Yes. Check and test a sump pump at least once a year, and replace it once it is over 10 years old, runs constantly, makes unusual noises, or shows visible damage.

Why Sump Pump Maintenance Matters

A sump pump spends most of its life sitting idle in a pit, then has to start instantly and run hard during a storm. Silt, debris, a stuck float, or a clogged discharge line can keep it from doing that, and you usually find out at the worst possible moment. Annual maintenance is the only way to know it will work when water starts rising.

Annual Maintenance Checklist

  • Clean the pit and pump: Unplug the pump, remove debris and silt from the pit, and clear the intake screen so the impeller is not starved for water.
  • Test the float switch: Pour water into the pit until the float rises and the pump kicks on. Watch it drain the pit and shut off cleanly. A float that hangs on the side of the pit or sticks is a common failure point.
  • Inspect the discharge line: Check for kinks, cracks, or blockages, confirm the check valve holds so water does not drain back into the pit, and make sure the outlet outside is clear and carries water well away from the foundation.
  • Check power and backup: Confirm the pump is on a working outlet and the cord is intact. If you have a battery backup, test it and replace the battery on the manufacturer’s schedule.
  • Listen: Grinding, rattling, or a loud hum without pumping means bearings, the impeller, or the motor are wearing out.

If your area gets heavy rain or the pump cycles often, check it more than once a year.

Signs It Is Time to Replace the Pump

  • Age: A pump over 10 years old is living on borrowed time, even if it still runs.
  • Continuous operation: A pump that never shuts off may be undersized for the water volume, have a stuck float, or have a failed check valve that keeps refilling the pit.
  • Unusual noises or vibration: Mechanical wear that only gets worse.
  • Visible damage: Rust, a cracked housing, or corroded connections.
  • Frequent short cycling, slow draining, or tripped breakers: Signs of a failing motor or an electrical problem.

Sump Pumps in Central Texas

Most Austin and San Antonio homes are built on slabs without basements, so sump pumps here are usually found in homes with a basement or lower-level living space, below-grade garages and stairwells, crawlspaces, window wells, or lots that drain toward the house. Our rain tends to arrive in intense bursts that can overwhelm drainage quickly, and expansive clay soils shed water toward low spots instead of absorbing it, which puts more water at the foundation. A pump may sit unused for months and then be needed suddenly, so testing before storm season matters. During a hard freeze, an exposed discharge line can ice over, so insulate or check it when freezing weather is forecast.

What You Can Do vs. When to Call a Plumber

Homeowners can safely do the visual inspection, the pour-water test, debris cleanup, and clearing the outdoor outlet. Call a licensed plumber for anything electrical, a pump or check valve replacement, sizing a new pump for your pit and water volume, adding a battery backup or high-water alarm, or figuring out why water keeps showing up in the first place.
