Summer Storms Are Almost Over: Here's What To Check Before Fall

As the loud, fast summer storms fade, fall often brings longer, soaking rains—exactly the kind that exposes weak drainage and an unreliable sump pump. A quick round of sump pump maintenance now can help prevent basement leaks, musty odors, and expensive cleanup later. Use this short checklist before the next season change.

1) Test your sump pump

Don’t wait for a downpour to find out it failed. Pour water into the pit slowly until the float rises and the pump turns on. It should discharge water quickly, then shut off on its own. If it doesn’t start, trips the outlet, or runs constantly, it’s time to troubleshoot or replace it.

2) Check discharge lines

Follow the discharge pipe from the pump to the outside. Make sure it’s connected, not cracked, and not blocked by mud, leaves, or pests. Confirm the outlet sends water away from the foundation (generally several feet). If you use an exterior hose extension, check for kinks and remove buildup.

3) Verify battery backups

Fall storms can knock out power—when you need the pump most. If you have a battery backup, test it per the manufacturer instructions and confirm the alarm works. Check battery age, corrosion on terminals, and that the charger is functioning. If you don’t have a backup and your basement is finished or prone to seepage, consider adding one.

4) Look for signs of wear

During your sump pump maintenance check, inspect the power cord, plug, and float switch for damage. Listen for grinding, loud rattling, or a persistent hum (which can signal a jam or a failing motor). Also check the check valve (often on the discharge pipe): if water rushes back into the pit after shutdown, the valve may be stuck or failing.

5) Clean the pit

Unplug the pump before you work. Remove debris like gravel, silt, and sludge from the basin so it can’t clog the intake or jam the float. Wipe down the pit walls if there’s heavy buildup. If the pit smells foul, that can be a clue that stagnant water or organic debris is lingering.

6) Schedule an inspection

If your pump is older (many last around 7–10 years), cycles frequently, or fails any test above, schedule a professional inspection before fall rains ramp up. A plumber can verify sizing, check the discharge setup, test the backup system, and confirm your overall drainage plan is sound.

Final quick reminder

Pair sump pump maintenance with basic exterior drainage checks—clean gutters, extend downspouts, and make sure soil slopes away from the home. A small tune-up now can save you from a big wet surprise later.
