Pool Equipment Lifespan Cheat Sheet

Realistic lifespans

These are field-observed numbers from over 27,000 service visits across DFW.

• Single-speed pump: 7–10 years
• Variable-speed pump: 10–15 years
• Cartridge filter housing: 12–20 years; cartridges 1–2 years
• Sand filter housing: 20+ years; sand 5–7 years
• DE filter grids: 5–8 years
• Gas pool heater: 7–10 years
• Heat pump: 10–15 years
• Salt cell: 5–7 years (with proper cleaning, up to 9)
• Pool light (LED): 15+ years
• Pool light (incandescent): 3–5 years
• Automation control panel: 12–18 years

What shortens equipment life

Most equipment dies young because of preventable chemistry mistakes:

• Calcium hardness above 450 ppm scales heater elements and salt cells
• Low pH (under 7.0) eats pump impellers and heater heat exchangers
• Cyanuric acid above 100 ppm reduces chlorine effectiveness, causing constant shocking
• Skipping winterization invites freeze damage
• Running single-speed pump at full RPM 24/7 burns out bearings

When to replace vs repair

Replace if any repair quote exceeds 50% of new-equipment cost, OR if the unit is past 80% of its expected life. Otherwise, repair makes economic sense.
