Top 5 Signs Your Pool Has a Leak

A small leak in your pool might not seem like a big deal—but left unchecked, it can lead to skyrocketing water bills, damaged equipment, and costly repairs. In Texas, where heat and evaporation are common, it can be tough to tell if you’re just dealing with a hot week or an actual leak. Here are the top five warning signs your pool may be losing water for all the wrong reasons.

1. Unexplained Water Loss

It’s normal for your pool to lose a small amount of water daily due to evaporation—especially in the Texas heat. But if you’re noticing a drop of more than 1/4 to 1/2 inch per day, it could point to a leak. Use the bucket test to determine if the loss is due to evaporation or something more serious.

Quick Tip:

Place a bucket on the pool step and fill it to match the pool’s water level. Wait 24–48 hours. If the pool water drops more than the bucket water, you likely have a leak.

2. Soaked or Sinking Ground Around the Pool

If the ground near your pool is unusually wet, mushy, or sinking, it might not be from splash-out. This can indicate an underground leak that’s saturating the soil. Over time, this can lead to erosion or damage to your pool’s structure and decking.

3. Sudden Spike in Water Bills

Have your utility bills jumped for no clear reason? Pool leaks can waste hundreds of gallons per day without you realizing it. If you’re constantly adding water and seeing higher bills, it’s worth investigating further.

4. Air or Bubbles in the Pool Return Line

If you see bubbles coming out of the return jets or hear your pump making gurgling noises, it could mean air is getting into the system due to a leak in the suction side of your plumbing. Left unresolved, this can lead to pump damage or inefficient filtration.

5. Algae Growth or Water Chemistry Issues

Is your pool suddenly turning green or requiring more frequent chemical balancing? A leak can dilute your water chemistry, making it harder to maintain proper chlorine levels. Algae loves inconsistent water conditions—making your pool harder to manage.
