Every pool in North Texas loses some water to the sun and wind. A leak is different: the water level keeps dropping faster than normal, the auto-fill runs all the time, or you see soggy ground near the pool. Finding the exact spot keeps the repair small.

Is my pool leaking or just evaporating?

In an Arlington summer, a pool can lose about a quarter inch of water a day to evaporation, sometimes more on hot, windy days. If your pool drops more than that, or keeps dropping with the pump off, a leak is likely. The bucket test is the easiest way to tell.

1. Fill a bucket with pool water and set it on the first or second step.
2. Mark the water level inside the bucket and on the outside wall of the bucket at the pool level.
3. Run the pump as usual for 24 hours, and do not add water.
4. Compare the two drops. If the pool dropped more than the bucket, you likely have a leak.

Our guide to pool leak or evaporation walks through the test with photos and what each result means.

What are the signs of a pool leak in Arlington?

The most common signs are a water level that drops more than about a quarter inch a day, an auto-fill that runs constantly, a higher water bill in summer, wet or sinking ground near the pool, cracks in the deck or plaster, loose tiles, and algae that returns right after treatment because fresh water keeps diluting the chemicals.

• Water level drops faster with the pump on (often a pressure-side leak)
• Water level drops faster with the pump off (often a suction-side or shell leak)
• Air bubbles at the return jets
• Soggy grass or mud between the pool and equipment pad
• Cracks in the plaster, tile line or deck
• Water around the pump, filter or heater

How do you find a pool leak?

We start with the simple checks and move to the precise ones. Pressure testing isolates each plumbing line. Dye testing shows if water is pulled into a crack, light niche, skimmer throat or return fitting. Underwater listening gear and ground microphones locate leaks on buried lines so only a small area is opened.

How much does pool leak detection cost in Arlington?

Pool or spa leak detection in Arlington usually costs about $250 to $550.

Do you do hot tub leak detection?

Yes. Hot tub leak detection in Arlington uses the same tools as a pool: a pressure test on the spa lines, dye at the jets, light and fittings, and listening for escaping water. Attached spas often leak at the spillover, the jet bodies or the shared lines to the pool. Stand-alone hot tubs usually leak at pump unions, heater fittings or a cracked jet.

If your spa drops more than an inch or two a week with the cover on, or the equipment pad stays wet, book a test before the water damages the cabinet or the deck. Our hot tub leak detection page covers where spas leak and what to check first.

Why do pools in Arlington leak?

Arlington pools sit in expansive clay soil that swells after rain and shrinks in long, hot summers. That movement can crack plaster, separate the tile line and stress buried plumbing. Hard freezes, like Winter Storm Uri in 2021, can also split exposed pipes at the equipment pad.

Older pools in North Arlington, Woodland West and around Lake Arlington often have original plumbing and light niches that have worn over the years. Sprinkler lines next to the pool can also leak and look like a pool leak, so we check both. See our guide to sprinkler and irrigation leaks.

What happens after the leak is found?

We mark the leak, show you what we found, and explain the repair. Small leaks at fittings, lights and skimmers can often be sealed the same visit. Leaks in buried lines need a small opening in the deck or yard. Larger shell cracks may need a pool contractor, and we tell you that plainly.

If the pool checks out but your water meter still moves, the leak may be in the house. Then slab leak detection is the next step.
