Pool Leak Detection in Tucson
Tucson pools lose a lot of water to evaporation in summer, so a dropping water level doesn't automatically mean a leak. If you're refilling more than seems right, start with a bucket test, then call a leak specialist if the numbers don't add up.
Symptoms
- Water level drops faster than a bucket of pool water beside it
- Autofill running constantly or the water bill climbing
- Wet spots, soft soil or sinkholes near the pool or equipment
- Cracks in plaster or tile, or loose tile at the waterline
- Air in the pump basket, or water dropping only when the pump runs (or only when it's off)

What the contractor checks
- Bucket test confirmation
- Dye testing at fittings, returns, skimmer throats and light niches
- Pressure testing of suction and return lines
- Electronic listening to pinpoint underground leaks
- Equipment-pad leaks at the pump, filter, heater and valves
Where leaks hide
| Location | Clues |
|---|---|
| Plumbing lines | Loss mostly while the pump runs (return side) or while it's off (suction side), plus wet ground along the line |
| Shell | Visible cracks, steady loss whether the pump is on or off |
| Light niche | Level stops dropping around the light |
| Skimmer | Level stops mid-skimmer; separation between the skimmer and the deck |
| Equipment pad | Drips or puddles at the pump, filter or heater |
Repair or replace?
Some leaks, like a skimmer throat or a light-niche conduit, can often be sealed. Underground plumbing leaks may need excavation to make a spot repair. Shell cracks may need patching or a larger resurfacing discussion. Ask the contractor to show you where the leak is and to explain the options.

FAQ
Can leaks be found without draining?
Usually, yes. Most leak detection is done with the pool full.
Does the pool drop more with the pump on or off?
Track it both ways, and tell the contractor what you find, since it narrows down whether the leak is on the pressure side or the suction side. Our bucket test guide shows how.
Is a leak urgent?
It wastes water and can wash out soil under the deck or equipment. Get it checked rather than refilling indefinitely.
