Get the system pumping again
Many Port St. Lucie septic systems use a pump to move effluent from a pump chamber up to a mounded drainfield. When the pump, float switch, or control panel fails, the alarm sounds, and if ignored, wastewater backs up.
Common causes
- Worn-out effluent pump
- Stuck or failed float switch
- Tripped breaker or wiring issue
- Control panel or alarm failure
- Flooding from heavy rain overwhelming the system
What to do now
- Press the silence button on the alarm panel.
- Check the breaker for the pump.
- Minimize water use: no laundry, dishwasher, or long showers.
- Call for service. Most pump chambers have a limited reserve.
Typical repairs
Float replacement, pump replacement, panel repair, and wiring fixes. A good tech also checks why the pump failed (debris, electrical issues).
