Sump Pump Maintenance Tips Keep Your Basement Flood-Free

In houses, both new and old, flooded basements can be a real risk if you have a high water table or experience a heavy rainstorm. Even if you’ve done the right thing and installed a sump pump, that’s not always enough. To make sure your sump pump is doing its job and keeping your basement dry, here are some sump pump maintenance tips you can follow for extra peace of mind.

The Importance of Sump Pump Maintenance

Do sump pumps need maintenance? Of course! Routine sump pump servicing helps ensure the system operates reliably when you need it most, like during heavy rains, snowmelt, or plumbing failures. A neglected pump can fail without warning, leading to thousands of dollars in damage, especially if your basement is finished or used for storage.

A well-maintained pump also lasts longer. The average lifespan of a sump pump is 7 years, but poor upkeep can cut that in half. Taking time to clean, inspect, and test your unit boosts its performance and reduces the risk of failure.

Sump Pump Maintenance Checklist

Following a routine sump pump maintenance schedule — quarterly or biannually — helps catch small issues before they become big problems. Use this sump pump maintenance checklist every few months, especially before rainy seasons:

• Visual inspection: Check for rust, corrosion, or cracks on the pump and power cord. Make sure the power cord is secured with zip ties to prevent slack from falling into the pit and interfering with the float switch.
• Power source check: Make sure the pump is plugged into a working GFCI outlet.
• Float switch test: Pour water into the pit and watch to ensure the float rises and activates the pump smoothly.
• Discharge line inspection: Look for clogs, ice, or blockages in the outlet pipe outside your home.
• Check valve review: Inspect the valve above the pump to confirm it’s working correctly and preventing backflow.
• Alarm or battery system test: If your pump has a backup, make sure it’s charged and functional. Also make note of the battery’s age and replace it before the expiration date.

Cleaning & Clearing Debris Around the Pit

One of the most important steps in how to maintain a sump pump is to keep it clean. Over time, sediment and gunk can collect at the bottom of your sump pit and on the pump’s intake screen (on the bottom). At least once a year:

1. Unplug the pump and remove it from the pit if it’s a removable pedestal type. If it’s a submerged pump, leave it in place.
2. Scoop out debris like mud, rocks, or small toys that may block the intake. Use heavy gloves and/or a wet-dry vac.
3. Rinse the pump with clean water and inspect the impeller for clogs. You may have to do this by “feel” in the case of a submerged pump.
4. Clean the pit walls and floor with a wet vac or sponge.

Testing Your Sump Pump

The simplest way to test your pump? Fill a bucket with water and slowly pour it into the pit. You can also run a garden hose to the pit. The float should rise and turn on the pump. Water should drain quickly through the discharge pipe, and the pump should shut off once the pit is empty. It’s normal for residual water to flow back down the discharge pipe into the pit.

This test not only checks the float switch but also confirms the entire system is working as expected.

Backup System

Don’t forget to test your battery-powered backup system. These are critical during power outages and often fail if not charged or cleaned. Replace the batteries every 2-3 years or as recommended by the manufacturer.

When to Call A Plumber

A licensed plumber can ensure everything is installed and functioning correctly, especially if you’re not sure how far your sump pump should drain or how to handle frozen sump pump drain pipes. Here are a few specific instances where you’ll want a plumber’s help:

• Your pump runs constantly or every 20 seconds.
• You find visible leaks or damaged discharge lines.
• The pump doesn’t activate during a water test.
• You’re installing or replacing a battery backup system.
• It’s been over a year since your last professional inspection.

Regular Sump Pump Maintenance Goes a Long Way

A little attention to your sump pump now prevents a lot of headaches later. Stick to a sump pump maintenance schedule, clean your pit regularly, and test your system before every storm season. Learn to listen for your sump pump turning itself on and the familiar knock of the check valve doing its job. Your dry basement will thank you.

FAQs About Maintaining Your Sump Pump

What type of maintenance does a sump pump need?

Regular checks of the power source, float switch, and discharge pipe are key. Cleaning the pit annually and testing the pump every few months are also essential.

How often should I clean my sump pump pit?

Aim to clean the pit once or twice a year, especially before spring and fall. You may need more frequent cleanings if debris builds up quickly.

How often should a sump pump be inspected?

Inspect it at least once every three to six months. If your area sees frequent storms, increase the frequency.

Can I pour water into the sump pit to test the pump?

Yes! This is the recommended way to test your pump’s float switch and activation system.

How long do sump pumps usually last?

Most sump pumps last 7 years with regular maintenance. Heavy use or poor upkeep may shorten that lifespan.

What should I avoid doing with my sump pump?

Don’t unplug it between storms, don’t ignore strange sounds, and never assume it’s fine without testing. Also, don’t connect it to an overloaded circuit.

Is it normal for my sump pump to run constantly or every 20 seconds?

No. Frequent cycling usually means a stuck float, undersized pump, or high water table. Call a plumber to diagnose the issue.

How far away should the sump pump drain line discharge water?

At least 10-20 feet from your home’s foundation. Farther is better, especially if the yard slopes toward the house.

What’s the most common reason sump pumps fail?

Float switch failure is the top culprit. It can stick, break, or get clogged with debris, stopping the pump from activating when needed.

Should I leave my sump pump plugged in all the time?

Yes. It needs to remain powered at all times to activate during emergencies. Just make sure it's on a GFCI outlet to prevent electrical issues.
