Battery backup and water-powered backup options are available so a power outage doesn't undo your protection.
An oversized or undersized sump pump both cause problems down the line — short-cycling, premature motor failure, or simply not keeping up during a real storm. We calculate GPH capacity against your basin's actual inflow rather than reaching for a default size.
We check discharge line routing and check valve placement as part of every install, not just the pump itself.
We carry common pump models on the truck so a failed unit can often be replaced the same day you call.
Battery backup add-ons are priced separately and clearly, so you can decide what fits your budget.
We calculate gallons-per-hour pump capacity based on your basin size and typical inflow rate, not a one-size-fits-all recommendation.
We scope every Sump Pump Installation job in person before quoting it, since two properties with the same symptom rarely need the same fix.
We install submersible pumps rated for continuous duty, not the lighter-duty units sold for occasional use.
A battery backup pump kicks in automatically if the power goes out during a storm — exactly when you need it most.
For homes with municipal water pressure, a water-powered backup pump runs without any battery at all, using house water pressure to move basement water out.
A missing or failed check valve lets pumped water flow back into the basin, making your pump work twice as hard for the same result.
Basin lids are sealed to reduce basement humidity and keep debris out of the pump mechanism.
Tell us your pump's age, symptoms, and whether it failed or you're installing new — that shapes what we bring on the visit.
We also check the discharge line route and check valve condition as part of the same visit.
We explain why a given pump size fits your situation instead of just quoting the most expensive option.
We test the new pump under load, including a simulated power outage if a backup system is installed, before we leave.
"Sump pump failed overnight and flooded part of our storage room. New pump was installed with a backup battery before the next storm hit."
— Downers Grove Customer
"Water-powered backup pump has been a good second layer since our power goes out more than we'd like during storms."
— Downers Grove Homeowner
"Appreciated that they actually tested the backup battery under a simulated outage before leaving."
— Downers Grove Customer
"Explained the GPH rating and why our old pump was undersized for our basin — made total sense once they laid it out."
— Downers Grove Homeowner
If the pump runs constantly or your basin overflows during heavy rain, it's likely undersized for your actual inflow rate.
We can walk through battery versus water-powered backup options based on your home's setup.
We can test an existing pump's condition during an inspection rather than assuming it needs replacement.
If a specialty basin or pump size is needed, we'll give you a realistic timeline upfront.
A primary pump runs on household power and handles day-to-day drainage; a backup pump activates during a power outage or primary pump failure.
Yes, every installation comes with a written warranty on both the pump and the installation labor.
