Whether I’m watering plants, washing my car, or even using it as a backup for household water supply, this size provides enough volume without the hassle of frequent refills. It’s also easier to move or install compared to larger tanks, which makes maintenance simpler and less time-consuming.

My Buying Guides on 20 Gallon Water Tank
When I first decided to purchase a 20 gallon water tank, I realized there were several important factors to consider to make the right choice. Here’s what I learned from my experience that might help you find the perfect tank for your needs.
1. Determine Your Purpose
Before anything else, I asked myself why I needed a 20 gallon water tank. Was it for drinking water storage, irrigation, emergency preparedness, or maybe for an RV or camping? Knowing the primary use helped me narrow down the options significantly.
2. Material Matters
Water tanks come in different materials like plastic (polyethylene), stainless steel, or even fiberglass. I chose a food-grade plastic tank because it was lightweight, affordable, and safe for potable water. If you need something more durable or for industrial use, stainless steel might be better.
3. Size and Dimensions
Though the capacity is fixed at 20 gallons, tanks vary in shape and dimensions. I measured the space where I intended to place the tank to ensure it would fit comfortably. Some tanks are tall and narrow, others are short and wide—choose what suits your storage area best.
4. Portability and Weight
Since I planned to move the tank occasionally, I looked for lightweight options with handles or molded grips. A full 20 gallons weighs around 166 pounds, so portability features are crucial if you need to transport it.
5. Opening and Access Points
I checked the size of the tank’s opening to make sure it would be easy to fill and clean. Some tanks come with threaded lids or additional spigots for easy water dispensing. These features made my daily use more convenient.
6. UV Resistance and Durability
Because my tank would be stored outdoors, I needed one with UV protection to prevent degradation and algae growth. Many polyethylene tanks come with UV inhibitors, which significantly extend their lifespan.
7. Price vs. Quality
I compared prices across different brands but didn’t just pick the cheapest. I wanted a tank that would last several years without leaks or cracks. Reading customer reviews helped me find a good balance between cost and quality.
8. Additional Features
Some tanks come with extras like built-in handles, stackable designs, or compatibility with pumps and filters. These little bonuses enhanced my overall experience and made maintenance easier.
9. Maintenance and Cleaning
I looked for tanks that were easy to clean because stagnant water can lead to contamination. A wide-mouth opening and smooth interior surface made cleaning much simpler for me.
10. Warranty and Customer Support
Finally, I checked if the manufacturer offered a warranty or good customer support. It’s reassuring to know you have assistance if something goes wrong.

By considering these points, I found a 20 gallon water tank that perfectly fit my needs. I hope my buying guide helps you make a confident and informed decision!
