Detection First, Repair Second
Most pool companies jump straight to repair. We don’t, because a repair is only as good as the diagnosis behind it. Our process is built around three steps: locate the leak with the right equipment, confirm it, and then repair the actual problem, not the most visible crack. That order matters more than people expect.
Signs Your Pool May Have a Leak
- Losing more than a quarter inch of water per day beyond normal evaporation
- An unexplained rise in your water bill
- Wet or soggy areas near the equipment pad or decking
- Cracks in the pool deck, shell, or coping
- Air bubbles at return jets or in the pump basket
- The auto-fill running more frequently than usual
- Chemical levels that are hard to balance and keep balanced
A simple way to confirm you have an actual leak rather than normal evaporation is the bucket test: place a bucket on the pool step filled to the same water level as the pool, mark both levels, and compare after 24 hours. If the pool drops noticeably more than the bucket, you likely have a real leak worth investigating.
A Plano homeowner once called us convinced the leak had to be in the shell, since that’s where the wet spot in the yard kept showing up. The dye test told a different story: the actual leak was a cracked return line under the decking, ten feet away from where the water was surfacing. Water underground follows the path of least resistance, which is exactly why the wet spot and the leak aren’t always in the same place. That job ended up being a straightforward spot repair on the return line, not a shell patch that would have solved nothing.
How We Detect a Pool Leak
- Electronic listening equipment: A sensitive underwater microphone and amplifier used to listen for the sound of pressurized water escaping a pipe beneath the decking or shell, narrowing the leak to a general area before any digging begins.
- Pressure testing equipment: Each plumbing line, including the skimmer, main drain, and returns, is isolated and pressurized individually. A line that will not hold pressure tells us exactly which pipe is compromised.
- Dye testing kits: A concentrated dye is released near suspected problem areas such as skimmer throats, light niches, and shell cracks. Actively leaking water visibly pulls the dye toward the opening, confirming the exact leak point.
How We Repair What We Find
Once the leak is confirmed and documented, the repair path usually falls into one of a few categories:
- Plumbing spot repair: A localized fix on a cracked or separated return, suction, or fill line.
- Line reroute: Installing a new section of pipe when the existing line is old, hard to access, or has multiple problem points.
- Fitting or gasket replacement: Common at skimmer throats and light niches, where seals degrade over time.
- Structural shell patch: Addressing a confirmed crack in the pool surface itself, distinct from a plumbing issue.
Every recommendation ties back to what the detection equipment actually showed, not a guess about what’s probably wrong.
Why Pools in Plano and North Dallas Develop Leaks
North Texas sits on expansive clay soil that swells and contracts with the seasons, and that movement puts ongoing stress on in-ground pool shells and the plumbing running beneath and around them. Over time this can lead to cracked returns, separated fittings, and pinhole leaks, even in pools that were built well. We see this pattern consistently across Plano, in Dallas neighborhoods on similar soil, and in newer Frisco construction where a pool can develop leaks from soil settlement in its first few years.
Detection and Repair vs. Guessing
| Approach | What Happens | Risk |
|---|---|---|
| Patching the most visible crack | A repair is made without confirming it is the actual leak source | Water loss continues, repair cost is wasted |
| Electronic, pressure, and dye testing | Structure and plumbing are each tested to isolate the true source | Minimal, though some equipment pad access may still be needed |
| Detection plus documented repair | Findings and repair recommendation delivered in a written Master Plumber Report | Gives you a record for your pool builder, contractor, or insurer |

Reference Section: Plumbing Code Topics
Pool plumbing repair should be evaluated with attention to backflow prevention, pipe sizing, and equipment pad code requirements. Always verify the current adopted code edition and local amendments with your city’s building department before repair work begins.
| # | Code Topic | Why It Matters | Code |
|---|---|---|---|
| 1 | IPC Backflow Prevention | Governs cross-connection protection between pool fill lines and potable water supply. | Code |
| 2 | UPC Water Piping Installation | Reference for protecting pressurized piping from abrasion, corrosion, and improper burial depth. | Code |
What Our Customers Say
★★★★★
“We were adding two inches of water a week and had no idea where it was going. They pressure tested every line at the pad, found a cracked return in about 40 minutes, and repaired it the same visit. No more guessing, no unnecessary digging.”
— Plano, TX homeowner
★★★★★
“The dye test found a hairline crack right at the light niche that we would have never spotted on our own. The written report made it easy to get the repair approved and done without any back and forth.”

Frequently Asked Questions (FAQs)
Is a sewer scope inspection really necessary?
For sewer-related concerns, yes. A sewer scope inspection shows the actual condition of the line rather than relying on guesswork, which can prevent paying for the wrong repair.
How long does a sewer scope inspection take?
Most sewer scope inspections take between 30 and 60 minutes, depending on the length of the line and how many access points are available.
Will I receive a video of the inspection?
Yes, camera-based inspections include recorded video, and pool leak detection findings are documented in a written, certified Master Plumber Report.
Can a sewer scope detect all problems?
A sewer scope can detect most structural and drainage issues within reach of the camera, but it cannot see problems in sections that are inaccessible or blocked.
What happens if problems are found?
We explain what was found in plain language, document it in your report, and complete the recommended repair so you’re not left choosing between multiple contractors.
Is this service included in a standard home inspection?
No. Standard home inspections typically do not include pool leak detection or sewer scope inspections, since both require specialized equipment and training.
How much can sewer repairs cost?
Sewer repair costs vary widely depending on the defect, depth, and access, and can range from a few hundred dollars for a minor spot repair to several thousand for a full line replacement.
How much does pool leak detection and repair cost in Plano?
Detection typically starts in the $600 to $700 range. Repair costs on top of that vary depending on whether the fix is a simple gasket replacement, a plumbing spot repair, a reroute, or a structural shell patch.
How do you know if the leak is in the pool shell or the plumbing?
We isolate the plumbing lines with pressure testing first. If every line holds pressure, the leak is likely structural, and we move to dye testing around the shell, skimmer, and light niche.
Can I test for a pool leak myself before calling a professional?
Yes, the bucket test is a simple way to confirm you have an actual leak versus normal evaporation. Beyond that, pinpointing the exact source requires professional equipment.
Is a pool leak an emergency?
It can be if the water level drops below the skimmer, which can damage the pump, or if the leak is undermining decking or nearby foundation soil. Otherwise it is usually safe to schedule.
Will my pool need to be drained for leak detection or repair?
Detection is usually performed with the pool full. Some repairs, such as a shell patch below the waterline, may require partial draining, which we’ll explain before starting.
What is the difference between a spot repair and a full reroute for pool plumbing?
A spot repair fixes the specific damaged section of pipe, while a reroute installs a new line entirely, which may make sense if the existing plumbing is old or difficult to access.
Can a pool leak affect my home’s foundation?
Yes, a significant or long-term pool leak near the home can saturate soil unevenly, which is worth addressing promptly given Plano’s expansive clay soil conditions.
Do you provide a written report after pool leak detection and repair?
Yes. Every job includes a certified Master Plumber Report documenting what was found and what was repaired, prepared by a Texas Licensed and Registered Master Plumber, License #45825.
