<p>A cable guide includes a substantially cylindrical pipe section with a substantially outwardly projecting flange at one end. A channel is formed in the outside surface of the pipe section and extends from a first point at one end of the cable guide to a second point at the other end of the pipe section and further extends through the flange. The two opposite ends of the channel are located at different positions around the circumference of the pipe section. The channel is sized and configured to provide a passage for accommodating a cable. The channel forms a ridge on the inside surface of the pipe section which is shaped so as to minimize the disturbance to the flow of waste water through the cable guide and, therefore, to decrease the likelihood of blockages occurring.</p> |
