What Happens During a Professional Pool Leak Detection Visit in Columbia, MS

You have been watching your pool lose water for weeks. You have topped it off so many times it has become a routine. But topping it off is not a fix. It is just delaying the conversation your pool is trying to have with you.

For homeowners in Columbia, MS, a professional pool leak detection visit from A & H Leak Detection & Repair takes the guesswork out of that conversation entirely. This post walks you through exactly what to expect from start to finish so you can book with confidence and know what you are getting.

Why a Professional Visit Beats DIY Leak Hunting

There is a bucket test. There are dye tests. There are YouTube videos on how to check your pool equipment for drips. And for about 5 to 10 percent of pool leaks, those methods might point you in the right direction.

But most pool leaks are not visible. They are not in the obvious place. A leak in an underground return line looks identical to evaporation from the outside. A crack in the shell behind a fitting looks identical to normal water movement. Without the right electronic equipment and the training to use it, you are guessing.

At A & H Leak Detection & Repair, we use Leaktronics electronic testing equipment and non-invasive methods to find leaks accurately the first time. That precision matters because every wrong guess means more water lost, more chemicals wasted, and more stress on your pool structure while you wait.

Before the Visit: What to Do to Prepare

You do not need to do much before our team arrives. A few things that help:

Note your water loss. If you have been tracking how much water your pool loses per day or week, that information is useful. Even a rough estimate gives us a starting point for how significant the leak is likely to be.

Do not add water the day before if possible. Starting from a stable water level helps with certain measurements during the visit.

Make sure the equipment area is accessible. The pump, filter, and any valves near the pool should be reachable without moving furniture or other obstacles.

Write down anything unusual you have noticed. A soft spot in the yard near the pool, a fitting that has been dripping, a change in water pressure from a return jet, a crack you spotted in the shell. All of it is useful context.

That is genuinely it. You do not need to drain the pool, move anything heavy, or do any prep work beyond that.

Step One: The Initial Assessment

When our technician arrives at your Columbia home, the visit starts with a walkthrough and a conversation.

We want to know how long you have noticed the water loss, roughly how much per day or per week, whether anything has changed recently on the equipment side, and whether you have spotted anything physically unusual around the pool or in the yard.

From there, we do a visual inspection of the full pool area. We look at the shell for visible cracks, check the tile line, inspect the skimmer baskets and skimmer body, look at the returns and main drain covers, and check all equipment connections at the pump and filter.

This walk-around rarely reveals the leak outright. But it tells us where to focus first and rules out the easiest explanations before we move to testing.

Step Two: The Pressure Test

Pressure testing is how we separate structural leaks from plumbing leaks. This matters because the repair approach is completely different depending on which one you have.

We isolate and pressurize the underground plumbing lines. Return lines, suction lines, and the main drain line are each tested independently. A line that holds pressure is intact. A line that bleeds pressure down has a breach somewhere along its route.

Pressure testing does not tell us exactly where the leak is. It tells us which line is leaking. That narrows the search area significantly before we move to acoustic detection.

For Columbia homeowners with pools that have been in the ground for more than 10 to 15 years, underground line failures are common. The Mississippi climate puts pipes through years of heat, ground movement, and root pressure that eventually takes a toll on fittings and pipe joints.

Step Three: Electronic Leak Detection

This is the step that separates professional detection from everything else.

Using Leaktronics listening equipment, our technician moves along the pool shell, the equipment pad, and the pipe routes detected as suspect in the pressure test. The equipment amplifies the sound of water escaping under pressure through concrete, soil, and pipe walls. A trained ear can identify the exact location of a leak from the distinctive frequency it produces.

For underground lines, we listen along the pipe route and zero in on the point where the leak sound is loudest. For shell leaks, we work systematically along the walls and floor. For equipment leaks, we check fittings, unions, and seals under operating pressure.

The precision here is what makes non-invasive repair possible. When we know exactly where a leak is located down to within a few inches, any excavation or repair access is targeted and minimal. We are not digging up your Columbia backyard to find something. We are going directly to it.

Step Four: Dye Testing for Structural Confirmation

For any area of the pool shell or fittings where we suspect a crack or breach, we use dye testing to confirm.

A small amount of leak detection dye is released near the suspected area. If there is an active draw from a crack or gap, the dye is pulled directly toward it and disappears into the breach. If the shell is intact, the dye disperses evenly into the surrounding water.

Dye testing is simple but definitive. It confirms the location of structural leaks before we mark anything for repair, and it eliminates false positives from the acoustic step.

Step Five: The Report and Repair Conversation

Once testing is complete, we walk you through everything we found.

We show you the leak locations, explain what caused them where we can determine that, and lay out your repair options. For underground line leaks, that might include pipe relining, spot excavation and fitting replacement, or rerouting a line in severe cases. For shell leaks, that typically means epoxy injection, fitting replacement, or plaster repair depending on the type and size of the breach.

We do not push you toward the most expensive repair option. We give you an honest picture of what the situation is and what approach makes the most sense for the specific leak type and your pool's age and condition.

A & H Leak Detection & Repair is a veteran-owned business, and that means something in practice. Straightforward, honest service is not a marketing line. It is how we operate every visit.

How Long Does the Visit Take?

For a standard residential pool in Columbia, a full detection visit typically runs two to three hours. That covers the initial assessment, pressure testing, electronic detection, dye confirmation, and the findings walkthrough.

Larger pools, pools with extensive underground plumbing, or pools where multiple leak sources are suspected may take longer. We give you an honest time estimate at the start of the visit so you can plan accordingly.

What Happens After Detection?

If A & H completes your repair on the same visit, the pool is typically ready to refill and return to normal operation within 24 to 48 hours depending on the repair type.

If the repair requires scheduling a return visit, we walk you through what to expect in terms of timeline and whether the pool needs to remain out of service in the meantime.

In most cases, Columbia homeowners are back in the water faster than they expected. The detection step is the longest part. Once we know exactly where the problem is, repairs move quickly.

FAQ: Professional Pool Leak Detection in Columbia, MS

How do I know if my pool is actually leaking or just losing water to evaporation?

The bucket test is the standard starting point. Fill a bucket with pool water and set it on a pool step so it sits at the same water level as the pool. Mark both water levels. After 24 hours, compare the loss. If the pool has lost noticeably more water than the bucket, you have a leak rather than evaporation. Columbia summers are hot enough that evaporation alone can account for a quarter inch or more per day, so the comparison step matters.

Does A & H Leak Detection & Repair serve Columbia, MS?

Yes. Columbia is within our service area. A & H Leak Detection & Repair serves homeowners and commercial properties within 50 miles of Hattiesburg, which covers Columbia and the surrounding Marion County area. Call (601) 466-8082 to schedule your visit.

Will your technician need to drain my pool to find the leak?

No. Our detection process is performed with the pool full and operating. Draining a pool to find a leak is an older approach that is both unnecessary and potentially damaging to the shell. We locate leaks through pressure testing, electronic acoustic detection, and dye testing, all done at normal water level.

Can a pool leak cause damage to the yard or foundation?

Yes, and this is one of the reasons prompt detection matters. An underground line leak can saturate the soil beneath and around the pool over time, which leads to settling, erosion, and in some cases undermining of the surrounding hardscape or pool deck. In Marion County's clay-heavy soils, water saturation also creates soil movement that compounds the problem. The longer a leak runs undetected, the more the surrounding ground is affected.

What types of pool leaks do you detect and repair?

A & H Leak Detection & Repair handles pool shell leaks including cracks and fitting failures, underground return and suction line leaks, skimmer body cracks, main drain issues, and equipment pad leaks at fittings and unions.
