Blocking Interference

Have you ever lived in one of those homes where it is difficult to get a nice, hot shower? Where, if someone repeatedly turns on the tap at a sink at the same time, your shower goes from hot to cold and back again? In a sense, that's similar to what happens to a building's power supply when affected by harmonic interference.
