Pool Leak Detection in Jacksonville and St. Augustine, FL
The Hidden Dangers of an Undetected Pool Leak
Structural Instability
Water escaping beneath the pool deck or shell can wash away supporting soil, leading to sinkholes, shifting concrete, and major structural cracks.Equipment Strain
To keep your pool filled, automatic levelers run constantly. This introduces cold, untreated water, forcing your pool heater and filtration systems to work overtime, leading to premature equipment failure.Chemical Imbalances
Constant dilution with fresh water makes it incredibly difficult to maintain proper chemical balance, inviting algal blooms and unsanitary swimming conditions.High Utility Bills
Thousands of gallons of lost water translates directly into spiked monthly water and sewer bills.How to Determine If You Need Pool Leak Detection
- Bring the pool water to its normal operating level.
- Fill a 5-gallon bucket with pool water to about five inches from the top.
- Place the bucket on the first or second step of the pool.
- Mark the water level inside the bucket and the pool's water level outside the bucket.
- Wait 24 to 48 hours, then compare the two levels. If the pool water level has dropped significantly more than the bucket's water level, you have a leak and require professional leak detection for pools.
Our Advanced Swimming Pool Leak Detection Process
1. Pressure Testing Plumbing Lines
Many pool leaks occur within the underground plumbing lines. We seal the lines and apply consistent pressure to monitor for any drops. If a line cannot hold pressure, we know exactly which plumbing run is compromised.
2. Electronic and Acoustic Listening Devices
Using highly sensitive geophones and underground microphones, our technicians can hear the distinct sound of water escaping from pipes beneath feet of concrete or soil. This acoustic technology allows us to pinpoint the exact location of a pipe break before we begin excavation.
3. Underwater Dye Testing
For leaks suspected within the pool shell, such as around light fixtures, return jets, main drains, or structural cracks, we perform precise dye testing. By releasing a specialized, heavy dye near suspected areas, we can visually track if the dye is sucked into a crack or seam, confirming a structural leak.
