<p>A cable guide (20) according to the present invention, comprises a substantially cylindrical pipe section (21) with a substantially outwardly projecting flange (22) at one end. A channel (25) is formed in the outside surface of the pipe section (21) and extends from a first point (23) at one end of the cable guide to a second point (24) at the other end of the pipe section (21) and further extends through the flange (22). The two opposite ends of the channel are located at different positions around the circumference of the pipe section (21). The channel (25) is sized and configured to provide a passage for accommodating a cable (not shown). The channel (25) forms a ridge (26) on the inside surface of the pipe section (21) which is shaped so as to minimise the disturbance to the flow of waste water through the cable guide and, therefore, to decrease the likelihood of blockages occurring.</p> |
