Bucket test for a pool leak
A bucket test is a still-water comparison: you mark the pool waterline and a bucket sitting on a step, then check both after a quiet stretch. If the pool drops more than the bucket, a leak is more likely than weather. Phoenix heat and wind make this useful. It is still not a locate.
What the test is actually comparing
The bucket and the pool share the same air, sun, and wind. Water that leaves both at the same pace is mostly weather. Extra drop in the pool is water leaving somewhere the bucket cannot — a shell fitting, a light niche, a skimmer throat, or a buried line.
Turn the pump and autofill off if you know how. A running feature or a stuck fill valve ruins the comparison. Write the conditions if you later request unexplained water-loss help.
Why Phoenix weather fools a glance
Valley summers take visible water from heat and dry wind alone. A full-looking pool on a July afternoon can still have lost a band overnight. Autofill then hides a real leak under that same weather.
A still night is a cleaner window than a windy afternoon. Kids, a fountain, and backwash also empty the pool without a hole. Note those if you ran the test on a busy Saturday.
What a bucket test cannot do
It cannot tell shell from plumbing. It cannot find the fitting. It cannot replace dye, a pressure test, or a locator standing on the deck. A matching drop does not prove the pool is perfect — only that weather explained that stretch.
If the pool still loses water after a matching test, or the water bill jumped while the waterline looks stable, send the request anyway. Equipment and fill lines fail in ways a bucket on a step will not show.
What to write if you already ran one
How long you waited, whether the pump was off, and whether the pool dropped more than the bucket. City and finish help for travel and what a locator expects to see. You do not need a perfect test to request a water-loss locate.

Questions
How long should a bucket test run?
A quiet stretch of about a day is the usual home check. A still overnight is cleaner than a windy afternoon. If you cannot wait, request a locate and say you did not finish a test.
Does a matching drop mean there is no leak?
It means weather explained that window. Autofill, a feature, or a leak that only shows when the pump runs can still be in play. A locator confirms.
Do I have to run a bucket test before I request a visit?
No. It is useful context, not a requirement. Write what you already checked.
Is this the same as a pressure test?
No. A bucket test compares weather to pool drop. A pressure test isolates buried lines. Different tools, different questions.
