"We came home to our basement with couple of inches of water. The plumber was able to come that same afternoon and recommended that we replace the sump pump. During the repair, he discussed the need for maintenance on this sump pump. We enjoyed working with this plumber and will hire this company again."

"I couldn't have asked for a better experience. Anthony Jr was very professional and courteous, he was understanding of my kids running around, and he answered all the questions I had. I let him fix the sink while I was busy dealing with my children. He was also right on time for the appointment, and was very prompt fixing the issue. After he was done, he explained again everything he did, collected my Service Fee, and explained that there were no additional costs because it was covered by my home warranty company. In the future, I will definitely use A-total Plumbing! Thank you for your great service!

"Starting with my salesman Stan, who was extremely knowledgeable and patient through an easy installation and then my plumbing Overview by Blake who was extremely thorough it has been great working with this company. Blake even noticed that my recent water heater installation by another company was not up to code so I had to call them to come back. He even went so far as to email me information that I could share with the other company to make sure they change the errors. Whether you need AC or plumbing this is a great company."

"In speaking with Ashley over the phone, I wasn't expecting a free trip charge to evaluate the sewage ejector pump issue and have Jeremy out to the house within 2 hrs. Very cool! Jeremy was excellent at explaining the issue, and replaced our pump. Thx for military discount!! Great customer experience and would recommend you to call Freedom Plumbing when you need them!"

FAQs for sump pump or interior foundation drains installation projects in Dunwoody, GA

Most residential pumps draw approximately 1,300 to 2,900 watts when they first start, then settle at roughly 800 to 1,050 watts during normal operation. The exact number depends on the motor’s horsepower and how often the float switch tells the pump to run. Even at the high end, the electricity cost is minor compared with the expense of cleaning up a flooded basement.

Grab a ruler and an empty 18‑inch‑wide pit. During a steady rain, time how much the water rises in one minute. Multiply that depth (in inches) by 60 to calculate gallons per hour, then add 50% for safety. If the result tops 2,100 gallons per hour—about 35 gallons a minute—you’ll need a 3/4‑horsepower unit. Anything lower, and a 1/3- or 1/2-horsepower pump should do the trick.

Loud rattling, constant cycling, or shuddering vibrations are the pump’s way of telling you it’s on its last legs. Musty smells, higher electric bills, and visible rust are other red flags. If the unit is 10 years old or older and exhibits any of these symptoms, replace it before the next heavy rain turns your basement into a wading pool.

You don’t have to hire a licensed plumber, but you should still bring in someone who installs sump pumps for a living—whether that’s a plumber, basement‑waterproofing specialist, or experienced handyman. They know the local codes, can wire the pump safely, and will test the system before they leave. Skipping professional help might void the warranty and could leave you with a pump that fails when you need it most.

Not every basement needs a pump, but if your home sits in a floodplain, has a high water table, or has ever taken on water during a storm, a sump pump is inexpensive insurance. For basements that only struggle with condensation or the occasional damp spot, sealing cracks and improving drainage may be all that is needed.
