The Pool Bucket Test: Leak or Evaporation, Settled in a Day
Every June, East La Puente’s backyards restart the same argument: the pool is losing water, and someone blames the heat while someone else blames a leak. Both are plausible, inland summers here run 88 to 93 degrees with real evaporation, and neither deserves a repair budget without evidence. The bucket supplies the evidence for the cost of tap water. The follow-up, if the bucket convicts, is (626) 898-6169.
Why the test works
Evaporation is weather acting on water surfaces, and it acts on all of them equally: a bucket of pool water sitting in the pool experiences the same sun, wind, and humidity as the pool around it. So mark both levels, wait a day, and compare. If both dropped the same distance, the weather took the water and the plumbing is innocent. If the pool outdropped the bucket, the difference is leaving through a hole, and the argument is over.
The elegance is that no instrument is calibrated finer than a level line, and no expert opinion outranks two pencil marks a day apart.
Running it properly, because sloppy tests lie
Fill a bucket with pool water and set it on a step so it shares the pool’s temperature, weighting it with a rock or brick against floating. Fill until the bucket’s water sits an inch or two below its rim, then mark the water level inside the bucket and the pool level outside it, tape or a grease pencil on the tile line. Run twenty-four hours with the pump on its normal schedule, then read both marks in the same light. Repeat a second day with the pump off entirely.
That second day is the bonus diagnostic: loss that appears only with the pump running points at the pressurized plumbing, while pump-off loss points at the shell and its fittings, and arriving with that split already known shortens the professional search meaningfully.
Reading the verdict, and what each one costs
A tie between bucket and pool ends the story pleasantly: you have summer, not a leak, and the water bill’s rise is the season’s. A pool outdropping its bucket by a noticeable margin has a genuine leak, and the professional sequence, dye at the fittings, pressure isolation on the loops, listening along the guilty run, takes it from there; the pool page walks the whole method, and the inground page covers the structural suspects.
Either verdict beats a summer of blind top-ups on metered water, which is the one strategy guaranteed to cost more than the answer.
