Wall outlets go out when raining


Whenever it rains (thankfully not too often in Southern California), the outlets in all three of the bathrooms go out. I can re-set the GFCI (which is in the garage), but the re-setting time can vary. Sometimes, i re-set it right after it trips, and it takes right away (the re-set button doesn't pop back out), other times, I have to wait and keep trying half-a-day to two-days until the re-set works.

The three bathrooms are the only thing in the house that goes out with rain

What should I be checking?

Thank you.

Exterior receptacles. You have some exterior wiring that is protected by the bathroom GFCI, and it is getting water in it and causing a ground fault.

Find the fault.
Offhand I'd say that water is finding it's way in somewhere.

There's rain water infiltrating that circuit somewhere... are there are visible signs of leaking at ceilings, windows or doors? Also, are their any outdoor receptacles or light fixtures attached to this circuit?

That fact that sometimes the GFCI won't reset immediately makes me think you have rain collecting in a junction box somewhere, probably one that is on a outside wall (possibly under a window).

Have you mapped out this circuit so you know exactly junction boxes are affected by the GFCI? I would start by shutting off this circuit, and then opening each junction box and inspecting for signs of recent water infiltration. Once you find, you'll need to fix the source of the leak.

I would say you have an exterior outlet somewhere that you haven't found.
Either that or water is getting inside somehow....if this were the case you probably would have already noticed a leak.

Sometimes they are worse than this.

I agree with this post. Check all outside recepticles.
