Common Sump Pump Problems
- Pump Won’t Start
One of the scariest things is turning on your pump and… nothing happens. Causes usually include:
- A tripped circuit breaker
- GFCI outlets that have been triggered
- A malfunctioning float switch
Always start by checking your power connections. If it still doesn’t work, call a professional plumber to avoid making things worse.
- Strange Noises
Grinding, rattling, or screeching noises are your pump’s way of saying, “Help!” Usually, this points to:
- Debris stuck in the impeller
- A misaligned or worn motor
Ignoring these sounds can turn a small repair into a major expense. Cleaning or replacing the worn parts quickly keeps your pump running smoothly.
- Pump Cycles On and Off Too Often
A pump that keeps switching on and off is stressed. This wears it down faster. Causes can include:
- Float switch that’s out of calibration
- Improper pump settings
A licensed plumber can adjust or replace the float switch so the pump runs only when it should.
- Poor Water Pumping
If water isn’t being removed efficiently, the problem might be:
- Clogged or damaged discharge pipes
- A malfunctioning check valve
- Impeller issues
Left unchecked, this can quickly lead to basement flooding.
- Power Outages
Houston’s weather can cause short or long power outages. Since sump pumps run on electricity, even a few minutes without power can flood your basement. Battery backups or a generator are essential to stay protected.
- Overflowing Sump Pit
If water is spilling out of your sump pit, it means your pump can’t keep up. This can happen if:
- The float switch isn’t working properly
- The pump isn’t strong enough for the water volume
- The inlet screen is clogged
Regular inspections and sizing your pump correctly will prevent these overflow issues.
Step-by-Step Solutions for Sump Pump Repair
- Check the Power
Make sure the pump is plugged in, the breaker hasn’t tripped, and no GFCI outlets are triggered.
- Clean or Replace the Impeller
Debris can block the impeller, reducing water flow. Remove the buildup and inspect for damage. If it’s broken, a professional plumber can replace it.
- Adjust the Float Switch
The float switch triggers the pump when water rises. If it’s off, the pump cycles too much or doesn’t start. Adjust according to manufacturer instructions—or let a plumber handle it safely.
- Inspect the Check Valve
A faulty check valve lets water flow backward, making the pump work harder. Replacing it restores efficiency.
- Test Battery Backup
Check the battery regularly. Replace it if needed to ensure your pump works during outages.
- Electrical Issues
If the pump keeps tripping the breaker, call an electrician to inspect the wiring and prevent damage.
- Clear Discharge Pipes
Blocked or damaged pipes reduce water flow. Clear debris or replace broken sections for proper drainage.
- Maintain the Sump Pit
Debris in the pit can obstruct the float switch or water flow. Clean it regularly. A professional plumber can check for structural issues as well.
When to Replace Your Sump Pump
Sometimes repairs aren’t enough. You should consider replacement if:
- Your pump is 10+ years old: Older pumps need constant repair.
- You have recurring problems: Constant repairs indicate it’s near the end of its life.
- It’s undersized: A smaller pump may not handle Houston’s heavy rain.
- There’s rust or corrosion: Extensive wear can’t always be repaired.
- It lacks modern features: Newer pumps offer battery backups, alarms, and remote monitoring.
Replacement is often a more reliable and cost-effective choice in the long run.

| Features | Existing system only | Backup, alarms, energy efficiency |
If you’re facing frequent issues or an outdated pump, replacement is often the smarter move.
