Koi pond in my backyard. I thought both pumps died (they are old so it's possible). Take them out and check them. Reset the GCFI and they did not work. Move them out and check on another outlet, they are running. One pump does trip the GFI as I unplug it. The other did nothing, just ran.

How can I check if the pump is bad and tripping the GFI or if the outlet itself it bad? I'm YouTube Brave now as I have watched enough videos to feel ok changing my own outlets. I plan on buying a breaker locator and plug test kit that can identify if the hook up was poor.

Don't want to waste my time or cash changing out plugs if it is the pumps that are the problem. Conversely I do not want to blow $200-400 on two new pumps and have the same bad outlets?

Trying to avoid an electrician as I know an outlet is a minimal job and I'm gonna pay $200 for 10 mins of work. I just need to know at what point I am over my head.

Plug in something you know works into the outlet to test it.

Won't do any good... depends on what kind of amperage it's drawing

They now make new WR(weather resistant) GFI's. Whatever the problem is I'd recommend you replace the existing with the new.

GFI doesn't have anything to do with overcurrent protection.

As mentioned, I would plug something else into that receptacle that's acting up + try the pump on a non-GFI receptacle.

yeah, this an amp issue

but, in reality, how much money and time is swapping out a GFI? It's cheap and quick. just do it and eliminate it as the easiest solution. If it works, great, job done. If not, then the worst thing you've done is change out an outlet

If you've never changed an outlet before and your first will be a gfci make sure to take a picture of the wires and maybe mark them with a little tape. GFCI for a DIYer cam be tricky. I know I screwed up my first one.

So if I have this straight:

- Both pumps plugged into same GFI, pumps not working
- You inspect, find GFI tripped
- You reset it, pumps still won't work
- You try them on a different GFI and they work, but one pump trips the GFI

If this is all correct, the pump that tripped the GFI is suspect. When you reset the original GFI, did you also check the breaker and other GFI outlets that it may be wired to? Did you test the original GFI with something else?

There are mechanical moving parts in a gfci outlet. Over time they can fail to reset or become over sensitive. No harm in replacing the gfci if you are confident that you can do it safely.

With a new and known properly functioning outlet, it will be easier to troubleshoot the pump motors. Even if the pump(s) are bad, replacing the outlet was still a good thing to do.

as a commercial electrician this thread makes me smile..


First off do you have both of these pumps plugged into 1 GFCI? If so depending on the pump size i wouldn't recommend that, also these pumps usually have a built in ground fault in the plug so this could be a problem

have you noticed any breaker issues?

also how big are these pumps, can you take a pic of the stickers on them or on their power cords?

but if i had to take bets i would say a pump is bad with windings that are 'leaking' current to its grounded housing, creating a ground fault large enough to trip the GFCI


ok that will be $400

Plug something else and preferably of a similar amperage into the outlets. Do the pumps have a sticker that say their amp draw?

Also, plug your pumps on in your bathroom or kitchen sinks. They should be on a gfci also. Make sure you actually have your pumps pump water, not just turn on. Pumping water most likely uses more amps than just actually being on.

Chances are your pumps are going bad, when electrical motors go bad they draw more electricity which can then trip the GFCI.
