Fountains are a great addition to any outdoor space, providing a soothing and relaxing atmosphere. The calming flow of water can bring tranquility and sophistication to your outdoor area. However, it can be frustrating when you notice that your outdoor water fountain is losing water. Not only does this affect the aesthetic appeal of your fountain, but it can also be a sign of a bigger problem. Water features are a beautiful addition to any outdoor space, but they require regular maintenance to keep them in good working order. 

Here are the top reasons why your fountain is losing water.

1. Evaporation

The most common reason for fountain water loss is evaporation. Evaporation occurs when water is exposed to air and heat, causing it to turn into vapor. This process is accelerated in areas with high temperatures and low humidity. To prevent excessive water loss due to evaporation, fountain owners can take the following steps:

  • Fill the fountain with water to the appropriate level.
  • Keep the fountain in a shaded area, away from direct sunlight.
  • Use a fountain cover to reduce exposure to air and heat.
  • Add a fountain water treatment to slow down the rate of evaporation.

2. Splash and Splatter

Splash and splatter occur when water is thrown out of the water fountain due to the movement of the water or the wind. This can cause a significant amount of water loss over time. To prevent splash and splatter, fountain owners can take the following steps:

  • Adjust the water flow to reduce movement.
  • Use a fountain nozzle to direct the water flow.
  • Place rocks or other decorative elements around the fountain to absorb splatter.

3. Leaks and Cracks

Leaks and cracks are the least common reason for fountain water loss, but they can cause significant damage if left untreated. Leaks can occur due to damaged or worn-out fountain components, such as pipes or hoses. Cracks can occur due to exposure to extreme temperatures or physical damage. To prevent leaks and cracks, fountain owners can take the following steps:

  • Regularly inspect the fountain for signs of damage or wear.
  • Repair any leaks or cracks as soon as they are detected.
  • Use a fountain sealant to prevent future leaks or cracks.

4. Weather Conditions

Weather conditions can have a significant impact on the water level in your outdoor water feature. Wind can cause water to evaporate quickly, especially in hot and dry climates. Rain can also cause water loss if your water fountain is not designed to handle large amounts of water. Therefore, it is essential to consider the weather conditions in your area when choosing the location and design of your outdoor water feature.

5. Fountain Design Flaws

Fountain design flaws can also lead to water loss. Low edges or gaps in the fountain can cause water to leak out, while improper fountain architecture can cause water to splash out. Therefore, it is crucial to choose a fountain design that is suitable for your outdoor space and to ensure that the edges are high enough to prevent water loss.

6. Faulty Plumbing

Faulty plumbing is another common cause of water loss in fountains. Leaks or clogs in the plumbing system can cause water to escape, leading to a drop in the water level. Regular maintenance and inspections of the plumbing system can help prevent water loss and ensure that your garden fountain is functioning correctly.

7. Water Quality and Algae Growth

The decline in your fountain's water level may be attributed to water quality issues and algae growth. Poor water quality, marked by an excess of organic matter and pollutants, can accelerate evaporation and compromise water retention. Additionally, the presence of algae can contribute to water loss, as these organisms absorb water and create a barrier that accelerates evaporation.

How to Prevent Water Loss in Your Fountain

To prevent water loss in your outdoor fountain, there are several preventative measures that can be taken. These measures include regular maintenance, improving fountain design, and water conservation techniques.

1. Regular Maintenance

Regular maintenance is key to preventing water loss in your fountain. This includes cleaning the fountain regularly to remove debris and algae, checking the fountain's water flow, and ensuring that the fountain's pump is functioning properly. It is also important to check for leaks and to seal them promptly using a sealant.

2. Improving Fountain Design

Improving the design of your outdoor fountain can help to minimize water loss. One way to do this is to cover the fountain when it is not in use, which can help to prevent evaporation. Additionally, adding a recirculating system to your fountain can help to conserve water by recycling the water that is already in the fountain.

3. Water Conservation Techniques

Water conservation techniques can also help to prevent water loss in your fountain. These techniques include minimizing evaporation by adding a cover to your fountain, using a low-flow pump, and using water conservation methods such as rainwater harvesting to conserve water.

4. Sealing and Fixing Cracks

Over time, your outdoor fountain may develop cracks that can cause water to leak out. To prevent this, it is important to seal any cracks as soon as possible. You can use a sealant to fill in the cracks and prevent water from escaping.

If the cracks are too large, you may need to call a plumber to fix the problem. A professional plumber can assess the damage and recommend the best course of action.

5. Pump and Plumbing Maintenance

The pump and plumbing system are critical components of your garden outdoor fountain. Regular maintenance can help prevent leaks and other problems. You should clean the pump and plumbing system regularly to remove any debris that may be clogging the system.

It is also important to check the pump and plumbing system for leaks. If you notice any leaks, you should fix them immediately to prevent water loss.

6. Managing Water Quality and Algae Growth

Water quality and algae growth can also affect your fountain's performance. You should regularly test the water quality and adjust the pH levels as needed. You can also use an algaecide to prevent algae growth.

Regular cleaning can also help prevent algae growth. You should clean the fountain regularly to remove any debris or algae that may be present.

By following these tips, you can keep your outdoor water fountain in good condition and prevent water loss. Regular maintenance and repair can help you avoid costly repairs and ensure that your outdoor water feature lasts for years to come.


Addressing the reasons behind your fountain's water loss is essential for its longevity and efficiency. By understanding and mitigating factors such as leaks, evaporation, and water quality issues, you can ensure a consistently enchanting and functional water feature. Regular inspection, proper maintenance, and timely repairs are pivotal in preventing unnecessary water loss. Implementing these preventive measures will not only sustain your fountain's water levels but also enhance its aesthetic appeal, providing a lasting and captivating addition to your outdoor space. With proactive care, your fountain can flourish, bringing joy and tranquility for years to come.
