"Tommy B was efficient and courteous. I knew who to expect since I got the name and a photo of the plumber in a text. He covered his shoes upon entering the home. He gave the price for parts and labor upfront. He replaced my old sump pump with a new Zoeller Sump pump. As he was working he patiently answered my questions. He cleaned the work area thoroughly. Excellent job."

"Very well. The pipe had a pinhole leak in a copper elbow joint and required cutting the pipe, in a confined space, to drain standing water. G**** Miranda did a remarkable job repairing the pipe and an adjacent supply pipe I elected to have repaired in case its joint might leak. Workmanship was exceptional, potential mess and additional Sheetrock damage was minimized, G**** Miranda worked tirelessly for 3 hours and produced a satisfactory repair."

"As part of our service plan, we had our plumbing systems inspected. To make sure we were safe in the future, I had the technician drain the water heater and install an alarm in case of flooding or system failure. Everything went well and I highly recommend FH Furr."

"They were going to install a ceiling fan I had purchased, but when he came out, he said it would be an additional $250 to install the electrical box. We had already discussed the fact that it didn't have a box prior. so there was just bad communication."

"I donâ t know where to start. Andy Clark and Bruce Crane along with four other guys came to my home for a septic pipe that broke underground. Those guys went above and beyond. I donâ t believe any other guys or company would have did this job for the price they gave us. Thank you so much for your professionalism and knowledge. It had to be over one hundred years of experience in the ground working in my backyard. They fixed a major backup messy nasty issue and I just canâ t thank them enough. For ALL my plumbing needs John C Flood is the best. Thanks fellas!"

FAQs for sump pump or interior foundation drains installation projects in Manassas, VA

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.
