Swimming Pool Water Loss Calculator
Estimate the volume represented by a rectangular pool's measured water-level drop over 24 hours. This total includes evaporation and any other losses; use the bucket test below to compare pool and bucket drops under similar conditions.
Enter Pool Measurements
Enter rectangular pool dimensions and a 24-hour water-level drop to estimate total volume lost.
Midland Water Meter Leak Test Guide & Analyzer
Record the meter increase over a timed period with normal water use stopped. The calculator converts that reading to average flow and constant-flow projections; it cannot locate a leak or establish pipe condition.
Shut Off All Water
Ensure all faucets, ice makers, washing machines, and irrigation valves are tightly turned off.
Locate Meter Box
Usually near the front sidewalk or curb inside a cast iron or plastic ground vault.
Check Flow Dial
Look for the low-flow indicator (small red triangle, blue star, or spinning digital decimal).
Wait 60 Minutes
Record numbers at the start and end of a 1-to-2 hour test period with zero water usage.
For meter checks and possible sources of increased use, see the City of Midland leak detection guide.
Enter Meter Test Readings
Enter meter readings and test duration to estimate flow. Add your own bill rate if you want a water-charge estimate.
Evaporation Bucket Test Calculator
A bucket test compares water loss under similar weather conditions. Place a partially filled bucket on a pool step and measure the bucket and pool drops over the same 24 hours. A difference can guide further testing; it does not identify a failed pipe.
How to Execute the 24-Hour Bucket Test in Midland:
- Choose 24 hours without rain or strong wind. Keep swimmers out and stop filtration, pool cleaners and automatic refilling for the test.
- Set a 2.5-to-5-gallon bucket on a pool step with at least two-thirds underwater. Fill it nearly to the rim, a little above the pool waterline.
- Mark the starting waterline inside the bucket and the starting level of the still pool water separately.
- Leave both undisturbed for 24 hours without adding water.
- Measure each level again and enter the drop in inches for that same 24-hour period.
Method: EPA WaterSense pool guide, page 8.
Enter Bucket Test Measurements
Enter both drops from the same 24-hour test to estimate any pool loss above the bucket comparison.
How We Confirm What Your Calculator Indicates
If the calculations suggest unusual loss, meter checks and a qualified inspection can help identify the source. A calculator cannot locate a leak by itself.
Sub-Surface Yard & Main Line Listening
Pinpointing high-frequency vibration frequencies generated by pressurised water escaping through PVC or copper fissures buried 3–5 feet beneath West Texas caliche clay.
Concrete Foundation Heat Signature Mapping
Detecting hot water slab fractures through tile, hardwood, and laminate without breaking concrete. High-resolution FLIR cameras isolate the subsurface rupture within minutes.
