What to Do After a Basement Flood: How to Check Your Sump Pump

A flooded basement is stressful. After the water is gone, you may think the problem is over. But your sump pump could have been damaged during the storm. If it is not working the next time it rains, your basement could flood again. 

Taking a few simple steps now can help protect your home. 

Stay Safe First 

Before you go into your basement, make sure it is safe. 

Floodwater can have bacteria. It may also contain chemicals. Other harmful materials could be present too. It can also create electrical dangers. Stay away from water near outlets, appliances, or your electrical panel. Don’t walk through it. Only turn off the power if you can safely get to your main breaker. Avoid walking through standing water. 

Wear waterproof boots and gloves while cleaning up. If you smell natural gas, leave your home right away and call your gas utility. 

Take Pictures of the Damage 

Take pictures of damaged floors, walls, furniture, and personal belongings. If you file an insurance claim, these photos may help. Keep any receipts for cleanup or repairs. Your insurance company might ask for them. 

Remove the Water 

Standing water can cause more damage the longer it stays in your home. 

Use a wet vacuum or utility pump if the flooding is small. If your basement has a lot of water or sewage, contact a professional water restoration company. 

The sooner the water is removed, the better. 

Dry the Basement 

Even after the water is gone, your basement may still be wet. 

Use fans and a dehumidifier to help dry the area. If the weather is dry, open windows to improve airflow. 

Drying your basement keeps your home safe. It prevents wood rot and reduces moisture. 

Inspect Your Sump Pump 

Once your basement is dry, check your sump pump. 

Look for dirt, mud, gravel, or other debris inside the sump pit. Check the pump for rust, cracks, loose power cords, or other signs of damage. 

Also look at the check valve on the discharge pipe. This small valve keeps water from flowing back into the sump pit after the pump shuts off. 

If you see something off, schedule an inspection with Golden Rule. 

Test Your Sump Pump 

Testing your sump pump only takes a few minutes. 

Pour a bucket of water into the sump pit. The float should rise, and the pump should turn on by itself. It should pump the water outside and shut off when the pit is empty. 

If the pump does not start, check that it is plugged in and that the outlet or GFCI has not tripped. If it still does not work, have Golden Rule inspect the system. 

Check the Discharge Pipe 

Your sump pump cannot protect your home if water cannot leave the house. 

Check outside to see if the discharge pipe is clear. Look for mud, leaves, or other debris blocking it. Look for cracks, loose connections, or damage. 

The pipe should carry water several feet away from your home’s foundation. This stops water from flowing back into your basement. 

Check the Battery Backup 

If your home has a battery backup sump pump, test it after every flood. 

Make sure the battery is charged and the backup pump works properly. A battery backup keeps your sump pump running if the power goes out during a storm. 

If you are not sure how to test it, a Golden Rule technician can inspect the system for you. 

Know When It’s Time for a New Sump Pump 

Most sump pumps last about 7 to 10 years. 

Replace your sump pump if it:  

  • Makes loud noises  
  • Runs constantly  
  • Turns on and off too much  
  • Can’t keep up in heavy rain 

A Golden Rule technician can check your sump pump. They will help you decide whether to repair it or replace it. 

Schedule a Professional Inspection 

Some sump pump problems are hard to see. 

A Golden Rule technician can:  

  • Test the float switch  
  • Inspect the check valve  
  • Check the discharge pipe  
  • Ensure your sump pump works properly. 

A pro inspection after a basement flood can help. It can stop another costly flood.
