"Amazing! The crew was on-site within 3 hours of my 8:00 AM phone call to replace my sump pump. My sump pump runs every 15 minutes, on a dry day, so it was critical to get expedited service and Delaware Plumbing Professionals were fantastic! Highly recommend"

"The project was completed seamlessly and Jim and his helpers were competent, hard-working and didn't mind explaining what was going on every step of the way! His years of experience are evident, and make him a great diagnostician and problem-solver. He even went out to buy stone to line the bottom of the trench dug outside of the house to insure that the new pipe would be stabilized underneath! There were a number of things that could have been complications (like tree roots, and breaks in the pipes going to the septic tank), but it was clear to me that Jim would be able to address them, if they did surface. This was the kind of thing that makes a homeowner very nervous, so I was so relieved that I had Jim do this work. Experienced, competent, honorable, and a really nice guy! So glad that I won't have to conduct searches for a plumber in the future!"

"Installation of our system was top notch and professional. 6 months after installation of my system, the salesman, Scott, immediately responds to any questions or issues that I have. Their service is great and the quality of our water is remarkable. We are very pleased and can't recommend Orbit Water / Puronics highly enough!"

"They did an excellent job! I was worried about mold in the basement and they found some, destroyed it completely then water proofed! I've already told my neighbors about this company and I'd hire them again! The crew was very professional and took time to answer any questions I had."

FAQs for sump pump or interior foundation drains installation projects in Nassau, DE

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.
