Several factors may have an effect on the test results:  Running pool equipment, check valves that may not seal correctly, wind, rain, dog's drinking out of the tester, cannonballs, etc...

Here's how you can get the most accurate results out of your Mini Bucket Test pool leak detector

Turn off Auto-Fill System, and any water features such as waterfalls.

*We recommend starting the test with your pool pump running.  Run the pump for 24 hours during the test.  When you return to check the status of the water levels, make sure your pool pump is still running.  This gives the most consistent results. 

There are many more pool equipment configurations you can use but the above configuration should give you the basic "IS my pool leaking?" info you need before making the call to your pool professional for help.

Other factors such as wind, rain, pet's drinking out of the tester, etc... can play a small role in test results.

We hate to play the "duh" card, but common sense will help with testing during these conditions.

Wind:  If it's a bit windy, the closer the water is to the top of the Mini Bucket Test, the more accurate your results will be. 

Do not allow pets or people in the pool during the test. 

*Try to perform the test on a calm weather day vs any extreme weather day.  The calmer the weather, the more accurate the results.
