What causes a cable to get discoloured?
I have a heating/hot water issue however the cable that comes from the boiler to the pump gets discolored on one side (on the side that connects to the pump). The discoloration can take a few weeks.
This then causes a delay for the heating/water to come on and eventually the heating won't come on. As soon as I strip a bit more fresh copper it works fine.
The cable is 24 years, 4 core blue, yellow, red type.
What is the cause of discoloration? I'm assuming heat?
What is the lifespan of cables.
