Why Doesn’t My Pool Water Level Change After Rain?
Many homeowners notice little to no change in their pool’s water level after rain. This is the result of pool design, evaporation, drainage, and the size of most pools. In Southeast Florida, even a downpour may only cause a minor shift at your pool’s tile line.
- Large Surface, Small Change: Rain is spread across a big surface. Unless the rainfall is very heavy, most pools only see a slight increase.
- Evaporation & Wind: Warm, breezy weather quickly evaporates water, offsetting rainfall.
- Drainage: Some rain is directed away by your pool deck and landscaping.
Does Rain Affect Pool Water Chemistry?
Absolutely! Even if the pool water level looks stable, rain can dilute and alter the chemistry:
- Lower pH and stabilizer levels (rain is slightly acidic).
- Reduced chlorine, allowing for algae and bacteria growth.
Tobia Pool Care recommends:
- Test and adjust pH and chlorine after any significant rain.
- Brush and skim your pool to remove debris or algae.
- Run your filtration system to clear contaminants.
What Should Pool Owners Do After Rain?
Use this checklist after any rain event:
- Test water with a strip or meter.
- Adjust pH and chlorine if needed.
- Empty baskets and remove debris.
- Check that the pump and filter are running well.
- Inspect skimmer and drain covers.
- Look for wet spots near the deck.
Rain vs. Evaporation – Can It Cancel Out?
Yes! In Florida’s climate, evaporation and wind can “erase” light rain showers. Sometimes, water loss and gain match, so the tile line hardly moves.
Should You Run Pool Equipment After Rain?
Definitely run your pump and skimmer after storms:
- Circulate water to restore chemical balance.
- Vacuum and clear baskets.
- Backwash the filter if pressure is high.
Could A Leak Be Hiding?
If your autofill is running or you notice water level concerns even with regular rain, a slow leak may be masking symptoms. Tobia Pool Care offers professional leak detection and repair alongside our cleaning services—call us for an inspection.
