Pool Leak or Just Evaporation? El Monte Pool Bucket Test Calculator
El Monte pools lose water to San Gabriel Valley evaporation year-round. The bucket test is the most reliable way to separate a real pool leak from normal water loss before calling a technician.
How to Run the 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 marker.
- Run the pool pump on its normal schedule. Disable auto-fill. Wait 24 hours.
- Measure the drop inside the bucket and the drop outside the bucket. Enter both below.

Frequently Asked Questions
How do I know if my El Monte pool is leaking or just evaporating?
The bucket test is the standard answer. It runs the pool and a control bucket under the same conditions for 24 hours. If the pool drops more than the bucket, the difference is a leak. If both drop the same amount, you are seeing normal evaporation. Use the calculator above to quantify the difference. If a leak is confirmed, call (626) 898-6169 for professional pool leak detection.
How much water do San Gabriel Valley pools lose to evaporation per day?
In the San Gabriel Valley, typical evaporation rates run from about one-eighth of an inch per day in winter to more than a quarter inch per day in peak summer heat. The bucket in the test acts as your real-time evaporation measurement, so a precise seasonal figure is less important than the actual bucket reading on the day you run the test.
Does pool refilling raise my El Monte sewer bill?
No. El Monte sewer service (Los Angeles County Sanitation Districts) is a flat annual charge on the LA County property tax bill. It does not vary with water use. Pool refilling is outdoor water that drains to the yard or evaporates, not water that enters the sewer system, so a pool leak does not affect the sewer charge in any way. For leak detection and repair, call (626) 898-6169.
What is the pool bucket test?
The bucket test is a 24-hour controlled comparison between the pool and a control bucket of water placed on a pool step. The bucket matches the pool environment, so it evaporates at the same rate. If the pool loses more water than the bucket, the difference is a real leak rather than evaporation. The calculator above converts that measurement into gallons per day and an estimated monthly cost.
