A Frederick sump pump that stops working usually comes down to a float that will not move, a check valve that leaks back, a power problem or a tired motor. A plumber can locate the fault and confirm the discharge drains across the yard rather than into the St. Vrain Sanitation District sewer. Call the number on this page to be connected with a local plumber in Frederick.

Clues that something is wrong
- Snowmelt or a storm leaves the basin full while the motor sits idle
- You hear the pump, but the outdoor pipe produces nothing
- The pump starts and stops several times a minute
- A gurgle and splash back into the pit at the end of each cycle
- Carpet pad that feels wet, or a white mineral line on concrete walls
- A breaker that trips when the motor tries to start
Frederick conditions
Frederick began as a coal-mining town, McKissick, and is now a fast-growing family suburb in the Carbon Valley with Firestone and Dacono. Most basements here belong to newer homes, which means a builder-supplied pump in a builder-dug pit. Those pumps often run rarely, so a seized impeller or a float pinned by its own cord can go unnoticed until the first wet spring.
St. Vrain Sanitation District handles sewer for Frederick, and the district says the building sewer line belongs to the property, not to the district. Groundwater pumped into that line through a floor drain or laundry sink is the owner's problem twice over: it loads the district system and your own pipe. Keep the discharge outdoors. For sewer backups, the district staffs a 24-hour line at (303) 776-9570.
Water depends on where you live. The Town of Frederick serves residents east of I-25, Left Hand Water District serves those west of it, and Central Weld County Water District covers part of town. The town's cross-connection program requires assemblies to be tested at installation and every year by a certified tester. If a water-powered backup appeals to you, ask how that would apply on your supply before you buy one.
What moves the price
- Whether a single part or the whole pump has failed
- Upgrading a builder-grade pump to a sturdier model
- Extending a discharge that dumps right at the foundation
- Freeze protection for an outdoor run on an open, windy lot
- Battery backup or an alarm
After you dial
The number links you with an independent plumber who covers Frederick. Mention whether the pit is overflowing now and which side of I-25 you are on. If water is near an outlet, shut off the circuit first. The Town of Frederick Building Department handles permits, and its inspectors may verify the identity of the plumber on work that requires a license, so the plumber you reach can sort out what your job needs.
