Need to replace your well pump? Whether your pump has failed completely or is showing signs of decline, understanding the replacement process helps you make informed decisions and avoid surprises.

When to Replace Your Well Pump

• Complete failure: Pump won't run at all despite power
• Age: Pump is 12-15+ years old and having issues
• Declining performance: Gradual loss of pressure or flow
• Frequent repairs: Multiple repairs in recent years
• Excessive power use: Electric bills climbing without explanation
• Changed needs: Current pump can't meet water demand

The Replacement Process

1. Assessment: Verify pump failure and assess well condition
2. Pump selection: Choose appropriate pump for your well depth and water needs
3. Pull old pump: Remove existing pump assembly from well
4. Inspect components: Check drop pipe, wiring, check valve
5. Install new pump: Lower new pump to proper depth
6. Connect and test: Wire connections, pressure settings, system test

What Affects Replacement Cost?

• Well depth: Deeper wells require more labor and materials
• Pump horsepower: Larger pumps cost more
• Pump brand: Premium brands (Grundfos, Franklin) vs. economy
• Drop pipe condition: May need replacement
• Wiring condition: Old wire may need replacement
• Well access: Difficult access increases labor time

Choosing the Right Pump

Pump selection depends on:

• Well depth: Determines pump type and size
• Water level: How deep the pump needs to sit
• Required flow (GPM): Based on household size and usage
• Pressure requirements: Distance to house, elevation changes

We recommend the right pump for your specific well and needs—not oversized, not undersized.
