Sump Pump Installation in Greenwich, CT.
Sump systems sized for Greenwich storm volumes. Nor’easters and tropical remnants push the Mianus and Byram Rivers out of bank and pile Long Island Sound surge into coastal village streets in Old Greenwich, Riverside, and Belle Haven. Primary cast-iron pump, battery backup with 7 to 10 hours of runtime on a charged cell, alarm to your phone, discharge below the 42-inch CT frost line.
Free sump-system audit and storm-volume assessment. Written estimate within 24 hours. Most installs complete in one day. Sealed lid keeps soil gases out of the basement air.
- Battery backup standard
- Lifetime pump warranty
- Same-day installs available
Three Greenwich sump-pump triggers
If any of these match your property, the current setup is undersized.
Greenwich storm hydrology is shaped by Long Island Sound surge, two named rivers, and a Backcountry that drains slowly across glacial till on shallow bedrock. A 1/3-horsepower bargain pump is rarely enough on any of those terrains.
No backup pump on a coastal property
Old Greenwich, Riverside, Belle Haven, and Mead Point properties lose grid power during the same storms that push the most water into the basement. A primary pump without a battery backup is exactly the failure mode insurance carriers ask about during claim review.
SCHEDULE A FREE ESTIMATEPump cycles every few minutes during normal weather
If the pump runs every few minutes even when it has not rained, the water table is sitting near the slab. Common on Cos Cob and Riverside properties near the Mianus River and on Backcountry hillsides where lateral groundwater migrates through till.

Discharge that runs above grade or terminates too shallow freezes shut during a hard cold snap. The pump runs against a closed pipe and burns out. Below-frost discharge routing is the fix, sized to the 42-inch CT frost depth.

What makes Greenwich basements different.
Sump pumps in Greenwich earn their keep during nor’easters and tropical remnants that push runoff into the Mianus River and the tidal Long Island Sound shoreline. In Belle Haven and Old Greenwich, where the underlying shallow bedrock and glacial till in the backcountry, with coastal silt and clay closer to the shore drains slowly, a single 1/3-horsepower pump is rarely enough. Our installs pair a primary cast-iron pump with a battery backup that runs 7 to 10 hours on a charged cell, plus an alarm that pings your phone the moment water hits the float. Discharge lines route below frost so they cannot freeze shut in a January cold snap. The pit and check valve sit inside a sealed lid that keeps soil gases out of the basement air.

Greenwich-specific questions
Greenwich sump-pump installation – the questions we get most.
Why do Greenwich coastal properties need battery backup pumps?
Nor’easters and tropical remnants that push the most water into Old Greenwich, Riverside, Belle Haven, and Mead Point basements are the same storms that drop grid power across Fairfield County. A primary pump without backup fails exactly when it is needed. Battery backup with 7 to 10 hours of runtime on a charged cell covers the typical outage window.
How does the Mianus River affect sump-pump sizing in Cos Cob and Riverside?
Properties near the Mianus River corridor see the water table climb during heavy rain even when the river stays in bank. Sump pits cycle more frequently, and the pump has to be sized for sustained run rather than peak burst. We measure the cycle rate during the inspection and size accordingly.
Will the discharge line freeze in a Greenwich January?
Discharge that terminates above grade or too shallow freezes shut during a hard cold snap. We route discharge below the 42-inch CT frost depth so the pump always has an open path. The pit and check valve sit inside a sealed lid that also keeps soil gases out of the basement air.
Are sump-pump installs permitted in Greenwich historic districts?
Sump-pump installation is a basement-interior project that does not typically affect historic exterior fabric. Discharge routing in historic-district Old Greenwich and Cos Cob is coordinated with the Greenwich Building Department to keep exterior appearance compliant; we handle the paperwork end-to-end.
Why CT and NY homeowners pick Big Easy for sump systems.
Why the industry default fails you
Two pumps. Not one.
The industry default is one pump. We install two – a primary cast-iron sump pump plus a battery-backed secondary – as standard. Why? Because the storms that cause the most water are the same storms that knock out residential power.
A single-pump install at half the price is half the protection – gone exactly when you need it most. We won’t sell you that. Battery backup isn’t a luxury upsell; it’s the actual minimum for CT and NY storm patterns. Here is exactly how we install it.
Free pump system audit
We test your existing pump under load. Inspect the basin, check the discharge, measure your home’s water volume. You get a written assessment of whether the system needs full replacement, just a backup added, or honestly nothing right now.
Excavate basin location if new basin needed
If you’re starting from scratch, we excavate at the lowest interior corner – typically a 4-hour task with proper dust control. If you have a working basin, we keep it and upgrade what’s inside.
Install primary cast-iron pump + battery backup
Cast-iron primary pumps last longer than plastic ones in CT’s water-table conditions. Battery backup uses a deep-cycle marine battery, sealed in a vented box, with 12–24 hours of pumping runtime depending on flow.
Run discharge line below CT/NY frost depth
Discharge plumbing routes outside, buried below the 42-inch Connecticut frost line (CT code). It never freezes shut. Daylight outlet positioned away from foundation so discharged water can’t cycle back.
When you don’t actually need a new pump
Sometimes the pump you have is fine. Older pumps that test under load, that you have a maintenance record on, that match your basement’s actual water volume – we’ll tell you to keep them. We make zero on selling you a pump you don’t need. We make a long-term customer by telling you to wait two more years and call us back.
