Spotting a pool leak can be tricky, but there are a few signs to watch for:

• Water level drops: If your pool loses more than 1/4 inch of water per day, it could be a leak rather than evaporation.
• Wet spots: Check for soggy areas around the pool deck or equipment pad.
• Algae growth: Unusual algae blooms may indicate untreated water entering the pool.
• Cracks or gaps: Inspect the pool surface and tiles for visible cracks.

Using pool test kits can help monitor water chemistry, which may also reveal leaks if levels change unexpectedly.

One simple method is the bucket test:

1. Fill a bucket with pool water and place it on a pool step, making sure the water level inside matches the pool’s water level outside.
2. Mark both water levels with tape or a marker.
3. Wait 24 hours, then compare the levels. If the pool water drops more than the bucket, you may have a leak.

This test helps separate normal evaporation from possible leaks. For more detailed results, consider using pool test strips to check for chemical imbalances that might indicate water loss.

Test strips are mainly designed to check water quality, but they can be helpful in leak detection. If you notice sudden changes in chlorine, pH, or other chemical levels despite regular maintenance, it could suggest water is escaping and being replaced with untreated water. Regularly testing your pool with strips can help you spot these changes early, making it easier to investigate and address potential leaks before they become bigger issues.

It’s a good idea to check for leaks at the start of each swimming season and anytime you notice unusual water loss or changes in your pool’s chemical balance. Regularly using pool test kits or strips can help you monitor water quality, which may alert you to leaks if you see unexpected drops in chemical levels. Staying proactive can help you catch small leaks before they turn into bigger problems.

If you suspect or confirm a leak, here are some steps you can take:

• Pinpoint the source: Try to locate where the water is escaping—common spots include the liner, plumbing, or around fittings.
• Use a pool test kit: Monitoring water chemistry can help you track the leak’s impact.
• Contact a professional: For larger or hard-to-find leaks, it’s best to consult a pool service expert.

Addressing leaks quickly can help prevent further damage and keep your pool in great shape.
