I live in Canyon Country on a good size piece of property. We have a low spot near the back of the yard and we are quite tired of seeing it as a floodplain during the rains.
Rather than trying to bring in dirt and re-grade the area, my handy husband feels that it would be better to put a pump in to pump out the water. You’ve always said that an outside plug needs to have a GFI, and I noticed where both our garage and patio each have GFI plugs.
I need to know if we need to put a separate GFI where the pump is, because we can’t find the answer online or anywhere we’ve looked. Can you help with this?

The answer is no on this one.
A pump doesn’t require a GFI as long as it is grounded. You do have to maintain the equipment and be sure that the cover stays in good shape, though.
GFI are highly sensitive to moisture, and will trip when a slight amount is detected, so if connected to a pump, the purpose of the pump would then be defeated because it would be shut down by the GFI.
Your lid should be secured and only able to be opened by an adult for servicing purposes, so be sure that it is screwed down always, unless being serviced. Now, a different story would be if you were doing something like a bird fountain with a pump. These need to be put onto a GFI, it is a more likely scenario that a child or someone could be injured playing near this, should there be an electrical issue.
In this case, yes, absolutely a GFI is needed.
Good luck with your project.
About a year ago we had a plumbing leak. Our plumbing runs through the concrete so the plumber ripped out the concrete and did the pipe repair.
We put all the hardwood flooring back down and not long after that we noticed a musty smell, one of humidity. Being afraid that the pipe may have broken again, we went out and bought a moisture meter and tested the flooring.
Depending on the day, it is reading anywhere between 14 percent to 20 percent. It’s not showing 100 percent, so we’re not sure that the pipe is broken but these are high end wood floors and we need to get this figured out sooner rather than later.
It doesn’t feel wet but we can smell the humidity and of course it’s worse if we get down on the floor. There are no visible signs that it is wet but the smell and moisture meter tells us that there is an issue.
Do we need to rip out these floors again? How can we be sure that our home will be safe and undamaged?
It sounds like when the plumber demoed the concrete they broke through the visqueen which is a plastic 6 ml or greater.
It’s likely that they made the plumbing repairs but did not repair the visqueen, and the symptoms that you are getting are due to the static pressure of humidity/moisture that is traveling through the concrete. I’ve seen this a time or two and am most certain that this is the source of the moisture.
You have two options: You can either live with it, which I don’t recommend because the moisture is a source for much more damage over the course of time; or you can go back to your plumber and begin the process of holding him accountable.
I do recommend that if you go this route that you document each and every step and use as many photos to state your claim. Hopefully, (the person responsible) will own the error, but you may have a challenge on your hands with this one.
The visqueen is a vital part of the original construction, keeping the moisture from the earth away from the building materials and ultimately, the interior of the homes. When that is compromised, this is a perfect example of what can happen. Given enough time that moisture will do plenty of damage, including potential mold growth.
Unfortunately, this will be a big one to tackle, but ultimately will be worth it.
You may even need to reach out to your insurance so that they can guide you through the process.
Good luck to you.
