Pool Leak or Just Evaporation? La Puente Pool Bucket Test Calculator
La Puente pools lose water to evaporation year-round in the San Gabriel Valley climate. The bucket test is the most reliable way to separate a real leak from normal water loss before calling a pool leak detection technician. Run the test first, then enter your measurements below to get a verdict and the estimated cost at real LPVCWD water rates.

How to run the 24-hour bucket test
- Fill a 5-gallon bucket with pool water to about 1 inch from the top.
- Place the bucket on the first or second pool step so the water level inside matches the pool water level outside.
- Mark the inside bucket level and the outside pool level with tape or a waterproof marker.
- Run the pool pump on its normal schedule. Disable auto-fill. Do not add water. Wait 24 hours.
- Measure how much the level dropped inside the bucket and outside in the pool, and enter both numbers below.

What the pump-on and pump-off comparison tells you
After a positive result, the most useful follow-up is a second 24-hour test with the pump completely off. If the pool loses significantly more water with the pump running than it does overnight with the pump off, the leak is on the pressure side of the plumbing, in the lines from the pump to the pool returns. If the loss is similar with the pump on or off, the leak is in the shell itself, the skimmer, or the suction fittings. Sharing that comparison with a technician from inground pool leak detection typically cuts the diagnosis time in half.

Pool leak and bucket test questions for La Puente
How do I know if my La Puente pool is leaking or just evaporating?
The bucket test separates the two causes reliably. Place a bucket of pool water on the first step so the water level inside the bucket matches the pool level outside it. Mark both levels, run the pump on its normal schedule, and check again after 24 hours. If both drop the same amount, the loss is evaporation. If the pool drops more than the bucket, the difference is a leak.
How much water do San Gabriel Valley pools lose to evaporation per day?
In La Puente and the broader San Gabriel Valley, pools typically lose between a quarter inch and a third of an inch per day to evaporation during summer, less in cooler months. Wind, low humidity, and direct sun all increase the rate. The bucket test accounts for all of these conditions automatically, because the bucket and the pool are exposed to the same weather at the same time.
Does pool refilling raise my sewer bill in La Puente?
No. La Puente sewer is billed by the Los Angeles County Sanitation Districts as a flat annual fee on the property tax bill, not as a volumetric charge on the water bill. Pool water drains to the yard rather than the sanitary sewer, so neither pool evaporation, pool leaks, nor pool refilling increases the sewer charge.
What is the pool bucket test?
The pool bucket test is a simple 24-hour measurement that compares the natural evaporation rate (measured by the bucket) against the total water lost by the pool. Fill a 5-gallon bucket with pool water, set it on the first step so the inside water level matches the pool level, mark both levels, run the pump normally, and measure both drops after 24 hours. The pool bucket test calculator on this page converts the difference into gallons lost per day and the estimated water cost at La Puente Valley Water District rates.
