The improved plumbing P-trap is a plumbing fixture. The improved plumbing P-trap attaches the drain of a sink to a DWV. The improved plumbing P-trap transports gray water into the DWV from the sink. The improved plumbing P-trap comprises a modified P-trap, a second clean out plug, and a snake guide. The modified P-trap transports gray water from the sink drain to the DWV. The second clean out plug is the modification to the modified P-trap that provides access to the DWV side of the modified P-trap. The second clean out plug is intended for use with a plumbing snake. The snake guide: 1) opens the second clean out plug; and, 2) attaches to the second clean out plug to guide the plumbing snake into the DWV.

A toilet protective overlay device assembly, comprising a body for fitting over a toilet bowl rim, sized to the approximate dimensions of the outer edge of the rim to overlap the rim, the body having a top side and a bottom side. The body includes plurality of openings to receive a clamp having a non-mar surface in contact with the rim, with a plurality of clamps positioned individually through the openings to secure the body to the toilet rim, and clamps able to move within the openings to adjust the fit of the body on the rim. A flexible hose is connected so as to provide a conduit through an opening in the body, with the conduit passing from the top of the body past the bottom of the body, with a portion of the flexible hose inserted into a toilet fixture trap.

A hand tool and related method is provided for breaking up solid waste in a toilet. The hand tool comprises a base shaft connected to a handle shaft at an angle suitable for reaching into a toilet bowl to break up solid waste thus preventing clogs. The base shaft includes a first tip, which has a rigid wing extending laterally out from the end of the base shaft.

Various assemblies for indicating movement and direction of drain cleaning cables used in plumbing tools are described. Generally, the plumbing tools include a cam that is in operable engagement with a guide tube. Upon axial movement of cable relative to the tool, the cam causes reciprocal movement of an indicator. The plumbing tools can additionally include switches and/or electronics in communication with the indicator to thereby provide information or processing of tool operation.

Methods and devices for the execution of core drillings in a material by a drilling unit, which makes use of a drill bit, and such drill bits that are made up of a hollow cylindrical core barrel, which has an end plate at its rear end and abrasion elements, which serve the abrasion of material, at the front end as well as at least two high-pressure jet nozzles, which can be connected with a high-pressure source of a blasting medium. The high-pressure jet nozzles are arranged on the inner surface of the core barrel and/or its end plate and are oriented into the inside of the core barrel. As a result of a combined forward motion and rotation of the drill bit, a drilling core is formed from which an abrasion takes place by means of the blasting medium, whereby overburden is removed from the drill bit.

Devices and methods for sewer system cleanouts such as provide increased cross bore safeguard during sewer system cleanouts. A sewer system cleanout safety device includes a housing for placement at a sewer cleanout opening to prevent passage of gas out through the sewer cleanout opening during the sewer system cleanout. The housing includes opposed inner and outer cleanout opening surfaces, and a peripheral surface extending between said inner and outer cleanout opening surfaces. The housing includes a cavity extending between the inner and outer cleanout opening surfaces to permit passage of a sewer system cleanout implement therethrough. The housing further includes a cavity lining surface to seal with the sewer system cleanout implement passing therethrough.

A pipe tool positioning system for efficiently inserting, positioning, and orienting a tool for use within a pipe. The pipe tool positioning system generally includes a sleeve with a receiver opening adapted to receive and removably retain a tool such as a grinder or the like. The sleeve includes radially-offset bladders extending outwardly from its outer surface. Each of the bladders may be individually inflated and/or deflated to aid in positioning of the tool within a pipe. A control unit may be provided with controllers for individually controlling each of the bladders. A camera may also be included adjacent to the sleeve to feed a display included with the control unit. By utilizing the present invention, various tools may efficiently be inserted and positioned for use within a pipe.

A drain cleaning cable for use with a drain cleaner. The drain cleaning cable includes an inner core having a first end and a second end, and an outer wire concentrically surrounding the inner core, where the outer wire is helically wound in a first direction to form a plurality of consecutive coils, and where the outer wire has a first end and a second end. A first connector engages with the first end of the inner core and the first end of the outer wire, where the first connector is configured to attach the drain cleaning cable to a drain cleaning element. The second end of the inner core and the second end of the outer wire are received within the drain cleaner.

The invention relates to a cleaning device for internal cleaning of drain or sewer pipes comprising at least one chain comprising several chain links, two end parts, to one of which one end of the chain/chains is/are fastened and to another of which another end of the chain/chains is fastened, which end parts each comprise a central opening, through which a rotatable element extends. At least some of the chain links of at least one chain of the cleaning device have substantially rectangular outer form having at least one right-angled corner and that these chain links are of hard metal. The invention also relates to a method of manufacturing a chain for the cleaning device, in which the chain links are made by cutting from a hard metal plate, for example by laser cutting.

A sewer line root cleaning and repair system includes a root cleaner having a first body and a second body connected by a flexible connector. A flexible rotating member extending from a pneumatic motor in the first body extends through the flexible connector and the second body. The flexible rotating member terminates beyond the second body in a series of bristles. As the root cleaner moves through a sewer line a set of wheels on the first body extends outward, centering the first body in the sewer line as the bristles spin at high RPM centering the second body in the sewer line and scouring the sewer line free of roots including small root hairs. Afterward, a coating sprayer is inserted into the sewer line, connected to a coating supply and air supply, and the coating is sprayed under pressure to line the inner surface of the sewer line.
