Fire Pump Replacement Cost Calculator
Fire pumps are life-safety equipment with code-driven testing + replacement schedules.
Total project cost
$207,760
Equipment cost
$67,500
Installation cost
$118,000
How the math works
Equipment = GPM × $/GPM. Total = (equipment + install) × (1 + contingency).
1,500 × $45 = $67.5k + $118k = $185.5k × 1.12 = $207.8k.
How to Use
- Enter pump rated GPM.
- Enter equipment $/GPM.
- Enter pump room mod cost.
- Enter electrical + controls.
- Enter testing + commissioning.
- Enter contingency %.
- Read total project cost.
Frequently Asked Questions
When to replace?
NFPA 25 mandates annual flow test, weekly run test. Replacement triggered by: 25-30 year service life (cast iron internals), failed annual test, controller obsolescence, capacity inadequate for new code or building expansion. Diesel pumps: 20-25 year life. Electric pumps: 25-35 year life. Modernization: variable speed drive retrofit common.
Cost ranges?
Equipment: $30-150 per GPM. 500 GPM electric: $30-75k. 1500 GPM: $60-150k. 2500 GPM: $100-250k. Diesel pumps: 30-50% premium over electric. Pump room modifications: $25-100k typical (concrete pad, piping changes, ventilation). Controllers (NFPA 20): $15-75k. Fire pump test header + meter: $10-30k.
Code requirements?
NFPA 20 governs fire pump installation. Listed equipment only (UL/FM). Dedicated electrical circuit + emergency power source (or diesel). Pump test header + flow meter for annual test. Backflow preventer at supply. Air vent + suction screen. Jockey pump for system pressure maintenance ($3-15k). Fire alarm monitoring of all critical functions.
Operational costs?
Annual NFPA 25 testing: $1,500-5,000 contracted. Quarterly inspection: $300-800/visit. Diesel fuel + maintenance: $2-8k/yr. Battery replacement (diesel): every 2-3 years $400-1,500. Electric motor maintenance: $500-2,000/yr. Contracted full-service maintenance plan: $3-15k/yr typical.
