Ever had problems snaking electrical cable through a conduit? Reader Louis Burger shares his clever tip with us.

I had to run a new electrical cable through an existing conduit, but don’t own a snake or fishtape. The length between the sockets was about 15 metres, with multiple bends in between. After repeatedly trying to get a steel cable through the corners of the conduit, I was about to give up.

I hit on the idea of tying a small ball of cotton (slightly bigger than the diameter of the conduit) to reasonably strong fishing line. I tucked this into one end of the conduit and held a vacuum cleaner on the other end. It needed the right size pipe on the end of the vacuum cleaner to get an air-tight fit to the conduit – duct tape can come handy here for sealing it off. In no time the cotton ball was on the other end. I then pulled a thicker fishing line through using the previous one, followed by the new electrical wires.
