Sump Pump Failure Cleanup in Arvada, CO

Why sump pumps fail in Arvada

Sump pits are common in homes near Ralston Creek, Van Bibber Creek and Leyden Creek, and in newer west-side subdivisions where perimeter drains feed a pit. They work hardest during the wettest weeks of the year, which is exactly when they fail:

• Power goes out during a spring snowstorm or a summer thunderstorm, and there is no battery backup
• The float switch sticks against the side of the pit
• The pump is undersized for heavy snowmelt and runs behind
• The discharge line freezes or clogs, so water cycles back into the pit

Cleanup that goes beyond the puddle

Water from a pit spreads along the lowest part of the slab, usually under the carpet and into the nearest wall. The mitigation team maps it with meters, extracts the carpet and pad, and opens the drywall only where readings show it is wet. On a finished lower level, that is often a strip along the bottom of one or two walls.

If the pump failed because the basement is taking more groundwater than it can handle, the same drying process applies as for basement flooding. For spring thaw losses, see snowmelt and runoff flooding.

Preventing the next overflow

A battery backup pump, a high-water alarm and a check of the float each fall are the usual fixes. The Ready.gov flood page covers power-loss safety around water, and Colorado State University Extension publishes homeowner material on Colorado soils and drainage.
