What Does a Pool Diver Do?
A pool diver is a trained diver who can access areas of a swimming pool that are difficult or impossible to properly inspect from the surface. Atlantic Pool Leak Detection uses professional pool divers as part of our leak detection and underwater repair services for in-ground swimming pools.
A swimming pool diver can closely inspect submerged components, perform dye testing around suspected leak locations, evaluate vinyl liners and fittings, access pool lights and main drains, and complete certain repairs while the pool remains filled.
For homeowners searching for pool divers near them because their pool is losing water, there is an important distinction to understand: a pool diver can be extremely useful for investigating underwater areas, but diving alone is not the same as complete pool leak detection.
Professional Pool Divers for Leak Detection and Repair
Atlantic Pool Leak Detection uses pool divers for both diagnostic and repair work when underwater access is appropriate.
During pool leak detection, a diver may inspect areas such as:
- Vinyl pool liners
- Main drains and drain covers
- Pool lights and light niches
- Skimmers and fittings
- Returns and other pool penetrations
- Suspected cracks or structural leak locations
Dye testing can also be performed underwater around suspected areas to determine whether water is actively being drawn through a particular opening.
Once the source of a leak has been confirmed, a pool repair diver may be able to complete certain repairs without draining the swimming pool. The type of repair that can be performed depends on the material, location, accessibility, and nature of the damage.
If you already know that your pool needs work below the waterline, visit our underwater pool repairs page for more information about repairs that may be completed while the pool remains filled.
Pool Diver Certification and Equipment
Atlantic Pool Leak Detection’s pool divers are PADI SCUBA certified and use professional diving equipment to safely access submerged areas of swimming pools.
Depending on the job, a diver may also use leak detection tools such as dye-testing equipment and other equipment appropriate for inspecting or repairing suspected underwater leak locations.
The equipment is only part of the process. Knowing where to look, understanding how different pool components can leak, and recognizing when an underwater finding does or does not explain the pool’s water loss are equally important.
Finding one suspicious area underwater does not automatically mean the diagnostic process is finished. If the pool continues losing water or the symptoms point toward another part of the system, additional testing may be necessary.
Underwater Pool Repairs Without Draining Your Pool
Many homeowners assume that a leak below the waterline means the swimming pool has to be drained before anything can be repaired.
That’s often not the case.
A trained swimming pool diver can perform many repairs while the pool remains full. This avoids wasting thousands of gallons of water and eliminates the time required to drain and refill the pool.
It can also avoid some of the risks associated with unnecessarily draining a swimming pool.
The exact repair depends on the type of pool and the location of the problem, but we’ll determine whether an underwater repair is appropriate before recommending that you lower the water level.
You can learn more about the types of work we complete on our Underwater Pool Repairs page.
Vinyl Liner Pool Diver Repairs
Small holes and tears in vinyl liners are some of the most common problems that can be repaired underwater.
A liner can develop leaks from punctures, wear, damage around fittings, or other failures below the waterline. Small holes can be extremely difficult to locate visually, particularly when there is no obvious tear.
Once the leak has been accurately located, many liner problems can be patched by a pool diver without draining the swimming pool.
That means you may not need to replace an otherwise serviceable liner simply because it has developed a repairable leak.
For more information about finding and repairing these problems, visit our Vinyl Liner Leak Repair page.
Gunite and Concrete Pool Diver Repairs
Gunite and concrete swimming pools can also develop leaks below the waterline.
Problems may occur around cracks, fittings, penetrations, lights, drains, and other areas of the pool structure.
Once the source has been confirmed, certain leaks can be sealed underwater using repair materials appropriate for the problem.
The important part is confirming that the area being repaired is actually responsible for the water loss.
A visible crack does not automatically mean you’ve found your leak. If the pool is losing water and the source has not yet been established, leak detection should come before repair.
Pool Light Niche Repairs
Pool lights are another area where underwater diving can be extremely useful.
Leaks can develop around the pool light niche, conduit, sealing material, or surrounding structure. Because the entire assembly is below the waterline, the problem can be difficult to properly evaluate from the deck.
Our pool divers can access the light assembly underwater, evaluate suspected leak areas, and complete certain repairs without draining the pool.
We’ve diagnosed pool-light leaks that previous companies missed because the actual problem was hidden below the surface.
Fiberglass Pool Underwater Repairs
Fiberglass swimming pools can develop leaks around fittings, penetrations, lights, and damaged areas of the pool surface.
Depending on the type and location of the failure, some fiberglass pool repairs can be performed underwater.
Before making the repair, we first want to understand exactly where the water is escaping. That prevents an obvious-looking area from being repaired while the actual leak remains somewhere else.
Pool Drain and Drain Cover Services
Our swimming pool divers can also access main drains and other components located at the deepest point of the pool.
This may include replacing or installing certain drain covers and performing underwater work that would otherwise be extremely difficult without diving equipment.
For commercial and public pools, drain-cover requirements can involve additional safety and compliance considerations. We can discuss the specific work required before scheduling the underwater service.
What a Pool Diver Cannot Find
A pool diver cannot visually inspect a pipe that is buried beneath a pool deck, patio, or yard.
This distinction matters because a pool can be losing water from an underground return line, skimmer line, main drain line, cleaner line, spa line, or other buried plumbing even when everything visible inside the pool appears normal.
If the source of the water loss is unknown, complete pool leak detection may require pressure testing, electronic or acoustic detection, dye testing, and underwater evaluation depending on the symptoms.
Pressure testing can help determine whether an individual plumbing line leaks. If a line fails, additional equipment can then be used to help pinpoint where the underground break is located.
Diving is an important tool in pool leak detection, but it is only one part of the diagnostic process when the source of the leak is unknown.
Need an Underwater Pool Repair?
If the leak or damaged component has already been located below the waterline, you may not need to drain the entire swimming pool to have it repaired.
Atlantic Pool Leak Detection performs appropriate underwater swimming pool repairs using professional pool divers. Depending on the problem, this may include certain vinyl liner patches, pool light and fitting repairs, drain-related work, and other repairs that can be safely completed underwater.
This is the primary difference between finding a pool diver and scheduling complete pool leak detection. If you already know what needs to be repaired underwater, a pool repair diver may be the appropriate next step. If you only know that your pool is losing water, the source should be diagnosed first.

