When to Repair vs. Replace Your Pool Equipment
Equipment · January 15, 2026 · 5 min read
That grinding noise from your pool pump has been getting louder for weeks. The pool heater takes 30 minutes longer to warm up than it used to. The filter pressure keeps climbing even after cleaning. The question every pool owner faces: do I spend $200 on a repair, or $1,500 on a replacement?
The answer depends on three factors: the age of the equipment, the cost of repair relative to replacement, and whether the underlying issue is a wearing part or a fundamental failure.
Pool Pumps: The 50% Rule
Pool pumps typically last 8–12 years. Our rule of thumb: if the repair costs more than 50% of a new pump and the pump is over 7 years old, replace it. You'll get a more efficient unit (especially if upgrading to variable speed) and avoid the next failure that's coming in 6–12 months.
Repair it:
Leaking shaft seal ($75–$150), capacitor replacement ($50–$100), O-ring replacements ($20–$50)
Replace it:
Burned motor windings ($400–$600 for motor alone), cracked volute/housing, bearing failure on a 10+ year pump
Technician Tip
When a motor bearing starts screaming, you've got about 2-4 weeks before full failure. Don't wait — a seized motor can trip your breaker, damage your timer, and even crack the pump housing. The repair cost triples.
Pool Filters: Lifespan by Type
Filters last longer than pumps, but the media inside doesn't last forever. Cartridge filters need new cartridges every 1–3 years ($50–$200). Sand filters need new sand every 5–7 years ($200–$400). DE filters need new grids every 5–8 years ($300–$500). The filter housing itself can last 15–20 years.
If your filter pressure stays above 25 PSI even after cleaning, or you're cleaning it every few days instead of monthly, it's time for new media — not necessarily a new filter.
Pool Heaters: The Most Expensive Gamble
Gas heaters last 7–10 years. Heat pumps last 10–15 years. Heaters are the most expensive pool equipment to replace ($2,500–$5,000 installed), so the repair-vs-replace math matters the most here.
Common heater repairs like igniter replacement ($150–$250) or thermostat replacement ($200–$350) are almost always worth doing. But if you're looking at a cracked heat exchanger ($800–$1,200 for the part alone), that's replacement territory — especially on a unit over 8 years old.

Schedule Equipment Diagnosis →The Bottom Line
Don't throw money at equipment that's at end of life. And don't replace equipment that just needs a $100 part. The best move is having a RAIL-licensed technician diagnose the issue before you decide — a 15-minute inspection can save you thousands in either direction.
