A Louisville sump pump that stops clearing the pit usually has a float that will not lift, a check valve that leaks, a power issue or a worn motor. A plumber can test each part and make sure the discharge leaves the property instead of reaching the city sewer. Call the number on this page to be connected with a local plumber in Louisville.
How the visit usually goes
The call connects you with an independent plumber who works in Louisville. Be ready to say whether water is coming up now, where the pit is and what the pump does when it should run. On site, the plumber checks the power supply, raises the float to see whether the motor starts, watches the pit drain and checks that the check valve holds. Then they follow the discharge line outside to see where the water goes. From there you can decide between fixing a part, replacing the pump and adding a backup.
Cost factors
- Part repair versus a new pump
- Pump capacity for how quickly the basin fills
- Pit condition, such as silt, a missing lid or a cracked liner
- Extending the discharge away from the foundation
- Battery backup and alarm options
- Inspection if the job changes plumbing
What is different in Louisville
Louisville is a former coal-mining town in southeastern Boulder County with a historic downtown, and hundreds of homes were rebuilt after the December 2021 Marshall Fire. That gives the city an unusual mix: century-old houses near Main Street, homes from later decades and many newly built basements. A rebuilt home has a newer pit, but a new pump still needs testing, and the discharge route a builder chose is worth checking.
The City of Louisville runs water and sewer, and its wastewater treatment plant on the east side of town discharges to Coal Creek. That system is for household wastewater, so a sump line into a floor drain or laundry sink should be rerouted outside. For sewer backups, Public Works Operations answers at (303) 335-4750 on weekdays from 7 AM to 3:30 PM, and the on-call line is (303) 489-2301 after that.
Few homes are on wells, so a water-powered backup would run on city pressure. Louisville's cross-connection program runs through Backflow Solutions, Inc., so ask the plumber what testing a backup would involve. The Building Safety Division handles plumbing inspections when work needs a permit.
Quick prep list
- Flip the pump's breaker if water is near the cord
- Make the basement and pit easy to reach
- Know where the discharge pipe comes out
- Have the pump's label or paperwork handy
