What Happens When a Pool Starts to Leak?

A pool leak can be a silent thief, stealing your enjoyment and money over time. The consequences can range from mildly inconvenient to downright dangerous, depending on the severity and location of the leak. Here’s a closer look at the potential repercussions:

Water Loss and Increased Costs:

The most immediate consequence of a leak is the loss of water. This translates to wasted money on refilling the pool, especially during periods of high evaporation. Additionally, the disrupted water balance caused by the leak can lead to increased use of chemicals like chlorine and shock to maintain pool sanitation.

Chemical Imbalance and Water Quality Issues:

As water leaks out, the pool’s chemical balance gets thrown off. This can lead to a number of problems, including:

Algae Growth: Without proper chlorine levels, algae spores can take root and multiply rapidly, turning your once-sparkling pool into a murky green mess.

Skin and Eye Irritation: Imbalanced pool chemistry can irritate swimmers’ skin and eyes, making swimming uncomfortable and potentially hazardous.

Stained Surfaces: Imbalanced water can cause discoloration and staining on the pool walls, floor, and decking.

Structural Damage: A pool leak is more than just an inconvenience; it can also lead to serious structural damage. Here’s how:

Erosion: Water leaking from the pool can erode the surrounding soil, causing the ground to become unstable. This can lead to cracks in the pool deck, patio, or even the foundation of your house.
Shifting Pool Shell: In extreme cases, a significant leak can cause the pool shell itself to shift or settle unevenly. This can result in major structural cracks and costly repairs.

Health Risks: A neglected leak can create a breeding ground for harmful bacteria and mosquitos. Stagnant water with a compromised chemical balance is an ideal environment for these health hazards to thrive.

Signs of a Leaking Pool

Here are some signs that signify your pool might be leaking:

Decreased water level: This is the most obvious indicator. Monitor your water level regularly, especially during periods of low evaporation (cooler months or with a pool cover). A significant drop, especially when the pool isn’t in use, suggests a leak.
Increased water bills: If your water bill spikes unexpectedly, it could be due to a leak refilling the pool.
Cracks in the pool shell or liner: Cracks in the concrete, plaster, or vinyl liner provide a direct path for water to escape. Look closely for hairline cracks, especially around joints, fittings, and skimmers.
Soggy areas around the pool: Water leaking from the pool can saturate the ground surrounding it, leading to soft spots or even puddles.
Running pump but no sound of water movement: If your pool pump is running but there’s no sound of circulating water, it could be a sign that the water is leaking out faster than the pump can bring it in.

How to Detect a Pool Leak on Your Own?

If you suspect a leak, it’s crucial to confirm it before proceeding. Here’s a simple DIY method:

The Bucket Test: Fill a bucket with pool water to the same level as the pool water. Place the bucket on a pool step and mark the water level on both the bucket and the pool. After 24-48 hours, compare the water level drop in the bucket to the pool. If the pool water level has dropped significantly more, you likely have a leak.

While the bucket test is a starting point, it’s not foolproof. For a more accurate diagnosis, consider calling a professional pool service company like JMK Plumbing.

How Does Pool Leak Detection Work in the World of Professionals?

So, you want to know how does pool leak detection work professionally? We’ll outline how we do it at JMK plumbing.

Visual Inspection:

The detection work starts with a thorough visual inspection. A trained technician will examine the entire pool for any telltale signs of damage that could be harboring a leak. This includes:

Cracks: Hairline cracks in the pool shell (concrete, plaster, or fiberglass), liner seams, or around fittings and skimmers are prime suspects. The technician will use a keen eye and bright light to inspect all surfaces.
Loose Fittings: Over time, pool fittings can become loose or misaligned, creating a potential pathway for leaks. The technician will check all pipes, valves, and connections for any signs of looseness or wear.
Deterioration: Pool components like pipes and gaskets can wear out and become brittle over time. The technician will look for signs of deterioration or corrosion that could indicate a leak point.

Water Level Monitoring:

Beyond the initial inspection, the plumbers might employ high-precision water level monitoring tools. These tools can track even the slightest fluctuations in water level over a short period.

By closely monitoring the water level, technicians can gain valuable insights into the severity of the leak. A rapid drop in water level suggests a significant leak, while a slower decline might indicate a smaller leak.

Pressure Testing (for pressure side leaks):

This technique is particularly useful for isolating leaks in the pressurized plumbing network of the pool. The technician will strategically isolate sections of the piping by closing valves.

Compressed air is then introduced into the isolated section. If there’s a leak, the pressure will drop rapidly. By systematically pressurizing different sections of the plumbing, the technician can pinpoint the exact location of the leak within the pressurized system.

Acoustic Leak Detection:

For leaks hidden underground or within pipes buried beneath the pool deck, our technicians at JMK Plumbing might utilize sophisticated acoustic leak detection equipment.

These tools function like underwater microphones, amplifying sounds associated with leaks. The technician will carefully move the listening device around the pool and pipes, honing in on areas where the sound of escaping water is most prominent.

