Understanding Sump Pump Sizing
Proper pump sizing is crucial for effective water removal and basement protection.
- Flow Rate Requirements Based on drainage area and rainfall intensity.
- Head Pressure Vertical lift plus friction losses.
- Soil Conditions Affects water infiltration rate.
- System Capacity Includes safety factors for peak loads.
Design Considerations
Safety Factor
Add 20% capacity for unexpected loads.
Backup Systems
Consider battery backup for critical applications.
Pit Design
Size pit for proper pump cycling.
Maintenance Access
Allow space for servicing.
