large leaking swimming poolIf you are a regular user or are involved in cleaning your pool; if anything abnormal occurs, you can easily detect it. One of the possible abnormalities that may occur in a pool is drastic water loss which is a symptom of possible water leak in the pool.

On average an ordinary Swimming pool loses roughly a quarter of an inch of water per day depending on where in the world your pool is. However, this may fluctuate due to sunlight, humidity, and wind intensity. The primary causes of causes of abnormal loss of water in your pool include;

A lifting or sinking pool deck

The pool system having air

The emergence of soggy spots surrounding the pool

Cracks in the pool

Adding water in the pool too frequently

Dangers of a leaking pool;

  • It can lead to dangerous sinkholes.
  • It can lead to high water bills
  • Poor management of swimming pool pH due to debris entering via the leaking spots. It can also lead to often growth of algae and bacteria in the pool.

Causes of False Pool Leaks in a swimming pool

Losing water in a pool is normal due to several factors like splashed water while swimming and evaporation. However increased sudden loss may not necessarily be a water leak, below are some of the possible causes;

  • Temperature: Some parts of the world can get really hot, and even the nights remain warm, resulting in high evaporation rates on the pool.
  • Higher exposure: If your pool gets more exposure to sun rays evaporation will increase reducing water levels. This can be controlled by shading your pool or screening.
  • Humidity: Low humidity outside the pool sucks the pool water at a high capacity.

Having considered the above false alarms not to be a cause of abnormal water loss in your swimming pool, then the next step to take is using the bucket test. The following are procedures of a bucket test;

  • Fill a regular normal bucket with pool water: Using the same pool water fill a regular bucket with water to 1-2 inches from the top of the rim. The purpose of using the same pool water is to ensure you have the same temperatures.
  • Carefully place the bucket in the pool: Position the bucket inside the pool in a way the bucket is in level with the waters in your swimming pool. The best place to place it is on the pool steps. To ensure the bucket is held in place put something heavy into the bucket.
  • Make marks of the water level: Mark the water levels inside and outside the bucket using a tape or a water resistance marker.
  • Monitor and wait for 24hrs: Ensure unnecessary disturbance of the pool for 24 hours then observe the water levels in the bucket and swimming pool. If the water level in the bucket and pool remain the same, then there is no leak in the pool, but if the water levels in the pool have dropped more than the water in the bucket, then there is cause for alarm for a possible leak in the pool.
  • Repeat the test under different conditions: Have test repeated under different conditions to establish where the leak might be. Repeat the test with the pool pump off. The following results could further help stipulate where the leak is.

Losing more water when the pump is off means the leak is more likely to be located in the return lines.

Loosing less water when the pump is off means the leak could be in the skimmer or main drain.

If the loss of water is the same whether the pump is off, or on means, the leak could be either in the fittings, pool liner or shell.

Establishing the exact location of a leak in a pool

Having confirmed the possibility of a leak in a pool, the next step is locating the exact position of the leak in a swimming pool. Below is a simple step by step swimming pool hack referred to as ‘The Dye Trick’ used to locate the actual spot of a swimming pool leak.

  • Arm yourself with some dye: Purchase some dye or food coloring to be used to run the procedure.
  • Time to get wet: For safety precautions have some water goggles and snorkel to assist you while underwater, which takes some time. Don’t forget to carry the dye with you.
  • Procedure: While underwater ensures not to disturb the water too much, get to the area with visible cracks or if there are no such areas get to obvious hotspots like return lines and main drain. Release the dye and monitor where the dye gets sucked. That reveals the exact leakage spots in your swimming pool.
