What a Sump Pump Does
The pump sits in a lined pit cut into the basement floor, fed by drain tile or by water pressing up through the slab. As the level climbs, a float switch starts the motor and the water is pushed up a pipe and outdoors. A check valve keeps it from sliding back whenever the motor stops.
Mid-Michigan's glacial till can hold groundwater a few feet under the surface from fall until spring, right beside the walls. About a quarter of Lansing's homes date from 1939 or earlier (Census survey data). Many newer basements in Okemos, MI, Holt, MI and DeWitt, MI came with a sump, yet motors age, floats stick and outlets can ice up or plug.
Pumped water belongs outdoors, on ground that carries it off from your walls and the house next door; a floor drain, laundry tub or sanitary sewer is the wrong destination. Hooking a sump line into any drain or sewer pipe is plumbing, handled by a licensed plumbing contractor under a plumbing permit. A new pump circuit may need a licensed electrician and an electrical permit.
Inside City of Lansing limits, news coverage describes the City's Basement Backup Protection Program (B2P2) as paying back part of what owners spend when a licensed plumber, with a permit and a City inspection, puts in a backflow-prevention valve or sump pump system. It is the City's alone: check its terms on the City's B2P2 page and apply before work begins; see the Michigan rules page.
Common Situations
- No pit yet. Water creeps in at the floor edge with nowhere to gather, so a basin is cut into the slab.
- A tired pump. It hums but moves nothing, never rests, or clicks on and off every few seconds.
- Outages in storms. A battery-powered second pump and a high-level alarm keep watch when the electricity drops.
- An iced-up outlet. A frozen or packed discharge pipe sends water back toward the pit.
- A hose into a drain. A line to a floor drain or laundry tub needs a new route outdoors; pipe connections belong to a licensed plumbing contractor.
What Happens on Job Day
If a contractor accepts the work, a pump job usually goes in this order:
- Terms and permits first. The signed agreement names the pump, basin, valve, backup and discharge point. In Lansing the contractor checks the scope with the Building Safety Office (517-483-4355); towns have their own offices, and sewer tie-ins wait for a licensed plumbing contractor's permit.
- The pit. Slab is broken out where water gathers, a liner goes in on stone and fresh concrete closes the gap.
- Pump and line. The pump, check valve and pipe go in, with the line run through the wall to the yard.
- A trial run. A bucket poured into the basin should trip the float.
What It Usually Costs
| 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, with no Lansing or Michigan price source behind them. Replacing a pump costs less than breaking the floor for a first pit, and a licensed plumbing contractor prices tie-ins and backwater valves separately. See the cost calculator or the cost guide.
Why Start With One Request
One form spares you hunting through firms; sending it costs and earns you nothing. Behind it is a referral and advertising site, not a contractor, plumber or electrician, with no Michigan license for residential building, maintenance and alteration work or plumbing. Contractors may pay it a flat advertising fee, on a free trial at the moment.
Michigan licenses this trade, so check the contractor's license number yourself in LARA's online license lookup, ask for insurance certificates and recent customers, and let payments follow the work.
Quick Answers
Where should sump water end up?
Outdoors, on ground that slopes it away from your foundation and from the homes beside you, never into a floor drain, laundry tub or the sanitary sewer. This site cites no local discharge rule, so if the spot isn't clear, ask a licensed plumbing contractor or the city or township office for your address.
How does a sump differ from a backwater valve?
A sump handles water from the soil beneath the floor. A backwater or backflow valve is a flap on the sewer pipe that closes if sewage heads toward the house; fitting one is plumbing for a licensed plumbing contractor with a permit. At a City of Lansing address, report a floor-drain backup to the Operations and Maintenance Division, (517) 483-4161, a line the City lists as open 24 hours.
Is a battery backup worth it?
Often, because downpours and outages can coincide. In early April 2026 the Lansing State Journal reported National Weather Service flood warnings on three local waterways, Sycamore Creek in Delhi Township among them, and flooded basements around the area. A spell like that is a cue to test the pump.

A pump moves only what drain tile delivers, so read basement drainage and full basement waterproofing too; one wet patch may fit basement leak repair or foundation crack repair.
