Pool equipment — the pump, filter, heater, and any automation or sanitization systems — represents a significant investment that directly affects the pool’s operating cost, efficiency, and reliability. Understanding the condition and expected remaining life of each component, knowing when repair makes sense versus replacement, and asking the right questions about proposed repairs protects that investment and prevents expensive surprises.
“The repair-versus-replace conversation is the one I have most often with pool owners. The honest answer is almost always: it depends on the age of the equipment and the cost of the repair relative to the cost of replacement. A $400 repair on a 12-year-old pump makes sense only if you’re prepared to spend another $400 on the next repair in two years. A variable speed pump upgrade pays for itself in energy savings in 3–5 years and comes with a warranty. Age matters.”

Questions About Equipment Assessment
Will you assess the condition and age of all my pool equipment?
Ask the service company to assess and document:
Circulation pump:
– Single-speed or variable-speed?
– Age and condition
– Any signs of seal leaks, unusual noise, or reduced flow
– Estimated remaining service life
Filter:
– Type (sand, cartridge, or diatomaceous earth)?
– When was it last serviced (media replaced for sand; cartridge cleaned or replaced)?
– Condition of the filter tank and multiport valve (for sand filters)
Heater:
– Gas, electric heat pump, or solar?
– Age, model, and condition
– When was it last serviced?
– Any fault codes or performance issues?
Salt chlorine generator (if applicable):
– Age and model of the cell
– When was it last cleaned?
– What is the cell’s remaining estimated life?
Automation system (if applicable):
– What system is installed, and is it communicating correctly with all equipment?
– Is the software/firmware current?
How old is each piece of equipment, and what is its expected remaining life?
Knowing the age of your equipment lets you plan. Equipment approaching end of life should be in your maintenance budget — not a surprise expense.
Typical lifespans for pool equipment:
– Single-speed pump: 8–12 years
– Variable-speed pump: 10–15 years
– Sand filter: 15–25 years (media replaced every 5–7 years)
– Cartridge filter: 5–8 years for the cartridges; tank lasts much longer
– Gas heater: 7–12 years
– Heat pump: 10–15 years
– Salt cell: 5–7 years
– Automation system: 10–15 years
Questions About Pumps

Should I upgrade from a single-speed to a variable-speed pump?
Variable-speed pumps (VSPs) use a permanent magnet motor that can run at multiple speeds, matching the flow rate to the actual demand. Running at lower speeds during non-peak filtration periods uses dramatically less electricity — typically 50–80% less than a single-speed pump running at full speed.
Ask the service company:
– What is my current pump’s energy consumption?
– What would a variable-speed pump cost to install?
– What is the estimated energy savings per season?
– Does my pool’s plumbing support lower-flow filtration?
Variable-speed pumps typically pay for themselves in energy savings within 3–5 seasons in many regions.
What does the pump repair involve, and what is the cost?
For pump repairs, ask specifically:
– What is causing the problem (seal failure, motor failure, impeller damage, etc.)?
– What is the cost of the repair?
– How old is the pump, and does the repair cost justify it relative to replacement?
Questions About Filters
When was the filter last serviced, and what service does it need?
Sand filter: Sand media should be replaced every 5–7 years. The multiport valve (which controls backwash, rinse, and filter modes) requires periodic inspection and occasional valve replacement. Backwashing (reversing flow to clean the sand) should be done when the pressure gauge reads 8–10 PSI above clean pressure.
Cartridge filter: Cartridges should be cleaned periodically during the season (rinsing with a hose) and replaced every 2–3 years or when the cartridge fabric is damaged. Ask when the cartridge was last replaced.
DE (diatomaceous earth) filter: DE must be replaced after each backwash (the DE washes out with the backwash water). The grids inside the filter require periodic inspection and eventual replacement.
Questions About Heaters
What type of heater is most appropriate for my pool and usage?
Gas heater: The fastest heating option — can raise water temperature several degrees in a day. High operating cost in prolonged use. Best for pools that need to be heated quickly or seasonally. Requires natural gas line access.
Electric heat pump: Uses electricity to extract heat from the ambient air — very efficient when air temperatures are above approximately 10–15°C. Lower operating cost than gas for extended season use. Slower to heat from cold than gas. Requires outdoor air space around the unit.
Solar heating: Uses the sun to heat water circulated through roof-mounted panels. Very low operating cost but weather-dependent and slow. Best as a supplement to extend the season rather than as a primary heating source.
Ask the service company which type makes sense for your pool size, usage pattern, and existing utility connections.
My heater is making unusual noises / not reaching temperature / showing a fault code. What does this mean?
Ask the service company to diagnose the specific symptom:
- Fault codes: Should be looked up in the manufacturer’s service documentation — each code points to a specific component or condition
- Not reaching temperature: Could be undersized for the pool, a heat exchanger issue, ignition problems (gas), or refrigerant issues (heat pump)
- Unusual noises: Can indicate a pump issue (circulation through the heater), a heat exchanger issue, or combustion chamber issues (gas)
Ask for a specific diagnosis before agreeing to any repair.
Questions About Liner Replacement
What is the condition of my vinyl liner, and when will it need replacement?
Ask the service company to assess the liner:
- How old is it (if known)?
- Are there any areas of fading, brittleness, or loss of elasticity?
- Are there any bead channel areas where the liner is pulling away from the track?
- Are there any small holes, tears, or areas of wear?
Vinyl liners typically last 10–15 years. Signs of approaching end of life: significant fading, brittleness (the liner cracks or tears when touched rather than stretching), persistent leaks, or major bead channel failures.
Ask what a liner replacement would cost for your pool size and configuration, so you can plan.
