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

  1. Enter pump rated GPM.
  2. Enter equipment $/GPM.
  3. Enter pump room mod cost.
  4. Enter electrical + controls.
  5. Enter testing + commissioning.
  6. Enter contingency %.
  7. 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.
