A system for maintaining conduits and pipes after their installation into a pipeline system used to transport material in a fluid or flowable form. The system includes a maintenance tool adopted for use inside the pipe, an umbilical attached to the maintenance tool for pulling the tool through the pipe; and a pluralities of bearings positioned around the umbilical in order to allow the tool to be pulled through the pipe around bends and turns in the pipe.

A combination toilet unblocking/cleaning apparatus for providing both a toilet unblocking and toilet cleaning tool in one convenient unit. The toilet unblocking tool further includes an adjustable auger, a combined tongs, and a detachable rod. Wherein, the adjustable auger includes two drain cleaning cable connected to a slider and slidable held in an elongated sleeve member; and the detachable rod is removably attached to the adjustable auger to form a combined tongs, constructed in such manner that the rod member can be used individually as drain rod. Also, the combination toilet cleaning tool is using the combined tongs as a handle with a plurality of different detachable bathroom accessories. Accessories may include a brush, a plunger, and a scraper; in which the brush, the plunger, and the scraper are configured to be selectively and removably coupled to the combined tongs.

A urinal and pipe cleaning composition and automated dispensing system and method. The composition preferably comprises urea hydrochloride, a thickener, optionally one or more surfactants, and optionally fragrance. Preferably, the surfactants comprise cocamidopropyl betaine and one or more ethoxylated alcohols. The composition preferably has a viscosity allowing it to be dispensed from an automated dispenser and to coat the surfaces to be cleaned to allow sufficient contact time to dissolve accumulated salts and remove stains. A predetermined dose of the composition is dispensed at predetermined time intervals. Different dose amounts and time intervals may be used depending on the level of usage of the urinal, the amount of salt scale, and level of staining.

The invention relates to an apparatus and method for scarifying the interior surface of pipes, such as a sewer pipe. The apparatus comprises a chassis, a carriage coupled to the chassis to reciprocate along a longitudinal axis of the chassis, a shaft capable of indexing rotation coupled to the carriage, and arms extending radially from the indexing shaft and tipped in high-pressure nozzle assemblies. The method comprises positioning the apparatus in a pipe and alternately reciprocating the carriage and indexing the shaft so as to scarify successive longitudinal swathes of the pipe surface until the desired circumference of the pipe section is scarified. The apparatus is then repositioned in the next section of pipe and the method is repeated until the desired length of pipe is scarified. The invention may further comprise a separable propulsion unit.

The cleaning device is for cleaning the inner surface of pipes. The cleaning device has two sleeves on a flexible shaft and chains extending between the sleeves. A forward end sleeve is not attached to the shaft and is biased by a spring on the shaft. The cleaning device can be adapted to different pipe sizes by altering rotation speed of the cleaning device. High rotation speed compresses the spring and moves the chains further away from the shaft to enable cleaning of larger diameter pipes with the cleaning device.

A feed mechanism for use with a drain cleaner includes a frame configured to be coupled to the drain cleaner. The frame including a cable passage defining a cable axis. The feed mechanism includes a plurality of rollers including a translatable roller. Each roller defines a roller axis. The translatable roller is moveable between an engaged position and a disengaged position. The feed mechanism includes a mode selection member coupled to the frame and moveable between a first position in which each roller axis is parallel to the cable axis and the plurality of rollers are configured to spin the cable about the cable axis, and a second position in which each roller axis is non-parallel to the cable axis and the plurality of rollers are configured to move the cable in a first direction along the cable axis.

Drain cleaners are described that include rotatable drums which retain drain cleaning cable. Mounted on the rotatable drum is a motor and optional gearbox for imparting rotation to the drain cleaning cable. The drain cleaners can also include a cable clamp mounted on the rotatable drum. The drain cleaners are configured such that the rotatable drum is free of positional preference regardless of orientation of the drain cleaner.

Apparatuses and methods for cleaning accumulated sediment from storm drain conduits and other large-diameter conduits are disclosed. A nozzle assembly is arranged to deliver a high-volume flow of water at a pressure high enough to loosen sediment from the interior of a conduit and to propel the nozzle assembly and an associated nozzle feed hose upstream within a conduit being cleaned. Water from the nozzle assembly flushes the sediment downstream and is then collected, partially cleaned, and reused in the nozzle assembly. Mud and clay may be left in the water to increase its specific gravity and viscosity. A self-contained portable and mobile system includes a tank and apparatus for removal of high concentrations of entrained or suspended solids, and a pump and conduits for delivering a high-volume flow of water, containing quantities of suspended solids, to the nozzle assembly.
