Pump OFF loss (leak even when equipment is idle)
In Palm Beach Gardens, Florida Pool Leak Detection (BMW — Proof Tests + What to Check First), heat + sun can make evaporation look dramatic — so the *pattern* matters.
- Quick check: Mark the waterline at night, keep the pump off, and re-check in the morning.
- Quick check: Run a 24‑hour bucket test to compare pool drop vs bucket drop.
What it usually points to: A structure leak, a fitting at/near the waterline, or a line that can leak without pump pressure.
Next step: If the pool drops more than the bucket with the pump off, schedule detection so you’re not chasing ghosts.
Water loss mainly while the pump runs
Big day‑to‑day swings are common — an on/off check can save you hours of guessing.
- Quick check: Run the pump 2 hours, re-check the mark, then turn it off 2 hours and compare.
- Quick check: If you have a spa spillover / waterfall / cleaner line, run one feature at a time and watch for changes.
What it usually points to: Pressure‑side plumbing or a feature line that only leaks when pressurized.
Next step: Once you confirm “pump on = faster loss,” a pro can isolate the exact line without tearing up decking.
Stops at one exact spot
If you’re in Palm Beach Gardens, Florida Pool Leak Detection (BMW — Proof Tests + What to Check First), don’t trust “it feels like a leak” alone — confirm the stop level with one quick test.
- Quick check: Let the water fall until it stops and note the level (tile line, light, skimmer, returns, etc.).
- Quick check: Use dye near fittings at that exact level to see if it pulls in.
What it usually points to: A leak at or just below the stop level (skimmer throat, light niche, return fitting, tile line, or a crack).
Next step: The stop‑level clue is gold — share that level when you schedule so the pro can start in the right zone.
Wet spot / sinkhole / soggy deck area
In Palm Beach Gardens, Florida Pool Leak Detection (BMW — Proof Tests + What to Check First), water can travel under decking before it shows up — so the *location of the wet spot* isn’t always the leak.
- Quick check: Look for consistently wet soil, washed‑out sand, or settling near the wet area.
- Quick check: Note whether the wet spot changes when the pump runs vs when it’s off.
What it usually points to: An underground line leak or a leak under/near the deck that’s pushing water outward.
Next step: If you’re seeing soil movement or a sinkhole, schedule detection early to prevent bigger deck damage.
Bubbles at returns / pump struggling (air in the system)
If you see bubbles at returns or the pump basket never stays full, air leaks can be part of the story — sometimes paired with water loss.
- Quick check: Check the water level (too low can pull air through the skimmer) and inspect the skimmer weir.
- Quick check: With the pump running, lightly soap-test visible joints/valves at the pad for air pulling in.
What it usually points to: A suction‑side air leak (lid o‑ring, valve stem, union, skimmer line) that can mess with prime and performance.
Next step: If you can’t stabilize prime or bubbles won’t stop, a pro can isolate suction‑side issues quickly and safely.
Crack or grout-line leak suspicion
Hairline cracks and grout failures can be misleading. In Palm Beach Gardens, Florida Pool Leak Detection (BMW — Proof Tests + What to Check First), confirm the behavior before anyone proposes cutting or resurfacing.
- Quick check: Inspect the tile line, grout, and any visible crack for staining, flaking, or a “weeping” line.
- Quick check: Use dye along the suspected area with the pump off for a cleaner signal.
What it usually points to: A shell crack, tile/grout failure, or a fitting/collar leak near the surface.
Next step: Structural leaks are fixable — but you want the exact location confirmed before committing to a repair plan.
Not sure? 3 quick questions to narrow it down
Answering even one of these helps you land on the right troubleshooting lane in Palm Beach Gardens, Florida Pool Leak Detection (BMW — Proof Tests + What to Check First).
- Quick check: Does it drop faster with the pump ON? (Yes = pressure-side lane.)
- Quick check: Does it stop at a specific level? (Yes = that stop level is the clue.)
- Quick check: Is there a wet spot or air in the system? (Either one points to a specific lane.)
What it usually points to: A leak pattern is usually more reliable than a single symptom. Patterns repeat; “feelings” don’t.
Next step: If you can’t tell yet, do a bucket test and then re-check pump on/off — that usually reveals the lane.
Ready to schedule?
Common situation we hear: The equipment pad area stays damp, or you notice small drips near unions, valves, or the pump lid.
What to do first (fast, no-tools steps)
First: get one clean measurement. Mark the tile line with painter’s tape and take a photo. Check again ~24 hours later from the same angle. Write down the change in inches.
A single drop rate lets you compare tests. Without a number, everything feels like a guess—and guesses get expensive fast.
If you backwash, drain, overflow after rain, or have kids splashing all day, note it. Those events create “fake leak” signals that muddy the test window.
- Write down: inches lost in ~24 hours.
- Note: pump run time, rain, backwash, heavy swimming, autofill on/off.
