If you’ve noticed your pool water level dropping faster than usual, you may be dealing with a pool leak. While some water loss is normal due to evaporation, excessive water loss can signal a more serious problem.
In this guide, we’ll explain how to identify a pool leak, common causes, and when to call a professional in New Jersey.
How Much Water Loss Is Normal?
A pool can lose about ¼ inch of water per day due to evaporation, especially in warm weather.
If you’re losing more than that, it could indicate a leak.

Signs Your Pool Might Have a Leak
Here are the most common warning signs:
- The water level is dropping quickly
- Cracks in the pool structure or decking
- Wet spots around the pool area
- Air bubbles in return lines
- Constant need to refill the pool
- Increased water or chemical usage
These signs should not be ignored, as leaks can worsen over time.
Common Causes of Pool Leaks
Pool leaks can happen in different areas:
1. Plumbing Leaks
Pipes underground or near equipment can crack or loosen over time.
2. Structural Cracks
Concrete or vinyl pools may develop cracks that allow water to escape.
3. Equipment Issues
Leaks can occur in:
- Pump
- Filter
- Heater
- Valves
4. Worn Seals & Fittings
Skimmers, returns, and seals can deteriorate and start leaking.
Simple Leak Test (Bucket Test)
You can do a basic test at home:
- Fill a bucket with pool water
- Place it on a pool step
- Mark the water levels inside and outside
- Wait 24 hours
If the pool water drops more than the bucket → likely a leak
Why You Should Fix Pool Leaks Quickly
Ignoring a leak can lead to:
- Structural damage
- Soil erosion around the pool
- Higher water and chemical costs
- Equipment damage
