Step-by-Step Instructions for a Pool Bucket Test
-
Find a 5-Gallon Bucket
Start with a clean, watertight five-gallon bucket that is suitable for holding water. Do not use a container with cracks, holes, or chemical residue.
-
Fill the bucket to about an inch from the top
Fill the bucket to about an inch from the top. You want it filled as high as possible to replicate the condition of the pool.
-
Put the bucket on the first or second step inside your pool
Set the bucket securely on the first or second pool step. Keep the rim above the pool water and make sure the bucket cannot tip over or float away. A clean weight can help stabilize it.
If the pool has no suitable step, ask your pool professional about a safe alternative. A bucket on a deck can warm differently from the pool, so its evaporation may not be a close comparison.
-
Mark where the water level is on the inside of the bucket
Mark where the water level is on the inside of the bucket. This can be with tape or a permanent marker
-
Mark where the pool water level is on the outside of the bucket
Mark where the pool water level is on the outside of the bucket. Again, you can use a piece of tape or a marker.
-
Turn off your autofill
It is very important to make sure that any autofill devices are turned off or removed from the pool.
-
Wait 24 Hours
Wait 24 hours during a dry-weather period. Do not swim, add water, backwash, or allow pets to drink from or disturb the bucket. Record the pump and water-feature settings so you can interpret the comparison.
-
Use a ruler to measure how far the water has dropped in the bucket
It is very important to use a ruler because accuracy is necessary for your peace of mind and for the leak detection specialists. Measure the distance between the mark you made and where the bucket water level is now.
-
Use the ruler to measure how far the pool water has dropped on the outside of the bucket.
Measure the distance between the mark you made the day before and where the water level is now.
-
Compare the two measurements
If the pool and bucket lose about the same amount, evaporation may explain the loss during this test. Repeat the comparison if conditions change or an intermittent leak is still suspected.
If the pool loses more water than the bucket after other water losses are accounted for, a leak is possible and further investigation is appropriate.
Supply:
- 5-Gallon Bucket
- Ruler
- Tape
- Pen
- Brick
Benefits of doing this test
