Pool Is Losing Water Overnight? Discover Why Your Swimming Pool Water Level Is Dropping in Austin

Is your pool water level dropping faster than you expect—especially overnight? If your swimming pool is losing water and you’re in Austin, TX, you’re not alone. Many pool owners notice unexplained water loss, and while some causes are harmless, others may require urgent attention. This article dives into the reasons why your pool is losing water, how to tell the difference between normal evaporation and a leak, and what you can do to fix the problem. As Leak Finder Pro, Austin’s leading pool leak detection specialists, we’ll show you how our expertise and industry-leading LeakTronics equipment can help you keep your pool in top shape.

Why Is My Pool Water Level Dropping?

If your pool is losing water, the first step is to figure out if the water loss is normal or a sign of a bigger problem. In Austin, pool water loss can be caused by evaporation, splash-out, backwashing, or a pool leak. While some water loss is expected, a sudden or significant drop in water level can signal a leak that needs immediate attention.

How Much Water Loss Is Normal in Austin?

In Central Texas, it’s common for a pool to lose 1/8 to 1/4 inch of water per day due to evaporation—sometimes more during hot, windy, or low humidity days. If your pool loses more than 2 inches of water every week, or if you’re adding water to the pool more often than usual, it’s time to investigate further. Remember, using a pool cover can dramatically reduce water lost to evaporation.

What Causes Pool Water Loss Overnight?

If your pool is losing water overnight, the most common reasons are:

• Evaporation: Warm days and cool nights can accelerate pool water evaporation.
• Leaks: Cracks, faulty plumbing, or equipment issues can cause significant water loss overnight.
• Splash-Out: Less likely at night, but can add up if you have lots of pool activity during the day.

If the water level continues to drop overnight while the pool is not in use, you may have a leak in your pool.

Is It Pool Evaporation or a Leak?

The best way to tell if your swimming pool water loss is due to evaporation or a leak is the bucket test:

1. Fill a bucket with pool water and place it on a pool step.
2. Mark the water level inside and outside the bucket.
3. Wait 24 hours (overnight is ideal).
4. If the pool water level has dropped more than the water level in the bucket, you may have a leak.

If the pool water level has dropped but the bucket level has not, it’s very possible that you have a leak. If both have dropped at the same rate, the cause is almost certainly evaporation.

How Does Austin’s Climate Affect Pool Water Loss?

Austin’s hot summers, low humidity, and frequent sunshine increase the rate of pool water evaporation. Windy days and direct sunlight can cause your pool to lose even more water. Shading your pool, installing windbreaks, or using a pool cover can help reduce evaporation and keep your pool’s water level stable.

What Are the Signs of a Pool Leak?

Look for these signs your pool is leaking:

• The water level drops more than 1/4 inch per day.
• You see wet spots or soggy ground around the pool.
• Air bubbles in the pool pump system.
• Cracks in the pool surface or tile line.
• Water level stops dropping at a certain point (often at the skimmer or light).
• Higher than normal water bills.

If you notice any of these, your pool may have a leak that needs professional leak detection.

How Can I Test for a Pool Leak at Home?

Besides the bucket test, try these steps:

• Inspect the skimmer, pool filter, and pool heater for visible leaks.
• Look for cracks or gaps along the water line, bottom of the pool, and around the pool equipment.
• Use food coloring near suspected leak areas—if the dye is drawn into a crack, you’ve found the source of the leak.

If you can’t find the leak, or if the water loss is significant, contact Leak Finder Pro for expert pool leak detection in Austin.

Where Are the Most Common Pool Leak Locations?

Pool leaks can occur in several places:

• Skimmer: Cracks or separation from the pool wall.
• Return lines and plumbing: Underground leaks can cause soggy spots around the pool.
• Pool lights and fittings: Gaps around lights or jets.
• Pool shell: Cracks in concrete, gunite, or vinyl liners.
• Pool equipment: Leaks in the pool pump, pool filter, or pool heater.
