Causes of Swimming Pool Leaks | Leak Science

For most families, swimming in the pool is the best summertime activity. You can spend the day with family and friends, eat delicious food cooked on the grill, and laugh for hours. But now that summer is in full swing, have you checked to make sure your pool isn’t leaking? Unfortunately, there are many causes of swimming pool leaks, so you should know what to look for.

Causes of Swimming Pool Leaks

Here are just some of the causes of swimming pool leaks:
  • A swimming pool leak can be caused by issues with the pumps and motors.
  • Leaks can occur as a result of normal wear and tear on the pool surface.
  • Water can soak the ground if the plumbing beneath the pool deck breaks.
  • Leaks are caused by loose connections on railings, tiles, and other accessories.

Spa tubs and other in-ground water features are similarly affected by these issues.

A leak in an in-ground pool may be more difficult to locate, you must address it immediately to avoid ground saturation, flooding, and water waste. There are several risk factors for leakage depending on the type of in-ground pool.

Your summertime fun will have to wait if your pool suddenly loses water or begins to malfunction. So, if you discover any leaks or cracks, you should schedule an inspection with Leak Science right away.

Causes of Swimming Pool Leaks

Tree Roots

What happens when tree roots grow into the swimming pool structure? Beautifully manicured swimming pool decks may provide a peaceful, lush ambiance, but tree roots can quickly make a mess of your hard work.

Poplar, ash, pine, and alder trees all have vast root systems that might eventually reach your backyard’s underlying foundation. As your trees grow, their roots seek water underground. And what better spot to find water than your pool’s plumbing? These root systems may break and lift concrete walkways, and they can even cause havoc with the construction of your swimming pool.

If you live near a large tree, it’s possible that it has caused leaks. By contacting a swimming pool leak repair firm, you can have the break evaluated, repaired and the root system removed to avoid further damage.

Seismic Forces 

Seismic pressure can cause swimming pool leaks, even though earthquakes are not as prevalent in Arizona as they are in other parts of the country. This pressure, which occurs deep under the ground’s surface, can build up and destroy swimming pool infrastructure.

The pressure can create movement in and around the pool, which can lead to leaks and breaks. Frequently seismic pressure is undetectable on the surface, and inhabitants are unaware that a quake has even happened.

Settling On The Ground 

The earth around your swimming pool will continue to settle and shift for a while after it is completed. The length of time it takes for the mud to settle is determined by your location as well as the type and quality of mud in your yard. An uneven foundation can cause cracks in your pool construction when the dirt settles around it to “settle” around it.  As the fractures widen, leaks may occur. Settling can also create leaks in and around plastic pool skimmers.

Pool Equipment That Is Getting Older

Pool equipment is made up of a variety of components and pieces that are joined by many connections. As your equipment ages and weathers, it may develop leaks. If your pool leaks on a regular basis, the source of the leak is most likely the pool equipment. Leaks in pool pumps are a regular occurrence.

A pump system uses pressure to pull in and push out water. Pump leaks usually begin as a trickle and rapidly progress to a visible leak. Swimming pool leaks might also be caused by failing seals. The seals are meant to keep water out, but they may leak as they age and break down.

Imbalance of Chemicals 

Chemicals are required to maintain your swimming pool and keep it sparkling clean.  Not only is chemical balancing necessary for the safety and hygiene of your swimming pool, but it is also necessary for pool upkeep. We understand how difficult it is to keep your pool’s chemical levels balanced, but the necessity of doing so cannot be overstated. An imbalance is harmful not only to the people who use your pool, but it may also harm the foundation and other components of your pool, causing weak places and leaks. When the chemicals in the pool are continuously out of balance, the water can harm the pool’s equipment, foundation, and other components.

A swimming pool leak detectors can locate the places in your pool that are generating the leaks.


Pool leaks can be caused by drastic temperature fluctuations. When the water in your swimming pool freezes, the water molecules expand, causing fractures and leaks. Leaks produced by cooler temperatures may not be visible right away, but if the hot Phoenix weather returns, they will be. Although Phoenix rarely sees freezing temperatures, it just takes one to cause serious damage.

For pool leak prevention and general pool upkeep, it’s critical to follow correct pool winterizing methods. You’ll need to close your pool securely for the winter, which may necessitate draining the water. If you don’t feel confident doing it yourself, we recommend hiring a professional to help you close and open your pool and check for winter damage.


If your pool has a hot tub or spa, the leak might be originating from there. Leaky hot tub fittings and seals might be the source of the problem, and they’re easy to ignore. The light fixtures are another typical source of leaks in hot tubs.

Because swimming pool leaks can be difficult to detect and analyze, it’s advisable to enlist the help of a professional. It is critical to act quickly to identify the source of the leak before it worsens. Ignoring the issue will almost certainly cost you more time and money in the end.

Plumbing and Pumps 

Underground leaks can result from corrosion or ground movement. Unless the damage is severe, PVC pipes may be simply repaired. They must then be replaced. Leak Science uses sophisticated sonar equipment to locate and repair a swimming pool leak from plumbing pipes beneath the decking. A return line leak does not necessitate tearing up the entire deck.

Check for leaks in the suction lines that bring water to the filter, heater, and chlorinator. This system begins with a skimmer, which is meant to keep debris out of the pipes. Pumps should be inspected for wear in the system as well. It’s possible that a new impeller or hose is required.
