How a sump pump system works in a New Jersey basement Basement cross-section: an interior French drain carries water into a sealed sump pit. A float switch turns on the primary sump pump, which pushes water up the discharge line, through a check valve and out of the house past an ice guard outlet. A battery backup pump takes over if the power fails.

How a sump pump system works: water from your drain system collects in the sealed pit. When it rises, the float turns the pump on and the pump pushes the water up the discharge line and outside. The check valve stops it from flowing back in, and a battery backup pump takes over if the power fails.

What we install

A sump pump is only as good as the parts around it

A working pump needs room for the float to move and a clear route for the water to leave the house.

🔵

Sealed sump pit

Keeps out debris and basement moisture, and ties into your French drain if you have one.

⚙️

Zoeller pump and float

We install Zoeller sump pumps, including the cast-iron M53, and test that the float starts the pump every time.

🚰

Check valve and discharge

The check valve stops backflow. The line carries water outside, away from the foundation, with an ice guard for winter.

🔋

Battery backup

Install or replace

New sump pump installation vs. sump pump replacement

The right job depends on what you have now. We'll look at it for free and tell you honestly what it needs.

New sump pump installation

No pump yet? We find the best spot for the pit, cut the floor, set a sealed sump pit and run the discharge line outside. If you have an interior French drain, we check how it connects to the pit first.

Sump pump replacement

Pump old, noisy or running nonstop? We check the pit, the float, the check valve and the discharge line, so you know whether the problem is the pump or something around it.

Sump pump replacement

When to repair or replace a sump pump

Many sump pumps last around 7 to 10 years, but it depends on the pump and how often it runs. A pump in a wet New Jersey basement can work far harder than one that only runs a few times a year.

Usually time to replace it

The pump is old, noisy or rusted. It runs nonstop and still can't keep up. It has already failed once, or you no longer trust it to get through the next storm.

Sometimes it isn't the pump

A stuck float, a bad check valve or a blocked or frozen discharge line can look like a dead pump. We check those first, so you know what's really wrong before you replace anything.

New Jersey basements

Why New Jersey basements depend on a good sump pump

Heavy rain, spring snowmelt and high groundwater push water toward basement floors across North and Central New Jersey. Older homes with block foundations often take on water at the joint where the wall meets the floor, and the same storms can knock out the power when the pump is needed most.

A sump pump doesn't keep water away from your foundation. It removes the water that collects in the pit and sends it away from your home. That's why the pit, the check valve, the discharge line and the backup plan matter as much as the pump.

Why the install matters

Where sump pump installations go wrong

Most failures come from the setup around the pump, not the pump itself. This is what we check on every job.

📍

Wrong pit location

The pit has to sit where water actually reaches it, and where the discharge line can get out of the house.

📏

Undersized discharge

A line that's too small or poorly routed makes the pump work harder and can dump water back next to the foundation.

🔄

No check valve

Without one, water in the line falls back into the pit and the pump keeps re-pumping the same water.

❄️

Frozen outlet

Standing water in an outside line can freeze in a New Jersey winter. An ice guard gives the water another way out.

Power outages

Battery backup sump pump installation

The primary pump does the everyday work on household power. But storms that bring the most water can also knock out the power, and that's when a pump with no backup stops.

A battery backup is a second pump with its own power source. It takes over if the power goes out or the main pump fails. We also offer water-powered backups, which run on water pressure instead of a battery. We'll tell you honestly whether you need one.

Water still coming in?

Sump pumps and French drains work together

A sump pump only moves the water that reaches the pit. If water is coming in along the walls or the floor, an interior French drain collects it and carries it to the pump.

We install both, so one crew handles the whole system. As a rule, we install one sump pump for every 100 linear feet of French drain, so larger basements may need two.

Questions

Sump pump installation FAQ

How many sump pumps do I need?

As a rule, we install one sump pump for every 100 linear feet of French drain, so larger basements may need two.

What brand of sump pump do you install?

We install Zoeller sump pumps and check valves.

What warranty comes with a sump pump?

The pump carries the manufacturer's warranty. The drain system we install with it is covered by our 30-year limited, transferable warranty.

Do I need a battery backup sump pump?

If a power outage or pump failure would flood your basement, a backup is worth considering, because storms can knock out the power when the pump is needed most. We'll tell you honestly whether you need one.

Why does my sump pump keep running?

A pump that runs constantly or cycles on and off can have a float, check valve or discharge line problem, or it may be undersized for the water coming in. We'll look at it for free and tell you what it needs.

How do I maintain my sump pump?

Test it at least twice a year by pouring water into the pit to make sure it starts and pumps out, and keep the outside discharge clear of debris, snow and ice.

Does a sump pump need a sealed lid?

We install sealed pits because a sealed lid keeps out debris and basement moisture.

Can you replace my old sump pump?

Yes. We replace old and failing sump pumps, and we check the pit, float, check valve and discharge line so you know nothing else is causing the problem.

How long does a sump pump last?

Many last around 7 to 10 years, depending on the pump and how often it runs. A pump that runs constantly can wear out sooner.

Should I repair or replace my sump pump?

If the pump is old, noisy or has failed before, replacing it usually makes more sense. If the pump is fine, the problem may be the float, check valve or discharge line. We'll look at it for free and tell you honestly.

What size sump pump do I need?

It depends on how much water reaches the pit and how far and how high the pump has to push it. We size the system after we see your basement.

Where should a sump pump discharge?

Outside and away from your foundation, so the water doesn't soak back in next to the house. An ice guard helps it keep working in winter. Rules on where you can discharge can vary by town.

How much does a sump pump cost to install?

It depends on whether you need a new pit, the pump, the discharge run and whether you add a battery backup. We give you a free estimate after we see your basement. Call 1-800-957-0075.
