You are aware as a homeowner that wonderful things frequently involve big responsibility. For you, your loved ones, friends, and neighbors, you want your pool to be a secure place to swim. Therefore, it is your responsibility to maintain balanced chemistry in your pool.
The pH levels in your pool can be greatly impacted by rain, which might be dangerous for both the pool and anyone swimming in it. Because of this, it’s critical to be prepared for storms.
In this post, I’ll cover a variety of topics, including how rain affects your pool’s chemistry, how to inspect your pool after it rains, and how to get ready for the next downpour. Let’s start now!
How to Maintain Your Pool Before It Rains?
To keep your pool’s water clean and healthy if there will be a lot of rain, take the following preventative measures:
To keep the chemistry of your water in check, balance your pH and alkalinity in advance.
Add 1 to 2 ppm more chlorine to your pool than is usually suggested or required.
Always bear in mind that keeping your pool surfaces clean requires preventing algae. So, to prevent an outbreak of algae, keep an algaecide in the water.
Buff the surfaces of your pool. The walls and floor of your pool can benefit from routine brushing to help remove any minute algae particles that could otherwise circulate into the filter.
Always adhere to your scheduled filter cleanings. Follow the manufacturer’s cleaning recommendations when cleaning your pool filter.
How does a Storm Affect the Chemistry of Your Pool?
Your pool’s chemical balance needs to be maintained on a regular basis. To maintain a fun and secure swimming experience, it’s crucial to monitor the pH, alkalinity, chlorine, calcium hardness, calcium chloride, and other chemical levels. Not to mention an exquisite appearance that is crystal clear!
Did you know that chemicals in rainfall can become out of balance?
Perhaps you’re wondering, “Isn’t rainwater pure?” How might it harm my pool, you ask? You’re partially correct, I suppose.
Rainwater in pool will dilute the chemistry levels, lowering pH, alkalinity, hardness, stabilizer, and chlorine readings. Rainfall contains no chlorine. Furthermore, rainfall introduces small amounts of contaminants that are washed into the pool
On the pH scale, a scientific scale that defines how acidic or basic (also known as alkaline) water is, rain begins with a pure, neutral seven rating. However, as it falls from the sky, it is contaminated by the numerous gases that are emitted into the atmosphere by factories, fertilizers, cars, and other human activities.
Nitrogen oxide and sulfur dioxide (SO2) are the two most prevalent gases (NO2).
This kind of rain, known as “acid rain,” is harmful to both people and the environment, including, you guessed it, your pool.
Low pH values (below seven) indicate that acid rain is quite acidic. A swimming pool should have a pH of between 7.2 and 7.8.

Should You Drain Your Pool Water After It Rains?
Was it merely a light sprinkle or a brief downpour? The pool doesn’t need to be drained of any water at that point. But you should check the water to make sure it’s still balanced. If anything’s off, correct it as necessary.
However, suppose a significant thunderstorm caused a flood to pour into your pool to the extent that the skimmers aren’t even visible above the water line and water may even be spilling out onto the deck. In that case, the answer is probably yes. You need to remove some of the water immediately.
With that much water, the chemicals you put in your pool have probably been diluted and the amounts of sanitizer, alkalinity, pH and other things have changed.
Debris-like leaves and twigs—which probably fell into your pool during the storm—can’t get into the skimmer baskets if the skimmers are covered by a high water line. Instead, they will stay in the water and float around until enough water is taken out to let the skimmers work properly.
It’s time to remove some of the water from the pool after the weather has cleared.
Items Required for Storm and Rain Cleanup in The Pool
Make sure you have all the necessary equipment on hand to manage your pool water before you begin, or even as soon as the first drizzle of rain. It’s time to restore the clarity and blueness of your water as soon as the skies are once more clear and blue.
- Pool Chlorine Shock
- Adjusters for pH and Total Alkalinity (Alkalinity Up, Soda Ash, Dry Acid)
- Leslie’s Ultra Bright Advanced or Leslie’s Clear Aid)
- Enzymes and/or Phosphate Remover (Leslie’s Perfect Weekly)
- Leslie’s Stain and Scale Prevent, a stain and scale inhibitor
- Test strips or a pool test kit
- Skimmer Net or Leaf Rake
- The swimming pool brush and extension pole
- Pump Hose
- Pool Cleaner with Automatic or Manual Vacuum Head
What to Do with Pool When It Rains?
Heavy rains might overwhelm your pool by disrupting its chemical balance. Storms and flooding might bring other things into your pool. Dirt, debris, rainwater, and lightning can harm your pool’s water chemistry and equipment.
Quick cleanup reduces algae, murky water, discoloration, and excessive filter pressure. After a rainstorm, use this checklist to clean your pool. Remember to:
Verify Your Water Level
If you’re wondering what to do right away after it rains, check the water level in your pool. especially if there was a hurricane or significant storm.
It’s likely that your water level is much higher than where it ought to be, in the center of your skimmer opening. And when that occurs, everything is affected, including water chemistry and filtration.
Fortunately, resolving this minor issue is simple:
Drain your pool gradually to lower the level of the water if it has risen above the mid-skimmer level. You need your pool pump to accomplish that.
- Here’s how to empty a pool after it has rained:
- Set your pump to “Waste” or “Backwash.”
- Connect the backwash hose.
- Activate the pool pump.
