What is a Sump Pump and How Do They Work?
A sump pump is a small but powerful device that prevents flooding by removing water that collects in your basement or crawl space. The pump is in a sump pit, which is usually the lowest point in your home. It turns on automatically when the water reaches a certain level. It then pushes the water through a discharge line and away from your foundation.
If your primary sump pump fails, a backup sump pump can take over to prevent flooding. Together, these systems are your home’s first line of defense against water damage during storms or plumbing leaks.
Sump Pump Repair and Maintenance Services
If your sump pump runs all the time, makes odd noises, or doesn’t turn on, you need a professional repair. Our team quickly finds the problem. It could be a stuck float switch, a clogged discharge pipe, or a worn-out motor. We will get your system working again fast. Not acting fast can cost you. An inch or two of water could cause thousands of dollars of damage up to $20,000 and beyond.
We also offer routine sump pump maintenance to keep your system running smoothly. Regular inspections help identify small problems before they become big ones. During a maintenance visit, we’ll:
- Test the float switch and motor function
- Check and clean the discharge line
- Clear any debris from the sump pit
- Confirm the backup sump pump is operating correctly
A well-maintained pump not only lasts longer but also saves you from unexpected sump pump replacement costs down the road.
Different Types of Sump Pumps
Every home differs slightly, which means not all of these systems have the same quality. The most common types include:
- Submersible Sump Pumps: Installed inside the sump pit and built to handle high water volumes quietly and efficiently.
- Pedestal Sump Pumps: Easier to service and ideal for smaller pits, though slightly louder.
- Battery Backup Sump Pumps: turn on automatically if your main pump fails or the power goes out. They are essential for storms in Central NJ.
- Combination Systems: Offer the best of both worlds, combining a primary pump with a backup in one unit.
Our technicians will walk you through the options and help you find the right model for your home’s needs and budget.
Common Sump Pump Problems
Even the best sump pumps wear out over time. Some of the most common issues homeowners face include:
- The pump runs continuously, even without water present
- The float switch is stuck or misaligned
- The discharge line is blocked or frozen
- The pump isn’t powerful enough for the volume of water entering the pit
- The backup isn’t activating when needed
If you’re noticing any of these signs, don’t wait for the next storm. A quick sump pump inspection can save you from major headaches and costly repairs later.

Got an estimate in 1 day and install 2 days later. Everything was amazingly smooth and effortless and our new system is fantastic. Love our new thermostats too. We were very pleased, especially right now when people are having so many problems getting supplies and equipment. Already recommended to neighbors.

Professional & Friendly
Truly great service! He was professional & friendly. He is clearly experienced because he installed a water-pressure sub pump backup system for us which is a complicated job. He came back again a couple of days later to replace an old leaking toilet. He was considerate with cleaning up afterwards too. I highly recommend Guaranteed Services & especially Rob.
