A Must-Have for Homes in Long Island, Brooklyn, Queens & The Bronx
If you’ve ever dealt with a damp or flooded basement, you already know how quickly water can damage your home. One of the most effective tools in basement waterproofing is the sump pump.
At Waterproofing Experts NY, we install sump pumps across Long Island, Brooklyn, Queens, and The Bronx—especially in areas prone to water intrusion, heavy rain, and high groundwater levels.
In this guide, we’ll break down everything you need to know about sump pumps:
- How they work
- The different types and features
- How to maintain them for long-term performance
What Is a Sump Pump?
A sump pump is a device installed in the lowest part of your basement or crawl space. It pumps out water that collects in a specially dug pit (called a sump pit or basin), keeping your basement dry and preventing water damage, mold, and foundation issues.
Whether you’re in Jamaica, Queens, or Nassau County, Long Island, sump pumps are an essential line of defense against basement flooding.
How Do Sump Pumps Work?
The process is surprisingly simple but highly effective:
- Water flows into the sump pit through drains or natural water movement.
- A float switch or sensor detects the rising water level.
- When the water reaches a certain level, the pump activates automatically.
- Water is pumped out through a discharge pipe and safely diverted away from your home’s foundation.
✅ Sump pumps are especially useful in homes with clay soil, high water tables, or poor exterior drainage—common in many NYC boroughs.
Types of Sump Pumps
There are two main types of sump pumps used in basement waterproofing systems:
1. Submersible Sump Pumps
- Installed inside the sump pit and submerged in water
- Quieter and less visible
- More powerful—ideal for homes with serious water issues
- Typically has a shorter lifespan due to constant water exposure
Best for: Large homes in Long Island or low-lying areas of Queens
2. Pedestal Sump Pumps
- Motor is mounted above the sump pit
- Easier to service and repair
- Less expensive
- Slightly noisier than submersible models
- Suitable for light-to-moderate water intrusion
Best for: Urban homes in Brooklyn or The Bronx where water issues are occasional
Key Features to Look For
When choosing a sump pump for your NYC basement, here are the most important features to consider:
✅ Automatic Float Switch
This sensor triggers the pump when water reaches a certain height—ensuring it activates without manual intervention.
✅ Battery Backup System
During storms, power outages are common. A battery backup ensures your pump continues working even if the electricity goes out.
In boroughs like Brooklyn and The Bronx, where older electrical systems are common, this is a critical feature.
✅ Cast Iron or Thermoplastic Housing
- Cast iron pumps last longer and offer better heat dissipation.
- Thermoplastic models are more budget-friendly.
✅ Alarm System
Some units include alarms that alert you if the pump fails or the water level rises dangerously high.
✅ Check Valve
This prevents water from flowing back into the sump pit once it’s been pumped out.
Maintenance Tips for Your Sump Pump
Regular sump pump maintenance is key to ensuring it works when you need it most—especially during spring rainstorms or Nor’easters.
Here’s how to keep it in top shape:
1. Test It Monthly
Pour a bucket of water into the pit to ensure the float switch activates the pump and drains the water properly.
2. Clean the Sump Pit
Remove dirt, debris, and sediment every 3-6 months to prevent clogs.
3. Inspect the Discharge Line
Make sure the pipe that carries water away from your home is clear of obstructions and extends at least 10 feet from your foundation.
4. Check the Backup Battery
If your unit has a battery backup, test it regularly and replace it every 3-5 years.
5. Schedule a Yearly Professional Inspection
At Waterproofing Experts NY, we offer annual maintenance plans to ensure your system is always ready—especially before the rainy season hits Queens or Long Island.
Do You Really Need a Sump Pump?
Here are signs your home could benefit from a sump pump installation:
- Basement smells musty or feels damp
- You’ve noticed standing water after rain
- Walls or floors show water stains or cracking
- You live in a flood-prone area like certain parts of Queens, Long Island, or low-lying Brooklyn neighborhoods
- Your foundation walls feel soft or flake easily
Remember: Even small leaks can lead to mold growth, rotted wood, and foundation damage if left untreated.
Why NYC Homes Are Especially Vulnerable
Homes in Long Island, Brooklyn, Queens, and The Bronx face several challenges:
- Aging infrastructure and older foundations
- High annual rainfall and storm surges
- High water tables and poor exterior drainage in many areas

That’s why sump pumps—especially when paired with interior basement waterproofing systems—are such a smart investment for NYC homeowners.
