Rain Barrel Myths: Garden Hoses and Water Collection


Rain barrels are a sustainable way to collect and store rainwater for use in your garden. They help conserve water, reduce utility bills, and promote eco-friendly gardening practices. While rain barrels are increasingly popular, there are persistent myths and misconceptions regarding the use of garden hoses in these systems. In this article, we will explore the role of garden hoses in rain barrel systems, dispel common myths about water quality, and clarify the importance of hose materials.

Fact: Garden hoses play a crucial role in rain barrel systems, but understanding their impact on water quality and choosing the right materials is essential for effective rainwater collection.

Myth 1: Rain Barrel Water Is Unsafe for Plants

Fact: Rain barrel water is typically safe for plants, provided you follow proper guidelines for installation and maintenance. The concern often arises from misconceptions about water quality. However, if you use an appropriate garden hose and maintain your rain barrel system correctly, the water is suitable for irrigation.

Garden hoses can be an essential part of a rain barrel system, helping you distribute collected rainwater to your plants. To ensure the water remains safe, choose a garden hose labeled as “drinking water-safe.” These hoses are designed to meet specific health and safety standards and are less likely to introduce contaminants into the water.

Myth 2: Garden Hoses Always Contaminate Rain Barrel Water

Fact: While it’s true that some garden hoses can introduce contaminants into the water, not all hoses are created equal. The risk of contamination depends on the materials used in the hose and its age. As mentioned earlier, using a drinking water-safe hose reduces the likelihood of contaminants leaching into the collected rainwater.

When setting up a rain barrel system, it’s important to take precautions. Make sure that the hose you use is made from materials that are safe for potable (drinking) water. Avoid using old or damaged hoses, as they are more likely to introduce impurities into the rainwater.

Myth 3: Rain Barrel Water Is Not Suitable for Edible Plants

Fact: Rain barrel water can be used for edible plants, but certain precautions are necessary. While it may not be advisable to use rainwater from a barrel to directly irrigate edible crops that you consume without treatment, it can be used for watering the soil around these plants.

To ensure safety, follow these recommendations:

  • Use a drinking water-safe garden hose to minimize the introduction of contaminants.
  • Avoid direct contact between rainwater and edible parts of the plants.
  • Implement a filtration or treatment system if you intend to use rainwater for drinking or watering edible plants.

Selecting the Right Garden Hose

Choosing the right garden hose is crucial for maintaining water quality in your rain barrel system. Here are some considerations when selecting a garden hose:

  1. Materials: Opt for a hose made from materials that are safe for potable water. Rubber hoses are often a better choice than PVC hoses for this purpose, as they typically have fewer chemical additives.
  2. Drinking Water-Safe: Look for hoses labeled as “drinking water-safe” or “potable water-safe.” These hoses are explicitly designed for use in systems where water quality is a concern.
  3. Age and Condition: Avoid using old or damaged hoses, as they are more likely to introduce impurities into the collected rainwater. Regularly inspect and replace hoses as needed.
  4. Hose Length: Consider the length of the hose you need for your rain barrel system. Excess hose length can lead to stagnant water and potential contamination if not properly maintained.

Maintenance Tips for Rain Barrel Systems

To ensure the water collected in your rain barrel remains safe and suitable for use in your garden, follow these maintenance guidelines:

  1. Regular Cleaning: Clean your rain barrel and the inlet filter at least once a year to prevent the buildup of contaminants, sediment, and algae.
  2. Cover the Barrel: Ensure your rain barrel is covered to prevent debris, insects, and sunlight from entering. This helps maintain water quality.
  3. Overflow Management: Install an overflow system to divert excess water away from the barrel to prevent overflows that can carry contaminants into the water.
  4. Water Filtration: Consider using a first flush diverter or a filtration system to remove initial runoff and debris before the water enters the barrel.


Rain barrel systems are valuable tools for sustainable gardening, water conservation, and reducing utility bills. However, myths and misconceptions about the role of garden hoses and water quality can create unnecessary worries. By understanding the importance of using the right materials, choosing a drinking water-safe hose, and following maintenance guidelines, you can enjoy the benefits of rainwater collection without compromising the safety and suitability of the water for your plants. Rain barrel systems, when set up and maintained correctly, are a fantastic way to promote eco-friendly gardening practices and make the most of nature’s gift.