Keep an eye on your water level as your pump empties water.
Once the water level reaches a mid-skimmer level, turn off the pump.
Make a small adjustment to the above procedure to jump-start cleaning: Connect your pool vacuum to your pool skimmer instead of merely running the pump to backwash the pool. After that, do two tasks at once by vacuuming the pool floor and lowering the water level.
Activate the Filtering System
It’s time to start your water circulating after your water level has been restored.
Important: Before turning on your pump once more, empty your pump and pool skimmer baskets. Put your pump in “FILTER” after that.
Start your pump and keep it going while you proceed to the next phase. While you keep working, some of the cleanings will be handled by your main drain.
Shock the Pool
We are aware that the question, “Should you shock your pool when it rains? Don’t worry; we are here to help you through the necessary steps.
While it’s not yet necessary to adjust your pool’s chemistry, it wouldn’t hurt to give your water a little boost. Your pool’s chlorine levels will be substantially lower after a lot of rain since it has to work harder to remove impurities.
The chloride that was lost due to the rain is replaced by a shocking pool after rain. Even though it will take more than one shock treatment to balance your water, it will still be working in the background while you keep cleaning your pool.
By doing this, your chlorine levels will be closer to the usual range when you do start modifying chemicals.
So shock your pool while continuing to run the pump.
And the answer is yes if you’re wondering if you can shock a pool while it’s raining. Just keep in mind that because precipitation contains additional toxins, it won’t be as effective as a shock in dry weather.
Get Rid of Surface Grit
If you notice anything floating on the water’s surface, remove it right away.
If you wait, it will eventually settle on the pool floor. Additionally, if you don’t vacuum it up, it will remain there, absorbing your chlorine and tainting the water you love to be so clear.
Only leaves, twigs, and insects make up the majority of pool surface debris. But the purpose of this is to make everything visible.
Take your skimmer, then fish out everything that is within your grasp.
You should equip your pool with an automatic skimmer to speed up future skimming. These useful add-ons attach to your pool’s return jets and stick out a little above the water’s surface to catch any floating trash.
Vacuum and Sweep the Pool Floor
It’s time to “dive down” to the pool floor after the water’s surface appears to be smooth.
But first, start by cleaning the stairs and walls. Even if they look clean, there is a good chance that they contain contaminants that are ready to grow and turn your pool into a cloudy, green mess.
After you’ve finished scrubbing, vacuum the pool floor by attaching your vacuum to the skimmer. For the greatest results, vacuum the entire pool length.
Put your automated pool cleaner in and proceed to the next step if you have one.
Use your brush to direct floor debris toward the main drain if you don’t have a vacuum. It will be sucked up by the main drain and sent directly to the filter.

Remove Some of The Pool’s Water
You have a few options if there is a lot of water in your pool but little to no debris and vacuuming the small quantity of trash to waste won’t get rid of all the water.
Once the pool has enough water removed, you can keep vacuuming the waste. Once more, the target is six to eight inches from the top of the pool, or halfway down the skimmer plate.
Alternately, you can halt vacuuming, leave the filter set to “waste,” attach a backwash hose to the filter’s waste port and activate the pump. Pump out water until the waterline reaches the desired level.
A sump pump connected to a garden hose is another option.
Check the Alkalinity and pH Levels
To ensure swimming is secure, a pool’s chemical balance is carefully monitored. Little additional rainwater will have a significant impact on the pH and alkalinity levels in the pool
However, it will require some chemical changes if there is a lot of rain, acid rain, or too many contaminants in the water. Regarding the pH and alkalinity of your pool, remember the following:
- pH: Your pH might decrease as a result of rain, particularly after a major storm.
- Alkalinity: acidic rain tends to make alkaline water more acidic since alkaline water has a higher pH than typical drinking water.
- Sanitizer: To help fight off any contaminants that may have entered your pool with the storm, the chlorine or alternative sanitizer needs to be at the proper level. If the rain diluted the levels, check them and add extra.
But there are instances when rain is a good thing. In some circumstances, rain can ease your maintenance problems since if your stabilizer or alkalinity levels are too high, the only way to lower them is by adding water.
Not that you would want to rely on this. To ensure the ideal swimming experience, you should always be in charge of controlling those levels.
Always test the water after rain to determine what changes need to be made.
Rebalance the Pool Water
Small amounts of rain, like.25″ and.5″, can temporarily lower your pool’s pH. Quickly, the right equilibrium is recovered. You’ll need to add chemicals as necessary and wait to make sure they don’t adjust too high after significant storms that add 2-3 inches of rainwater to your pool.
More than just adding chemicals will be needed to get your pool back in balance. To retest the water, you must first drain the pool to its regular level. When the water level is appropriate, adjust the pH or alkalinity as needed.
After a significant storm, many pool owners want to shock their pools after a significant storm, but this isn’t always necessary. Normally, shocking the pool is only necessary when the toxins from a devastating storm are at extremely high levels.
If you decide to shock your pool, there won’t be any damage done to it. However, don’t think of it as typical post-storm practice. Don’t be afraid to call a professional if you feel you need help testing and adjusting the levels in your pool.
Conclusion
You can keep your pool clean, healthy, and swimmable by being prepared for inclement weather and learning how to drain water from your pool after rain. If you’re organized, you can quickly resume swimming in your pool.
