• the skid can have rows of friction reducing wheels oriented so that, with the additional feature that the camera is self leveling, the skid functions equally well regardless of its axial orientation.

• video line can run coaxially through the water line and the ends of the lines can be fastened together with a two piece grommet which does not require epoxy. This arrangement simplifies operation by simultaneously:
• a further feature of the invention is that said camera is oriented to be air-blast cleaned due to air flow resulting from the venturi effect of flow in the pipe.
• operation of the device results automatically in cleaning of the camera lens such that the view is always unobstructed, with no effort required on the part of the operator.
