How Does the Swimming Pool Water Loss Calculator Work?

Our swimming pool water loss calculator is designed to be user-friendly and highly accurate. For rectangular pools, you will need to know your pool’s length and width. For circular pools, you will need to know the diameter. Additionally, you’ll need to measure the amount of water lost each day in inches. With this information, the calculator will estimate the number of gallons lost per day and per hour, helping you understand the size and severity of the potential leak.

    Where Does Water Go When a Pool Leaks?

    When a pool leaks, the escaping water generally soaks into the soil surrounding the pool area. Over time, this can lead to soil displacement and structural damage to the pool itself and even your home’s foundation. It’s also important to understand that leaks don’t stop at the property line. Water leaking from your pool may find its way to your neighbor’s yard, potentially leading to costly repairs for which you could be liable. Therefore, it is crucial to address pool leaks promptly to prevent further complications and to conserve as much water as possible. That’s where our swimming pool water loss calculator comes in. It can help you know if you have a problem that needs to be addressed long before harm is done to your property or your neighbor’s.

    Is Your Water Loss Due to Pool Evaporation or a Leak?​

    Determining whether your pool’s water level decrease is due to evaporation or a leak can be challenging. Various factors, such as air temperature, water temperature, relative humidity, and wind speed, affect the evaporation rate. A simple and effective method to distinguish between natural evaporation and a leak is the bucket test. By comparing the water loss in a bucket placed on a pool step to the water lost in the pool, you can estimate the evaporation rate and identify larger water loss issues due to leaks. After performing the bucket test, use our pool water loss calculator to determine if the amount of water you lost in a day is normal or excessive. A normal pool evaporation rate is ¼” per day. If your pool’s water level decreases more than this within 24 hours, it’s time to contact a specialist to repair the pool leak right away.

    How to Identify a Pool Leak

    Here are some tell-tale signs that your pool might be losing water excessively:
    • Decreased Water Level: If your pool’s water level decreases faster than normal, this could indicate a leak. Remember, some water loss due to evaporation is normal, especially during hot, dry weather. But adding more water every day or every few days is not a good sign.
    • Cracks or Damage on the Pool Surface: Physical signs such as cracks, gaps, or flaking on the pool surface or around the pool area can be indicative of a leak.
    • Soggy Soil Around the Pool: Unusually wet or soggy soil around the pool area, especially when it hasn’t rained recently, could be a sign of a leak.
    • Algae Growth: If algae persistently appear despite regular cleaning and chemical treatment, it may be a sign of a leak diluting the pool chemicals.
    If you notice any of these signs, it’s important to act quickly. Contact our pool experts to diagnose and fix the problem before it escalates.
