If a Westminster sump pump is losing ground, start by cutting power safely and checking the float, then look at the discharge line outside. Most failures trace to a stuck switch, a bad check valve, a tripped circuit or a worn motor. Call the number on this page to be connected with a local plumber in Westminster.
Westminster at a glance
Westminster's homes run from older neighborhoods to newer development, and Census survey figures put the median build year at 1987, with about 34% of homes built before 1980. The City of Westminster runs about 411 miles of sanitary sewer, treated at its Big Dry Creek facility or by Metro Water Recovery, and property owners maintain the lateral from the house to the city main. A sump line plumbed into that lateral sends groundwater where it does not belong, so the discharge should end outdoors. Winter adds another wrinkle: on a cold Front Range night, a discharge pipe that holds water can freeze and leave the pump pushing against a plug of ice.
What to do right now
- Kill the power safely. If water is near the outlet, shut off the breaker before stepping close.
- Check the float. Make sure it is not wedged against the basin wall or tangled in the cord.
- Look outside. Find where the discharge pipe ends and clear any ice, snow or debris blocking it.
- Listen after a cycle. A rush of water back into the pit points to a failed check valve.
- Move valuables. Lift boxes and electronics off the basement floor.
- Call if it still will not run. A plumber can test the motor and switch.
Symptom and likely cause
| Symptom | Likely cause |
|---|---|
| Pump silent with water in the pit | Stuck float, failed switch or no power |
| Hums but moves no water | Jammed impeller or seized motor |
| Runs in short bursts | Float set too tight or check valve leaking back |
| Runs constantly in dry weather | Water falling back down the pipe, or a nearby supply leak |
| Water at the foundation outside | Discharge ends too close to the house |
What affects the cost
- Part repair versus full replacement
- Pump size and type
- Extending or rerouting the discharge
- Battery backup or alarm add-ons
- Whether a water-powered backup triggers backflow requirements
- Freeze protection for an outdoor line that crosses a long, flat yard
On that last point, Westminster's cross-connection program assesses single-family homes by site hazard and requires assemblies to be tested when installed and every year after. Plumbing modifications need a permit from the City of Westminster Building Division, and the plumber can confirm whether yours does.
