I added to my answer. The whites all get connected together as long as there is only one power source in the switch box (probably is). You will be bringing the white from the existing light over in the 14-2 cable anyway. So yes you can use that white to go to the fan-light circuit.

comment What could be causing my water heater inlet pipe to corrode?
You say the heater is 6yrs old, you should get another 6yrs out of it. Maybe more if you check, replace the anode rod and drain it once a year.

comment What could be causing my water heater inlet pipe to corrode?
Not two devices for the same thing, they both are used together. The nipple is a dialectic on the inside only. You need the union to isolate the currents from the galvanized to copper connection.

comment Network Garage Door opener/ how does the switch work
@TomG- I believe mine is current sensing, by using different resistances. I remember monitoring the voltage on the pair and it was 18 VDC static. With an accessory button pushed it would drop a volt or two, polarity stayed the same. I did not take apart the control panel so I can't say for sure. If it were diode steering as you suggest, I would think the pair would be polarity sensitive showing only the FV of the diode. If I get time I will take the switch panel apart to see for sure:)

comment Is it safe to splice these cords with tape instead of a terminal?
@UNECS - I can't remember ever seen a double insulated appliance with a three prong plug. One reason for the double insulation is so it does not require a ground. If it did have a ground, I'm sure you should not defeat it. The OP did not state what the load was, therefore I assume it should be grounded.

You could also toe screw it with deck nails.

@Iqlarry - He has a 15A breaker, not a 20A breaker. Didn't you mean to say 1440 Watts resistive?:)
