Detecting a leak in a pool can be crucial to prevent water loss, avoid damage to the pool structure, and save on water and chemical costs. Here are some common signs that can indicate a pool leak:
Significant Water Loss: It's normal for pools to lose some water due to evaporation and splash-out, especially during hot and windy weather. However, if you notice a significant and unexplained drop in the water level (more than about 1/4 inch per day), it may be a sign of a leak.
Persistent Air Bubbles: If you see air bubbles coming from the return jets when the pool pump is running, it might indicate that air is being drawn into the system through a crack or hole, which could be a leak point.
Wet or Soft Spots: Check the area around the pool for wet or soft spots, especially if the ground feels soggy or unusually moist. This could be a sign of water seeping out from the pool.
Increased Water Bills: If you have an automatic fill system and notice a sudden increase in water bills, it might indicate that your pool is losing water at a faster rate than usual.
Algae Growth: A leak can disrupt the water balance in the pool, leading to difficulty maintaining proper chemical levels. Algae growth or difficulty in maintaining water clarity might be a sign of a leak.
Cracks or Damage: Inspect the pool's structure, including the walls, floor, and the area around fittings and skimmers, for any visible cracks or damage that could be potential leak points.
Unusually Low Skimmer Water Level: If the water level in the skimmer is too low, it might indicate that the pool is losing water faster than the skimmer can keep up.
Pressure Loss in Pool Equipment: If you notice a decrease in water flow and pressure from the pool jets or other pool equipment, it might be due to a leak affecting the system's efficiency.
If you suspect your pool has a leak based on these signs, you can perform a simple bucket test to confirm the leak. Here's how:
- Fill a bucket with pool water to the same level as the pool.
- Place the bucket on the pool step or bench, making sure the water level inside the bucket matches the pool water level outside.
- Mark the water level inside the bucket and on the pool wall.
- Turn off the pool pump and mark the water levels again after 24 hours.
- If the pool water level has dropped significantly more than the water level inside the bucket, it indicates a probable leak.
If you suspect a leak, it's best to contact a professional pool leak detection service to pinpoint the exact location of the leak and recommend the appropriate repair. They have specialized tools and methods to find and fix leaks without unnecessary damage to the pool structure.
