Sump Pump Maintenance: Prepare Your Basement for Hurricane Season

As summer comes to an end, it brings changing weather and the potential for heavy rainfall. September is the climatological peak of Atlantic hurricane activity, making late summer an important time for seasonal maintenance. For both installers and homeowners, assessing sump pump performance before it is needed can be critical.

Regular sump pump maintenance can help identify potential problems before heavy rainfall puts your system to work. Whether you're preventing water in your basement, protecting a foundation from excess water or keeping clear water away from trenches, crawl spaces and tunneling projects, a seasonal inspection can help keep a sump pump system ready for changing conditions.

Sump Pump Maintenance Checklist

A sump pump may sit unused for extended periods, but significant rainfall can quickly increase the amount of water entering a sump pit. Without regular inspection, potential problems can go unnoticed until circumstances are critical. To prevent sump pump failure during the peak of hurricane season, late summer is an appropriate time to make sump pump maintenance part of a seasonal maintenance routine for contractors and homeowners alike.

Regular sump pump inspection can help identify conditions that may affect system operation. All inspection, testing and maintenance should follow the manufacturer's installation, operation and maintenance instructions for the specific equipment.

Test the Sump Pump

The first step in sump pump maintenance is confirming that the pump operates as intended.

For systems designed for automatic operation, the pump should start and stop appropriately as the water level changes. Unusual sounds, vibration or changes in normal operation may indicate a condition requiring further inspection.

Testing before a major storm can help identify potential issues before they contribute to sump pump failure.

Inspect the Sump Pit

The sump pit should be inspected for debris or other materials that could interfere with pump operation.

The pump and surrounding area should remain accessible for inspection and maintenance. Any buildup, obstruction or other issue should be addressed according to the manufacturer's recommendations.

Check the Discharge Line

The discharge line provides a path for collected water to leave the sump system.

Accessible portions of the discharge line should be inspected for visible damage, obstructions or other conditions that could interfere with water flow. The discharge location should also be appropriate for the installation, with water directed away from the building and foundation as intended.

An issue with the discharge system can affect overall sump pump performance even when the pump itself is operating normally.

Inspect the Float or Level-Sensing Device

Many sump pumps use a float switch or another level-sensing device to activate the pump as water rises.

The float or sensing mechanism should be able to operate freely without interference from the pump, sump pit or other objects. A restricted or improperly functioning level-sensing device can prevent the pump from responding as intended.

Check Accessible Connections and Controls

Accessible connections, controls and other system components should be inspected for visible signs of damage or wear as part of routine sump pump maintenance.

For homeowners, electrical issues or repairs requiring specialized knowledge should be handled by a qualified professional in accordance with applicable requirements and the manufacturer's recommendations.

Sump Pump Considerations for Contractors and Installers

For contractors and installers, late summer is an opportunity to review sump pump installations before seasonal rainfall increases the demands placed on residential water management systems.

Sump pump selection should account for the specific application and installation conditions. Factors such as the amount of water expected, the pumping requirements, the discharge configuration and the operating environment can all play a role in determining the appropriate pumping solution.

Installation is also an important part of overall system performance. Proper positioning of the pump, appropriate operation of level-sensing equipment and a suitable discharge arrangement can help support effective water removal.

Contractors can also use seasonal maintenance as an opportunity to educate homeowners about their sump pump systems. A brief review of how the pump operates, what signs may indicate a potential issue and when routine maintenance should be performed can help property owners better understand the role of the equipment in their overall water management system.

Late summer inspections are also a useful time to identify aging or damaged equipment and determine whether a system may require maintenance or replacement before the next major weather event.

Sump Pump Considerations for Homeowners 

A sump pump is not a solution for every type of basement leak. Water can enter through foundation cracks, windows, doors, plumbing issues or drainage problems. Persistent moisture, recurring leaks or signs of water intrusion should be evaluated to determine the source and the appropriate solution.

If the sump pump is making unusual noises, failing to activate, running continuously or showing other signs of a potential problem, a qualified professional should evaluate the system.

Professional assistance may also be appropriate when a basement continues to experience water intrusion despite a functioning sump pump, when foundation leaking is suspected or when a sump pump needs to be replaced or upgraded. Proper pump selection and installation can help ensure the system is suited to the home's specific water management needs.

Understanding the role of a sump pump and knowing when to seek professional help can help homeowners stay prepared before the next major rain event.

Make Sump Pump Maintenance Part of Fall Preparation

The worst time to identify a sump pump problem is during major rainfall. Hurricane season runs from June 1 through November 30, and while rainfall and storm activity vary by location, late summer provides a natural opportunity to inspect equipment that may be called on during periods of heavy precipitation.

Sump pumps can be easy to overlook when operating normally, but routine inspection and maintenance are important parts of seasonal water management. A late summer sump pump check should include testing the pump, inspecting the sump pit, checking the discharge line, verifying the level-sensing device and looking over accessible connections and controls.

For both installers and homeowners, making sump pump maintenance part of a pre-fall routine provides an opportunity to identify potential problems before they contribute to sump pump failure when the system is needed most.