Do You Need a Pool Diver or Pool Leak Detection?
This is an important distinction.
If you already know where the problem is and need someone capable of reaching and repairing it underwater, a pool diver may be exactly what you need.
If your pool is simply losing water and you don’t know where it’s leaking, hiring someone who only dives into the pool may not solve the problem. That’s because a swimming pool can leak from two broad areas:
Inside the pool itself, including the liner, shell, lights, skimmers, fittings, drains, and other penetrations.
Outside the pool, particularly underground plumbing lines running between the pool and equipment.
A diver can evaluate accessible areas inside the swimming pool.
A diver cannot visually inspect a broken pipe buried several feet beneath your patio or yard.
Atlantic Pool Leak Detection does both underwater work and complete diagnostic leak detection. If the source is unknown, we can evaluate the pool and its plumbing rather than assuming the problem must be somewhere a diver can see.

What a Pool Diver Cannot Find Underwater
Pool diving is extremely useful when the problem is located inside the pool.
It has limitations.
A pool diver cannot visually locate an underground break in a:
- Return line
- Skimmer line
- Main drain line
- Spa plumbing line
- Cleaner line
- Water-feature plumbing line
Those pipes need to be properly tested.
When an underground plumbing leak is suspected, we can isolate and pressure test individual lines to determine whether they hold pressure. If a line fails testing, specialized electronic and acoustic equipment can then be used to help pinpoint where the pipe is broken underground.
Read more about underground pool plumbing leak detection and how these hidden problems are diagnosed.
Pool Diver vs. Complete Pool Leak Detection
Think of the difference this way:
A pool diver gives us physical access to the underwater portions of the swimming pool.
Professional pool leak detection gives us the ability to diagnose the entire system.
Sometimes diving is exactly what the job requires. Other times we need pressure testing, dye testing, electronic listening equipment, or a combination of methods.
Atlantic Pool Leak Detection isn’t limited to one method. If the leak is in the liner, we can find it. If it’s around a light, we can test it. If we need to dive the pool, we can dive it.
If the problem is an underground plumbing line, we can pressure test it and work to pinpoint the break.
That’s why homeowners who don’t yet know where their pool is leaking should start with our complete Pool Leak Detection Services rather than booking a visual-only diving service.
What Happens During an Underwater Pool Repair?
Before we get into the pool, we want to understand what needs to be repaired.
If the leak location is already known, we’ll evaluate the repair and determine whether it can be completed underwater.
If the location is unknown, diagnostic testing may need to come first.
For an underwater repair, our diver enters the pool with professional diving equipment and accesses the affected area directly. The exact process and materials depend on the pool construction and the type of repair being performed.
In many cases, there is no need to:
- Drain the entire pool
- Wait days for the pool to refill
- Waste thousands of gallons of water
- Disrupt the entire backyard
- Keep the pool unusable for an extended period
We’ll tell you what is appropriate for your particular repair rather than assuming every underwater problem requires the same solution.

Frequently Asked Questions About Pool Divers
Can a pool diver repair a leak without draining the pool?
Yes. Many underwater pool leaks can be repaired while the swimming pool remains full. This may include vinyl liner patches and certain repairs involving lights, fittings, gunite, concrete, or fiberglass surfaces.
What types of repairs can a swimming pool diver perform?
Depending on the pool and problem, a professional pool diver may perform vinyl liner patches, light niche repairs, certain structural repairs, fitting repairs, drain-cover work, dye testing, and other underwater pool services.
Can a pool diver find a swimming pool leak?
A pool diver can help locate leaks in accessible areas inside the swimming pool, but diving alone cannot evaluate the entire pool system. Underground plumbing leaks require pressure testing and specialized diagnostic equipment.
Can a pool diver find an underground plumbing leak?
No. Underground pipes are buried outside the swimming pool and cannot be visually inspected by a diver. Plumbing lines need to be pressure tested, and additional electronic or acoustic testing may be required to pinpoint an underground break.
Do I have to drain my pool for a vinyl liner repair?
Often, no. Many vinyl liner leaks can be located and patched underwater by an experienced pool diver while the pool remains filled.
Can a pool light leak be repaired underwater?
In many cases, yes. The exact repair depends on where the light assembly is leaking and the condition of the niche, conduit, sealing material, and surrounding structure.
Can a pool diver work in the deep end?
Yes. Professional SCUBA equipment allows a trained pool diver to access submerged components throughout the pool, including areas in the deep end that cannot be reached safely from the surface.
How do I know if I need a pool diver or a leak detection company?
If you already know the exact underwater repair that needs to be completed, pool diving services may be appropriate. If your pool is losing water and you do not know where it is escaping, start with complete pool leak detection so both the pool structure and plumbing can be evaluated.