- Look for: any repeat stop level.
Step 1: Prove leak vs evaporation
The bucket test is the quickest proof test you can do yourself. You’re comparing pool water loss to a bucket of water sitting in the same environment. If the pool drops more than the bucket, you’re seeing leak behavior.
Tip: place the bucket on a step so the bucket water is near pool water temperature. Mark both waterlines and wait about a day. That gives you a clean baseline you can trust.
If the bucket and pool drop the same amount, your primary issue is evaporation/weather. If the pool drops more, keep going—now you’re narrowing the source.
Step 2: Compare pump on vs pump off
Next, compare pump‑on vs pump‑off behavior. A leak that worsens when the system runs often points toward plumbing/equipment (pressure or suction side). A leak that continues similarly when the pump is off can point toward shell/waterline fittings or static leaks.
Run two windows if you can: one day with normal run time, another with the pump mostly off. You’re looking for a noticeable change in drop rate, not perfection.
This one comparison eliminates a ton of wrong repairs. It’s the shortcut most people skip—and it’s why they end up paying twice.
Step 3: Use the stop-level clue if you have it
If the pool repeatedly stops at the same height, treat that elevation like a clue. The leak is often at (or just below) that level—think skimmer throat, a fitting, a light niche, a crack at the waterline, or a feature that only gets wet above that point.
Mark the stop level with tape and measure from the coping. Then inspect everything that sits at that height. This is one of the most useful homeowner clues you can give a pro.
Equipment pad checks (the “easy win” zone)
Before you assume it’s underground, check the equipment pad while the system is running and again right after shutdown. Tiny drips at the pad add up over hours and days—especially if they only show under pressure changes.
Focus on: pump lid o‑ring/lid seating, unions, valve stems, filter drain plug, heater connections, chlorinator bodies, and any return-line fittings that sweat or drip.
- Pump lid + o‑ring seating
- Unions, valve stems, filter drain
- Heater/chlorinator bodies
- Any damp soil or steady drips
Suction-side clues (bubbles, air, losing prime)
If you’re seeing bubbles, air in returns, or losing prime, don’t ignore it. Suction-side issues can create weird symptoms and sometimes coincide with water loss. Start with the pump lid o-ring and suction unions, then review the common signs.
If you want the full symptom list and what it usually means, see the suction-side guide linked below.
Dye testing: when it helps (and when it doesn’t)
Dye testing is useful when you already have a suspect spot (skimmer throat, fitting, crack, light niche). It’s not great as a “scan the whole pool” tool. Use it like a confirm step, not a fishing expedition.
Turn the pump off, let the water settle, and apply dye near the suspect. If the dye gets pulled in, you’ve found a likely leak path.
Pressure testing (plumbing confirmation)
If your pattern points toward plumbing, pressure testing is the clean confirmation step before repairs. It tells you whether a line can hold pressure (and sometimes which zone is failing).
If you’re deciding between ‘dig and hope’ vs confirming first: confirm first. It’s almost always the cheaper path in the long run.
Cost: what moves the price (and what’s worth it)
Pricing varies depending on whether the leak is obvious or requires line isolation, multiple zones, or advanced locating. But the important part is value: good detection prevents the wrong repair.
If you want a sanity-check on what moves price (and what’s worth paying for), see the cost guide linked below.
Common mistakes that waste time and money
- Ignoring small drips at the equipment pad because they ‘look minor.’
- Assuming evaporation without doing the bucket test baseline.
- Ignoring small drips at the equipment pad because they ‘look minor.’
- Assuming evaporation without doing the bucket test baseline.
- Ignoring small drips at the equipment pad because they ‘look minor.’
If you’re not sure where to start, begin with bucket test + pump on vs pump off. Those two steps eliminate most guesswork.
Palm Beach Gardens pool leak FAQs
What info helps a pro diagnose faster?
Drop rate in inches/24h, pump‑on vs pump‑off behavior, any stop level, and any wet spots or pad drips.
Why is loss worse when the pump runs?
That often suggests plumbing/equipment involvement. Confirm with pump‑on vs pump‑off tracking.
Should I repair before confirming?
Confirm first whenever possible—pressure testing and pattern checks often prevent the wrong repair.
Is dye testing worth doing?
Yes, but only when you already have a specific suspect spot. Dye is a confirm tool, not a wide-area search.
Should I shut off the autofill while testing?
Yes—turn it off for the test window. Autofill masks the true drop rate and makes patterns harder to see.
Could a small pad drip cause a big drop?
Yes. Small drips add up over hours and days, especially during pump run time.
Why does the pool stop at the same level?
A repeat stop level is a strong clue that the leak is near that elevation. Inspect features at that height.
How much water loss is normal?
Normal varies with weather, but the bucket test gives you your baseline. If the pool drops more than the bucket, treat it as leak behavior.
