Sanitary plunger
The system disclosed herein is directed to a plunger having a protective sleeve for shielding contaminants from the plunger. The plunger includes a handle, and a flexible cup. The body further includes a tab, a shoulder region, a central portion, a first tail, and a second tail. An inlet is disposed on the external surface of the flexible cup. The inlet is coupled to a connector. A through-hole is disposed in the flexible cup or the handle. The through-hole is configured to receive the body of the protective sleeve by passing a portion of the body through an opening of the flexible cup.
MANUALLY OPERATED DRUM-TYPE PIPE CLEANING DEVICE
A drum-type pipe cleaning device comprises a drum rotatable about a rotational axis and a cleaning cable allocated to the drum. A longitudinal section of the cleaning cable extends from the drum. The longitudinal section is rotatable about its longitudinal axis through a rotation of the drum. The drum-type pipe cleaning device further comprises a handle, which is configured to support the drum in a rotatable manner. Furthermore, the drum-type pipe cleaning device comprises a drive shaft for driving the drum and an attachment point allocated to the drive shaft for connecting the drive shaft to a drive unit for drive purposes. A freewheel clutch is provided, through which the drive shaft is or can be connected to the drum in an operative manner such that the freewheel clutch is engaged when the drive shaft is being driven and the freewheel clutch runs freely when the drum is being driven.
SEWER CLEANING MACHINE
A sewer cleaning machine includes a power base with a motor and a drive mechanism, and a drum removably coupled to the power base. The drum includes a cable that is selectively extendable out of the drum and is movable between a first position, in which the drum is supported by the power base and coupled to the drive mechanism, and a second position, in which the drum is separated from the power base.
Submersible pump water jetter
An apparatus and method for cleaning containers using water within the container and a submersible pump exhibiting a nozzle. Air may be injected into the pumped water to increase its pressure as it exists the nozzle.

Automated anti-freeze system for sewer jetter system
An automated system for a jetter system, a method for automatically filling a sewer access system with antifreeze liquid, and a method for automatically recapturing antifreeze within a sewer access system are provided. The automated system may include: a control system configured to provide a normal operational mode, an auto antifreeze mode, and an auto recapture mode; a pump; first and second tanks, and conduits that connect these components. The system automatically fills the conduits with antifreeze liquid from the second tank and then can automatically purge the conduits of antifreeze liquid and return the antifreeze liquid to the second tank for later use in again filing the conduits with antifreeze liquid.

SWITCHER NOZZLE HIGH EFFICIENCY FLOW INSERT
A nozzle assembly includes a hollow nozzle body having a central bore and a plurality of ports extending through the body from the central bore; a switching valve assembly disposed in the central bore that directs fluid flow to ports upon application of fluid flow above a predetermined threshold to the inlet and direct fluid flow to different ports upon fluid flow having subsequently dropped below the predetermined threshold and then exceeding the predetermined threshold; and a flow insert configured to replace the switching valve assembly for directing flow through all of the ports when switching functionality is not needed. This flow insert may be made of a low pressure material such as a polymer.
Drain cleaner
A drain cleaner includes a base unit having a housing, a drive arrangement positioned within the housing, and a motor coupled to the drive arrangement and supported by the housing. The motor is operable to selectively drive the drive arrangement. The drain cleaner also includes a drum unit removably coupled to the base unit. The drum unit has a drum that engages the drive arrangement when the drum unit is coupled to the base unit to rotate the drum, and a cable stored within the drum and selectively extendable out of the drum and into a drain.
CABLE FEED CONTROL MECHANISM FOR DRAIN CLEANER
A drain cleaner including a cable configured to be inserted into a drain, a drum supporting the cable, a first motor operable to rotate the drum, and a cable feed control mechanism configured to feed the cable in a linear direction along a first axis. The cable feed control mechanism includes a second motor, a drive wheel rotatable by the second motor about a second axis that is perpendicular to the first axis, and a driven wheel rotatable about a third axis that is parallel to the second axis. The drive wheel and the driven wheel are configured to engage the cable to feed the cable along the first axis.
