A pool leak can be a perplexing and concerning issue for any pool owner. And you can’t help but wonder where does water go when pool leaks happen. Not only does it waste water, but it can also lead to significant damage if left unaddressed. Understanding where the water goes when your pool leaks is crucial for identifying the source and taking appropriate measures to fix the problem. In this blog, we will explore five possible destinations for the water when your pool has a leak.

1. Where Does Water Go When Pool Leaks? Into the Surrounding Soil.

One of the most common places for where does water go when pool leaks is into the surrounding soil. This type of leak can be challenging to detect, as the water seeps into the ground rather than forming visible puddles. Here’s how it happens:

  • Cracks in the Pool Shell: Over time, concrete pools can develop cracks due to shifts in the ground, temperature changes, or structural stress. Water escapes through these cracks and saturates the soil around the pool.
  • Leaking Plumbing: The pipes and fittings that circulate water in and out of the pool can develop leaks. These leaks may go unnoticed until a significant amount of water has escaped into the soil.

Indicators: Look for areas of the yard that are unusually wet or have lush, green grass. Soil erosion or sinkholes near the pool can also indicate water seeping into the ground.

2. Evaporation and Wind

While evaporation and wind do not technically constitute a leak, they are worth mentioning as they can contribute to water loss in a pool. Evaporation occurs naturally, especially in hot climates or during the summer months. Wind can increase the rate of evaporation by moving moisture away from the pool surface.

  • Evaporation: Pools can lose significant amounts of water due to evaporation, particularly if they are not covered when not in use.
  • Wind: Windy conditions can exacerbate evaporation, leading to faster water loss.

Indicators: To determine if evaporation is the primary cause of water loss, perform a bucket test. Place a bucket filled with water on a pool step, ensuring the water levels inside the bucket and the pool are the same. After 24 hours, compare the water levels. If the pool level drops more than the bucket level, you likely have a leak.

3. Underground Plumbing

Another common destination for water from a leaking pool is underground plumbing. This type of leak can be particularly problematic, as it often requires professional intervention to locate and repair.

  • Pressure Side Leaks: These occur after the pump, typically in the return lines. Water escapes from the pipes and can erode the surrounding soil.
  • Suction Side Leaks: These happen before the pump, often in the suction lines. These leaks can draw in air, causing the pump to lose prime and potentially damage the motor.

Indicators: A decrease in water pressure, air bubbles in the pool, or unusually high water bills can indicate a leak in the underground plumbing.

4. Into the Pool Equipment Area

Leaks can also occur in the pool’s equipment area, where various components like the pump, filter, heater, and chlorinator are located. Water leaking from these components can pool around the equipment or seep into the ground.

  • Pump and Filter: Leaks around the pump and filter are common due to worn seals, gaskets, or cracks in the housing.
  • Heater and Chlorinator: These components can also develop leaks, particularly if they are not maintained regularly.

Indicators: Inspect the equipment area for standing water or dampness. Listen for unusual sounds from the pump, such as hissing or gurgling, which can indicate air or water leaks.

5. Into the Pool Structure Itself

In some cases, water from a leaking pool may find its way into the pool’s structure, such as behind the tiles or within the pool walls. This type of leak can be tricky to detect but can cause significant damage if not addressed.

  • Tile and Coping Leaks: Water can seep behind loose or cracked tiles and coping, leading to deterioration of the pool structure.
  • Structural Leaks: Cracks or voids within the pool’s structure can allow water to infiltrate, potentially causing further cracking and damage.

Indicators: Look for loose or damaged tiles, cracks in the pool surface, or areas where the pool structure appears damp or discolored.

Preventive Measures and Repair

Preventing and repairing pool leaks requires regular maintenance and prompt action when issues are detected. Here are some tips:

  • Regular Inspections: Conduct routine inspections of your pool, looking for signs of wear and tear, cracks, or loose tiles.
  • Professional Assessments: Schedule regular check-ups with a professional pool technician to identify and address potential leaks early.
  • Proper Winterization: If you live in a region with cold winters, ensure your pool is properly winterized to prevent freeze damage. Check out our leak supply store for winterization plugs and more

Conclusion

Understanding where does water go when pool leaks is essential for effective diagnosis and repair. Whether the water is seeping into the soil, escaping through underground plumbing, or causing damage within the pool structure, prompt action is crucial to prevent further complications. Regular maintenance and professional inspections can help you keep your pool in top condition and minimize the risk of leaks. If you suspect your pool has a leak, don’t hesitate to contact a professional pool leak detection company to ensure the issue is resolved quickly and efficiently.
