How to Check for Pool Leaks: A Complete Guide for Lanzarote Pool Owners

Is Your Swimming Pool Losing Water?

If you've noticed your pool water level dropping faster than usual, you're not alone. Many pool owners in Lanzarote face this problem, especially during the hot summer months. But how do you know if it's evaporation or an actual leak?

In this comprehensive guide, we'll show you how to check for pool leaks using simple DIY methods, and explain when it's time to call professional leak detection services.

Understanding Pool Water Loss

Before panicking about a potential leak, it's important to understand that some water loss is normal:

• Evaporation: In Lanzarote's warm climate, pools can lose 3-7mm of water per day through evaporation
• Splash-out: Active swimming and play can cause significant water loss
• Backwash: Filter cleaning removes water from your pool
• Wind: Lanzarote's trade winds accelerate evaporation

If you're losing more than 5cm of water per week, you likely have a leak that needs attention.

The Bucket Test: Your First Step

The bucket test is the most reliable DIY method to determine if your pool is leaking or just evaporating water. Watch this excellent video from Swim University that demonstrates exactly how to perform the test:

Step-by-Step Bucket Test

1. Bring your pool water to normal level before starting the test
2. Fill a 5-gallon bucket with pool water to about one inch from the top
3. Place the bucket on the first or second step so the water temperature matches
4. Mark the water level inside the bucket with tape or marker
5. Mark the pool water level on the outside of the bucket
6. Wait 24 hours without using the pool or running any equipment
7. Compare the levels - if the pool level dropped more than the bucket level, you have a leak

Interpreting Your Results

• Equal drop: Normal evaporation - no leak detected
• Pool dropped more: You have a leak - time for professional leak detection
• Pool dropped significantly more: Serious leak requiring immediate attention

The Dye Test: Locating Visible Leaks

If you suspect a leak near fittings, lights, or visible cracks, the dye test can help confirm:

1. Turn off all pool equipment
2. Let the water become completely still
3. Use food colouring or leak detection dye
4. Squirt dye near suspected areas
5. Watch if the dye is pulled into any cracks or gaps

Pro tip: This test works best on calm days with no wind.
