Sump Pumps, Explained
A basin is set into the floor at a low point, often where interior drain pipe ends. The pump sits inside, and a float starts the motor as water rises. A discharge pipe carries the water up and out through the wall, and a check valve on that pipe stops each load sliding back when the motor quits.
The outlet deserves the most thought. It should empty on open ground, well clear of the foundation, and never into the sanitary sewer. Many Pittsburgh neighborhoods are steeply sloped, so water let out uphill can creep back to the wall, and water aimed downhill can land next door. Rules vary by town: Mt. Lebanon, PA, for example, keeps sump discharge at least 10 feet from property lines and off the street. Ask your municipality what applies to you.
Battery backup and a high-water alarm are common extras, since a storm can cut power just as the basin fills. The remnants of Hurricane Ivan dropped a record 5.95 inches of rain on Pittsburgh on September 17, 2004 (Brookline Connection), and 2018 became the city's wettest year on record (CBS).
A sump and a backwater valve do different jobs. The sump handles groundwater; a backwater valve is a one-way flap on the building drain that shuts when the public sewer surges. About 75% of the City's sewer system is combined, so rain and household wastewater share pipes (Pittsburgh Water and Sewer Authority). Where drains face that risk, County plumbing rules require protection, fitted by a licensed master plumber under a County plumbing permit.
What Gets Done
- A first basin. A pit cut into the slab at the lowest spot, often fed by drain pipe.
- A worn-out pump. A unit that sticks or never stops, replaced with one sized to the basin.
- A missing check valve. It keeps pumped water from falling back for a second trip.
- Power failures. A second pump on battery power, plus an alarm that sounds if the water climbs too high.
- A poor outlet. A pipe that empties against the wall or onto a neighbor's lot, moved to better ground.
Price Ranges With Sources
| 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) |
These figures are national; no Pittsburgh-specific source exists. A pump swap in a sound basin costs least; a new pit, battery backup and a long run across a sloped yard cost most. Drain pipe into the basin is priced per foot on top, and any tie-in to a drain is plumbing, priced by a licensed master plumber. See the cost guide or try the cost calculator.
What to Expect, Step by Step
- Notice the timing. After storms, during the spring thaw or most of the year?
- The contractor's visit. The slab, any old basin, the nearest outlet and the ground where the pipe would end get a look.
- A written estimate. Expect separate lines for the basin, the pump's make and model, the valve, any backup or alarm and the outlet's end point.
- Permits and plumbing. Inside the City, the contractor confirms permits with PLI (412-255-2175). Any connection to a drain or sewer pipe belongs to a licensed master plumber with an Allegheny County plumbing permit (412-578-8123).
- A test fill. Poured water should start the pump, run out the outlet and shut the valve.

Quick Answers
Can the sump empty into a floor drain or sewer pipe?
Plan on no. Most suburbs forbid sump pumps on the sanitary line, and any connection to a drain is plumbing work for a licensed master plumber with a County plumbing permit. Most sump lines simply end outdoors, on ground that slopes away from the house.
Will a sump pump stop water rising through my floor drain?
Usually not, because water rising through a floor drain points to a sewer backup, not seepage. In the City, Pittsburgh Water's emergency line is 412-255-2423 (press 1), open 24/7. In a suburb, contact your municipality; ALCOSAN says backups are the local sewer owner's responsibility. Ask a licensed master plumber about a backwater valve.
Why does the sump matter when I sell?
Inside the City, a home can't be sold without an Evidence of Compliance Certificate from Pittsburgh Water's dye-test program, and stormwater hookups to a sanitary sewer must be fixed first; combined-sewer areas skip the test. Many suburbs run their own sale tests that check sumps. The authority or town, never the contractor, decides the result. Dye Testing Team: 412-255-2443.
Services That Often Go Together
