A sump pump is the last line of defense between a functioning waterproofing system and a flooded basement. It runs during every rainstorm, every snowmelt, every spring thaw — and here, that means frequent, heavy use. If yours is running constantly, making unusual sounds, or has never been tested under load, now is the time to act — before the next storm forces the issue. In our area, heavy spring storms and clay soil push pump run-times well above the national average, meaning many pumps in the western suburbs fail before reaching the standard service benchmark.
Signs Your Sump Pump Needs Attention
The pump runs continuously or cycles on and off rapidly without heavy rainfall
You hear grinding, rattling, or humming from the pit — signs of a failing motor or stuck float
Your pump is more than seven years old and has never been tested under load
The pump ran during the last storm but your basement still had water
You have no battery backup and the power has gone out during storms
The sump pit has no lid, allowing debris, radon, and humidity into the basement
Pump Types We Install
Submersible Sump Pumps
The standard for residential basements. Installed inside the sump pit below the water level, submersible pumps are quieter than pedestal models, more powerful for their size, and protected by the water they pump. We install 1/2 to 3/4 horsepower submersible pumps rated for local storm volumes.
Pedestal Sump Pumps
The motor sits above the pit on a pedestal, making it accessible for servicing without pit entry. Pedestal pumps are appropriate for smaller pits where a submersible does not fit, and they tend to be easier to inspect. Trade-off: louder operation, and the motor is exposed to basement air.
Battery Backup Systems
Storms here knock out power. A battery backup pump activates automatically when the primary pump fails or loses power, running on a 12-volt battery that provides hours of protection. We recommend backup systems for any basement where flooding would cause significant damage. A Wi-Fi-enabled backup can also send alerts to your phone when the primary pump fails.
Combination Primary + Backup Systems
The most comprehensive protection. A high-capacity primary submersible pump handles normal storm loads, while a dedicated backup pump on a battery takes over in outages or overload situations. We size both pumps to your pit volume and typical water inflow so neither is undersized when it matters.
Our Installation Process
Pit assessment: We measure pit diameter, depth, and inlet configuration to select the right pump size and mounting.
Pump selection: We recommend the specific model and horsepower appropriate for your basement water volume.
Installation: Old pump is removed, pit is cleaned, new pump is set, discharge line is connected and routed.
Test under load: We fill the pit and cycle the pump multiple times to confirm operation, switch height, and discharge rate before we leave.

Justin was fantastic. Walked me and my wife through the process of the new sub pump WITH the battery back up. (lesson learned). No high pressure sales pitch, just fact's. They team was courteous and professional. Highly recommend.

I would recommend this company for waterproofing! Great communication between all the staff and they addressed my water issue. They ended up putting in a new interior drain tile system in my entire basement with new sump pumps. Connor is great to work with and explains everything thoroughly. Thank you!

Justin was extremely helpful in locating our basement water issues. Their crew did great work — we haven't had a drop since they did the repairs. Thank you Accu-Dry!

Why Accu-Dry
We install pumps we trust. We recommend and install the same brands we have serviced for decades in basements across the western suburbs — not whatever offers the highest margin.
Full system perspective. We assess your drain tile system and pit configuration alongside the pump itself. A good pump in a bad system still fails.
Backup pump expertise. We size backup systems correctly. An undersized backup on a large pit is not protection — it's a false sense of security.
35+ years serving the western suburbs. We have installed and serviced sump systems in thousands of homes across Downers Grove and the surrounding suburbs, and we are BBB-accredited and 5-star rated. We know what our storms require.

Frequently Asked Questions
How do I know if my sump pump is working?
The easiest test: pour a bucket of water slowly into the sump pit until the float rises and the pump activates. It should turn on, clear the water, and turn off cleanly. If it does not turn on, turns on and off repeatedly, or fails to clear the pit, call us.
Do I need a battery backup sump pump?
If your basement has any water-sensitive belongings, finished areas, or an HVAC system at floor level, yes. Power outages and primary pump failures happen most often during the same storms that create the most water. A backup system that costs a few hundred dollars protects thousands in potential damage.
What size sump pump do I need?
Most residential basements in the area are well-served by a 1/2-horsepower submersible pump. Homes with large basements, high water tables, or integrated drain tile systems moving significant volume may benefit from 3/4 horsepower. We assess your pit and system before making a recommendation — not after.
What does sump pump installation cost?
A standard submersible pump installation in the area typically runs $400 to $800 for the pump and installation. Battery backup systems add $300 to $600. Combination systems vary by equipment selected. We provide a written estimate before any work begins.
How often should I test and service my sump pump?
Test it at least twice a year — once before the spring thaw and once before fall rains begin. The bucket test takes five minutes and confirms the float, motor, and discharge line are all functioning. Beyond testing, have the pit cleaned and the pump inspected professionally every two to three years, or any time the pump is running more frequently than usual. A pump that runs constantly during dry periods has a stuck float or a failed check valve — both easy fixes that become expensive if left until the pump burns out during a storm.
