Common Sump Pump Repair Scenarios
Sump Pump Not Running
When rain is coming and your sump pump won't activate, your basement is at risk. Check the float switch and power supply first.
Sump Pump Running Constantly
A pump that runs non-stop may have a stuck float switch, undersized pump, or high water table issue that needs professional diagnosis.
Sump Pump Replacement
Sump pumps last 7-10 years. Replace proactively before failure to avoid flood damage during the next heavy rain.
Battery Backup Installation
A battery backup sump pump activates during power outages — the exact time you're most likely to need it.
