What it is
Sump pump installation Sump pump installation is the process of setting a pump into a basement sump pit and connecting it to a discharge line so it automatically pumps groundwater away from the foundation before it can flood the basement.
Denver's spring snowmelt and heavy summer rains can push groundwater up around a foundation, and a working sump pump is often the only thing standing between that water and a flooded basement.
The pump is only as good as the pit and the discharge
Most sump failures are not the motor. They are a float jammed against the pit wall, a discharge line that freezes at the elbow, or a check valve that lets water fall right back in. A correct install fixes all three at the start.
- Properly sized pit with a sealed lid
- Cast iron or quality thermoplastic pump matched to inflow
- Check valve so water does not cycle back down
- Discharge that clears the foundation and does not freeze shut
You need a sump pump if
- Water shows up on the basement floor during heavy rain or melt
- There is an open pit with no pump in it
- The existing pump is over seven years old
- You are finishing the basement
- Efflorescence or a water line stain runs along the foundation wall

What a sump pump install includes
- Pit sizing and placement at the low point of the slab
- Pump selection matched to expected inflow, not just the cheapest unit
- Check valve and rigid discharge piping
- Sealed lid to control radon and humidity
- Discharge routed well away from the foundation with a freeze-resistant termination
- Optional battery backup or water-powered backup for outage protection
