Primary vs. Backup Sump Pumps: Keeping Your Orland Park Basement Dry

Tips And TricksUpdated June 28, 2026

Basement water issues are a fact of life for many Orland Park homeowners. Our region's clay soil and moderate water table increase the chances of seepage, especially during late spring storms or rapid snowmelt. A working sump pump isn't just a convenience, it's home protection. But relying on a single pump can leave you exposed if something fails during a flood.

Why Reliable Sump Pump Protection Matters Here

Homes around Orland Park, especially those built from the 1970s through the 1990s, are set on soils that don't drain quickly. Heavy summer storms or long rain spells can saturate the ground fast, and that water needs somewhere to go. Without strong waterproofing and a solid sump system, it often finds its way into basements and crawl spaces. Clay soil holds onto moisture, putting extra load on sump pits and pumps. If your pump can't keep up, or if it fails, you're at risk for water damage and mold growth.

Primary Sump Pumps Your First Line of Defense

The main sump pump (often called the primary pump) usually sits right in the sump pit below your basement floor. Most homes use a submersible unit or a pedestal pump. Submersibles are quieter and sit at the bottom of the pit, while pedestal models have motors that stay above the water. Either type, if sized and installed correctly, should handle the typical runoff for a single-family home here.

Over time, even the best main pump will wear out. Switches stick. Impellers jam. Motors overheat. Hard water from Lake Michigan can build up mineral deposits, and the constant demand during wet seasons doesn't help. Most main pumps last 7 to 10 years on average. If your unit is older, or if you don't remember the last time it was tested, you could be gambling with a basement full of water.

Backup Sump Pumps Why One Pump Isn't Enough

Main pumps rely on your home's electrical system. Power outages during thunderstorms are common in the south suburbs of Chicago, and they often coincide with heavy rain, the very time you need pumping power the most. That's where a backup system comes in. There are two popular options: battery-powered backups and water-powered backups.

Battery backups are installed alongside the primary pump and kick in automatically if the main unit fails or the power goes out. Most use a sealed deep-cycle battery and can pump thousands of gallons on a full charge, enough for a typical storm window. Water-powered backups use your home's water pressure for pumping. These work even when there's no power or battery, but they don't move water as quickly and require adequate water pressure.

Without a backup system, a single tripped breaker or stuck float can put you at risk. Even with reliable municipal water and moderate pressure, it's not smart to rely on one solution. Our team sees first-hand that a backup pump often makes the difference between a dry basement and a disaster.

Common Warning Signs and Simple Precautions

Most major sump pump failures don't come out of the blue. Homeowners can catch problems early by keeping an eye out for these signs:

  • Strange noises from the pump or motor
  • Excess vibration during operation
  • Frequent cycling (running on and off quickly)
  • Visible rust or mineral buildup in or around the pit
  • Musty odors or damp spots near the sump basin
  • Water remaining in the sump pit when the pump should run

Regularly test both your main and backup pumps by pouring a few gallons of water into the pit. If the float switch doesn't activate, or if you hear odd sounds, it's time to investigate. Check that the discharge line isn't blocked, especially with clay soil around Orland Park. Safe routing away from your foundation is key to preventing water from recycling into the pit.

Smart Sump Pump Maintenance and Upgrades

We recommend inspecting your setup every season. Start with cleaning out debris from the sump pit. Look for corrosion on metal parts and test the float switch. Check battery terminals for backup pumps and replace worn out batteries every 3 to 5 years, even if they haven't failed yet. If you see leaks or deteriorating pipes around your pump, a pipe repair and repiping check is in order. Keeping the sump basin lid closed helps reduce debris and odors.

If you're upgrading, match pump size to your home and local runoff. Bigger isn't always better. Too strong a pump can short-cycle and wear out the motor, while an undersized pump can't keep up in heavy rain. When in doubt, talk to a licensed plumber with local experience.

Backup Is Just One Part of Basement Protection

Reliable sump pumps are crucial, but they're just one piece of keeping your basement dry. Make sure your downspouts and landscaping move water away from your foundation. Old or corroded perimeter drains can create problems. If you notice slow drains or water backing up, you might also need drain cleaning to clear roots or sediment. Leaks in the basement walls or foundation may call for professional leak detection and repair, especially if you see dampness in multiple spots.

If your main or backup pump isn't running as it should, or if stormwater is giving you trouble, our sump pump services offer repair, replacement, and honest advice. During massive storms, if you run into flooding or water heater trouble after a backup, we also handle water heater services for Orland Park homes.

Frequently Asked Questions

We suggest testing your backup pump every month, especially during the rainy season. Pour water into the pit to confirm it starts up. Also check the battery or water supply regularly, and replace backup batteries every 3 to 5 years.

Both protect against primary pump failure, but battery backups move water faster and work regardless of water pressure. Water-powered backups are dependable if you have a reliable municipal water supply, but they can pump less water per minute.

Clear debris from the pit, test the pump by adding water, verify the float switch moves freely, and inspect discharge pipes for clogs or leaks. Many pumps last 7-10 years, but annual checks help you catch problems before they lead to flooding.

Continuous running may mean the float is stuck, the switch is faulty, or the pump is too small for your home. Inspect for debris or obstructions, and consider calling a plumber for a professional evaluation if you can't resolve it quickly.
