Preparing Sump Pumps For Spring
As the winter snow begins to melt and spring showers approach, your sump pump becomes the most important appliance in your home for preventing basement flooding
Follow these steps to prepare your sump pump for the spring thaw.
1. Clear Debris from the Pit
Begin with a visual inspection of the sump basin.
Remove the Cover: Take off the lid and check for any mud, gravel, or small stones that may have accumulated.
Clean the Pump: If possible, lift the pump out and clean the inlet screen or grate on the bottom. Debris here can cause the motor to overwork and eventually burn out.
Check the Float: Ensure the float arm can move freely up and down without being obstructed by the pit walls or debris.
2. Inspect the Power Source
A sump pump is useless without reliable power.
Verify the Connection: Check that the pump is plugged into a Ground Fault Circuit Interrupter (GFCI) outlet.
Examine the Cord: Look for any signs of corrosion or damage to the power cord.
Reset if Necessary: If the pump seems unresponsive, try "rebooting" it by unplugging it for 30 seconds before plugging it back in.
3. Test the Pump’s Operation
Testing is the most critical step in spring preparation.
The Bucket Test: Slowly pour about 5 to 10 gallons of water into the pit.
Watch for Activation: The pump should automatically turn on as the float rises.
Listen for Issues: Listen for unusual grinding, thumping, or excessive vibration, which could indicate worn-out parts.
Check the Check Valve: Ensure the check valve is working correctly to prevent water from flowing back into the pit once the pump shuts off.
4. Clear the Exterior Discharge Line
If the water has nowhere to go, it will simply cycle back into your basement.
Check for Blockages: Inspect the pipe where it exits your home. Ensure it isn't blocked by leftover ice, snow, mulch, or even rodent nests.
Confirm Proper Drainage: The discharge pipe should direct water at least 10 to 20 feet away from your foundation to prevent it from seeping back into the ground near your walls.
5. Verify Your Backup System
Spring storms often come with power outages.
Test the Battery: If you have a battery backup, unplug the main pump and perform the bucket test again to ensure the backup system takes over.
Install an Alarm: Consider a Sump Pump Alarm that provides an audible notification if the water level rises too high or the pump fails.
