7 Mistakes You’re Making with Sump Pump Maintenance in Montgomery County (And How to Fix Them Today)

If you’ve lived in Montgomery County for any length of time, you know how unpredictable our weather can be. One minute it’s a beautiful afternoon in Norristown, and the next, a heavy SEPA downpour is drenching your backyard. In those moments, there is one unsung hero standing between you and a very expensive swimming pool in your basement: your sump pump.

But here’s the stressful truth: most homeowners don't think about their sump pump until they hear the sound of splashing water where it shouldn’t be. By then, you’re looking at an emergency flood cleanup scenario that could have been totally avoided.

At My Water Damage Hero, we see the aftermath of sump pump failures every single day. From mold remediation needs in Pottstown to major water damage restoration in Lansdale, a little maintenance goes a long way.

Are you making these seven common mistakes? Let’s find out: and more importantly, let’s fix them before the next storm hits.

1. The "Out of Sight, Out of Mind" Unplugging

It sounds silly, right? Why would anyone unplug the one thing keeping their basement dry? You’d be surprised. We often see homeowners unplug the pump to use the outlet for a power tool, a festive light display, or even a spare freezer, and then simply forget to plug it back in.

The Fix: Go downstairs right now and check. Is it plugged in? Is the cord in good shape? If you find yourself constantly needing that outlet, it’s worth hiring an electrician to add a dedicated circuit. Never leave your home’s safety to memory.

2. Ignoring the Discharge Pipe

Your sump pump’s job is to move water out of the pit. But where does that water go? If your discharge pipe is clogged with leaves, frozen solid during a cold snap, or: worst of all: dumping water right next to your foundation, you’re in trouble.

When water is discharged too close to the house, it just seeps back down through the soil and into your sump pit again. This makes your pump work twice as hard for no reason.

The Fix: Ensure your discharge pipe extends at least 10 feet away from your foundation. Check the exit point for debris, nests, or rocks.

3. Letting the Pit Become a Trash Can

Over time, dirt, gravel, and even small toys can find their way into your sump pit. If these items get sucked into the pump, they can clog the intake screen or damage the internal impeller. A jammed pump is a dead pump, and a dead pump leads to a basement full of water.

The Fix: Every few months, take a peek inside the basin. If you see silt or debris, scoop it out. A great trick is to place your pump on a few flat bricks at the bottom of the pit. This keeps it slightly elevated so it isn't sucking up the heavy sediment that settles at the very bottom. This simple step can prevent a massive sewage cleanup or flood mess later.

4. The Stuck Float Switch

The float switch is the "brain" of your sump pump. As the water rises, the float lifts; once it reaches a certain height, it tells the pump to turn on.

We often see pumps that have shifted inside the basin, causing the float switch to get pinned against the wall. If the float can’t rise, the pump won’t start. If it gets stuck in the "up" position, the pump will run continuously until the motor burns out.

The Fix: Gently reach into the pit and ensure the pump is centered. Manually lift the float switch to see if it moves freely and triggers the pump. It should feel smooth, not crunchy or stuck. This is a vital part of the simple 3-minute basement check we recommend for all Montgomery County residents.

5. Forgetting the Check Valve

The check valve is a small device on the discharge pipe that prevents water from flowing backward into the pit once the pump shuts off. If this valve fails, the water that was just pumped out will rush back down, filling the pit and causing the pump to cycle on and off repeatedly. This "short-cycling" wears out the motor fast.

The Fix: Listen to your pump. If you hear a loud "thump" when it shuts off, or if you notice the water level in the pit rising immediately after the pump stops, your check valve might be shot. Replacing a check valve is a cheap DIY fix that can save you thousands in water damage restoration costs.

6. Relying on a Single Power Source

Montgomery County is beautiful, but our storms can knock out power in a heartbeat. If the power goes out, your sump pump goes out. And usually, the power goes out right when it’s raining the hardest.

The Fix: Invest in a battery backup system. This is a second, battery-powered pump that sits in the pit with your main pump. If the power fails or the primary pump can't keep up, the backup kicks in. It’s the best insurance policy you can buy for your basement. Without it, you’re one lightning strike away from needing emergency flood cleanup in SEPA.

7. Neglecting the "Bucket Test"

The biggest mistake you can make is assuming the pump works just because it’s there. You don't want to find out it's broken during a hurricane.

The Fix: Perform a "Bucket Test" at least twice a year. Slowly pour a five-gallon bucket of water into the sump pit. Watch the float rise and make sure the pump kicks on and clears the water quickly. It’s a 60-second task that provides total peace of mind.

If you notice a musty smell during this test, it could be a sign of early mold growth in the basin. For more on that, check out our post on hidden mold after water damage.
