GFCI Outlet Installation

One of the first things that most people learn about electricity is that electricity and water don’t mix very well. Water is an excellent conductor, and even a small amount of water can conduct an immense amount of current and voltage, causing electrocution and serious injuries or worse. This is particularly troubling in areas where electricity can help us but water might be present, such as in bathrooms, kitchens, or even outside where weather may become a factor.

As such, electrical safety is an ongoing battle and technology has continually evolved to make using electricity around water safer and less likely to cause a serious injury. Today, that technology can be found in ground fault circuit interrupter outlets, or GFCI for short.

Thousands of Happy Customers

This is a great company. I had a water heater installed and never had a better service person. He was informative and did a wonderful job. Very prompt and efficient.


I received an email from All Pro saying my water heater was due for an annual maintenance. I gave them a call thinking I would be scheduling an appointment for a week or two in the future. To my surprise they said they would send a technician right away. Wow, that’s service! He arrived and introduced himself and told me about what he planned to do. It was a pleasure working with him. He was friendly, polite, and terrific with dogs. It was a hot day, a very hot day, and my water heater is in the garage. I felt rather guilty about that but he didn’t complain. He took care of everything and left the area neat and tidy. He even helped me move a couple of the heavier boxes back into place. I’ve used All-Pro for all my plumbing work. They are always timely, helpful and get the job done right.

Thank you for the prompt and professional service. When our A/C stopped working yesterday, I assumed that the 17-year-old compressor was just going to need to be replaced. I looked at reviews for several companies and called some of them. The smaller companies had a wait of a week or more, and the bigger companies seemed to be money-hungry. The reviews online for most companies were scary….horror stories of $25,000 quotes, etc. Since it’s August, I was out of options, resigned to the fact that thousands of dollars would be spent, and in a time crunch, so I called two of the bigger ones, including All-Pro. Since your company was able to send someone the next day, I went with it. (Well, ok, I had another company scheduled in the afternoon so I could compare the two ridiculous quotes…..I did call them and politely cancel..). Your very professional dispatchers called us this morning to let us know that they could send someone even earlier. Yay! The tech was very professional, polite, and friendly. He gave us several options, all of which were far less expensive than I had feared. He was very patient as we asked a million questions. He got our old system back up and running and let us know some things to keep an eye on. Bottom line, less than 24 hours passed between the time I discovered the A/C was broken until the time it was fixed, and at a reasonable price. Thanks ALL-PRO.

-Lisa L.

I was very happy with the job they did! I had been waiting on a plumber from another company all day, just to be called at 4 pm saying they wouldn’t be able to make it. I called All Pro and they said they could send someone over between 5-7, I was so relieved. He showed up around 530, diagnosed the problem, gave me the price and as soon as I agreed, he got to work right away! He was quick and fixed our clogged drain and cleaned up afterward. It was exactly the service and care I was looking for!

What Is a GFCI Adapter?

A GFCI is a protection device designed to protect people against electric shock by essentially acting as a “kill switch” for the electricity flowing through an outlet if it detects a sudden massive burst of current. It does this by monitoring the current flow between the “hot” and the grounded “neutral” conductors. If there’s a surge on the “hot” side but not on the grounded “neutral” side, the electricity is flowing to the ground through a different source, which is usually causing a shock, or spark. Thus, the breaker trips and the safety trigger shuts off the outlet.

The hope is that by cutting off the current, the exposure to high voltage and current is so minimal that it limits the shock to nothing more than a simple jolt that does little to no serious harm or damage.

Outlets equipped with a GFCI are easy to pick out: they are outlets equipped with two buttons: one reading “test” and the other reading “reset.” Believe it or not, you probably have at least one of them installed somewhere in your house already, most likely in your bathroom, kitchen, or in an outdoor location that may be exposed to rain or other weather conditions.

Where Do I Need GFCI Outlets?

While GFCI outlets are a viable safety feature on every outlet in your home, they’re only really necessary in outlets where water or other electrocution hazards may come into play. We’ve mentioned the three biggest areas already: bathrooms, kitchens, and outdoor outlet receptacles.

However, garages and laundry rooms are also areas where a GFCI adapter is a smart idea. Garages are particularly prone to frayed or damaged cords or cables and laundry rooms may deal with wet laundry or even a rare but still possible machine leak resulting in flooding damage.

Finally, any floor-installed outlet should be a GFCI adapter. You never know when someone walking along with a glass of water may trip, fall over, and spill the water, causing the circuit to short and cause a serious injury.

One thing is common with all GFCI outlet wherever you may install them: they need to be tested regularly. To test them, simply press the “test” button and the “reset” button should pop out. If it doesn’t, the GFCI is no longer providing protection and the outlet needs to be replaced. If it does, simply press the reset button back in and it should lock into place to bring power back to the outlet.

Is your outlet not working when you plug something into it? Do you have loose electrical outlet or an outlet that feels warm or appears discolored? Is your outlet sparking?
