South Florida pools lose water to evaporation every day, and in the heat of summer that loss can look a lot like a leak. Before paying for detection, it's worth confirming whether your water loss is normal or something more. The bucket test is a simple, widely used method that compares how much water the pool loses to how much a sealed container loses to evaporation alone. It's the first step we recommend, and we can guide you through it or run it for you.
What a bucket test is
A bucket test measures whether your pool is losing more water than evaporation alone can explain. You fill a bucket with pool water, set it on the pool steps so the water level inside matches the pool, and mark both levels. After a day or two, you compare how much each dropped. If the pool lost noticeably more than the bucket, a leak is likely. If they dropped about the same, evaporation is probably the cause.
Why it matters in South Florida
Cooper City's heat, sun, and wind drive fast evaporation — a pool can lose up to about a quarter inch of water a day on a hot, breezy day with no leak at all. Add in splash-out from swimming and backwashing, and it's easy to mistake normal loss for a leak. The bucket test cuts through that guesswork by giving evaporation its own reference. It also helps catch the opposite problem: a slow leak that's been hiding behind what looked like normal evaporation.
Signs you should run a bucket test
- Your pool loses more than about a quarter inch a day with no obvious cause
- The auto-fill runs constantly to keep up with water loss
- Your water bill has climbed and you can't explain it
- You're not sure whether the recent heat or the pool is to blame
How the test works
The test is straightforward and uses items you likely already have:
- Fill a bucket with pool water and set it on the pool steps, weighted so it stays put
- Adjust the water in the bucket so it matches the pool's water level exactly
- Mark the water level on the inside of the bucket and on the pool wall or tile
- Turn off the auto-fill and let the pool sit for 24 to 48 hours
- Compare the two drops — if the pool dropped more than the bucket, a leak is likely
Run the test with the pump off for one round and on for another if you can. A difference between the two can point to a plumbing leak versus a shell leak.
What we do if the test points to a leak
If the bucket test shows the pool is losing more than evaporation, we move on to full leak detection — visual inspection, pressure testing, and dye testing to find exactly where the water is going. If the test shows the loss is just evaporation, you've avoided an unnecessary service call and you'll know what's normal for your pool going forward.
When to call us
If you've run a bucket test and the pool lost more than the bucket, reach out and we'll schedule detection. If you'd rather not run it yourself, we can perform the test and the follow-up detection in one visit. Either way, you'll get a clear answer about whether your pool is actually leaking.
