Pool Leaks Start Small but Get Expensive Fast
A small pool leak might not seem urgent — maybe you are adding an extra inch of water each week and chalking it up to Florida evaporation. But undetected leaks waste thousands of gallons of water, erode the ground around your pool, damage your deck, and can undermine your pool's structural integrity. In Tampa Bay's sandy soil, the consequences of a neglected leak escalate quickly.
Why This Matters in Tampa Bay
Florida's sandy, porous soil means water from a pool leak travels fast and far, potentially washing away the fill material supporting your pool shell and deck. Combined with our high water table, a leak can create sinkholes, crack decking, and cause settlement damage that costs tens of thousands to repair. Early detection is the most cost-effective strategy.
Signs You May Have a Pool Leak
Excessive Water Loss
Pools in Tampa Bay lose about a quarter inch per day to evaporation during summer. If you are losing more than that consistently, a leak is likely. Perform a bucket test: fill a bucket to pool water level, set it on the step, and compare levels after 24 hours. If the pool drops more than the bucket, you have a leak.
Constantly Running Autofill
If your autofill valve runs frequently or your water bill has increased without explanation, suspect a leak before assuming increased evaporation.

Cracks in the Pool Deck
Water escaping from plumbing under the deck can erode soil and cause sections to settle or crack. New or widening cracks near the pool edge are a red flag.
Wet or Soft Spots in the Yard
Unexplained soggy areas near the pool, especially when it has not rained, suggest an underground plumbing leak.
Air Bubbles in the Return Lines
Air entering the system through a suction-side leak can cause visible bubbles at return jets. This often accompanies pump priming issues.
Increased Chemical Consumption
A leaking pool constantly loses treated water and gains untreated fill water, requiring more chemicals to maintain proper balance.
Common Leak Locations
- Skimmer connection: The joint between the skimmer body and the pool wall is a frequent leak point
- Return fittings: Fittings sealed to the pool shell can loosen over time
- Main drain: Underground plumbing connections at the main drain are prone to failure
- Light niche: The conduit behind your pool light can develop leaks
- Shell cracks: Structural cracks in plaster, fiberglass, or concrete allow water to seep out
When to Call a Local Pool Pro
If your bucket test confirms a leak, do not attempt to excavate or repair plumbing yourself. A professional leak detection company uses pressure testing, electronic listening equipment, and dye testing to pinpoint the exact location without unnecessary digging. Once you have a detection report, we handle the repair. We do not perform leak detection testing, but we can repair leaks once identified or provide a second opinion on findings. Our suspected pool leak guide works from detection reports, prior inspections, or visible symptoms to fix structural, plumbing, and equipment leaks across Tampa Bay.
Significant leaks often accompany aging equipment. If your pool is over 15 years old and showing leak symptoms alongside worn equipment, a pool renovation may address multiple issues at once. For equipment-related leaks at pumps or filters, visit our equipment repair page.
Act Early, Save Big
The average cost of leak detection and a simple repair is $300 to $800. The average cost of repairing structural damage from a neglected leak runs $5,000 to $15,000 or more. Early detection is always the better investment. Explore our replacement parts for common fittings and seals, or contact us and we can talk through what the pool is doing.
