North Texas Pool Leak Detection and Repair

Written by Steven Shipler, Texas Licensed Master Plumber and Responsible Master Plumber, Texas License #45825.

Nothing can take the enjoyment out of a swimming pool faster than a leak—especially one that cannot be easily found.

A leaking swimming pool can waste hundreds or even thousands of gallons of water, increase chemical usage, drive up utility costs, damage underground plumbing, wash away supporting soil, and create movement beneath the pool deck.

If your pool, spa, fountain, or water feature is losing water, Lone Star Leak Locators provides professional pool leak detection throughout North Texas.

Our goal is not to guess where the leak may be.

Our goal is to inspect, isolate, test, verify, and locate the problem before repair work or demolition begins.

Why Pool Leaks Should Not Be Ignored

A small pool leak may not appear serious at first.

The homeowner may simply add water every few days and assume the loss is caused by the Texas heat.

However, a continuing leak can create larger problems over time.

• Wasted water
• Higher water bills
• Increased chemical costs
• Damage to pool equipment
• Loss of soil beneath the deck
• Movement or cracking around the pool
• Damage to underground plumbing
• Corrosion around fittings and equipment
• Problems maintaining the correct water level
• Damage to nearby landscaping or structures

The sooner the failing system is identified, the sooner the leak can be repaired before additional damage occurs.

Signs Your Swimming Pool May Have a Leak

Your pool may need professional leak testing when you notice:

• The pool needs water added several times each week
• The automatic fill valve operates constantly
• The water level drops 2 inches or more per week
• The pool loses more water than a bucket or tape comparison
• The pump repeatedly loses prime
• Air appears inside the pump basket
• Air bubbles enter the pool through the return fittings
• Wet soil appears near the pool or equipment
• The deck begins to settle or crack
• The pool loses more water while the pump is running
• The pool continues losing water while the pump is off
• The water level stops near a skimmer, light, return, or fitting

Where Swimming Pools Commonly Leak

Pool water can escape through many different parts of the system.

Common leak locations include:

• Skimmer throats
• Cracked skimmer bodies
• Return fittings
• Pool light niches
• Light conduits
• Main drain fittings
• Pool shell cracks
• Tile-line separations
• Underground suction lines
• Underground return lines
• Spa plumbing
• Waterfall and fountain lines
• Deck jets and bubblers
• Pumps, filters, heaters, and valves
• Backwash and waste lines
• Automatic fill systems

Because several of these problems can produce similar symptoms, proper isolation and testing are necessary before repair work begins.

Our North Texas Pool Leak Detection Process

Why a Master Plumber Should Lead Pool Leak Testing

Pool leak detection involves more than placing a gauge on a plumbing line.

The tester must understand pressure, suction, circulation, valves, pumps, fittings, underground plumbing, system isolation, test limitations, and repair planning.

A leaking test plug, trapped air, incorrect valve position, or defective test assembly can create a false pressure-loss result.

That is why a responsible Master Plumber will test the system, verify the test setup, and test again before recommending concrete cutting or excavation.

Pool Leak Detection and Pool Repair Are Separate Phases

Leak detection identifies the failed system and probable repair area.

Repair exposes and corrects the damaged component.

Pool Leak Repairs We May Recommend

Depending on the testing results, the repair may involve:

• Repairing or resealing a skimmer
• Repairing a return fitting
• Sealing a pool light conduit
• Repairing a pool shell crack
• Replacing an underground return line section
• Repairing a suction or skimmer line
• Repairing spa plumbing
• Repairing a water-feature line
• Replacing a leaking valve, union, or fitting
• Repairing a pump, filter, or heater connection
• Cutting and restoring a limited area of concrete
• Excavating and replacing damaged PVC piping

Tools and Equipment Used for Pool Leak Detection

1. Professional Pressure-Test Equipment

Pressure plugs, test manifolds, gauges, hoses, and isolation fittings help determine whether individual pool plumbing lines can maintain pressure.

2. Electronic Geophone and Acoustic Listening Equipment

Acoustic equipment may amplify the sound of air or water escaping from an underground plumbing failure.

3. Dye Testing and Visual Inspection Equipment

Dye syringes, inspection lights, mirrors, cameras, plugs, and visual tools help evaluate pool shell cracks, skimmers, returns, lights, drains, and other fittings.
