Detection finds the source. Repair cost depends on what’s leaking and how accessible it is.

• Pool crack repair (structural leak): $2,500 – $3,500
• Through the deck plumbing leak repair: $1,400 – $1,850+
• Skimmer replacement: $1,800+
• Difficult excavation situations, repairing 3’ below ground level, and repairs in the spa/pool wall can be higher depending on scope.

If you already know precisely where the leak is, you may be able to schedule professional pool leak repair with Leak Wizard without a full diagnostic visit.

Several factors influence how much testing is required to locate a swimming pool leak.

1. Where the Leak Is Located

Some leaks are easy to identify, such as a leaking skimmer or visible crack. Others may require specialized leak detection equipment and additional testing.

Pool leaks can occur in:

• Suction lines
• Return lines
• Main drain lines
• Spa therapy jet lines
• Skimmers
• Pool lights
• Cracked wall fittings
• Main drains
• Pool or spa shell cracks

2. Pool Type and Surface

Leak Wizard provides leak detection services for:

• Gunite and concrete pools
• Fiberglass pools
• Infinity pools
• Commercial pools

Different pool types and designs may require different testing methods to identify the source of a leak.

3. Access to Plumbing and Equipment

If pool equipment is in a tight space, plumbing lines are difficult to isolate, or the leak is beneath the pool decking, it may require additional time and testing.

4. Leak Severity and How Long It's Been Leaking

Waiting to address a pool leak can lead to:

• Washed-out soil
• Deck settling
• Increased crack movement
• Higher repair scope and cost

5. Multiple Leaks (Yes, It Happens)

Sometimes more than one leak exists, such as a crack and damaged fitting or a skimmer and plumbing leak. This can increase testing time.

If testing confirms the issue is in your plumbing lines, our team can handle underground pool plumbing repair in Tampa and restore proper circulation.

A lot of pool owners waste money by guessing and:

• Replacing pumps
• Swapping filters
• Sealing random fittings
• Patching without confirming the source
• Wait and see

Leak detection saves money because you repair the right thing the first time.

If your pool is losing water, the best path is:
1. Confirm it’s not normal evaporation (perform proper bucket test)
2. Identify whether it’s a structural leak or plumbing leak
3. Call a pool leak detection specialist

4. Perform recommended repairs.

BUCKET TEST (PUMP OFF – 24 HOURS)

1) Set your pool water level

Fill your pool to its normal operating level (about halfway up the skimmer opening).

2) Prepare the bucket

Use a clean 5-gallon bucket and fill it with pool water to about 3 inches from the top.

3) Place the bucket on a step or sun shelf

• Set the bucket on the top step (or a sun shelf) so it won’t tip.
• The pool water outside the bucket should cover the bucket by about 4–6 inches.

4) Mark both water levels

Use tape or a waterproof marker to mark:

• The water level inside the bucket
• The pool water level on the outside the bucket

5) Keep the pool undisturbed

Avoid swimming, pets, and splashing during the test. Excessive splash-out can skew results.

6) Wait 24 hours

Allow the pool to sit undisturbed for a full 24 hours.

7) Check results

Compare the two marks:

• If the outside pool level drops more than inside the bucket → your pool likely has a leak
• If both levels drop evenly → the water loss is due to normal evaporation

Even if it’s a leak, you still need to locate it—because repairs depend on the source.

BUCKET TEST (PUMP ON – 24 HOURS)

(Only if Pump OFF shows no difference)

If there is no difference between the bucket and pool after the pump-off test, continue the test again with your system operating normally. This helps determine if there’s a leak in the spa or plumbing that only shows while the pool is running.

1) Turn the system back on

Let the pool run its normal schedule for the next 24 hours.

2) After 24 hours, check the marks again

When the equipment is off, compare the bucket mark to the pool mark:

• If the pool water is further off the mark than the bucket → you likely have a leak
• This often points to a plumbing line leak, spa, or fountain.

Call if you notice:

• Pool water level dropping consistently more than ¼” per day
• Wet spot near the pool or soft ground near deck
• Pump losing prime or pulling air
• Bubbles from returns
• High water bill with no other cause
• Visible cracks or cracks that are worsening

Leak Wizard may use a combination of:
• visual inspection of common leak points
• dye testing around fittings (skimmer, returns, light niche)
• line isolation checks (as needed)
• pressure testing for plumbing lines (if the leak points to underground lines)
