Pool Leak or Just Evaporation? Round Rock Pool Bucket Test Calculator
Round Rock pools lose water all season to Central Texas heat and evaporation. The bucket test is the most reliable way to separate a real leak from normal evaporation before calling a technician. With Round Rock tiered water pricing, a leaking pool that pushes monthly usage into Tier 3 or Tier 4 can add up significantly.
How to run the pool bucket test
- Fill a 5-gallon bucket with pool water to about 1 inch from the top.
- Place it 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 how much the level dropped inside the bucket and outside. Enter both below.

Frequently Asked Questions
How do I know if my Round Rock pool is leaking or just evaporating?
The bucket test is the standard method. A bucket placed on the pool step loses water to evaporation at the same rate as the pool surface. If the pool drops more than the bucket over 24 hours, the difference is a leak. If both drop equally, evaporation is the cause.
How much water do Central Texas pools lose to evaporation per day?
In summer heat, a Round Rock pool can lose a quarter inch or more per day to evaporation. A 20-by-40-foot pool losing 0.25 inches evaporates about 124 gallons per day. In the bucket test, the bucket will show roughly the same loss if no leak is present.
What is the pool bucket test?
The bucket test is a simple 24-hour comparison. You fill a bucket with pool water, set it on the pool step, mark the water levels inside and outside the bucket, run the pump normally, and compare the drops after 24 hours. A difference between pool drop and bucket drop indicates a leak.
How much does it cost to refill a pool in Round Rock TX?
A 20-by-40-foot pool holds about 24,000 gallons. Filling from empty at Round Rock rates crosses Tier 3 and Tier 4, costing roughly $100 to $130 for water alone depending on existing usage. Ongoing refilling from a leak at 50 to 100 gallons per day can add $20 to $50 per month on top of normal water bills.
