"It went very well. Mike was very knowledgeable. He cleared the line and installed a valve that would keep the problem from occurring again. This was after another plumbing firm had given us an estimate for over $800 while Mike fixed the problem and made an improvement for $275. We highly recommend Servant Plumbing."

"Peeples plumbing was so easy to work with they were able to accommodate my schedule and work around a late rescheduling. The tech that came out to install my gas grill was very knowledgeable and instructed me how to swap out the propane orfices for the new gas orfices. He was also very neat and careful not to damage my newly laid sod. I would definitely recommend using Peeples Plumbing and I will call them again for any plumbing jobs I may have in the future."

"Andrew was very prompt and efficient. He provided me options for the water heater repair. He cleaned up very well after he finished the job. When the job was done, he walked me through everything that he completed. Would hire again!"

FAQs for sump pump or interior foundation drains installation projects in Johns Island, SC

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.
