My Buying Guides on 20 Gallons Of Water

When I first needed to purchase 20 gallons of water, I realized there were several important factors to consider to make the best choice. Here’s what I learned from my experience, which might help you too.

Purpose and Usage

Before buying, I asked myself why I needed 20 gallons of water. Was it for drinking, emergency storage, gardening, or perhaps for a large event? Knowing the purpose helped me decide on the type of water — whether purified, spring, distilled, or just tap water stored safely.

Type of Water

I found that water comes in various types:

  • Purified Water: Great for everyday drinking; free from contaminants.
  • Spring Water: Naturally sourced; tastes fresher but can be pricier.
  • Distilled Water: Ideal for appliances or medical use since it’s free from minerals.
  • Tap Water Storage: Economical for non-drinking uses if properly treated and stored.

Understanding these helped me pick the right water for my needs.

Packaging and Container Quality

Since 20 gallons is quite a volume, the container matters a lot. I preferred sturdy, BPA-free plastic or food-grade containers. Some come in stackable jugs or large water barrels. If you plan to reuse the container, ensure it’s durable and easy to clean.

Portability and Storage

I considered how I would transport and store the water. If you need to move it frequently, look for containers with handles or wheels. For storage, pick a cool, dark place to maintain water quality. Also, consider the footprint of the container to fit your space.

Cost and Value

Buying 20 gallons at once can be cost-effective, but prices vary by brand and water type. I compared prices per gallon and factored in delivery charges if applicable. Sometimes buying in bulk from a local supplier saved me money.

Shelf Life and Expiration

Water itself doesn’t expire, but stored water can develop off tastes or contaminants over time. I checked the packaging for recommended shelf life and storage instructions. For emergency preparedness, I rotated my stock regularly.

Additional Features

Some water containers come with spigots or pumps, which made dispensing easier for me. Others had UV protection to keep water fresh longer. These small features can make a big difference depending on how you use the water.

Final Thoughts

Buying 20 gallons of water isn’t just about the quantity but also about quality, convenience, and purpose. By considering these factors, I was able to choose water that suited my needs perfectly. I hope my guide helps you make an informed decision!
