Pool Equipment Repair Guide: Pumps, Filters & Heaters

Pool equipment failures are common — but catching them early saves money. Here are the most common issues, repair costs, and when to call a professional.

Pool Pump Problems

The pump is the heart of your pool system. Common issues:

Noisy pump: Usually worn bearings — motor replacement costs $150–$400
Pump not priming: Air leak in suction lines — $75–$200 to fix
Low flow: Clogged impeller or basket — often $75–$150 to clean
Pump won't start: Capacitor or motor failure — $100–$300

Pump lifespan: 8–12 years. Replacement cost: $300–$800 installed.

Filter Problems

Pool filters come in three types: sand, DE (diatomaceous earth), and cartridge. Common issues:

High pressure (sand/DE filter): Needs backwashing — DIY task
Cloudy water after backwash: Media needs replacement — $100–$300
Torn DE grids: Replacement cost $150–$400
Damaged cartridge filter: $50–$200 for new cartridge

Pool Heater Problems

Heater won't ignite: Dirty heat exchanger or igniter — $100–$300
Insufficient heating: Scale buildup or low flow — $150–$400
Error codes: Vary by brand; often $75–$200 diagnostic + repair

Heater lifespan: 7–15 years. Replacement: $1,500–$4,000 installed.

Repair vs. Replace: The Rule of Thumb

If a repair costs more than 50% of the replacement cost, and the equipment is more than half its expected lifespan, replacement usually makes more financial sense.

Variable Speed Pump Upgrade

If your pump is due for replacement, consider upgrading to a variable speed pump. They use 30–70% less energy than single-speed pumps and often pay for themselves in 2–3 years through energy savings. Cost: $600–$1,200 installed.

Bottom line: Regular equipment inspections during service visits catch problems early. Find licensed pool repair companies near you at poolservicemap.com.
