Pool Leak Detection (Bucket Test) Gallon Loss
Convert your bucket test results (inches of water loss) into exact gallons per day to understand the severity of your pool leak.
Technical Comparison
| Daily Loss (Inches) | Severity | Action Required |
|---|---|---|
| Under 0.125" (1/8") | Negligible | Monitor closely |
| 0.25" (1/4") | Minor Leak | Check skimmer faceplate and light niche |
| 0.5" (1/2") | Major Leak | Call a professional diver/leak detector |
| 1" or more | Catastrophic | Shut off pump to test if plumbing vs shell |
Frequently Asked Questions
What is the Bucket Test?
You place a bucket filled with pool water on the stairs, aligned with the pool's water level. After 24 hours, if the pool water dropped 1/2 inch more than the water inside the bucket, you have a 1/2 inch leak (ignoring evaporation).
How many gallons of leak is considered 'normal'?
ZERO. A pool is a closed system. Any loss beyond the evaporation rate established by the bucket test indicates a physical structural compromise or plumbing crack.
