Pool needs to be Clear and Clean, Not Green
In most cases, it is recommended to have the pool vacuumed spotless prior to your detection. Leaks as a large 1″ in diameter have been missed until the dirt covering them was vacuumed or brushed away. Make sure the water is clean and not green. If it is green, the water could contain molds, fungus, larvae, and other contaminants that could make you sick, besides making it almost impossible to test.
Have the following information ready when you call to schedule your professional pool leak detection.
- Is it a pool only or does it also have a spa?
- Is the pool equipment above or below ground?
- How many pumps?
- Is the pool constructed of fiberglass, gunite, marcite, or vinyl?
- How many skimmers?
- Does it leak more with the filter on or with it off?
- How much water does it lose a 24 hour period?
If your pool or spa is losing a half an inch a day, it could be evaporation, or it could be a leak. A quarter inch per day is most likely to be evaporation. The evaporation rate in your area will depend on humidity, sunlight intensity, barometric pressure, wind, as well as the level of activity in the pool or spa.
Preparing for a service call
When calling for service, you may be asked how many inches of water your pool or spa is losing per day. If you don’t know how much water your pool or spa is losing per day, you may be asked to perform the bucket test to determine if your pool is leaking or losing water to evaporation.