Electronic Leak Detection (for vinyl liner pools):

This method is specifically designed for vinyl liner pools. A low-voltage electrical current is safely introduced into the pool water.

A handheld sensor is then used to scan the pool’s surface. Disruptions in the current flow detected by the sensor indicate the location of a leak in the vinyl liner. The underlying principle is that the electrical current will take the path of least resistance, and a leak in the liner will disrupt the intended flow pattern.

Dye Testing:

This tried-and-tested method can be used to pinpoint leaks in various pool materials. A safe, non-toxic dye is carefully injected into the pool water near suspected leak areas. The technician will then observe the water circulation patterns.

If there’s a leak, the dye will be drawn towards the opening, visually revealing the leak’s location. Dye testing is particularly useful for leaks in areas with slow water movement, where other methods might be less effective.

JMK Plumbing’s experienced technicians understand that a one-size-fits-all approach doesn’t work in pool leak detection. They will carefully assess your specific pool type, construction materials, and the nature of the suspected leak to choose the most appropriate combination of these techniques.

This ensures a swift and accurate diagnosis, allowing them to get your pool leak fixed quickly and efficiently.

How to Repair a Leaking Pool?

Once the detection work is done and our technicians have identified the culprit behind your pool leak, they’ll recommend the most suitable repair method. Here’s a breakdown of the general steps involved in fixing a pool leak, along with some considerations for different leak scenarios:

1. Preparation:

Safety First: Before any repairs begin, the pool needs to be prepped to ensure the safety of both the technicians and the work area. This may involve draining some or all of the pool water, depending on the leak location and repair strategy. The pool’s electrical system might also be temporarily shut down as a safety precaution.

Access Point Creation: For leaks that require access to the underside of the pool liner or repairs within the shell itself, a temporary access point might need to be created. This could involve carefully cutting a section of the pool deck or excavating a specific area around the pool wall. Our technicians will create the most strategic access point possible, minimizing disruption to the surrounding area.

2. Leak Repair:

Small Cracks and Holes: For hairline cracks or minor holes in the pool shell (plaster, concrete, or fiberglass), one might need to utilize epoxy patching compounds or underwater-grade cements.

These specialized materials are designed to adhere tenaciously to wet surfaces and create a watertight seal. In some cases, fiberglass mesh might be used to reinforce the repair area.

Vinyl Liner Patching: Small punctures or tears in vinyl liners can often be effectively repaired using vinyl patches specifically designed for pool applications. These patches are made from high-quality waterproof material and come with a strong adhesive backing.

The technician will clean and dry the area around the leak before applying the patch, ensuring a long-lasting repair.

Pipe Leak Repair: Leaks originating from pipes or fittings require a more involved approach. Depending on the location and severity of the leak, the technicians might employ strategies like:

Pipe Clamp Installation: Specialized clamps can be used to create a watertight seal around a leaky pipe section. This is a viable option for minor leaks that haven’t compromised the integrity of the pipe itself.
Pipe Replacement: If the leak is significant or the pipe is damaged beyond repair, the technician might need to replace the affected section of piping. This will involve carefully cutting out the damaged section and soldering or welding in a new pipe segment.
Leak Sealer Products (cautious application): While not a permanent solution, leak sealer products can sometimes be used as a temporary fix for minor leaks in hard-to-reach pipes.

JMK Plumbing will advise on the pros and cons of using leak sealers and only recommend them in specific scenarios where they can provide a stopgap measure until a more permanent repair can be implemented.

3. Pressure Testing and Leak Verification:

Once the leak repair is complete, the technician will re-fill the pool (if necessary) and conduct a pressure test. This test involves pressurizing the pool’s plumbing system to a specific level and monitoring it for any pressure drops.

A steady pressure reading indicates a successful repair, while a drop in pressure signifies that the leak persists. If a leak is still detected, the technicians will revisit their diagnosis and employ additional leak detection techniques to pinpoint the remaining leak.

4. Restoration and Finishing Touches:

Following a successful leak repair and pressure test, JMK Plumbing will focus on restoring the affected areas around the pool. This might involve:

Smoothing and Resurfacing: Repaired cracks or holes in the pool shell might require smoothing and resurfacing to create a seamless and aesthetically pleasing finish.
Deck Repair or Replacement: If the leak necessitated creating an access point through the pool deck, the technicians will repair or replace the affected deck section to restore its original look and functionality.
Chemical Balancing and System Restart: After refilling the pool (if necessary), JMK Plumbing tests and adjusts the pool’s chemical balance to ensure proper sanitation and safe swimming conditions. The pool’s filtration and circulation systems will also be restarted to resume normal operation.

We understand that a pool leak can be disruptive to your backyard oasis. Their experienced technicians will work efficiently to diagnose and repair the leak while minimizing the impact on your pool’s overall aesthetics and functionality.

They’ll keep you informed throughout the process and ensure your pool is back in top shape for you to enjoy worry-free.
