A little water loss is normal, especially during the hot Texas summer. High temperatures, low humidity, and frequent pool use all contribute to evaporation. However, when your pool is losing more water than expected, it could be a sign of a hidden leak.
Ignoring a pool leak can lead to expensive repairs, increased water bills, damaged equipment, and even structural issues. Knowing the warning signs can help you address the problem before it becomes more serious.
1. Your Pool Water Level Drops Quickly
Most pools lose about 1/4 to 1/2 inch of water per day due to evaporation, depending on weather conditions. If you’re adding water every few days or your pool is losing more than an inch per week, it’s worth investigating.
A simple bucket test can help determine whether the water loss is caused by evaporation or a leak.
2. Your Water Bill Suddenly Increases
An unexplained spike in your monthly water bill is often one of the first indicators of a hidden pool leak. Even a small crack or plumbing leak can waste hundreds or thousands of gallons of water over time.
If your household water usage hasn’t changed but your bill has increased, your pool could be the reason.
3. You Notice Wet or Soggy Areas Around the Pool
Soft, muddy, or unusually green patches of grass near your pool may indicate that water is escaping underground.
Underground plumbing leaks often go unnoticed because the water never reaches the surface of the pool. Instead, it saturates the surrounding soil, creating wet spots or erosion.
4. Cracks Are Forming Around the Pool
Water escaping beneath the pool can wash away soil and weaken the foundation supporting the pool structure.
Over time, this movement may cause:
- Deck cracks
- Pool shell cracks
- Shifting concrete
- Uneven pavers
Addressing a leak early can help prevent costly structural repairs.
5. You’re Constantly Adding Pool Chemicals
If your pool requires more chlorine, salt, or balancing chemicals than usual, fresh water may be continuously replacing treated water through a leak.
Constant dilution makes it difficult to maintain proper chemical levels and can increase your maintenance costs.
6. Air Bubbles Are Coming From the Return Jets
Air bubbles returning to the pool may indicate that your plumbing system is drawing air through a leak.
This often points to problems with:
- Suction lines
- Pump connections
- Valves
- Underground plumbing
A professional pressure test can help pinpoint the source.
7. Pool Equipment Runs More Often Than Normal
Automatic fillers and pool pumps may cycle more frequently if your pool is losing water.
Longer pump run times not only increase your energy bill but also put additional wear on expensive equipment.
8. The Pool Deck Is Sinking or Separating
When leaking water erodes the soil beneath the deck, sections of concrete may begin to settle unevenly.
Warning signs include:
- Gaps between the deck and pool
- Uneven concrete
- Loose coping
- Sunken deck sections
These problems often worsen if the leak isn’t repaired.
9. You See Algae Despite Proper Maintenance
Leaks introduce fresh water into the pool, making it harder to maintain balanced chemistry.
If algae keeps returning even after regular cleaning and chemical treatment, excessive water loss could be contributing to the problem.
10. You Suspect Something Isn’t Right
Many homeowners notice subtle changes before obvious damage appears.
You might simply find yourself thinking:
- “I’m adding water more often.”
- “The pool level keeps dropping.”
- “My equipment sounds different.”
- “Something feels off.”
Trust those observations. Catching a leak early is almost always less expensive than waiting for visible damage.
Why Pool Leaks Should Never Be Ignored
Even a small leak can waste thousands of gallons of water each month. Over time, that water can undermine your pool’s foundation, damage surrounding landscaping, increase utility bills, and shorten the life of your pool equipment.
Professional leak detection uses specialized tools such as electronic listening devices, pressure testing, and dye testing to locate leaks accurately without unnecessary digging or demolition.
