Using A Sump Pump To Prevent Basement Water Damage

sump pumpion, forcing water upward into the basement. A common source of episodic basement flooding is water intrusion through basement walls during heavy rains. Pooling ground water saturates the soil surrounding the foundation, exerting hydrostatic pressure on basement walls and triggering leaks through cracks and gaps.

A sump pump installed in the basement floor is a must to prevent water damage, as well as secondary consequences like toxic mold growth. As water seeping from beneath the foundation or leaking through walls collects inside the basin, the unit automatically actuates and pumps it outside to a discharge point, usually behind the house.

Here are three suggestions to ensure your sump pump safeguards against basement water damage

  • Don’t rely on AC power alone. Severe weather that causes basement flooding often triggers utility power outages, too. Install a sump pump that incorporates a DC battery backup feature to ensure the unit actuates when it’s needed most, even if the grid goes down.
  • Test the system twice a year. In some locales, the pump may not actuate for months at a time. If a malfunction develops while it’s idle, you may be unaware that the system no longer functions properly—until it’s too late. Make sure the basin is free of foreign objects that could clog the pump. Then pour five gallons of water into the basin and observe to verify that the pump automatically turns on, fully empties the basin, then turns off.
  • Check the discharge pipe. Verify that the outdoor span of pipe slants slightly downward and discharges far from the house to prevent water from re-entering the basement. If the discharge pipe doesn’t fully drain, water inside will freeze in cold weather and the pump will not be able to empty the basin.
