A pool that keeps needing water is one of the more frustrating problems to diagnose, because the water level can drop for reasons that have nothing to do with a leak. Before assuming the worst, it helps to understand the difference between normal evaporation and an actual leak, and what to check in between.
Evaporation or a Real Leak?
Florida’s heat and wind can evaporate a surprising amount of water, especially in summer. A simple way to check: mark the water level with tape, then place a bucket filled to the same level on a pool step. Wait 24 hours and compare. If the pool has dropped noticeably more than the bucket, it is likely a leak rather than evaporation.
Signs That Point to a Leak
- Water level drops faster than expected, even after refilling
- Damp spots on the ground near equipment or plumbing lines
- Air bubbles coming from the return jets
- Chemical levels seem off even shortly after balancing
- Cracks or staining along the shell or tile line
- Unexplained changes in pump pressure
Where Leaks Commonly Hide
Pool shell and fittings
Skimmers, return fittings, the light niche, and the main drain area are common leak points because they penetrate the pool shell.
Equipment connections
Pumps, filters, heaters, and salt systems all have seals and unions that can develop leaks over time. A wet equipment pad is often the first sign.
Underground plumbing
These leaks are the hardest to spot because there is often no visible sign at the surface, especially in early stages.
When to Call a Professional
If the bucket test points to a real leak, or if you are seeing damp spots, staining, or unexplained pressure changes, it is time for a proper inspection. Supreme Pool Services provides in-house pool leak detection, working through the pool shell, equipment connections, and plumbing methodically to find the actual source instead of guessing.
What It Costs
Leak detection service typically runs in the $200–$500 range, depending on how extensive the inspection needs to be. Once the source is found, repair costs vary widely depending on whether the fix involves a fitting, a piece of equipment, or underground plumbing — we always provide a clear explanation and a free estimate before any repair work begins. For general pricing across our other services, see the pool service cost guide for Palm Beach County.
Common Questions
How much water loss is normal from evaporation?
In Florida’s summer heat, a quarter to half an inch a day is common. Anything noticeably beyond that is worth investigating further.
Can a leak affect my pool chemistry?
Yes. Leaking water gets replaced with fresh water, which dilutes your chemical balance and can make it feel like your chemistry will not hold steady no matter how often you adjust it.
Do I need to drain my pool to find a leak?
Not usually. Most leak detection starts with visual inspection and equipment checks before any more invasive steps are considered.
