When a Basement Needs a Sump Pump
A sump earns its place when water reaches the slab faster than the ground can carry it off. Census survey data shows about 54% of City of Rochester homes were built in 1939 or earlier, and their older stone, brick and block walls often seep at the floor edge. In Chili, NY and Henrietta, NY, 1960s and 1970s block and poured basements can hold drain tile that needs a pit to empty into.
A lined basin sits below the floor where seepage collects. As water rises, a float switch starts the pump, which pushes it up a discharge pipe; a one-way valve keeps the column from falling back when the motor stops.
The water should come out on open ground sloping away from your house and the neighbor's, never into a floor drain or sanitary sewer. Monroe County's Sewer Use Law counts sump pumps as inflow and keeps clear water out of separate sanitary sewers without the Director's permission. The City's combined sewers are treated differently, yet the County still advises City homes to disconnect sumps from them.
Hooking a sump line to any pipe, or taking one off a sewer, is plumbing: in the City, a licensed master plumber does it under a plumbing permit, and in a town, ask the building department which license applies. The contractor you hear from handles the pit and pump.
What This Covers
- A first pit where there never was one. The slab is cut, a liner set and a pump fitted, often fed by drain tile.
- A pump that hums, stalls or cycles nonstop. Floats stick and motors wear out; replacing just the pump is the smaller job.
- Battery backup and an alarm. The battery keeps water moving if a summer storm cuts the power; the alarm sounds if the pit fills too far.
- A discharge line that must get through winter. A pipe laid across the yard can freeze, so ask the contractor how the line is protected.
Costs to Expect
| Cost row | Figure | Source (year) |
|---|---|---|
| Typical basement waterproofing project | about $3,000 to $10,000 (average about $5,000) | Fixr national (2026) |
| Interior perimeter drain, per linear foot | $40 to $120 | Fixr national (2026) |
| Sump pump installation | $600 to $2,500 | Fixr national (2026) |
| Epoxy crack injection, per crack | $250 to $1,000 | Fixr national (2026) |
| Waterproof paint or sealant, per sq ft | $1 to $8 | Fixr national (2026) |
All five rows are national (Fixr, 2026); no New York price source was used. A pump swap sits near the low end of the sump row; a new pit with battery backup and an alarm runs higher. A sewer disconnection or a sewer-line check valve is plumbing, priced separately by a licensed master plumber. See the cost guide or the cost calculator.
What Happens on Job Day
- Permits first. Irondequoit lists sump pump work among its permit fee items; in the City, ask the Bureau of Zoning & Permitting (585-428-6526), and elsewhere the town's building department. The contractor, not you, files any permit.
- Opening the floor. The contractor typically cuts out a square of slab where water gathers, digs the hole and sets the basin in gravel.
- Pump, valve and pipe. The pump drops in, the one-way valve goes on, and the pipe runs through the wall to an outdoor outlet.
- Closing up. Concrete goes back around the basin, under a sealed lid.
- A trial run. A few gallons dumped into the basin should kick the pump on.
A Simpler Way to Compare
Your form reaches one independent local contractor. Sending it is free, and nobody pays you or gives you anything for it. Basement Waterproofing Rochester NY is a referral and advertising service with no contractor or trade license; it quotes no prices and installs nothing. A contractor may pay it a flat advertising fee, free for now.
New York issues no home improvement license in Monroe County, so ask for the insurance certificate, references and a local address yourself. For any job over $500, get a written contract signed by both of you that names the pump, basin, discharge point, price and payments tied to stages of the work. Money paid early belongs in escrow or under a bond, and, as a rule, you may back out of the deal until midnight of the third business day after signing.
What People Ask First
How is a sump different from a check or backwater valve?
A sump pump moves groundwater from below the floor to the yard. A backwater or check valve on the sewer line shuts when sewage flows back toward the house; Monroe County suggests those valves and floor-drain plugs for City homes, installed by a licensed plumber. That is plumbing, done by a licensed master plumber under a permit, not part of a sump job.
When should I test the pump?
Before spring melt and again before summer storms. After a dry spell in July 2020, Henrietta firefighters answering flooded-basement calls noted that a downpour is often when people learn their sump pumps have quit (RochesterFirst). Pour a bucket of water into the pit: the pump should start, empty it and shut off.
My sump hose runs into a laundry tub. Is that a problem?
The County asks homeowners region-wide to keep sump water out of sanitary sewers, so the line belongs outdoors. Changing that hookup is plumbing, for a licensed master plumber with a permit.

Because a pump only moves water that reaches it, basement drainage and full basement waterproofing often come with one; a single damp wall may suit basement leak repair or foundation crack repair.
