Device to clean, disinfect and unclog kitchen, bathroom sinks drains, garbage disposals and other uses includes a cylindrical body (2), open at its two ends, provided with means for its tight fitting at the outlet (3) of a tap, includes a reducer length (21) of the diameter of the the outlet, the said body (2) being connected in turn, to a flexible pipe (4), also open at its ends, by which distal end (41) the water is expelled under pressure that can be oriented to carry out the cleaning of the sink where the tap is located in the non-accessible areas such as the overflow or the drain. A distal end (41) of the pipe (4) can be blind but incorporates several side holes (43) that radially distribute the pressurized water. A body (2) can include the diameter reducer (21) defines an internal housing (22) adapted to incorporate a bar (5) of detergent or other chemical.

A jetter nozzle has a body with a plurality of orifices opening to an exterior of the body and adapted to release a pressurized liquid from an interior of the body, and a sleeve extending from one end of the body. The sleeve has an internally threaded portion adjacent to the body and an unthreaded portion adjacent to an end of the sleeve opposite the body. The threaded portion is adapted to engage with some external threads of a hose fitting. The end of the sleeve is adapted to be positioned adjacent a wrench face of the hose fitting and to reside over other external threads of the hose fitting.

An overflow vent irrigation device is disclosed. An example overflow vent irrigation device includes a reservoir body having an input port and an exit port. The example overflow vent irrigation device also includes a tablet chamber in fluid communication with the reservoir body, and a turbulence dam within the reservoir body. The input port is connected to a faucet of a basin, and the exit port is connected via a hose to an overflow port of an overflow-to-drain journal of the basin during use to clean the overflow journal of the basin.

There is disclosed a method and apparatus for finishing an internal channel of a component. The method comprises installing the component in a flow circuit which is configured to drive a fluid flow through the internal channel and controlling the fluid flow through the internal channel so that cavitation bubbles are continuously generated by a hydrodynamic effect to erode the internal channel by implosion of the cavitation bubbles. The fluid flow may comprise abrasive media which may abrade the internal channel.

A plumbing insert cleansing device having a mounting plate, a nozzle, a solution port, and a hose is provided herein. The cleaning device is configured to permit for the pressurized cleaning and clearing of debris through a cleanout in the waste pipes of a structure. The mounting plate has a plurality of apertures and is configured to fit within the cleanout. The nozzle is coupled to a first aperture in the mounting plate and the solution port is coupled to a second of the apertures. The hose is separated between the solution port and the nozzle. Water enters through the nozzle and a cleaning solution enters through the solution port. They are mixed downstream prior to exiting at a higher pressure.
