A blocked sewer unit includes a substantially impermeable barrier having a first side exposed to the interior of a sewage network and a second side, the barrier movable in the direction of the second side in response to fluid pressure on the first side. The blocked sewer alert unit includes a transducer separated by the barrier from the sewage network, the transducer configured to generate an electrical signal when the barrier moves into the dry section. The blocked sewer alert unit includes an alarm circuit configured to convert the electrical signal into a user alert.

The present invention relates generally to cleaning waste collection systems such as but not limited to sewers, sumps, wet wells, collection tanks, digesters, clarifiers, classifiers, etc. and in particular to cleaning and removal of solid and liquid materials therefrom. In another embodiment, the present invention relates to an improved slurry hose and/or pipe for use in connection with cleaning waste collection systems such as but not limited to sewers, sumps, wet wells, collection tanks, digesters, clarifiers, classifiers, etc. and in particular to cleaning and removal of solid and liquid materials therefrom.

Pipe inspection systems including a push-cable, jetter, and camera assembly are disclosed. A jetter nozzle may be configured to spin and/or propel the camera head within a pipe or other cavity. A cutter line may be attached to the camera head to clean obstructions. A sonde may be coupled to a camera head to generate magnetic field signals for use with a buried utility locator to locate a pipe or other cavity into which the camera head is deployed.

A drain cleaning device includes a power unit and a drum assembly coupled to the power unit for rotation by the power unit. The drum assembly includes a base, a cable received in the base that is configured to be fed from the base and rotated to clean a drain, and a cover releasably coupleable to the base. The drum assembly includes a plurality of taper locks releasably coupling an outer peripheral portion of the cover and an outer peripheral portion of the base. Each of the taper locks is moveable between a locked position in which the cover is retained on the base and an unlocked position in which the cover is removable from the base. Each of the taper locks being biased toward the locked position.

A sewer cleaning apparatus which has a hollow cylindrical body propelled by a plurality of water jets with a clam shell opening on the front of the apparatus operated by a plurality of piston assemblies that are attached to the sides of the cylindrical body. The apparatus is propelled by high pressure water ejected from the apparatus in a rearward direction. The high pressure water operates the piston assembly opening the clam shell and provides forward thrust for the apparatus allowing the hollow bucket type object to trap solids inside apparatus.
