How to Restore Your Pool Water After a Rainstorm

In New England, you never know what the weather will be. A sunny day can quickly turn into a rainy afternoon, with thunderstorms a common occurrence during the spring and summer months. You’re best bet is to prepare for everything, whatever the weather.

If you experience a rainstorm, there are a few steps you will want to take to keep your pool clean, balanced and filled with the optimal amount of water.

1. Check Your Chemicals

Rainwater in the United States is considered acid rain, which means it can adversely affect the pH, alkalinity, total dissolved solids, and calcium hardness levels in your pool water. Rainwater can also dilute your sanitizer. It is necessary to control any contaminants, so make sure to check the sanitizer levels. If you have a salt water pool, salt will also be diluted by rain. Runoff water from your yard or pool deck, debris, and even lightning can cause your pool water to become unbalanced.

2. Start the Cleanup

Start the cleanup process by cleaning out your skimmer and pump baskets. This will make the job easier for the next steps; turning on your pump and filter and skimming the surface of your pool water. Run your pump and filter while skimming to remove both large debris and smaller particles. Windy storms can often blow leaves, sticks and other brush into your pool that will need to be removed. Brush the walls, steps and ladders in your pool and vacuum to clean up whatever you may have missed with the skimmer and filter. If you have an automatic/robotic pool cleaner, you may want to use that unless there is significant debris. If there is, you may be better off with a manual pool vacuum.

3. Perform the Balancing Act

With a clean pool, you are ready to re-balance the chemicals in your pool water. We recommend that you test your pool water after any significant rainstorm. A light rainstorm should not greatly affect your pool chemical levels, but it never hurts to check to be certain they are in the proper range. Your chlorine and sanitizer levels should also be monitored to avoid contaminants that could lead to cloudiness or algae growth.

4. Administer Shock

It may not be crucial to shock your pool after a rainstorm, but it can be beneficial to remove any left over contaminants. Drain your pool water to the correct levels and check your chemicals before administering a shock treatment. Shock your pool in the evening after a rainstorm, once you have performed the preceding steps.

Follow these steps and you’ll be back to swimming in your pool in no time!
