When heavy spring rainstorms sweep through the Upstate, the groundwater table rises rapidly. If you have a basement or crawlspace, your sump pump is the only line of defense preventing thousands of dollars in devastating flood damage. Because a sump pump sits dormant for months at a time, it is critical to test it before the storm hits.

1. Test the Float Switch

The float switch is a buoyant bulb attached to the pump. As water fills the pit, the float rises, eventually triggering the pump to turn on. Over time, debris can jam the float against the side of the pit. To test it, simply slowly pour a 5-gallon bucket of water into the sump pit until the float rises. Ensure the pump turns on, ejects the water quickly, and turns itself off.

2. Clean the Intake Screen

The bottom of the pump has a screen that prevents gravel and mud from entering the impeller. If this screen gets clogged with sludge, the pump will run but won't be able to suck up any water. Carefully pull the pump out and brush off any debris from the intake grate.

3. Install a Battery Backup

The most severe thunderstorms often cause power outages. If your home loses power, your primary electric sump pump is useless exactly when you need it most. We strongly urge every homeowner to install a battery backup system. These secondary pumps automatically kick in during a blackout, ensuring your basement stays dry even if the grid fails.

If your pump makes grinding noises, fails to activate, or is over 7 years old, it's time for a replacement. Contact Pipedex Plumbing & Drains at 864-900-0300 for expert sump pump testing and installation.
