Heavy Rain Recovery - Pool Clean-Up Checklist

Heavy Pool Rain Recovery

How to Clean Your Pool After a Heavy Downpour

Heavy rains can overwhelm your pool by significantly altering the chemical balance with the introduction of new water. Unfortunately, rain water is not chemically balanced, so it will negatively impact the pool water chemistry - potentially causing staining, scale and even algae growth. Flooding or pooling water can also wash dirt and other debris into the pool increasing your risk of staining and or damaging your equipment.

You can trust the experts at Leslie’s to help you get your pool cleaned up after a storm!

Clean-Up Checklist

  1. Remove large debris from the pool surface and floor using a cleaning attachment, like a leaf rake or skimmer net.
  2. Empty dirt and debris from the skimmer basket and pump basket.
  3. Turn on the pump to verify that the circulation system is operational.
  4. Check the water level. If the water is higher than the middle of the tile or skimmer opening, lower the level with a submersible pump or multiport backwash valve set to 'waste' position (if using a sand filter).
  5. Vacuum dirt from the pool floor and walls with an automatic pool cleaner or manual pool vacuum.
  6. Brush the pool thoroughly with the appropriate brush for your pool surface. Find different pool brushes HERE.
  7. Run your pool pump and filter continuously until the pool returns to the normal condition.
  8. Backwash or clean your filter when pressure is 8-10 psi above starting pressure.

Chemical Balance

  1. Test your water using a test kit or test strips. Check the water balance and sanitizer level. The pH should be adjusted to the 7.4 to 7.6 range. Adjust the Total Alkalinity to 80 to 120 ppm based upon the type of sanitizer used.
  2. The Free Available Chlorine (FAC) level should be raised to the 5.0 to 10.0 ppm range. Here are the dosages of chlorine required (ppm increase is approximate):
    1. Leslie’s Chlor Brite (sodium dichlor): 1 lb. in 10,000 gallons of pool water provides 7.4 ppm.
    2. Leslie’s Power Powder Plus (cal hypo-70% Available Chlorine): 1 lb. in 10,000 gallons of pool water provides 9.4 ppm.
    3. Liquid chlorine (sodium hypochlorite-10% Avail. Chlorine): 1 gallon in 10,000 gallons of pool water provides 10.0 ppm.
  3. Add Leslie’s Clear Aid to help remove small particles and organic material in the water that can make the water look cloudy.
  4. If applicable, add Leslie’s Scale & Stain Remove to prevent staining. (Strongly recommended for salt systems)
  5. Bring a water sample to your local Leslie’s store for free testing and analysis. Pay extra attention to the Phosphate level as this will typically spike after heavy rains causing an increased probability of an algae bloom.
  6. When chemicals are in balance, resume application of Perfect Weekly.

No Electricity? Here's what to do:

  • Use a leaf rake to remove large debris from the pool.
  • If your tap water service works, use a leaf bagger with a fine mesh bag to remove small dirt particles.
  • Superchlorinate your water with liquid chlorine or Leslie’s Chlor Brite to maintain a FAC level of 5.0-10.0 ppm.
  • If any of your pool’s major equipment, such as the pump, filter, or heater, is damaged in the storm, call 1.800.LESLIES to schedule an appointment with one of Leslie’s trained, professional Service Technicians. We repair and install all types of major pool equipment and can get your pool up and running quickly.
