Hi S999, if you run your cables parallel to mains cables then you run the risk of coupling in the large transients that occur on the mains when things like fridges/freezers switch off/on. These transients are much larger that the signals on the ethernet cables and will cause the signals to be swamped momentarily, although the ethernet protocol will usually cope with this. In the worst case it is possible that your ethernet ports could be damaged if the parallel run is excessive (many meters). Crossing at rightangles or keeping 6 inches away reduces the coupling to virtually nothing.

Copper pipes should not be an issue unless your electrical wiring is faulty and the only problem with hot water pipes could be damage to the insulation of poor quality cable.
