How To Pump Water Out Of Your Basement 

Dealing with a flooded basement can be a homeowner’s nightmare. Whether caused by natural disasters, plumbing issues, or sewer backups, it’s a serious issue that requires immediate attention. This guide will walk you through the process of safely and effectively pumping water from your basement, from initial safety precautions to prevention strategies.

Basement Flooding Causes

Before tackling water removal, it’s important to understand why your basement might flood. This can help you prevent future incidents and address the root cause of the problem. Three common causes of basement floods include:

• Natural disasters and heavy rainfall: Severe weather events and excessive rainfall can overwhelm your home’s drainage system, leading to water accumulation in your basement. In extreme cases, nearby rivers or streams may overflow, redirecting water into your home. 
• Plumbing issues and pipe bursts: Old or damaged water pipes can suddenly give way, releasing large amounts of water into your basement. Regular maintenance and prompt repairs can help prevent these unexpected plumbing emergencies.
• Sewer backups and septic system failures: A flooded septic system or sewer line backup can cause contaminated water to enter your basement. This type of flooding is particularly hazardous and requires professional handling due to the potential health risks involved. 

Safety First: Precautions Before Pumping Water From Your Basement

Before you begin removing water from your basement, take proper safety measures to protect yourself and your home.

Turn Off the Electricity

Water and electricity are a dangerous combination. Before entering a flooded basement, make sure that the power is turned off at the source. If your circuit breaker panel is on the first floor, you can cut power to the basement while maintaining electricity upstairs for pumping equipment. However, if the panel is in the basement, contact your power company to shut off electricity to the entire house. For added safety, use a portable generator to power necessary equipment—placing it well away from the home to avoid carbon monoxide poisoning.

Identify the Water Source

Locate the source of the flooding and determine if it has stopped. If the surrounding area is flooded, you may need to wait for water levels to recede before starting the removal process. Identifying whether the source is internal or external can greatly influence your next steps.

Assess Structural Damage

In cases of extreme flooding, be cautious about removing water too quickly. The Federal Emergency Management Agency (FEMA) warns that the weight of saturated soil can put pressure on basement walls and floors, potentially causing them to buckle or collapse. In major floods, it may be safer to allow some water to remain in the basement temporarily to equalize pressure. Consulting a structural engineer can provide a thorough assessment and guidance.

Types of Pumps for Basement Water Removal

Choosing the right pump is essential for efficient water removal. Here are some common types of pumps used for basement flooding:

Submersible Pumps

Submersible pumps are designed to be fully submerged in water. They’re efficient for removing large volumes of water quickly. These pumps come in various sizes and capacities, with some models capable of pumping up to 4,000 gallons per hour. Homeowners may want to consider buying or renting a portable submersible pump. They also typically feature robust motors that can handle continuous operation.

Sump Pumps

Some basements are already equipped with sump pumps, which are installed in a pit at the lowest point of the basement. These automatically activate when water levels rise, making them ideal for ongoing water management. Regular maintenance and testing of your sump pump system can help it operate efficiently during an emergency.

Battery-powered sump pumps and gasoline-powered pumps can operate even if the electricity is out.

Utility Pumps

Utility pumps are versatile and can be used for various water removal tasks. They’re often portable and can handle both clean and dirty water, making them suitable for basement flood cleanup. They can also be used for tasks such as draining hot tubs, pools, or ponds.

How To Pump Water Out of Your Basement

Follow these three steps to effectively remove water from your basement:

1. Set Up Your Pump

Place your pump at the lowest point of the flooded area. If using a submersible pump, ensure it’s fully submerged. For non-submersible pumps, position them on a sturdy, level surface above the water line. This will help to prevent clogging.

2. Proper Hose Placement

Attach a hose to the pump’s discharge port. Direct the hose away from your home’s foundation, ideally towards a storm drain or an area where the water won’t flow back into your basement. Make sure it’s free of obstructions to maintain a steady flow of water.

3. Monitor Water Levels

Start the pump and monitor its progress. In cases of severe flooding, FEMA recommends first marking the water line and then pumping 1 foot of water. After waiting 24 hours, if the water level hasn’t changed, pump another foot of water out of the basement and mark the new level. Wait another 24 hours, and if the water level hasn’t gone up during the past 48 hours, you can draw out 2 to 3 feet of water every 24 hours until it’s removed completely from your basement.

This gradual approach helps prevent structural damage to your foundation.

Sump Pump Alternatives

If you don’t have access to a pump or are dealing with smaller amounts of water, consider these alternative methods:

• Bucket brigade: If your area is without electricity or pumps aren’t available, bucket brigades with friends and family can be effective, although labor-intensive. Form an assembly line to speed up the process.
• Mop: For small amounts of water or final cleanup, use mops, towels, sponges, and squeegees to remove remaining moisture.
• Wet/dry vacuum: Wet/dry vacuums can handle both water and debris, making them ideal for cleanup after most of the water has been removed.

Dealing With Residual Moisture in Your Basement

After removing standing water, address residual moisture to prevent mold growth and further damage.

• Use fans and dehumidifiers: Set up fans to circulate air and use dehumidifiers to remove excess moisture from the air. This process can take several days, depending on the humidity levels and the extent of the flooding. Industrial-grade dehumidifiers can speed up the process, making it more efficient.
• Open windows for ventilation: If weather permits, open windows and doors to increase airflow. Cross-ventilation techniques, where air is allowed to flow freely between windows and doors, can be particularly effective.
• Remove wet materials: Discard any waterlogged items that can’t be properly sanitized, such as carpets, cardboard boxes, and damaged drywall or insulation. Use protective gear such as gloves and masks when handling contaminated materials.
• Use desiccants: Desiccants, such as silica gel or calcium chloride, can absorb moisture from hard-to-reach places. Place them in closed areas such as closets or small rooms where dehumidifiers might not be effective.

Professional vs. DIY Water Removal

While many homeowners can handle minor flooding, there are situations where professional help is necessary.

Know When To Call the Experts

Consider hiring professionals for extensive flooding, contaminated water (such as sewage backups), or if you suspect structural damage. Experts have specialized equipment and knowledge to handle complex situations safely and efficiently. Services include complete water extraction, disinfection, and drying of the affected area.

Cost Considerations for Professional Services

Professional water removal services can vary in cost depending on the extent of the damage and the services required. While it may seem expensive, professional help can prevent long-term damage and health hazards, potentially saving money in the long run. Always obtain multiple quotes and check for companies’ reviews and required permits.

Preventing Future Basement Flooding

Taking preventive measures can help protect your basement from future flooding incidents.

Install a Sump Pump System

A properly installed and maintained sump pump system can automatically remove water that enters your basement, providing ongoing protection against flooding. A battery backup system can keep the pump running during power outages.

Improve Exterior Drainage

Make sure your gutters and downspouts are clear and direct water away from your foundation. To further improve drainage, consider grading your yard to slope away from your home or installing French drains around your home.

Perform Regular Maintenance and Inspections

Regularly inspect your basement for signs of water intrusion, such as cracks in the walls or floor. Address any issues promptly to prevent small problems from becoming major flooding events. Annual maintenance of your plumbing system, sump pump, and exterior drainage will go a long way in keeping your home dry.

Install Water Alarms

Install water alarms and flood sensors in your basement. These devices alert you to leaks and minor flooding, allowing you to take action before the situation worsens.
