End of Summer Pool Maintenance Checklist for McKinney, TX

Labor Day passes, the kids go back to school, and your McKinney pool goes from daily use to sitting untouched for days at a time. The temptation is to relax your maintenance routine — less swimming means less chemical demand, less debris means less skimming, less heat means less chlorine consumption. All of that is true. But "less maintenance" is not "no maintenance," and the transition from summer to fall is where most McKinney pools start accumulating the problems that become expensive in spring.

Pools in Craig Ranch, Stonebridge Ranch, Adriatica, and Tucker Hill don't shut down for winter the way pools do in colder climates. They stay filled, the pump keeps running (at reduced hours), and chemistry continues to shift — just slower. The end-of-summer checklist isn't about closing the pool. It's about transitioning it to a lower-maintenance mode that keeps everything stable through fall and winter without requiring a full recovery when spring arrives.

Equipment Assessment — Do This Before Off-Season

September is the ideal time to assess equipment because you've just put it through five months of peak-season stress. Any component that's going to fail in the next 6-12 months is showing signs now.

Pump

Listen to it for 60 seconds. Compare the sound to what you remember from June. If there's a new grinding, screeching, or vibration, the bearings or motor are wearing. Bearing noise in September becomes pump failure by February — and a pump that dies during a freeze causes damage far beyond the pump itself.

Check the pump strainer basket area for leaks, especially around the lid O-ring and the shaft seal area (where the motor meets the pump housing). Any moisture that wasn't there in spring indicates a seal beginning to fail.

Decision point: If the pump is over 10 years old and showing any wear signs, schedule replacement in October-November when contractor availability is better and you can choose a variable speed upgrade on your timeline rather than as an emergency.

Filter

Deep clean the filter regardless of type. This is your annual reset:

• Cartridge: Full chemical soak (TSP for organics, then acid for minerals). Inspect for tears, collapsed pleats, and permanent discoloration. Replace if it's been 2+ years or if cleaning doesn't restore pressure to near-baseline.
• Sand: Backwash thoroughly. If the sand is 5+ years old, consider a media change before winter. Old sand channels and won't filter effectively for the spring startup.
• DE: Full breakdown, grid inspection, and recharge with fresh DE. Check for torn grids.

Heater

If you plan to use the heater for fall and early winter swimming (water temperatures below 80°F start in October in McKinney), inspect it now. Open the cabinet, check for insect nests and debris in the burner tray, verify ignition works, and run it for 15 minutes to confirm it heats and cycles properly. It's easier to schedule a heater repair in September than to discover it's broken on the first cold weekend you want to swim.

Salt Cell

End of summer is the ideal time for a thorough acid cleaning. The cell has been running at peak output for months, and even with self-cleaning cycles, calcium buildup accumulates over a full summer in McKinney's hard water. A clean cell going into the low-demand fall season extends cell life by reducing stress on scaled plates.

Chemistry Transition — September Adjustments

Lower Chlorine Target Slightly

Summer maintenance at 2-3 ppm can back off to 1.5-2.5 ppm as water temperatures drop below 85°F and bather load decreases. You'll use less chlorine through fall and winter — adjust your weekly dose or salt cell output accordingly.

Don't drop below 1 ppm at any point. Algae growth slows in cooler water but doesn't stop, and a pool that drifts to zero chlorine in October will have established algae by November that's harder to treat in cold water.

Test CYA and Consider a Partial Drain

If you've been using stabilized chlorine (trichlor tablets) all summer, your CYA has been climbing. September is a good time to test it. If CYA is above 60-70 ppm, a partial drain and refill now — before winter rain adds more dilution unpredictably — resets the CYA level for next season.

Draining in September also takes advantage of lower water rates compared to summer peak pricing and cooler temperatures that make the outdoor work more comfortable.

Balance Alkalinity and pH for Stability

Going into the low-maintenance months, set your chemistry for stability rather than perfection:

• pH: 7.4 (mid-range, less likely to drift to extremes in either direction)
• Alkalinity: 90-100 ppm (strong buffer to resist pH swings from fall rain)
• Calcium hardness: Test and note it. If it's above 400 ppm, plan a partial drain before next summer.

Physical Maintenance — The Fall Transition

Address Leaf Management Before It Starts

McKinney's mature trees — pecans, oaks, elms — start dropping leaves in October. In neighborhoods like Stonebridge Ranch and Adriatica where canopy coverage is dense, the leaf volume can overwhelm a skimmer within hours on a windy day.

Before leaf season:

• Trim overhanging branches back 5-10 feet from the pool edge. This is the single highest-impact thing you can do to reduce fall leaf load.
• Consider a leaf net — a mesh cover that sits above the pool surface and catches leaves before they hit the water. You pull it off periodically, dump the leaves, and put it back. Much easier than skimming leaves daily.
• Clean and inspect your pool cleaner. Make sure it's in working order before the heavy debris season starts. A robotic cleaner running daily during fall keeps settled debris from accumulating on the floor and staining the plaster.

Clean the Tile Line

End of summer is the best time for a waterline tile cleaning. Summer evaporation and chemical contact leave calcium deposits and organic staining on the tile. Cleaning it now — with a pumice stone for calcium or a tile cleaner for organic staining — prevents the buildup from hardening through winter into a much tougher removal job in spring.

For McKinney pools with hard water, the calcium ring from summer evaporation can be significant. An annual tile cleaning keeps it manageable; skipping it for two or three years turns a 30-minute job into a professional bead-blasting expense.

Inspect the Pool Deck

Before winter ground movement begins (North Texas clay soil expands with fall/winter rain), inspect the deck for new cracks, displaced coping, and failed caulk joints. Address them now:

• Seal hairline cracks with flexible concrete filler
• Re-caulk the coping joint where it's separated
• Note any structural cracks for monitoring through winter

Addressing these before the wet season prevents water from penetrating the concrete and causing freeze-thaw damage that widens cracks over winter.

Adjust the Pump Schedule

Reduce pump run time from the summer schedule (10-12 hours) to a fall schedule (6-8 hours). As water temperature drops, chemical demand decreases and one full turnover per day is usually sufficient.

Keep the pump running during the warmest part of the day (10 AM - 6 PM) to maintain UV-period circulation and skimmer operation during the hours when debris is most likely to blow into the pool.

Critical: Don't turn the pump off entirely during fall. Stagnant water develops issues quickly — even in cooler temperatures. Minimum run time through fall and winter is 4-6 hours per day, increasing to 24/7 during any freeze event (below 35°F).

The End-of-Summer Cost Check

September is a good month to audit what you spent on pool maintenance during the summer and identify unnecessary costs:

• Were you buying chemicals you didn't need? Algaecide when chlorine was adequate? Clarifier when the real issue was a dirty filter?
• Was your electricity cost higher than it should be? A single speed pump running 12 hours in August on an Oncor tiered rate is expensive. If this was the case, the off-season is the time to plan a variable speed pump upgrade for next year.
• Did you have any emergency repairs? What caused them? Could preventive maintenance have avoided them?

Using September as an annual review point helps you start the next season more efficiently — with the right chemicals, the right equipment, and a maintenance plan that accounts for what you learned this year.
