When to test
- Before spring melt in March
- Before summer storm season
- After a long dry spell
- After any power outage or electrical work
How to test
- Confirm the pump cord is in and the outlet has power.
- Pour water in slowly until the float lifts.
- The motor should start, lower the water and switch off on its own.
- Step outside to see water leaving the discharge outlet.
What to look for
Listen for grinding or rattling. Watch for the float catching on the side of the pit. Check the check valve does not let water flow back. Look for rust or a cracked housing.
Battery backups
If you have a backup pump, unplug the main pump and test the backup the same way. Check the battery date and the charger light.
If your pump is over seven years old and runs often, consider replacing it before it fails.
Record each test with the date on a piece of tape on the discharge pipe. A record helps you notice when the pump starts slowing down year to year.
