Summer Sump Pump Maintenance Checklist for Greer Homeowners

Greer summers bring a lot of good things. They also bring heat, humidity, and the kind of afternoon thunderstorms that can dump several inches of rain in a short stretch of time. For homeowners with a sump pump, that combination is exactly why summer maintenance matters.

KT Plumbing sees a predictable spike in sump pump calls after heavy summer storms, and a lot of those situations could have been caught beforehand with a basic check. This checklist is designed to help you do that yourself and know when it’s time to call a pro.

Why Summer (Not Just Spring) Matters

Most advice you’ll read focuses on spring maintenance, and spring is a good time. But in Greer, summer thunderstorm season runs well into September, and July tends to bring the most active rain days of the year. A pump that passed a quick spring check can still develop issues by midsummer, especially one that’s been running hard.

If you haven’t looked at your system since spring, it’s worth another look now.

The Checklist

1. Do a Visual Inspection of the Pit

Pop the cover off your sump pit and take a look inside.

• The pit should be free of gravel, dirt, or debris that could clog the pump intake
• There should be no unusual odors (some dampness is normal; a strong sewage smell is not)
• The pump should be sitting upright and level

2. Test the Float Switch

The float switch triggers your pump when water rises to a certain level. It’s one of the most common failure points.

• Slowly pour a bucket of water into the pit
• The pump should activate before the water gets too high
• If it doesn’t turn on, or if it turns on but doesn’t pump the water out effectively, something’s wrong

3. Check the Discharge Line

Go outside and find where your discharge line exits the home.

• The outlet should be unobstructed by dirt, grass, or mulch
• Water should be directed at least six to ten feet from your foundation
• There should be no pooling or muddy areas along the line’s path that suggest a leak or improper drainage

4. Inspect the Check Valve

The check valve sits on the discharge pipe above the pump and prevents water from flowing back into the pit after the pump shuts off.

• If you hear water rushing back into the pit after the pump turns off, the check valve may be failing
• Look for any visible corrosion or wear on the valve itself

5. Listen to the Pump Run

After your bucket test, pay attention to how the pump sounds during operation.

• Normal operation is relatively quiet and consistent
• Grinding, rattling, or a high-pitched whine can signal a worn impeller or motor issue
• Short cycling (turning on and off rapidly) often points to a check valve problem or a pit that’s too small for the volume of water coming in

6. Confirm Power and Backup Status

• Make sure the pump is plugged in to a dedicated outlet (not an extension cord)
• Check that the outlet is a GFCI type and that it hasn’t tripped
• If you have a battery backup unit, test it and verify the battery holds a charge

7. Check the Age of Your System

Sump pumps typically last seven to ten years with regular use. If yours is getting close to that range, particularly if you’ve had it through some heavy storm seasons, it may be worth thinking about a Greer sump pump replacement before it fails during a storm rather than after.

When to Call a Plumber

Some things on this list you can handle yourself. Others you shouldn’t. Call KT Plumbing if:

• Your float switch test shows the pump isn’t activating properly
• The pump runs but doesn’t seem to be moving water effectively
• You notice signs of corrosion, cracks in the discharge line, or unusual sounds
• Your system is approaching or past the ten-year mark
• You want a professional to assess whether your current plumbing installation in Greer is sized correctly for your home’s drainage needs

A pump that fails during a summer storm in Greer can mean hundreds or thousands of dollars in water damage. A maintenance check costs a fraction of that and usually takes less than an hour.

Schedule a Checkup Before Storm Season Peaks
