Sump Pumps

A pump that works when the storm hits, not after.

A sump pump sits in a pit at the lowest point of a crawl space, basement or low yard area and pumps collected water out and away before it causes damage. It only runs during heavy rain, which is exactly why failures go unnoticed until the crawl space floods. AccuFlow handles sump pump installation in Lodi, Acampo and nearby towns, replacement of worn or undersized pumps, and sump pump repair for stuck float switches, failed check valves and clogged discharge lines.

New Pits & Pumps

Sump pits and pumps installed at the low point, sized to the water you get.

Pump Repair

Stuck float switches, failed check valves and clogged discharge lines fixed.

Battery Backups

Backup pumps that keep running when a storm knocks out the power.

Discharge Routing

Water carried far enough from the foundation that it doesn’t come right back.

Why sump pumps fail

The most common failures are a float switch that sticks, a pump that burns out after years of sitting idle, a check valve that lets water run back into the pit, and a discharge line that is clogged, frozen or dumps water right next to the house. Most pumps last around 7 to 10 years. Testing the pump before the rainy season, by pouring water into the pit and watching it start and stop, catches most problems before they matter.

Signs your sump pump needs attention

  • The pump runs constantly or cycles on and off
  • The pump hums but no water moves
  • Standing water in the pit or crawl space
  • The pump is more than 7 to 10 years old
  • Rust or a bad odor at the pit
  • Water discharging right next to the foundation

Battery backup pumps

The heaviest storms are also the ones most likely to knock out power, which is when a standard pump stops working. A battery backup sump pump sits alongside the main pump and takes over automatically. For homes near the Delta and river areas with a high water table, it is cheap insurance against a flooded crawl space.

Water in the yard, not under the house?

Surface water pooling around the foundation or in side yards is a drainage problem rather than a sump problem. See French drains and catch basins for moving that water away from the house.

What affects the cost of a sump pump

  • New pit or replacement: digging a new pit is more work than swapping a pump.
  • Pump size and type: capacity and submersible versus pedestal models.
  • Battery backup: adding a second pump and battery.
  • Discharge line: how far the water has to be carried from the house.
  • Access: tight crawl spaces take longer to work in.

Common Questions

Sump Pump FAQs.

Quick answers before you call.

Typically 7 to 10 years. Pumps that run often, or sit idle for long stretches, can fail sooner.
If a flooded crawl space or basement would cause real damage, yes. Storms that bring heavy rain often knock out power too.
Far enough from the foundation, and downhill, that the water can’t flow back toward the house. It should never discharge into the sewer.
Pour a bucket of water into the pit. The float should lift, the pump should start, empty the pit and shut off.
A stuck float switch, a failed check valve letting water flow back, or a high water table. We diagnose which one.
Yes. Most valley homes with water problems have crawl spaces rather than basements, and that is where most of our sump pumps go.
