Abstract

A drain cleaning tool includes a wear indicator for providing a visual indication to a user of the tool of an amount of wear in the tool. Various forms of the wear indicator and tool include a flexible plumbers cable with one or more wear detector prominences extending between turns of the cable, a tool carried on the end of the cable and couplings on the opposite ends of the cable. The flexible plumbers cable includes an elongate hollow outer body member defining a longitudinal axis and a resilient intermediate body carried within the outer body. The resilient intermediate body carried within the outer body has along its periphery at least one wear detector prominence extending radially outwardly between at least one selected turn of the helically coiled outer body. The at least one wear detector has at least one color change in the radial direction to provide a visual indication visual indication to a user of the tool of an amount of wear in the tool. Further, a tool on an end of a flexible plumbers cable includes a wear detector. A flexible plumbers cable section includes an elongate cable portion, first and second coupling portions on opposite ends of the cable section, and a wear indicator on the coupling portions.
