when I turn on the cold water tap the lights dim. What could be the cause?

Two most likely causes:
1) You have an electrical water pump in the house which is drawing too much current.
2) There's a short between a copper water pipe and your electricity.
Either way - get it checked by an electrician.

Are you receiving well water? If so the well pump is causing the drop.

Coincidence. Water tap has nothing to do with electrical.
