A Little Peace of Mind for Every Pool Owner.
You check your pool's chemicals. You clean its filters. You maintain its equipment. But do you know whether your pool is losing more water than it should?
Meet the Mini Bucket Test — a simple, reusable pool leak detector and evaporation tester that helps you distinguish normal water loss from a possible leak.
Don't wait until you suspect a problem. Keep one in your pool maintenance kit and check whenever you want greater confidence about your pool's water loss.
Why Every Pool Owner Should Have One
Pool ownership comes with regular maintenance expenses. Understanding water loss is another important part of protecting that investment.
Peace of Mind
Get a clearer picture of whether your pool's water loss is consistent with normal evaporation.
Check Before You Call
Make a more informed decision before spending money on professional leak investigation.
Simple to Use
No tape marks, rulers, or complicated calculations. Just match the water levels and compare.
Reusable and Practical
Keep it with your pool supplies for periodic checks or whenever water loss seems unusual.
Purpose-Built Design
A weighted base helps the clear tester remain upright on a submerged pool step.
Understand Your Pool
Learn whether a drop in water level may be caused by evaporation or something worth investigating.
Don't Wait Until You Suspect a Leak.
Heat, wind, humidity, and weather conditions all affect pool evaporation. A changing water level doesn't automatically mean something is wrong.
But when water loss exceeds normal evaporation, a leak may be responsible.
Mini Bucket Test gives you a straightforward first check, whether you're investigating unusual water loss or simply staying on top of routine pool maintenance.
Three Simple Steps. One Smarter Check.
You don't need specialized equipment or technical experience to get started.
Prepare Your Pool
Turn off automatic water-fill systems, waterfalls, fountains, and other water features that could interfere with the comparison.
Place & Fill
Set the tester upright on your first swim step, with its top above the pool water. Fill it until the water inside exactly matches the surrounding pool level.
Wait & Compare
After 24–48 hours, compare the water level inside the tester with the water level of your pool outside it.
What Do the Results Mean?
The Mini Bucket Test compares water loss inside the device with water loss in your swimming pool under similar environmental conditions.
Water Levels Still Match?
If both levels have dropped by approximately the same amount, normal evaporation is the more likely explanation.
Pool Water Lower Than the Tester?
If the water inside the tester is higher than the surrounding pool water, the pool may be losing additional water through a leak. Further investigation may be worthwhile.
Better Than the Traditional Bucket-and-Tape Method
The traditional bucket test can involve a household bucket, tape markings, and a makeshift setup.
The Mini Bucket Test offers a cleaner, purpose-built alternative. Its weighted bottom helps keep it stable, while its clear construction makes the water-level comparison easy to see.
There's no need to find a suitable bucket or mark water levels with tape. Just place, fill, wait, and compare.
Tips for the Most Reliable Results
- Turn off automatic pool-fill systems before starting.
- Turn off waterfalls, fountains, and other water features.
- Start with your pool pump running, keep it running throughout the test, and ensure it is still running when you compare the levels.
- Choose calm weather when possible. Heavy wind or rainfall can affect the comparison.
- Keep swimmers and pets out of the pool during testing.
- In windy conditions, keeping the water inside the tester closer to its top may help improve the comparison, provided the water cannot spill over.
- Ensure the tester remains upright and undisturbed throughout the test.
What If Your First Swim Step Is Too Deep?
The Mini Bucket Test is designed for most pools with a swim step. If your first step is too deep, you may wait until the pool level naturally drops to a suitable height or place the tester on a stable, level support to raise it into position.
Always make sure the tester is stable, partially submerged, and positioned with its top above the surrounding pool water.
After testing: Restore your automatic fill system and any water features you turned off.
A Smart Addition to Your Pool Maintenance Kit
You already monitor your pool's water chemistry, clean filters, and maintain equipment. Monitoring unusual water loss is another sensible part of pool care.
Mini Bucket Test is useful for backyard swimming pools and other compatible pools or spas with a suitable submerged step or stable testing position.
Use it periodically, when you notice unusual water loss, or when you simply want to confirm that evaporation is the likely explanation.
Know More. Worry Less. Enjoy Your Pool.
Not every drop in your pool's water level means there's a leak. And you shouldn't have to guess.
The original Mini Bucket Test gives you a simple, reusable way to check for unusual water loss and make more confident decisions about your pool.
A little preparation today can mean greater peace of mind tomorrow.
