What Are the Most Common Places for a Pool Leak?

The most common pool leak locations are the skimmer, return lines, pool lights, and plumbing connections. The skimmer is often the number one culprit, with leaks developing where the skimmer meets the pool wall or at cracks in the skimmer body itself. Return lines and pool lights are also prone to leaking, especially where pipes or conduits connect to the pool shell.

Cracks in the pool wall, pool liner, or pool shell can also cause leaks, as can issues with underground plumbing or pool equipment. Regular inspection of these areas is key to catching leaks early and avoiding costly repairs.

Why Is the Skimmer the Most Common Pool Leak Location?

The skimmer is the most common pool leak spot because it’s where plastic meets concrete or gunite, creating a “cold joint” that can separate over time due to soil movement, freeze/thaw cycles, or poor installation. Cracks can form at the mouth, body, or pipe connections of the skimmer, letting water escape.

If you notice water loss or wet spots near the skimmer, a dye test can help confirm if this is the source. Applying pool putty to small cracks is a common repair, but persistent skimmer leaks may need professional attention.

How Do Pool Lights Cause Leaks?

Pool lights are another frequent source of leaks, especially at the conduit where the light niche connects to the pool wall. If the conduit or seal fails, water can travel through the conduit and escape the pool.

These leaks are tricky because they’re often hidden behind the pool wall. Using dye or specialized leak detection equipment helps pinpoint the exact location without unnecessary digging or damage.

Can Return Lines and Pool Plumbing Leak?

Return lines and pool plumbing are common leak points, especially if pipes shift or settle over time. Leaks often occur where pipes connect to the pool wall or fittings, or in underground plumbing due to corrosion, ground movement, or aging PVC pipe.

If you see wet spots around the pool deck or notice a drop in water pressure, your plumbing system may be leaking. Pressure testing and electronic listening devices, like those from Leaktronics, can help locate these hidden leaks.

What About Cracks in the Pool Shell or Liner?

Cracks in the pool shell, plaster, or liner are a classic cause of pool leaks. Concrete pools can develop cracks from ground movement or impact, while vinyl liners are prone to tears from sharp objects or age.

Inspect your pool surface regularly for visible cracks or soft spots. A dye test can confirm if a crack is actively leaking. Small cracks can often be patched, but larger structural issues require professional pool repair.

How Do You Know If Your Pool Is Leaking?

Common signs of a pool leak include:

• Unexplained water loss (more than 1/4 inch per day)
• Wet or mushy spots around the pool
• Cracks or loose tiles
• Higher water bills
• Air in the pool pump or bubbles from returns

The bucket test is a reliable way to tell if you’re losing water to evaporation or a leak. Place a bucket filled with pool water on a pool step, mark the levels, and compare after 24 hours. If the pool water drops more than the bucket, you likely have a leak.
