The guarantee covers for the advertised period, all manufacturing defect. It does not cover products failed due to 3rd party issues such as the following examples.
Tap has started to leak and will not shut off. a foreign object such as sediments from the water pipe has entered the tap cartridge and has lodged and forcing the tap not to close 100%, this will not be covered by the guarantee as the fault is not caused by the tap but of the foreign object entering the tap cartridge resulting in malfunction.
The tap has discolored over the years. Tap may be placed near a window where the sun can help discolor the tap over a period of time, this will not be classed as manufacturing fault as the same tap positioned away from the window will not discolor in the same rate, this will be classed as wear and tear and not manufacturing fault.
