A Dallas homeowner notices their pool is down a few inches. They top it off. A week later, it is down again. Is the pool leaking, or is the Texas summer heat just evaporating the water faster than expected?
Both things happen. The difference matters because evaporation is normal and expected. A leak needs to be found and fixed before it damages your pool structure, your landscaping, and possibly your foundation.
Here is how to tell the difference and what to do about it.
Normal Water Loss vs. an Actual Leak
In Dallas, summer evaporation rates for pools run roughly 1/4 to 1/2 inch per day during peak heat. That equals about 1 to 3 inches per week under normal conditions. If you are losing significantly more than that, especially if the loss is consistent and does not track with temperature swings, it is worth investigating.
Other signs a pool might be leaking:
- You are adding more than 2 inches of water per week consistently
- The water level drops more when the pump is running than when it is off, or the opposite
- Wet spots, soggy ground, or unusual grass growth near the pool equipment or plumbing lines
- Cracks in the pool shell or settling or movement of the deck
- Your water chemistry is constantly off even with regular treatment
The Bucket Test: Your First Step
Before calling anyone, run the bucket test. It is the standard homeowner method for distinguishing evaporation from a leak.
How to Perform the Bucket Test
- Fill a 5 gallon bucket with pool water to about an inch from the top
- Set the bucket on the first or second step of the pool so it is partially submerged
- Mark the water level inside the bucket and the pool water level on the outside of the bucket
- Leave the pool pump running normally for 24 hours, then check again
How to Read the Results
Compare the water levels. If the pool lost significantly more water than the bucket, you likely have a leak.
The bucket is exposed to the same evaporation and splash conditions as the pool. If the pool loses more than the bucket over the same period, something beyond normal evaporation is happening.
Where Do Pool Leaks Come From?
Shell and Structure
Cracks in the pool’s gunite or plaster shell can leak water directly into the surrounding soil. Structural cracks, often caused by soil movement common in Dallas clay-heavy conditions, can develop slowly and be hard to spot visually. Underwater cracks are especially difficult to identify without professional equipment.
Plumbing Lines
Underground plumbing that carries water to and from the pool is a common source of leaks. Fittings, joints, and the pipe itself can develop leaks over time. Pressure testing and specialized listening equipment are required to locate plumbing leaks.
Equipment and Fittings
Pump housing, filter connections, backwash valves, and return fittings can all develop leaks above or below ground. Some equipment leaks are visible at the pad. Look for damp soil or staining around equipment. Others are underground and harder to find.
Lights and Penetrations
Pool light fixtures are a common source of leaks. The conduit that runs from the light niche through the pool shell can allow water to escape if the seal fails. Skimmer penetrations are another frequent leak point.
What Does Professional Pool Leak Detection Involve?
Professional leak detection goes beyond the bucket test. When Liquidus Pool Services investigates a suspected pool leak, the process typically includes:
- Pressure testing the plumbing lines by pressurizing the system and monitoring for pressure drop to identify underground leaks
- Dye testing at suspected areas by injecting colored dye near fittings, cracks, and light niches to visually identify where water is escaping
- Equipment area inspection by checking all visible plumbing connections, fittings, and equipment for signs of leakage
- Electronic leak detection equipment that can detect the sound of water moving through cracks or pipe breaks underground
The goal is to precisely identify the source before any repair work begins. A repair done without knowing the exact source is expensive guesswork.
What Happens After a Leak Is Found?
Repair options depend on where the leak is and how serious it is. Shell cracks can often be repaired underwater by injection or patching. Plumbing leaks may require excavation to access and repair or replace the pipe section. Equipment fittings are generally the most straightforward to fix.
In some cases, a leak discovery also reveals underlying issues such as structural movement, aging plumbing, or equipment that is at the end of its life. A thorough leak detection often turns into a broader assessment of the pool’s overall condition.

FAQ: Pool Leak Detection in Dallas
1. How much water loss is normal for a Dallas pool?
1/4 to 1/2 inch per day in summer heat is within the normal evaporation range. If you are consistently losing more than that, especially more than 2 inches per week, it warrants investigation.
2. Can I find a pool leak myself?
The bucket test is a reliable DIY first step. Beyond that, locating the source of a leak, especially in plumbing or underwater structure, requires specialized equipment. Most homeowners find professional detection worth the cost compared to guessing.
3. How long does pool leak detection take?
A standard professional leak detection inspection typically takes 2 to 4 hours depending on pool size and complexity. If the leak is in the plumbing, additional pressure testing may extend the process.
4. What does pool leak detection cost in Dallas?
Professional leak detection services typically range from $200 to $500 depending on scope. That cost is often recovered quickly through reduced water bills and by avoiding more expensive damage.
5. Can a pool leak damage my foundation?
Yes. Significant pool leaks that saturate the soil near your home’s foundation can cause erosion and settlement issues. This is a serious concern in Dallas clay-heavy soils, which already experience movement. Address leaks promptly rather than continually topping off the pool.
6. Does homeowner’s insurance cover pool leaks?
It depends on the policy and the cause. Sudden and accidental leaks may be covered. Gradual leaks resulting from normal wear and neglect typically are not. Check your specific policy and consult with your insurer.
