Managing High Pressure from a Well Pump: Add Heads, Not Relief Lines

Use Excess Pressure by Adding Sprinklers, Not Wasting Water

50 PSI is fine for rotor heads. A 1.5 HP Flotec pump can deliver 18–24 GPM. With 2.5 GPM nozzles, run 7–9 heads per zone. Adding a pressure relief line back to the well wastes energy and water. Instead, design zones to use the pump’s full capacity efficiently.

Zone Design

• 7 heads per zone provides a safety margin for pump wear.
• Avoid zones with only 5–6 heads (causes pump overheating).
• Ensure pipe sizing (1" Sch 40) matches flow to minimize friction loss.
