How to Tell If Your Pool Has a Leak (And What to Do About It)

A small leak in your pool might not seem like a big deal—but over time, it can lead to skyrocketing water bills, equipment damage, and costly structural repairs. Whether you own a pool in Toronto, Vaughan, Mississauga, or anywhere in the GTA, knowing how to identify and address a leak early can save you thousands.

At AquaCare Pools, we’re often called to investigate what homeowners initially assume is just evaporation—only to discover a hidden pool leak that’s gone undetected for weeks. Here’s how you can tell if your pool has a leak, and what steps to take if it does.

💧 How to Tell If Your Pool Has a Leak

1. You’re Losing More Water Than Usual

It’s normal for pools to lose about 1/8 to 1/4 inch of water per day due to evaporation—especially during hot, dry, or windy weather. But if you’re noticing more than an inch of water loss per week, there could be a leak.

📍Pro Tip: Perform the bucket test:

• Fill a bucket with pool water and place it on a pool step.

• Mark the water level inside the bucket and on the pool wall.

• Wait 24–48 hours.

• If the pool water level drops more than the water in the bucket, you likely have a leak.

2. There Are Wet Spots Around the Pool Area

Puddles or soggy areas around the pool—especially when it hasn’t rained—may point to an underground plumbing leak. Water escaping from return lines, skimmers, or main drains often shows up in the surrounding soil or deck.

3. Your Pool Is Using More Chemicals Than Usual

Leaks dilute the water in your pool, which means your chemical balance will be off. If you’re constantly adding chlorine, balancing pH, or struggling with algae growth, a leak could be the culprit.

4. You Notice Air in the Pump or Bubbles in the Return Jets

If you see air bubbles coming through the return jets or your pump is struggling to maintain pressure, it may indicate a leak in the suction side of your plumbing. This is common in underground pipes or cracked fittings.

5. Cracks or Shifting Tiles in the Pool Structure

Visible cracks in the pool liner, tile, or concrete surface can allow water to seep through. Even small hairline cracks can turn into big problems if not addressed early.

🛠️ What to Do If You Think Your Pool Is Leaking

1. Confirm the Leak

Use the bucket test to confirm water loss. If you’re unsure, take photos of the water level over several days and note any changes.

2. Check the Equipment Pad

Inspect your pump, filter, heater, and plumbing connections for any signs of dripping or pooling water.
