning fluid. A piston is slidably disposed within the interior cavity between up and down positions, wherein the piston and an opening of the body at the top define a variable volume for cleaning the machine. A spring is seated firmly within the body underneath the piston for biasing the piston to the up position. A stopper disposed about the top of the piston limits the motion of the piston at the top of the body. One or more grooves within the body are in fluid communication with one or more outlets to permit fluid to exit the body during cleaning. The body may be transparent or translucent.

Devices for cleaning a tube or clearing a blockage from a tube, such as an enteral feeding device are provided. The devices include an actuator and a syringe. The actuator is releasably attached to the syringe in a manner that allows the actuator to transition the syringe from a compressed position to an extended position, and vice-a-versa, without requiring the intervention of a user. A method of cleaning a tube or clearing a blockage in a tube is also provided. The tube cleaning device is filled with a liquid and the actuator pushes the liquid from the syringe into the tube when transitioning into a compressed position, and withdraws the liquid back into the syringe when transition into an extended position, causing the liquid to contact a blockage, and clear the blockage and/or clean the tube.

A contaminant-flushing machine for removing contaminants from a container, such as an engine transmission, air-conditioner coil, or transmission cooler, which includes hoses for coupling to the transmission cooler and a pump for circulating fluid through the hoses and the transmission cooler, the flushing machine being configured to terminate all circulating of fluid when a pressure drop is detected during times when the fluid is circulating only in the primary flow direction, but not when the flow direction is being reversed.

A method and system for removing debris from drainage lines in high rise building uses a high pressure water line terminated by a head having one or more backwards-facing nozzles. The thrust force creates at the backward-facing nozzle(s) is sufficient to propel the head and water line vertically up a drainage line. An operates can control the head and, with the assistance of a video system used with the head, maneuver the head along the line, into single stack aerator fittings, and into and along horizontal lines connected to the single stack aerator fittings. The force of the water exiting the nozzle(s) on the head both dislodges debris in the drainage line and fittings, and urges it downstream back to the access point where the head was inserted into the drainage line.
