How To Clean My Pool After A Storm Or Flood?

🌧️ How to Clean Your Swimming Pool After a Storm or Flood

âś… 1. Turn Off All Equipment

  • Turn off the pump, filter, chlorinator, and heater at the breaker if needed.

  • Avoid running equipment with heavy debris or dirty water—it can cause damage.

âś… 2. Remove Debris Manually

  • Use a leaf skimmer or net to remove:

    • Branches

    • Leaves

    • Toys or trash

  • Avoid using the pool vacuum until large debris is cleared to prevent clogging.

âś… 3. Clean Skimmer and Pump Baskets

  • Remove all debris to ensure good circulation once you restart the system.

âś… 4. Check and Clean the Filter

  • Cartridge filter: Remove and hose it off.

  • Sand or DE filter: Backwash thoroughly.

  • Repeat cleaning daily if the water is heavily contaminated.

âś… 5. Test and Balance the Water

Storms can wash contaminants into the pool and dilute chemicals:

  • pH: 7.2–7.6

  • Alkalinity: 80–120 ppm

  • Chlorine: 1–3 ppm

  • Adjust as needed before shocking.

âś… 6. Shock the Pool (Superchlorinate)

  • Use a chlorine shock or non-chlorine oxidiser.

  • Run the pump for 24–48 hours continuously.

  • Shock again in 24 hours if water is still cloudy or smells bad.

âś… 7. Brush and Vacuum

  • Brush walls and floor to remove dirt or algae.

  • Vacuum manually (or use a robotic cleaner if safe).

  • For flood-contaminated pools, vacuum to waste if possible to avoid recirculating muddy water.

âś… 8. Run the Pump Until Water Clears

  • Keep the system running non-stop until the pool is clear.

  • Clean or backwash the filter regularly during this process.

âś… 9. Add Clarifier or Flocculant (Optional)

  • Use a pool clarifier if the water is just cloudy.

  • Use a flocculant if the water is very dirty and full of fine particles (requires manual vacuuming after settling).

âś… 10. Final Water Balancing

  • Once clear, recheck water chemistry.

  • Add necessary chemicals to restore proper balance.

  • Reinstall automatic chlorinators or salt cells if removed.

⚠️ If Flood Water Entered the Pool:

  • Assume contamination from sewage, pesticides, or bacteria.

  • Drain partially or fully (if permitted) and refill.

  • Use high-dose chlorine and test for phosphates or bacteria before swimming.
