Find out why your pool might be losing water, what you can do about it, and how our professional services keep your swimming pool clear, efficient, and fun all year long.

How Much Water Should a Pool Lose Overnight?

All pools lose some water, but how much is normal? On average, pools can lose about 1/8 to 1/4 inch of water per day due to evaporation, especially in the Victorville heat. If you notice a drop of more than this, especially inches of water overnight, something is wrong.

Having a reference point for normal water loss helps pool owners recognize excessive water loss—whether from evaporation, leaks, or both.

What Are the Main Reasons Pools Lose Water?

Pools usually lose water from two sources: evaporation and leaks. Evaporation is normal, especially in dry, hot, or windy climates. Frequent wind, high temperatures, and lack of a pool cover can cause water to evaporate faster than usual.

But if your pool loses water every night and the loss exceeds normal evaporation, you likely have a pool leak. Water can escape through cracks, broken fittings, leaking skimmer lines, or plumbing system failures.

Could Evaporation Be the Culprit for Pool Water Loss?

Evaporation is the most common source of daily pool water loss. Pool water evaporation rates depend on temperature, water movement, humidity, and pool size. Leaving your pool uncovered or running water features, like fountains, can make the pool lose more water than expected.

A simple way to check if water loss is due to evaporation: cover your pool overnight and compare water levels. If the pool still loses water, a leak might be present.

What Are Signs of a Leak Instead of Evaporation?

Excessive overnight water loss usually indicates a pool leak rather than evaporation. Watch out for these signs:

• A drop of more than 1/4 inch of water overnight
• Wet soil, soggy spots, or puddles around the pool
• Air bubbles in the skimmer or return lines
• Loss of water even when the pool pump is off
• Cloudy water, water loss in the spa, or unexplained constant topping-off

If you observe these issues, your pool is probably losing water due to a leak.

How Can You Tell if Your Pool Is Losing Water to a Leak?

To confirm a leak, try the bucket test. Place a bucket with water on a pool step (with the water level the same inside and outside), mark the water level inside and outside the bucket, and compare the difference after 24 hours. If the pool loses significantly more water than the bucket, a leak is likely.

Also, take note of how much water your pool loses per day during different conditions. Water loss that increases when the pump system is running may indicate a plumbing leak.

What Steps Should You Take for Leak Detection?

If you suspect a leak, call the pros. At GFC Pool Cleaning & Repair, we use Leaktronics' cutting-edge leak detection equipment to pinpoint leaks quickly and accurately—no guesswork needed. Our process includes:

• Advanced electronic listening tools to track water movement and dripping inside pipes
• Visual inspections of skimmers, main drains, fittings, and vinyl liners
• Pressure testing of pool plumbing for hidden leaks
• Dye tests around the pool and spa to confirm the location of leaks

Early leak detection prevents excessive water loss, protects your pool structure, and keeps your water bills in check.

How Does Pool Structure Affect Water Loss?

Cracks in the pool structure—on the sides, bottom of the pool, or around the skimmer and fittings—can lead to significant water loss overnight. Pool water can escape through small cracks that grow over time, causing more damage.

Regular pool maintenance, including visual checks for cracks and monitoring the water level in your pool, is key to early leak detection.

What About Vinyl Liner and Inground Pools?

Vinyl liner pools are especially susceptible to tears, pinholes, and fitting leaks. Check for wrinkles, bubbles, or discoloration—these can indicate a leak somewhere along the liner. For inground pools, shifting soil, settling, or improper installation can create leaks that are difficult to spot without professional help.

In both cases, using expert leak detection services is the most reliable way to locate and fix a leak fast.

Can Equipment or Fittings Cause Water Loss?

Leaking skimmers, pump system failures, cracked return fittings, or loose pipes in the pool pump system often cause pools to lose water overnight. Faulty pool equipment can also send water away from the pool when it should be circulating back into the pool.

If you notice water pooling near equipment or hear odd noises from pumps and filters, a leak inspection is essential.
