The Mini Bucket Test is a simple first-step tool that helps pool owners compare normal evaporation to possible leak-related water loss. It is designed to sit on your first swim step so you can compare the water level inside the tester to the water level in the pool outside it after 24 to 48 hours.

The test works by creating a side-by-side comparison. You place the Mini Bucket Test on your first swim step and fill it so the water level inside the tester exactly matches the water level of the pool outside it. After 24 to 48 hours, you compare the two levels.

• If the pool water level drops more than the water inside the tester, your pool may have a leak.
• If both levels stay about the same, evaporation is the more likely explanation.

No. The Mini Bucket Test is a first-step diagnostic tool. It does not pinpoint the exact location of a leak. What it does do is help you decide whether your water loss may be more than normal evaporation and whether further investigation may be worth it.

1. Turn off your auto-fill system and any water features such as waterfalls or spillovers.
2. Place the Mini Bucket Test on the first swim step of your pool.
3. Fill it so the water level inside the tester exactly matches the pool water level outside it.
4. Wait 24 to 48 hours.
5. Compare the two water levels.

For the most consistent results, we recommend starting the test with your pool pump running, letting it run during the test, and making sure it is still running when you return to compare the water levels. This tends to create more consistent testing conditions.

Turn off your auto-fill system and any water features such as waterfalls, fountains, or spillovers before starting the test. These can affect water movement or add water in ways that interfere with the comparison.

Yes. Wind, rain, and other outdoor conditions can influence the comparison. Calmer conditions usually lead to better results.

• Try to perform the test on a calm weather day.
• Avoid testing during heavy wind or rain when possible.
• If it is a little windy, keeping the water inside the Mini Bucket Test closer to the top can improve the comparison.

Yes. Pets drinking from the tester, people swimming, splashing, or anything else that disturbs the water can affect the results. For a cleaner comparison, do not allow pets or people in the pool during the test period.

The Mini Bucket Test is designed to fit most pools, but some pools have deeper steps than others. If your first swim step is too deep, you still have options:

• Wait until the pool water level drops naturally to a more testable height.
• Place the Mini Bucket Test on a stable object such as a block or brick to raise it into position.

In most cases, 24 to 48 hours is enough to compare the water levels and get useful information.

Real-world pool conditions are not always perfect. Wind, rain, pool equipment, check valves that do not seal correctly, splashing, pets, and other small factors can all affect the test. If the result is unclear, try the test again under calmer, more controlled conditions.

If the pool water drops more than the water inside the Mini Bucket Test, that may indicate leak-related water loss. At that point, you can decide whether it makes sense to take the next step and contact a pool professional for deeper leak investigation.
