How to Know Why Your Pool Is Losing Water

One of the most common concerns among pool owners is water loss. In a climate like Florida’s, it’s normal for heat and wind to cause some evaporation. However, when the water loss is excessive or sudden, you might be dealing with a leak. We often get questions like: “How much water loss is normal for my pool?” or “How do I know if I have a leak?” Here are the key points to help you tell the difference and know when it’s time to call a professional.

Natural evaporation: how much is normal?

In Florida, a pool can lose between 1/4 to 1 inch of water per day due to evaporation, especially during the hotter, drier months. Factors like direct sun exposure, wind, and water temperature influence this process.

If your pool is losing less than an inch of water in 24 hours, it’s likely due to normal evaporation.

Signs you may have a leak

• Constant loss of more than 1 inch per day

• Wet or soggy areas around the pool

• Visible cracks in the pool surface or deck

• Air in the filtration system

• Difficulty maintaining the water level, even when refilling regularly

The bucket test: simple and effective

A quick way to tell whether the water loss is due to evaporation or a leak is to perform the bucket test:

1. Fill a bucket with water and place it on the first step inside the pool, matching the water level inside the bucket with the pool water outside.

2. Mark the water level inside and outside the bucket.

3. Wait 24 hours without using the pool.

4. If the water level outside the bucket has dropped more than the level inside, it’s likely a leak.
