The Weekly Pool Maintenance Checklist Pool Techs Actually Use
A 30-minute weekly routine that keeps water clear and equipment healthy — plus the monthly and seasonal checks most owners forget.
Key takeaways
- Test free chlorine and pH two or three times a week; everything else monthly.
- Brushing is the most skipped step — and the one that prevents algae.
- Write down your filter’s clean pressure; clean it when it climbs 8–10 psi.
- A consistent routine costs less than any clean-up.
Professional pool techs can service a residential pool in 20–30 minutes because they do the same things, in the same order, every visit. Steal their routine and your pool will rarely surprise you.
Every visit (2–3 times per week)
- Test free chlorine and pH. These two move the fastest. Adjust as needed.
- Skim the surface. Leaves that sink become stains and chlorine demand.
- Empty the skimmer basket. A full basket starves the pump of water.
- Check the water level. It should sit about halfway up the skimmer opening.
Once a week
- Brush walls, steps and floor. Toward the main drain, paying extra attention to shady corners, behind ladders and around lights.
- Vacuum. Or check that your automatic cleaner is actually covering the whole floor.
- Empty the pump basket. Turn the pump off first and check the lid o-ring.
- Read the filter pressure. If it is 8–10 psi above the clean reading, backwash or clean the filter.
- Clean the waterline. A soft sponge and a tile cleaner made for pools keep body oils from building into scum.
- Walk the equipment pad. Look for drips, listen for new noises, and make sure nothing is too hot to touch.
Once a month
- Full water test: total alkalinity, calcium hardness, CYA and salt (if you have a salt cell). Run the LSI calculator to check overall balance.
- Inspect the salt cell for white scale and clean it only if needed, following the manufacturer’s instructions.
- Check timers and schedules — power outages and daylight saving changes reset many controllers.
- Inspect the surface for stains, rough spots, cracks, blisters or peeling.
Seasonally
- Deep-clean the filter (chemical cartridge cleaner or a DE grid teardown).
- Service the heater and check for scale or critter nests.
- Lubricate o-rings and check valve diverters.
- Check safety equipment: gates self-close and latch, covers are intact, drain covers are secure and in date.
How long should the pump run?
Most residential pools need enough run time to pass the full volume through the filter once a day (one turnover). Variable-speed pumps do this most efficiently by running longer at a lower speed — see our pump guide. Find your volume with the pool volume calculator.
A note on your phone with the date, readings and what you added turns pool care from guesswork into pattern recognition. You will spot a slow leak, a dying salt cell or rising CYA weeks before they become problems.
