Commerce City sump pump problems usually trace to a float that sticks, a check valve that lets water fall back, a power issue or a motor that has run its course. A plumber can tell you whether a repair will hold, and make sure the discharge stays out of the South Adams County Water and Sanitation District sewer. Call the number on this page to be connected with a local plumber in Commerce City.

Commerce City water, sewer and your sump
South Adams County Water and Sanitation District (SACWSD) provides water and sewer to the Commerce City area. It treats wastewater at its own Williams Monaco plant in Henderson rather than sending it to Metro Water Recovery, and it draws a clear line between its public sewer and the private sewer lines property owners own. Pumped groundwater does not belong in either one, so a sump hose run into a laundry sink, floor drain or cleanout should be rerouted to the yard. If a drain backs up, SACWSD asks customers to call 303-288-2646 so it can help sort out whether the problem is in the public main or your private line.
For backups that run on water pressure, SACWSD's backflow program centers on commercial users, but it also says residential facilities must protect the drinking water supply under the plumbing code. A water-powered sump backup needs that protection.
Repair, replace or add a backup
| Situation | Usual direction | Commerce City note |
|---|---|---|
| Float sticks or check valve leaks | Repair the part | Sensible if the motor still runs strong |
| Motor overheats or hums without pumping | Replace the pump | Typical once a pump has run for years |
| Power outages during storms | Battery backup | No connection to SACWSD water needed |
| Want no battery to maintain | Water-powered backup | Requires backflow protection on the supply line |
| Pump cannot keep up | Check the setup before upsizing | Gutters, grading and pipe size often matter more |
Warning signs
- A full pit and a silent pump
- Long run times with little water leaving
- Rapid cycling
- Water rushing back into the basin after it stops
- A wet floor or musty basement smell
Timing it right
The best time to test a pump is a dry week before spring snowmelt and summer storms, not during a downpour when plumbers are busiest. Pour water into the pit and watch it run. If you replace the pump or change piping, the City of Commerce City Building Safety Division at 303-289-3790 can confirm whether a permit is needed, and the plumber can handle it through the city's eTRAKiT portal.
