What To Do Before the Technician Arrives
While waiting for our technician, ensure your safety and prepare your home:
- Turn Off Power: Avoid electrical hazards by switching off the sump pump at its breaker.
- Move Valuables: Secure any items near the sump pump to prevent water damage.
- Test the GFCI Outlet: Verify it’s functioning properly to ensure the pump can operate.
- Perform a Bucket Test: Pour water into the sump pit to check if the float activates the pump.

Avoid entering any water if you suspect live electrical circuits are present. These preliminary steps can ensure a smooth repair process.

Upon arrival, our experts conduct a thorough diagnostic to pinpoint issues:
- Verify Power: Check the GFCI and dedicated circuit for proper operation.

- Check Valve Alignment: Prevent backflow with proper alignment.
- Measure Head Height & Flow Rate: Confirm the pump’s capacity to manage water effectively.
