Palm Beach Gardens Pool Leak Detection: Proof Tests and What to Check First

Start With One Clean Water-Loss Measurement

Before you blame a crack, skimmer, return line, or equipment fitting, get one clean number. Mark the waterline on
the tile, skimmer face, or a fixed photo reference. Check it again about 24 hours later from the same angle.

That number matters because “the pool looks low” does not tell you enough. Half an inch in windy weather is a
different conversation than an inch or more every day, especially if the pattern repeats when the weather changes.

• Write down the inches lost in about 24 hours.
• Note whether the pump was running normally, off, or on a changed schedule.
• Record rain, backwashing, overflow, heavy swimming, heater use, and autofill behavior.
• Take a photo of the starting mark and the ending mark.

Separate Evaporation From Leak Behavior

Palm Beach Gardens pools can lose water from heat, wind, sun exposure, heaters, water features, and splash-out.
The bucket test gives you a cleaner comparison because the bucket and pool sit through the same weather window.

If the pool and bucket drop about the same amount, evaporation is more likely. If the pool drops more than the
bucket, keep investigating because the pool is losing water beyond normal evaporation.

Notice Whether the Leak Changes With Pump Runtime

A pool that loses more water while the pump is running may have a pressure-side issue: return plumbing, filter
connections, heater unions, check valves, cleaner lines, spa spillovers, or water-feature plumbing.

A pool that keeps dropping even when the pump is off points the search in a different direction. That can involve
the shell, skimmer throat, light niche, tile line, return fittings, or a crack at the waterline.

• Compare one period with normal pump runtime and one period with the pump off if safe.
• Watch the equipment pad while the system is under pressure.
• Run spillovers, waterfalls, and cleaner lines one at a time if they may be involved.
• Save the drop-rate numbers instead of relying on memory.

Check the Equipment Pad Before Assuming It Is Underground

A damp equipment pad is one of the easiest clues to overlook. Small drips around unions, valve stems, filter
drains, heater connections, pump lids, or chlorinators can add up over a full pump cycle.

Look at the pad while the pump is running, then again after shutdown. Some leaks only appear under pressure;
others show up as the system relaxes.

Use a Stop Level as a Location Clue

If the pool drops and then stops at the same height, do not ignore that. The waterline is telling you where to
look first. The leak is often at or just below the point where the water stops falling.

Compare that height to the skimmer throat, tile line, light niche, return fittings, steps, benches, and visible
cracks. Take a photo before refilling if the water level is safe.

• Skimmer-level stop may point toward the skimmer throat or faceplate area.
• Light-level stop may involve the light niche or conduit.
• Return-level stop may involve a fitting or nearby line.
• Tile-line stop may involve grout, shell movement, or a waterline crack.

Do Not Ignore Air, Bubbles, or Losing Prime

Bubbles at the returns, a pump basket that will not stay full, or a pump that keeps losing prime usually points
toward air entering on the suction side. That does not automatically mean the pool is leaking underground, but it
is still part of the diagnostic picture.

Start with visible items: water level, skimmer weir, pump lid o-ring, suction valves, unions, and drain plugs.
If air symptoms appear along with confirmed water loss, the system may need more careful isolation.

When Dye Testing or Pressure Testing Makes Sense

Dye testing works best when you already have a suspect spot: a skimmer throat, return fitting, light niche, step
crack, tile edge, or visible shell crack. It is not the best tool for randomly searching the entire pool.

Pressure testing is different. It is used when the pattern points toward plumbing and you need to know whether a
line holds pressure before anyone cuts, digs, or guesses at a repair.
